(3) Name the antagonistic muscle and explain how it will be affected with mention of the physiological changes that may occur. (5) b) c)

Explanation / Answer

a). Elbow and shoulder. Most likely site for the injury to occur is Long head of the biceps tendon.

b). Biceps tendon is a two- joint muscle.

--> Shoulder Joint

--> Elbow Joint

Shoulder Joint muscle enforces opposite movements. Long head pulls away the arm from the abduction whereas short head pulls in back the arm( adduction). When these both the heads contract it leads to arm bend. That condition is known as Flexion.

Biceps tendon tear mostly occurs at the elbow when it is forced against the resistance. When the tendon cannot resist the sudden weight that had been carried it leads to tendon tear condition.

c). Triceps is the antagonisitic muscle. When these agonist and antagonisitic muscles are damaged, several physiological changes can be observed.

1. Pain

2. Loss of strength

3. Bruising

4. Swelling

5. Complete tendon tear

6. Muscle tenderness.
