The Nervous System Lecture Flashcards
What is the primary function
to coordinate all the activities that the body does
Whats one way the brain helps control
homeostasis (helps us respond to stuff that is happening in and out)
what are the 2 main parts
1) central nervous system
2) Peripheral nervous system
where is the brain found in
the skull / crarium
what are the important structures
- brain stem
- cerebrum
- cerebellum
- diencephalon
T or F: the cerebrum is the largest section
true
what are the 2 sections of the cerebrum
right and left heminsphere
what are the 4 lobes
- frontal (blue)
- parietal (yellow)
- temporal (green)
- occipital (pink)
parietal
connects with your sensory info
(sensory vs. moter)
frontal
intellectual - thinking
temporal
auto-ray info from the ears
occipital
gets info from the eyes
cerebellum
responsible for muscle coordination, balance, posture
diencephalon (where found)
between the cerebrum and mid brain
diencephalon (the 2 structures)
thalomus and hypothoinus
motor refers
movement
sensorary
what you collect
what are some things you dont have control over
- temp
- eyes dilate
- emotions
brain stem
- mid brain
- pans
- medulla
mid brain
located on top of the brain & responsible for eye and hearing reflex
pans
mid brain and medulla (located) & responsible fore chewing, tasting, Silvia
medulla
connects the spinal cord to the brain & regulates heart / blood vessels
cervival
nerves that connect to the upper body (arms + fingers)
thoracic
nerves that go through chest & stomach
lumber
controls lower part
sacrum
lower part (legs, anus, thighs, genitals)
reflex hammer
medical instrument used to test reflexes
