The Peripheral Nervous System

Question 1 • Biology - SC3209 IC

What is the role of sensory neurons in the breakdown of food?

Answer
A
Sensory neurons digest carbohydrates in the digestive tract.
B
Sensory neurons cause chewing of food in the mouth.
C
Sensory neurons release hormones so that the brain can cause the food to be moved and digested in the digestive tract.
D
Sensory neurons sense the presence of food and relay the information to the brain so that food can be moved and digested in the digestive tract.

Explanation

Sensory neurons detect stimuli, such as the presence of food, and carry information from the body to the brain. The brain can then coordinate responses that help move food through the digestive tract and digest it. Sensory neurons do not digest carbohydrates or release hormones, so D, “sense the presence of food and relay the information to the brain,” is correct.
