What excites skeletal muscles and inhibits cardiac muscle?
Excitation
* Skeletal muscle: Acetylcholine (ACh) released from motor neurons
* Cardiac muscle: Calcium ions (Ca2+) released from the sarcoplasmic reticulum
Inhibition
* Skeletal muscle: None
* Cardiac muscle: Hyperpolarization of the cell membrane, which can be caused by a number of factors, including the release of acetylcholine from parasympathetic nerves
