Question
What is produced by enteric nerves for muscle contraction something..
A) Nitric oxide
B) Histamine
C) Norepinephrine
D) Substance P
Solution
The enteric nervous system, which is a part of the autonomic nervous system and is found in the gastrointestinal tract, produces several neurotransmitters for various functions including muscle contraction.
A) Nitric oxide: This is a neurotransmitter that is produced by the enteric nerves. It is involved in the relaxation of smooth muscle, which is a type of muscle found in the gut.
B) Histamine: This is not produced by the enteric nerves. It is a compound that is involved in local immune responses and also acts as a neurotransmitter.
C) Norepinephrine: This is a neurotransmitter that is produced by the sympathetic nervous system, not the enteric nervous system. It is involved in the fight or flight response.
D) Substance P: This is a neuropeptide that is produced by the enteric nerves. It is involved in pain perception and also plays a role in the contraction of smooth muscle in the gut.
So, the enteric nerves produce both Nitric oxide and Substance P for muscle contraction and relaxation in the gut.
