APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -An example of the fusiform muscle is m. biceps brachii.

Detailed explanation-2: –Smooth muscle cells are fusiform in shape meaning that they are wide in the middle with tapered ends, they also have only a single nucleus.-Smooth muscle cells are non striated because there is no regular arrangement of actin and myosin filaments. They are involuntary muscles.

Detailed explanation-3: -The biceps brachii is an example of a fusiform parallel muscle, and is responsible for flexing the forearm.

Detailed explanation-4: -Fusiform Muscles Sometimes, included in the parallel muscle group, these muscles are more spindle-shaped, with the muscle belly being wider than the origin and insertion. Examples are, Biceps Brachii and Psoas major.

Detailed explanation-5: -Fusiform muscle fibers run parallel to a muscle’s long axis. In this case, fiber length equals muscle length, and a fiber’s force generation transmits directly to the tendon. This arrangement facilitates rapid muscle shortening.
