Neuromuscular functions

100

What is the working part of the muscle fiber called?

Sarcomere

200

What is the long thin fibers that connect the neural cell body and the muscle fibers?

Axon

300

This chemical within a cell acts as a fuel or energy to cause something to happen. What is this fuel/energy called?

Adenosine Triphosphate (ATP)

400

This synaptic cleft (gap) between the muscle fiber and the axon terminal is filled with fluid. What neurotransmitter moves across this gap?

Acetylcholine (ACh)

500

During muscle stimulation, the cell moves 2 chemicals in and out of the cell membrane. What 2 chemicals are they?

Sodium (Na) and Potassium (K)

500

What is a temporary change in the electrical potential across a cell's membrane that travels along the axon to transmit signals?

Action potential

Directional movement

100

This is movement toward the body.

Adduction

200

This movement is rotational and makes a circle.

Circumduction

300

This movement causes the foot to move inward.

Medial rotation

400

This movement points the toes downward.

Plantar flexion

500

This movement is away from the body.

Abduction
