Q

What is Skeletal Muscle?

A

‘voluntary muscle’ Muscles that you think about contracting and then the nervous system tells them to do so. Anchored to bone via tendons and is designed to generate skeletal movement

Q

How are muscles and the nervous system related?

A

The movement of muscles is coordinated and controlled by the nervous system, that sends a message to the muscles ‘telling’ it to move

Q

What does the Muscle Spindle Stretch Receptor do?

A

When a muscle stretches, the muscle spindle
that sends a signal to the spinal cord which in turn sends a message to the muscle to contract and resist
the stretch.

Q

What is a spinal cord reflex arc?

A

A neural pathway that controls a reflex, where sensory neurons do not go all the way to the brain, only to the spinal cord
