Front

What surrounds individual muscle fibers?

Back

The endomysium surrounds individual muscle fibers.

Front

What does smooth muscle lack?

Front

What is the primary function of skeletal muscle?

Back

Front

What is the role of calcium in muscle contraction?

Back

Calcium ions are essential for muscle contraction as they trigger the interaction between actin and myosin.

Front

What is the epimysium?

Back

The epimysium is a connective tissue that surrounds the entire muscle.
