Anatomy of "Magic Wands"

Anatomy of "Magic Wands" 

Part-2

In the second part of this series we are going to discuss about the muscle anatomy of the fore limbs.The muscle system in the arm and hand consists of both large and small muscles. We can also find exceptional amount of tendon tissue all over the fore limb.

     

        The interesting thing about arm is that the muscle groups are divided into two fascial layers namely lateral and medial inter muscular septa. These layers divide the muscle groups into two different compartments. The important thing about limbs is that they are responsible for flexion and extension of themselves that helps us to carry out almost every movement that takes place by limbs.

The basic naming involving muscle is carries out on the character of the muscle and is place. For example the brachioradialis is the big strapped muscle that we observe to pop out while flexion near the elbow joint. This muscle is named so because it is found at the brachial side of the radius bone.

 

The list of Muscle Involved in following movements-

Flexion of fore arm-                                                             

• Brachialis
• Biceps Brachii
•  Brachioradialis

The Supination of forearm-

• Bicep Brachii

The extension-

• Triceps brachii

The extensor muscles-

• Triceps Brachii (Posterior)
• Carpi Ulnaris (Posterior)
•  Extensor Digitorum (Posterior)

Flexion Muscles

• Flexor Carpi Radialis
• Flexor Digitorum Suerficialis

Carpal tunnel

The flexor and extensor muscles pass through a narrow tunnel at our wrists called carpal tunnel. The tendons of these muscles pass through the tunnel to connect with the phalanges and other bones in the hand. Some time due to incorrect posture or over work a strong inflammation occurs in the carpel tunnel due to extensive stress on median nerve by localized swelling of tendons or muscles.This causes numbness and inability to do griping work. This is called Carpel tunnel syndrome.
