What is the endomysium?

Back

The endomysium is a thin layer of connective tissue that surrounds each individual muscle fiber, providing support and insulation.

Front

What are myofilaments made up of?

Back

Myofilaments are made up of two types of proteins known as Actin and Myosin.

Front

What is the sarcolemma?

Back

The sarcolemma is the cell membrane of a muscle fiber, which plays a crucial role in muscle contraction.

Front

What is a fascicle?

Back

A fascicle is a bundle of muscle fibers surrounded by perimysium, which is a type of connective tissue.

Front

What is the function of myofibrils?

Back

Myofibrils are the contractile units of muscle fibers, responsible for muscle contraction.

Front

What is the role of mitochondria in muscle cells?

Back

Mitochondria provide energy for muscle contractions through aerobic respiration.

Front

What is the sarcoplasm?

Back

Sarcoplasm is the cytoplasm of a muscle cell, containing myofibrils, organelles, and other substances necessary for muscle function.

Front

What is the epimysium?

Back

The epimysium is a layer of connective tissue that surrounds the entire muscle, providing structure and support.

Front

What are the two types of muscle fibers?

Back

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