Exam 4 Review Flashcards
Where is the pineal gland located
Just above the thalamus
Vagus nerve is associated with what nervous system
parasympathetic nervous system (PNS)
Gray matter of the cerebrum forms what layers
surface layer (cortex) over cerebrum and cerebellum
largest cranial nerve
V Trigenminal nerve
Cells found in the neocortex
small pyramidal cells, stellate cells, large pyramidal cells
most caudal part of the brainstem
medulla oblongata
which stract helps communication between the cerebrum and midbrain
projection tracts (ex, Corticospinal tracts)
An important center for autonomic control
hypothalamus
Which system is a bridge between emotions and autonomic responses
limbic system
no cranial nerves in what area of the brain
the cerebellum
here is the pons located
in the brainstem
why is 90% of cerebral cortex called the neocortex
it has relatively recent evolutionary origin
damage to what nerve may affect near vision accomodation
optic??
The regulator of most body functions
the hypothalamus??
Define Broca’s area
usually in left hemisphere, generates motor program for the muscles of the larynx, tongue, cheeks, and lips for speaking and for hands when signing
function of the occipital lobe
primary visual center of brain
what separates the cerebral hemispheres
the longitudinal fissure
the diencephalon gives rise to what structures
the thalamus, hypothalamus, epithalamus
Do sympathetic affects last longer or shorter than parasympathetic and why
they are reabsorbed in the bloodstream before finally degrading in the liver, so they last mines instead of sconds
functions of superior colliculi
visual attention, tracking moving objects, and some reflexes
Function of frontal lobe
voluntary motor functions, motivation, foresight, planning, memory, mood, emotion, social judgement, and aggression
what’s found in the limbic system
hippocampus, amygdala
fibers of the vagus nerve end where
the cardiac plexus
destruction of the amygdala affects what
emotional memories (and decision making?)
