Muscle Contractions Flashcards
Axon terminal
Axons divide and end in an axon terminal
Motor neuron
Nerve cells that activate skeletal muscle cells
Action potentional
Message from nerve
Motor end plate
Region of sarcolemma facing neuromuscular junction
Acetylcholine
Neurotransmitter involved in muscle contraction
Neurotransmitter
Released by first cell to communicate with second cell
Synaptic cleft
Gap between two cells
Synapse
Region where communication occurs between 2 neurons or neuron and target
Neuromuscular junction
Where the muscular and nervous system combine to control muscles
Synaptic vesicles
Sac-like containers that have neurotransmitters
Depolarization
The inside is positive compared to the outside
Troponin
A protein that binds with actin
Tropomyosin
A protein that’s bound to actin
