APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -An example of the fusiform muscle is m. biceps brachii. Some muscles have tendinous tissue within the muscle belly and the muscle fibers are inserted to the intramuscular tendons forming angles, which gives them a feather-like appearance, hence the name of penniform muscles .

Detailed explanation-2: -The biceps brachii is an example of a fusiform parallel muscle, and is responsible for flexing the forearm.

Detailed explanation-3: -The biceps are classified as skeletal muscles because they attach directly to the skeleton.

Detailed explanation-4: -Muscles designed for strength (e.g., gastrocnemius) are typically pennate, whereas those designed for speed (e.g., biceps) tend to have parallel fibers.

Detailed explanation-5: -The biceps tendon is a bipennate muscle comprising a short and a long head. The long head originates from the supraglenoid tubercle and the short head from the coracoid process.
