Question

A neuron cell body reaches threshold and depolarizes. The depolarization propagates down the length of the ______, is chemically transmitted across the ______, and directly affects the electrical potential in the ______ of the successive neuron.

Answer 1

Axon.

Synapse

Dentrite and cell body.

Step-by-step explanation:

AXON is the transmission conduit for action potential through saltatory conduction at the nodes of ranvier.

Synapse refers to the gap between adjacent nuerones and the entire components of that particular gap.

Denrites which originated from the cell.body received the transmitted signals from.the axon,and transmits this for response at effectors:muscle and glands.
