Three Types of Muscle and their functions
There are three types of muscle, each with a different structure and function. Skeletal muscle produces the most powerful contractions and is essentially involved in performing the body's movements. Skeletal muscle is under conscious control and is therefore described as voluntary. It is composed of cells, elongated up to twelve inches in length, containing many minute myofibrils and nuclei. It can contract and relax rapidly, but is easily fatigued. Smooth muscle is found in the arteries and in the digestive and urinary tracts, and performs the slow, long-term contractions needed to maintain these systems. Smooth muscle is made up of elongated cells arranged in bundles, each with a single nucleus. Within the intestines an inner circular band produces ring-like constrictions and an outer longitudinal band produces wavelike motions. Controlled by the autonomic system, smooth muscle contraction is involuntary. Cardiac muscle, found exclusively in the heart, continuously generates very strong contractions and rarely tires in its task of pumping blood throughout the body. It has a built-in rhythm of contraction, but is regulated by the heart's pacemaker. Cardiac muscle forming the heart is made up of branched cells containing many nuclei. It occurs as thick spiral bands around the ventricles of the heart.[By Dizzo95]

Hearing Test-AUDIOMETRY

2009-02-18T21:57:00.000-08:00

(1)First determinine the hearing range ( at the lowest value of Hz).

(2)Then use this value of Hz (hearing frequency) for determining the LOUDNESS TEST.

Procedures Of Hearing Test FOR LOUDNESS (Db)---I Used In Teaching Medical, Dental and Pharmacy StudentsBased On the Audiometer as shown in the following in the YOUTUBE:

1. Increase the loudness (Db) say 5 DB from 5 DB at the start.==5db, 10db,15db,20db.......till the subject indicates sound is heard.(take the lowest reading, when the subject start perceive the hearing)

do Do it in a quiet place.

usiUsing a Earphone.

TeTest the hearing on one ear at a time.(block the other ear which is not being tested at that moment--There is a switch indicating sound is supplied to LEFT/RIGHT ear on the audiometer)

Focus on the hearing and pin-point(indicate to the tester) at which DB when you begin to hear. Repeat a few times for consistent results. [N.B. Audiometer can do the 2 tests at one sitting

Diabetes is the leading cause of preventable new onset blindness in working age adults. You can have diabetic eye disease and not know it as it is painless and often has no symptoms until very advanced stages. Deborah K. Schlossman, M.D., of the Beetham Eye Institute at Joslin Diabetes Center, explains why an annual eye exam and appropriate care can reduce the risk of blindness and increase your chances of preserving sight.

Blind spot mapping with chiropractor Don

Chiropractor Don Coil (Kiropraktik Wellness, Gärdet, Stockholm, Sweden) tells us about chiropractic and chiropractic examination. He shows us an examination technique known as 'Blind spot mapping'. The technique examines the size and shape of the blind spot. The test is performed with the computer program Clinicbuddy. Chiropractic is a unique art, science and philosophy whereby the practitioner, without the use of drugs or surgery, stimulates the body’s own forces to maintain and heal itself from within. Pain represent only 10% of nerve signal transmission, therefore a thorough examination should not be based entirely upon pain, as an absence of symptoms is not a guarantee of health. Chiropractor Don Coil can be found in Stockholm Sweden, http://www.kiropraktikwellness.se The computer program Clinicbuddy is used by many chiropractors and other healthcare providers. http://www.clinicbuddy.com/

Skeletal Muscles

2009-02-13T21:55:00.000-08:00

There are over 600 skeletal muscles! Scientists have developed seven general naming criterias to help distinguish and keep track of them all. The muscular system is the largest part of the human body. It makes up about half of the body’s weight.
· The largest muscle in the body is the gluteus maximus. The smallest muscle is the stapedius.
· Repetitive Strain Injury (RSI) happens to people who repeat finger actions. E.g. Piano players.
· Many sport coaches find going over actions in your mind can help muscular skills.· Oxygen is needed for your muscles to burn glucose to obtain energy. This process is called respiration

Movement of the Joints
Movement of the body's skeleton is made possible by a number of body parts working together including the joints. A hinge joint at the elbow allows the arm to bend and extend. The condylar joint at the knee gives similar movement plus some rotation. Mobile ellipsoid joints between the fingers and palm of the hand allow circular movements but no rotation. Ball-and-socket joints, like the one at the shoulder, give maximum freedom of movement. At the other extreme, plane joints between the toe bones permit only a small degree of gliding movement and the pivot joint between the two cervical vertebrae-the atlas and the axis-merely provides rotation of the head. The saddle joint at the ankle is almost as mobile as the shoulder joint, but rotation is far more limited.

Xenophanes21 ="It doe$n’t take hundred$ of thousand$ of dollar$ to have great teacher$ anymore. Thank you UCBerkeley and Wikipedia for allowing me to study things that I wouldnt necessarily spend money to learn. In an academic landscape which is increasingly multidisciplinary, such technologies need to be developed to disseminate information on disciplines which are on the periphery of your professional training. Great tool for continuing education."

Clinical Skill On Medical Examination
The Clinical Skills Online (CSO) is a project aimed at providing online videos demonstrating core clinical skills common to a wide range of medical and health-based courses.
This project has been funded by the Higher Education Academy Subject Centre for Medicine, Dentistry and Veterinary Medicine.

Lower Back Disorders; Disc Herniation, Lumbalgia, Sciatic Nerve Neuralgia, Post-Isometric Relaxation & Back Rehabilitative Exercises.
Sciatic nerve neuralgia is considered to be one of the most difficult abnormalities of the support and movement system. Clinical expressions of sciatic nerve neuralgia include sharp pain irradiating to the lower extremities which increases during any of the patient's attempts to move and of course limited range of motion on all axes and planes. Usually, when a patient appears at the doctor's office with such a difficult clinical picture, in addition to prescribing painkillers, anti-inflammatory drugs, and/or utilizing injections, the doctor will usually refer the patient for radiological examination. Today, the most common radiological examinations are the MRI and/or CT scan. In many cases, MRI test detects bulging and/or herniation of discs. If symptoms are not alleviated in a period of a few weeks due to conservative methods of treatments (above mentioned oral or injected medication) consideration will be given to surgical intervention. The problem is that in many cases, this difficult neurological picture is not the result of the disc herniation, but is actually the result of piriformis muscle syndrome.
Anatomy of the Piriformis Muscles
The Piriformis muscle originates from the anterior surface of the sacrum and inserts into the greater trochanter. It shares the passage through the greater sciatic foramen with several important nervous and vascular structures including nerves which provide innervation to pelvic inner organs, the gluteals, and the lower extremities. The piriformis muscles can accumulate tension to the point that they will start compressing/ impinging sciatic nerve and awaking in some cases intolerable pain in the buttocks and lower back with irradiation to the extremities.
Sciatica nerve neuralgia can be the result of compression of the S1 spinal nerve as well as due to the compression of the sciatic nerve by over-tensed piriformis muscles. If patients with symptoms of sciatica have the ability to bend forward without awaking pain, most likely the sciatica neuralgia is the results of piriformis muscle syndrome.
The Causes for Accumulation of Tension in the Piriformis Muscles
1. Due to spondylosis, including herniation of disc, spinal nerves can be irritated (please do not confuse irritation of the spinal nerve with compression of the spinal nerve.) Irritation of the spinal nerves that provide innervation to the piriformis muscles (S1 spinal nerve) will cause a gradual accumulation of tension in these muscles, to the point that they will compress the sciatic nerve.
2. Physical overload of the muscles such as vigorous exercise, job performances that put too much static load on the piriformis muscles, hormone changes, exposure to toxins, physical and/or psychological trauma, etc.

Body Worlds

BODY WORLDS

Throughout the ages, medical scholars and students have strived to understand how our bodies function through exploration of real human specimens. Gunther von Hagens' BODY WORLDS, the most highly attended touring exhibition in the world, takes this tradition one step further by presenting a new look at the human body.

Take an eye-opening journey through the inner workings of the human body, exploring specific areas including the locomotive, nervous, respiratory, circulatory, cardiovascular, digestive and reproductive systems. See muscles, bones and tendons that help us move; study the parts and organs that allow us to fuel our bodies; view the complex pathways of our vascular system; and realize how human life is made possible.

This original and unprecedented exhibition of real human bodies features about 200 authentic human specimens, including whole-bodies, individual organs and transparent body slices that have been preserved through the process of Plastination, a revolutionary specimen preservation process that was invented by Dr. von Hagens in 1977, which replaces bodily fluids and fat with reactive plastics. The specimens on display were generously willed by body donors during their lifetime for the express purpose of Plastination and educational enlightenment. BODY WORLDS 3 offers a once-in-a-lifetime chance to see and understand our own physiology and health and to gain new appreciation and respect for what it means to be human.

How the Body Works : Control of Involuntary Muscle and the Anatomy of the Central Nervous Syst

2009-02-06T18:29:00.000-08:00

The Anatomy of the Central Nervous System

The nervous system is a complex network of nerve cells and nerve fibers spread throughout the body. Its function is to interpret, store, and respond to information received from inside and outside. The central nervous system or CNS, consists of the brain and spinal cord and is responsible for processing information gathered from the rest of the nerves and transmitting instructions to the body. Messages passing to and from the CNS are carried by the nerves of the peripheral nervous system. This system includes twelve pairs of cranial nerves and thirty-one pairs of spinal nerves. The cranial nerves and the spinal nerves control voluntary movements and sensations. The autonomic nervous system, consisting of sympathetic and parasympathetic nerve fibers, controls such involuntary body functions as the heartbeat.

Control of Involuntary Muscle

Cardiac muscle and smooth muscle function involuntarily-beyond our conscious control. There is smooth muscle in organs of the digestive, respiratory, circulatory and urinogenital systems, while cardiac muscle is found exclusively in the heart. These muscles are controlled by the autonomic nervous system, which is composed of two opposing divisions, the sympathetic, shown in red, and the parasympathetic, shown in blue. Sympathetic nerves leaving the spinal cord lead first to nearby nerve chains before connecting the body organs, where they stimulate muscle activity. In the parasympathetic division, nerves pass from the spinal cord directly to the organs and have the opposite effect-decreasing muscle activity. This dual mechanism provides a method for maintaining the activity of the muscles within controlled limits. The sympathetic system is dominant in situations requiring rapid action. When, for example, danger threatens there is an increase in heart rate, respiration rate, blood pressure and sweat gland activity. The parasympathetic system is dominant while the body is resting-usually during sleep, when the heart rate is slower and respiration is deeper and more regular.
