Interneuron, motor neuron and glial cells
Positively charged proteins
The inside of the axon is briefly more positive than the outside of the axon.
Vesicles containing neurotransmitters fuse with the cell membrane
Potassium channels open
The sodium/potassium pump begins actively transporting ions
Nerve messages are inhibited
Nodes of Ranvier
Potassium channel proteins
The depolarization of the sarcolemma.
An action potential to fire down the axon.
Calcium channels in the cell membrane to open.
Calcium ions to be pumped into the sarcoplasmic reticulum.
Also known as efferent neurons
Carry messages to the CNS
Connect to muscles
Are found in different nerves than motor neurons
Cholinesterase breaks down the acetylcholine.
There is a limited amount of acetylcholine.
Once the calcium in the cell is used up, the muscle relaxes.
Other molecules can block the acetylcholine receptors.
