parts of the brain Flashcards
thin layer around brain and spinal cord
cerebrospinal fluid
protects basic movements and is the nourishment of cells
cerebrospinal fluid
unconscious function control; breathing, heartbeat, reflexes
medulla
movement, sleep, arousal, sleep paralysis
pons
motor coordination, balance, walking in a straight line
cerebellum
groups of fibers that carry stimulation related to sleep and arousal through brain stem
reticular formation (RAS)
compass, all sensory info (except smell) passes through to cerebral cortex, point direction of sensory info to the right part of the brain
thalamus
-respond to a decision, unconscious, cant control
-hormones through blood stream
-pituitary gland
- 4 f’s
hypothalamus “to-do”
memory, short term memory convert to long term memory
hippocampus “hippos remember too”
emotion; fear, anger, aggression
amygdala
smell
olfactory bulb
sensing, thinking, learning, emotion, voluntary movement
corpus callosum
connection between the two hemispheres
corpus callosum
planning, prepping, personality, processing emotions, speech and language
frontal lobe
fine motor skills
motor cortex
production of speech
brocas area
pain perception, spatial processing, sensation
parietal lobe
skin sensation; pain and temperature
somatosensory cortex
recognizes sounds, storing memories, linking memories to senses
temporal lobe
language comprehension, speech
wernickes area
sight, perception
occipital lobe
hormone release
pituitary gland
the largest, most evolved part of the brain
cerebrum
most primitive and basic part of the brain
brainstem
how is the pons like a bridge?
linked to waking up and sleeping
four main lobes of the cerebrum
frontal, parietal, temporal, occipital
four parts of the limbic system
hypothalamus, amygdala, hippocampus, olfactory bulbs
what could happen if the hypothalamus stopped working?
there would be no reaction to a stimulus
why is the hypothalamus important to the endocrine system?
connects to the pituitary gland
three parts of the brain stem
pons, medulla, spinal cord (brain stem)
four important functions that are controlled by the brain stem
fight, flight, feed, fornication
what cortex is in the frontal lobe?
motor
what cortex is in the parietal lobe?
somatosensory
