3 parts of the brain
cerebrum, cerebellum, brain stem
cerebrum?
controls the body. think, imagine, plan, make rational decisions.
cerebellum?
underneath the cerebrum. posture, coordination, balance, movement.
brain stem
base of the brain. involuntary actions. extremely vital to body.
parts of the nervous system?
central nervous system, peripheral nervous system.
cns consists of?
brain and spinal cord
pns consists of
, nerves that extend from the spinal cord to extremities.
dendites?
communication between neurons
axon
carries messages to and from the cell body
cell body
receives and send smassages
types of neurons
sensory neurons, relay neurons, motor neurons
synapse?
gap between 2 neurons.
neuroplasticity
where nerve cells make new connections to learn new things. rewiring our brain.
homeostasis
maintenance of a constant internal enviroment.
stimulus response model?
stimulus-receptor-control cnetre-effector-response
reflex actions
cns sends electrical signals via the spinal cord to the muscles.
endocrine system + hormones
production of hormones. Hormones aree protein secretes directly into the bloodstream.
3 g’s
gulcagon, glycogen, glucose
gulcagon?
released when blood glucose is low. hormone formed in the pancreas. promotes the breakdown of glycogen to glucose in the liver.
glucose
sugar, energy source
what does the left hemisphere do?
