Week 1 Flashcards
PNS
peripheral nervous system
Everything else in the body!
CNS
Central Nervous System
Brain and spinal cord
what does the PNS and CNS regulate and control?
Body movement, HR, RR, BP
Detect sensation and facilitate thought, emotion and language
what does the Primary motor cortex do
voluntary movement
what does the primary somatosensory cortex do?
sensation
what does the broca do
motor speech
what does the wernicke do
understand speech
what does the primary visual cortex do
vision
what does the primary auditory cortex do
hearing
what does the frontal eye fields do
eye movement
Neuroplasticity
pruning of connection
adding connections
adaptable
Where can cells not regenerate?
brain and spinal cord
parts of the spinal cord
upper motor neurons (UMN)
Lower motor neurons (LMN)
What does the spinal cord do?
connects the brain to the PNS
PNS function
transmits motor info from the brain to the muscles
tells CNS about change
responds to brain’s signal
regulates body function (keeps you alive)
PNS nerves
Afferent nerves
efferent nerves
Afferent nerves
goes up the PNS (sensation)
Efferent nerves
goes down the PNS (motor)
controls muscle movement
four major regions of brain
cerebrum
diencephalon
brainstem
cerebellum
cerebrum
higher level thinking (grey matter (cell body)/white matter (myelin axons))
Cerebral cortex
corus callosum
limbic system
The brain as a whole
Cerebral cortex
grey part
cell bodies
corus callosum
connects both sides of the brain
limbic system
entire inside brain
emotions and memories in every part of the brain
touches every part of the brain
contains portions of all 4 anatomical lobes
large role in emotion and memory
diencephalon
through brain
thalamus/hypothalamus (relay center)
brainstem and the three major parts
contains life functions
midbrain, pons, medulla
