Question

(i) Define receptor and state their location in our body. Mention any two receptors present in our forebrain and their functions.
(ii) How do nerve impulses travel in our body?

Answer 1

(i) Specialised tips of some nerve cells which receive information from the surroundings.
Location: Sense organs
Gustatory receptor: detect a taste
Olfactory receptor: detect a smell
(ii) The information acquired at the end of the dendritic tip of a nerve cell sets off a chemical reaction that creates an electrical impulse, which travels to the cell body, then along the axon to its end, releases some chemicals, across the synapses.
