Muscular System Anatomy

Front

What type of muscles are skeletal muscles?

Back

Skeletal muscles are voluntary muscles.

Front

What is the thick filament in muscle fibers composed of?

Back

The thick filament is composed of Myosin.

Front

What is the thin filament in muscle fibers composed of?

Back

The thin filament is composed of Actin.

Front

What is the gap between the nerve cell and sarcolemma called?

Back

The gap is called the Synaptic cleft.

Front

What does the epimysium cover?

Back

The epimysium covers the entire muscle.

Front

What is the primary function of skeletal muscles?

Back

The primary function of skeletal muscles is to facilitate movement by contracting.

Front

What is the role of myosin in muscle contraction?

Back

Myosin interacts with actin to produce muscle contraction.

Front

What is the neuromuscular junction?

Back

The neuromuscular junction is the synapse between a motor neuron and a skeletal muscle fiber.

Front

What is the function of the sarcolemma?

Back

The sarcolemma is the cell membrane of a muscle fiber that conducts electrical impulses.

Front

What are the two main types of muscle fibers?

Back

The two main types of muscle fibers are Type I (slow-twitch) and Type II (fast-twitch).
