What is a cramp?
This is the molecule that powers muscle contractions.
What is ATP?
This is only muscle type under voluntary control.
What is skeletal muscle?
The specialized membrane of muscle cells.
What is a sarcolemma?
This the fluid filled gap between the end of the motor neuron and the sarcolemma.
What is the synaptic cleft?
This condition is caused by tiny tears in the muscle and bone tissue in the shins.
What are shin splints?
This is the protein that does the pulling in muscle contraction.
This is the only nonstriated muscle.
What is smooth muscle?

What is calcium?
These are the two points where skeletal muscle connect to bone.
What are the origin and insertion?
The units of myofibrils that do the work of contracting.
What are sarcomeres?
This the name of the part of the motor neuron that extends towards the sarcolemma to release the neurotransmitters?
