36 Cards in this Set

  • Front
  • Back
(memory and learning)
possession of facts
(memory and learning)
acquisition of knowledge
(memory and learning)
retention of that knowledge
(memory and learning)
the ability to learn, retain and process knowledge
(types of memory)
short term
short duration, mostly electrical in functions. neurons connected in a circuit and continue to stimulate each other.
(types of memory)
long term
long duration, structural in function. new synapses are formed allowing memory.
Basal nuclei (ganglia)
masses of gray matter located deep w/in hemispheres.
F(x)-relay messages from cortex to brain stem+cord, produce the NT dopamine.
Parkinson's disease
is a decline in dopamine due to death of basal nuclei cells. causes tremors then paralysis. cause believed to be chemical and traumatic damage to brain. ex..designer drugs, boxing
The Diencephalon
surrounds third ventricle: almost all gray matter
(regions of the diencephalon)
f(x)-recieves, filters, +directs all afferent sensory impulses to correct region of cortex.
(regions of the diencephalon)
f(x)- homeostasis
(regions of the diencephalon)
(regions of the diencephalon)
f(x)-suspends pituitary gland
(regions of the diencephalon)
hypophysis(pituitary gland)
F(x)-hormone production
Hypothalamus regulates:(9)
heart rate, blood pressure, body temp,h20 balance, hunger, digestion, sleep, hypophysis secretions, emotion
pineal gland(body)
f(x)-produce + secrete melatonin
choroid plexus
f(x)-produce + secrete CSF
(Regions of the Braind Stem)
myelinated fibers w/some gray matter
f(x)-connects brain stem w/ superior brain and relays messages
(Regions of the Braind Stem)
cerebral aqueduct
f(x)-connects 3rd and 4th ventricle
(Regions of the Braind Stem)
cerebral peduncles
f(x)nerve tracts that are the main motor pathways between cerebrum and rest of nervous system
(Regions of the Braind Stem)
corpora quadrigemina
f(x)-relay centers for visual and hearing reflexes
(Regions of the Braind Stem)
red nucleus
f(X)-provides reflexes to maintain posture works w/cerebellum
(Regions of the Braind Stem)
f(x)-fibers relay impulses from cord to cerebrum
(Regions of the Braind Stem)
medulla oblongata
f(x)-fibers relay impulses from cord to cerebrum
Basal nuclei in M.O regulate: (3)
a. heart rate
b. blood pressure
c. respiration
reticular formation
network of fibers(axons) and gray matter(throughout brain stem)
what happens if you damage the reticular formation?
causes a coma or persistent vegetative state if damaged.
what causes insomnia?
intense cerebral activity stimulates the reticular formation causing____
(types of sleep)
slow wave (non-Rem)
decrease activity of reticular formation and cortex causes restful, dreamless sleep w/ dec. BP, hear and respiration
(types of sleep)
rapids eye movement (REM)
regions of cortex active. dreams w/ irreg. Inc. BP, heart and respiration
functions of the cerebellum:3
balance, coordination and posture
Regions of the cerebellum (3)
1.cerebellar cortex
2. white matter
nerve tracts that communicate w/ other parts of CNS
mixed nerve hierarchy
peripheral nerve>fascicle>fiber/axon
CT hierarchy overview
Cranial nerves (12):
