neurons Flashcards
(2 cards)
difference between sensory neurons and motor neurons
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.
difference between reflex reactions and conscious decisions
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.
