nervous system Flashcards
peripheral nervous system
nerves that carry signals INTO and OUT OF the central nervous system
central nervous system
-system that includes brain and spinal cord
-processes info and creates a response
action potential
nerve impulse
mutation in a hormone encoding gene results in
altered hormone function
hormone receptors are
proteins encoded into our genes
mutation in a receptor coding gene can
change the shape and efficacy of the receptor
genetic mutation can affect behavior by
affect morphology or physiology in ways that affect behavior (length of legs)
regulatory genes
genes that tell each other when where how much to express
central nervous where?
brain and spinal cord
peripheral nervous where?
nerves
sensory neurons
carry impulses from the sensory organs to the spinal cord and brain (peripheral)
interneurons
information from sensory neurons and sends commands to motor neurons to other interneurons (central- connects two systems)
motor neurons
carry impulses from the brain and spinal cord to muscles and glands (peripheral)
