Answer 1

Answer:

Answer 2

Definitions

Explanation:

Receptor is an organ or cell that is able to respond to external stimulus like light, heat, or touch, and transmit the signal to a sensory nerve.

Synapse or a neuronal junction is the site of transmission of electric nerve impulses between two neurons, or between a neuron and an effector.

A hormone is signaling molecules produced by glands and transported by the circulatory system to target distant organs to regulate physiology and behavior.

A neuron is a nerve cell that carries electrical impulses.

Impulse is the signal that travels along the length of a nerve fiber and ends in the release of neurotransmitters.

A stimulus is something that causes a reaction. The reaction can be physical or chemical.

An effector is an organ or cell that acts in response to a stimulus.
