Physiology of Muscles

Front

What are the three types of muscular tissue?

Back

Skeletal muscle, cardiac muscle, smooth muscle.

Front

How is ATP formed? (Name of the process)

Back

Cellular Respiration (Oxidative phosphorylation)

Front

Which muscles are involuntary?

Back

Smooth and cardiac muscles.

Front

What do all muscle types require for contraction?

Back

Calcium ions (Ca2+).

Front

____________ and _____ produce muscle contraction.

Back

Actin and myosin.

Front

What is the primary function of skeletal muscle?

Back

To facilitate voluntary movement of the body.

Front

What is the role of cardiac muscle?

Back

To pump blood throughout the body involuntarily.

Front

What is smooth muscle responsible for?

Back

Involuntary movements in internal organs.

Front

What is the sliding filament theory?

Back

A theory that explains how muscles contract by the sliding of actin and myosin filaments over each other.

Front

What is the role of calcium ions in muscle contraction?

Back

Calcium ions bind to troponin, causing a conformational change that allows myosin to bind to actin.
