which of the following is a pattern of muscle fascicle arrangement where the fascicles are arranged concentrically around a body or organ opening?
convergent
circular
pennate
parallel

Explanation:

Muscle fascicle arrangements:

• Convergent: Fascicles converge to a single tendon.
• Circular: Fascicles arranged concentrically around an opening (like orbicularis oris around mouth).
• Pennate: Fascicles attach obliquely to a tendon (unipennate, bipennate, multipennate).
• Parallel: Fascicles run parallel to muscle long axis (e.g., sartorius).

B. Circular
