neurons

Question 1

difference between sensory neurons and motor neurons

Answer 1

Sensory neurons carry messages from sense organs to the brain or spinal cord.
Motor neurons carry messages from the brain or spinal cord to muscles or glands.

Question 2

difference between reflex reactions and conscious decisions

Answer 2

Reflex reactions happen automatically and quickly without thinking. They follow the reflex arc, where sensory neurons send a message to the spinal cord, which immediately sends a response back through motor neurons.
Conscious decisions involve the brain thinking and deciding before sending a message to act, so they take longer than reflex reactions.
