Question

Assertion (A): The aggregates of the cell bodies or perikaryons of neurons form the synapse.

Reason (R): Ganglia are the structures from which the nerve fibres may arise or enter into, whereas the synapse connects two neurons with a small gap in between.

1. A is True and R is False.
2. A is False and R is True.
3. Both A and R are True.
4. Both A and R are False.

Answer 1

(2)

Explanation:

Aggregates of neuronal cell bodies, or perikarya, form ganglia, not synapses. Therefore, the Assertion (A) is false.

Ganglia are collections of neuron cell bodies associated with nerve fibres, whereas a synapse is the junction between two neurons separated by a very small gap called the synaptic cleft. Therefore, the Reason (R) is true.

Hence, A is false and R is true.
