Unit 3, Lecture 2

Front

What is a fascicle?

Back

A fascicle is a bundle of muscle fibers.

Front

What is a muscle fiber?

Back

A muscle fiber is a single muscle cell that contracts to produce force.

Front

What is the endomysium?

Back

The endomysium is a connective tissue sheath that surrounds each individual muscle fiber.

Front

What is the perimysium?

Back

The perimysium is a connective tissue sheath that envelops each bundle of muscle fibers (fascicle).

Front

What is the epimysium?

Back

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

Front

What is the sarcolemma?

Back

The sarcolemma is the cell membrane of a muscle fiber.

Front

What is the function of muscle fibers?

Back

Muscle fibers contract to facilitate movement and maintain posture.

Front

What is the role of connective tissue in muscles?

Back

Connective tissue provides support, structure, and protection to muscle fibers and facilitates the transmission of force.

Front

How do fascicles contribute to muscle function?

Back

Fascicles allow for the organization of muscle fibers, enabling efficient contraction and force generation.

Front

What is the relationship between muscle fibers and fascicles?

Back

Muscle fibers are grouped together to form fascicles, which are then grouped to form the whole muscle.
