Synapse, Biology

SYNAPSE -

The point where 2 neurons combine is synapse.

It is of 2 types -

(i) Axosomic (between axon & cyton)

(ii) Axodendric (between axon & dendron)

Axon is termed as pre synaptic terminal while dendron is termed as post synaptic terminal.

Synapse name is given by Sir Charles Sherington.

1. Chemical             2. Electrical
