Question

arrangement of fascicles
skeletal muscles consist of fascicles (refer to figure 6.1), but fascicle (1. ) vary, producing muscles with different structures and functional properties. next, lets look at the most common (2. ) of fascicle arrangement: circular, convergent, fusiform, parallel, multipennate, bipennate, and unipennate.
in a circular pattern, the fascicles are arranged in (3. ) rings (figure 6.15a). circular muscles are typically found surrounding external body openings which they close by contracting, creating a valve. a general term for such muscles is (4. ) (\squeezers\). examples are the orbicularis muscles surrounding the eyes and mouth.
in a convergent muscle, the fascicles converge toward a single (5. ) tendon. a convergent muscle is triangular or fan - shaped, such as the pectoralis major muscle of the anterior thorax (figure 6.15b).

Explanation:

1. "Patterns" makes sense as fascicle (1) patterns vary.
2. "Patterns" is correct for the most common (2) of fascicle arrangement.
3. "Concentric" describes the rings in circular - pattern fascicle arrangement.
4. "Sphincters" is the general term for muscles that close body openings.
5. "Insertion" is what fascicles converge toward in a convergent muscle.

Answer:

2. patterns
