Chap 13 Flashcards
______ matter on the outer surface of the cerebral hemisphere is ______.
Gray
cerebral cortex
4 cerebral lobes;
frontal
parietal
occipital
temporal
______ is the largest portion of brain
cerebrum
Frontal lobe -
voluntary motor function motivation aggression mood smell
Parietal lobe -
receive/evaluate general sensory info (not smell&hearing)
occipital lobe -
receive/integrate visual input
temporal lobe -
receive/evaluate smell & hearing
memory
anterior/inferior portion of temporal lobe -
“psychic cortex”
= abstract thought / judgement
dural partitions structure:
- falx cerebri (largest/longitudinal fissure)
- tentorium cerebelli (horizontal)
- falx cerebelli (between 2 hemispheres)
- olfactory nerve;
smell: sensory
- optic nerve;
vision: sensory
- oculomotor
4/6 of eyeball muscle: eye lid: motor & parasympathetic (pupil/lens)
- lavator palpebrae superioris
- uperior/onferior rectus muscle
- superior oblique
- trochlear;
1 eyeball muscle: somatic
- superior oblique
- trigeminal;
face, chewing, upper/lower jaw, teeth: sensory & motor
- abducens;
eye muscle:
- lateral rectus muscle
- facial;
taste (receptor of anterior 2/3 of tongue): sensory, motor & parasympathetic
- vestibulocochlear;
balance (vestibular) & hearing (cochlear): sensory
- glossopharyngeal;
posterior 1/3 of tongue for taste, salivary glands, tonsil, pharynx muscle, carotid arteries= blood pressure, Co2, O2, Ph level
sensory, motor & parasympathetic ganglia
- vagus;
pharynx, larynx, visera (heart, organ): sensory, motor & parasympathetic
- accessory;
neck (sternocleidomastoid), upper back (trapezius)
- hypoglossal;
3/4 of tongue muscle; speech, swallowing
diencephalon surrounds _____ ventricle of brain
third
______ fissure separates temporal lobe from rest of cerebrum
lateral
Cerebro Spinal Fluid (CSF) is found in;
- subarachnoid space
- ventricles of brain
- central canal of spinal cord
diencephalon components;
- thalamus
- hypothalamus
- subthalamus
cerebrospinal fluid (CSF) is produced in and flows through \_\_\_\_\_, and is reabsorbed within the\_\_\_\_\_ . P. 446
ventricles
meninges
anterior to the central sulcus is ______ gyrus; primary _____ cortex.
precentral
motor
posterior to the central sulcus is _____ gyrus;
primary ____ ____ cortex
post central
somatic sensory
fold on cerebrum that increases surface area;
gyrus (gyri: prural)
midbrain, pons, medula oblongata construct;
brainstem
diffuse system of several loosely packed nuclei throughout the length of the brain stem is;
reticular formation
reticular formation controls:
sleep-wake circle
state of alertness / consciousness
frontal lobe is important in;
- voluntary motor function
- motivation
- aggression
- smell
- mood
- decision making
- personality
rapid eye movement in sleep is a function of:
pons
nuclei involved in controlling motor function;
basal nuclei
function of cerebrospinal fluid
- protects brain from shock of rapid head movement
- provides nutrients to CNS tissues
hypothalamus functions;
most inferior of diencephalon
P.438
- heart rate, urine, digestive tract, blood vessel
- pituitary gland secretions, metabolism, ion concentration, sexual development & functions
- swallowing, shivering
- body temp
- hunger, thirst
- emotions; stress-related/psychosomatic illness, fear and rage
- sleep/wake cycle
- sexual development & behavior
thalamus form synapse in sensory pathways of;
- taste
- visual
- auditory
- pain
- mood
- actions of strong emotions (fear/rage)
Olive(s) are;
nuclei involved in functions of balance, coordination, modulation of sounds
