Answer:
they are Na+, K+ and Ca2+ ion channels.
Explanation:
Ionotropic acetylcholine receptors are also called nicotinic acetylcholine receptors because beside acetylcholine (Ch) they respond to nicotine. These receptors are primary receptors in muscle for motor nerve-muscle communication that controls muscle contraction.
Two molecules of ACh are required for receptor to open. Since the receptors are linked to ion channels, the channels open. Opening of the channel allows positively charged ions to move across it: sodium enters the cell and potassium exits.
<span>One reflex reaction to maintaining homeostasis in the body is shivering. In response to cold temperatures, the muscular system moves our muscles quickly to warm them up as a rapid, short term solution for homeostasis. Another example is the withdrawal reflex, which occurs as a response to pain. Pain receptors activated by the painful stimulus activate the motor neurons in the body, which in turn contract muscles to move parts of your body away from the pain.</span>
