nervous system Flashcards
What are the two parts of the nervous system?
PNS (peripheral nervous system) and CNS (central nervous system)
What are the functions of the PNS?
carries out actions sent from brains, relays info from the brain
What makes structures make up the peripheral nervous system?
made up of nerves
What are the functions of the CNS?
control center, sends motor commands from the brain to the body, controls involuntary movements
What structures make up the CNS?
the brain and the spinal cord
What are the three parts of the brain?
the cerebrum, cerebellum, and brainstem
What makes up the cerebrum?
frontal lobe, parietal lobe, temporal lobe, and occipital lobe
What makes up the cerebellum?
the cerebellum
What makes up the brainstem?
pons and medulla oblongata
Where is the cerebellum and what is it’s function?
underneath the occipital lobe, muscle coordination, movement, and balance
Where is the brainstem and what is it’s function?
bottom of brain, communication w/cerebrum and cerebellum
Where is the cerebrum and what is it’s function?
function and location of the lobes
Where is the frontal lobe and what is it’s function?
front of the brain, reasoning, happiness, problem solving, and speech
Where is the parietal lobe and what is it’s function?
side of brain: taste, bodily sensations
Where is the motor cortex and what is it’s function?
back of the frontal lobe: facial movement
Where is the occipital lobe and what is it’s function?
back of brain on top of occipital: vision
Where is the temporal lobe and what is it’s function?
on the side of the brain: lang. understanding, hearing
Where is the sensory cortex and what is it’s function?
the front part of the parietal lobe: bodily sensations
Where is the pons and what is it’s function?
top part of the brain stem: breathing
Where is the medulla oblongata and what is it’s function?
bottom of the brain stem: breathing, blood pressure regulation
Where is the Thalamus and what is it’s function?
near the center of the brain: relay station between senses and processing
Where is the Hypothalamus and what is it’s function?
It is in the center below the thalamus: thirst, hunger, sleeping, waking, and homeostasis
Where is the hippocampus and what is it’s function?
Above the pons: long term memory
Where is the amygdala and what is it’s function?
above the pituitary gland: happiness and stress
