Neuromuscular Junction

What generates a nerve impulse on the post-synaptic membrane? 

• Calcium binding with a receptor site
• Potassium leaking into the post-synaptic membrane 
• Neurotransmitter binding with receptor sites
• Neurotransmitter being removed from the synapse

This is the electrical charge that travels down an axon when a neuron is firing

• Resting Potential
• Action Potential
• Threshold
• Refractory Period

One neuron and all the skeletal muscle cells it stimulates is the ____ ___.

• Neurotransmitter

• Neuromuscular junction

• Motor unit

• Synaptic cleft

In response to action potentials arriving along the transverse tubules, the sarcoplasmic reticulum releases

• acetylcholine.
• sodium ions.
• potassium ions.
• calcium ions.

The area between the pre-synaptic cell and the post-synaptic cell is termed the synaptic cleft.

• True
• False

• connecting within the brain to help you make a decision

• sending a message toward your brain from a pain receptor in your skin

• all of these
