Question

muscles with which muscle fascicle arrangement blend into a tendon that runs through the central region of the muscle for its whole length?

a.) pennate
b.) convergent
c.) parallel
d.) circular

Explanation:

Analyze the structural description of the muscle

The question describes a muscle where fascicles blend into a central tendon running through the entire length of the muscle. This feather-like pattern is characteristic of a pennate arrangement (specifically bipennate or multipennate, where fibers attach obliquely to a central tendon).

Evaluate the given options

• Pennate: Fascicles attach obliquely to a central tendon running through the muscle. This matches the description.
• Convergent: Fascicles extend from a broad origin and converge toward a single, narrow tendon.
• Parallel: Fascicles run parallel to the long axis of the muscle.
• Circular: Fascicles are arranged in concentric rings around an opening.

Answer:

• a.) Pennate (Correct answer)
• b.) Convergent
• c.) Parallel
• d.) Circular
