The Brain Flashcards
brain stem
regulates visceral (autonomic) functions
medulla oblongata
heart beat, respiration, blood pressure
pons
relay of sensory info
midbrain
visual reflexes and eye movements
cerebellum
balance and coordination
diencephalon is made up of
thalamus, hypothalamus
thalamus
relay station
hypothalamus
hormones, heart rate, blood pressure, body temp, hunger (homeostasis)
pituitary
control endocrine system by altering hormone levels
limbic system is composed of
hypothalamus, hippocampus, amygdala
function of limbic system
emotion and emotional memories
hippocampus
memory
amygdala
▫stores memories associated with emotional events
▫fear
cerebrum
controls higher mental function
fissure
deep groove
longitudinal fissure
separates right and left hemisphere
transverse fissure
separates cerebrum from cerebellum
lateral fissure
separates temporal lobe from formal and parietal
corpus collosum
allows for communication between the two hemispheres
frontal lobe
higher order thinking, planning, problem solving
motor cortex
movement
sensory cortex
sensations
parietal lobe
perception, math, spelling
occipital lobe
vision
temporal lobe
hearing, language, memory
optic chiasma
region of the brain where optic nerves cross over eachother
venteicles
fluid filled cavities containing CSF
how many ventricles are there
4
episodic memory
remembering personal experiences
semantic memory
facts
procedural memory
skills that are performed automatically
working memory
temporary storage for complex cognitive tasks (language, learning, reasoning)
olfactory nerve
sense of smell
optic nerves
vision
ocular motor nerve
controls movement of the eyeball
trochlear nerve
control muscles around the eye
trigeminal nerve
responsible for sensation if the face
abducens
controls movement of muscles around the eye
facial nerve
controls most of the movement in the face
vestibulocochlear neve
hearing and balance
glossopharyngeal nerve
controls pharynx and tongue (swallowing, speech)
vagus nerve
controls all organs in thoracic and abdominal cavities
accessory nerve
controls shoulder muscles
hypoglossal nerve
controls tongue
12 cranial nerves in order
- olfactory
- optic
- ocular motor
- trochlear
- trigeminal
- abducens
- facial
- vestibulocochlear
- glossopharyngeal
- vagus
- accessory
- hypoglossal
average size of a male brain
1500g
what determines intelligence
number of synapses
four regions of the brain
▫cerebrum
▫brain stem
▫cerebellum
▫diencephalon
what can be seen when the cerebellum is cute
arbor vitae
outer most region of the cerebrum
cerebral cortex
