Front

What are flexors?

Back

Muscles that decrease the angle between body parts, typically involved in bending movements.

Front

What does the term 'superficial' mean in anatomy?

Back

Refers to structures that are closer to the surface of the body.

Front

What is cross bridge formation?

Back

The process where the myosin head binds to the actin molecule during muscle contraction.

Front

What must occur first before a muscle can contract?

Back

An action potential must be sent through neurons in the nervous system.

Front

How many attachments must a muscle have according to Muscle Rule 1?

Back

At least two attachments.

Front

What are extensors?

Back

Muscles that increase the angle between body parts, typically involved in straightening movements.

Front

Define the term 'deep' in anatomical context.

Back

Refers to structures that are further away from the surface of the body.

Front

What is the power stroke in muscle contraction?

Back

The movement of the myosin head pulling the actin filament during muscle contraction.

Front

What is synaptic transmission?

Back

The process of transmitting signals between neurons at the synapse.

Front

What is excitation-contraction coupling?

Back

The physiological process of converting an electrical stimulus to a mechanical response in muscle fibers.
