conscious and unconscious response (neurons and types)

Question 1

neurons are cells within the nervous system that transmits messages to and from the brain (each neuron have different functions)
they are the building blocks of the nervous system with over 200 types of them
the main 3 neurons being sensory neuron, motor neuron and interneurons.

Question 2

WHAT ARE SENSORY NEURONS

Answer 2

sensory neurons transmits sensory information from the body to the brain.
via afferent pathways (afferent meaning towards) -> the brain

Question 3

WHAT ARE MOTOR NEURONS?

Answer 3

motor neurons transmits motor information from the brain to the body.
via efferent pathways (efferent meaning away) -> the brain

Question 4

WHAT ARE INTERNEURONS?

Answer 4

interneurons transmits information between sensory and motor neurons
most numerous neurons in the brain
not found in the PNS
