CBSE Class 10 Science 2018 · Paper 31/1 · Question 4
- (a)Name one gustatory receptor and one olfactory receptor present in human beings.
- (b)Write a and b in the given flow chart of neuron through which information travels as an electrical impulse.
Answer
Taste buds are gustatory receptors, the nose lining holds olfactory receptors; a is the cell body and b the axon.
(a) Gustatory receptor (detects taste): the taste buds on the tongue. Olfactory receptor (detects smell): the olfactory receptors in the lining of the nose.
(b) a: cell body (cyton); b: axon.
Dendrite → cell body → axon → end point of neuron (nerve endings)
