Chapter 13 Flashcards
What does damage to the brain cell usually result in
death
A cluster of gray matter containing cell bodies in the CNS are called what
nuclei
Decussation
crossing over of the pyramids in the medula
The left side of the brain controls which side of the body
RIght
The right side of the brain controls what side of the body
Left
The medulla oblongata contains what
nuclei that regulate heart and blood vessel diameter
Pyramids of the medulla contain descending what
motor (muscle) nerve tracts (in other words they move from the brain to the body)
What would damage to the pontine nuclei probably affect
respiration
the pons and medulla oblangata control respiration
Where are the superior and inferior coliculi located
the tectum (roof) of the mid brain
The superior coliculi contain what
the visual reflexes
The inferior coliculi contain what
auditory reflexes
What would a lesion to the cerebral reflexes affect
movement
What are the red nuclei involved in
unconscious regulation and coordination of motor activities
Whats the reticular formation composed of
Nuclei scattered throughout the brain stem
Cerebellar (not cerebral) pednucles are what
nerve tracts between the cerebellum and the rest of the brain
What lobe of the cerebellum is involved with balance and eye movement
the flocculonodular lobe
What does the lateral cerebellar hemisphere function to control
smooth, flowing movement
The cerebellum in general functions to
coordinate control of voluntary movements, maintain muscle tone, control skeletal muscles and balance, control posture, locomotion, and fine motor coordination
What is the name of the stalk that connects the hypothalamus to the pituitary gland
the infundibulum
What does the epithalimus contain
the habenular nuclei and pineal body
Why is the thalamus like a sensory filter
almost all sensory information from the spinal cord and brain steam goes through the thalalmus before entering the cerebrum (not cerebellum)
The mammillary bodies are involved in what
emotional response to odor
Whats the major control center for the autonomic nervous system and endocrine system
the hypothalamus
The descending order of structures
midbrain
pons
medulla
spinal cord
Which body is involved with the onset of puberty
the pineal body
What increases the surface area of the cerebrum
cerebral gyri
The central sulculus seperates what
the frontal and parietal lobes
What type of matter is the cortex of the cerebrum
gray matter
What are the tracts of white matter that connect the left and right cerebral hemisphere
commissural fibers
What the large C-shaped mass that connects 2 hemispheres
corpus callosum
The cerebral medulla consists of what
many nerve tracts of white matter beneath the cerberal cortex
The corpus striatum is composed of
the lentiform and caudate nuclei
The limbic system is associated with what
basic survival instincts of nutrition, memory, and reproduction
The limbic system contains what
cingulate gyrus of the of the cerebral cortex
denate gyrus of the hippocampus
olfactory cortex
The cerebral aquaduct connects what
the 3rd and 4th ventricles
the 3rd centricle is between what
2halves of the thymus
What is required to move water soluble molecules across the blood brain barrier
mediated transport
What 2 arteries supply the brain
carotid and vertebral
Cranial nerve function is mostly what
somatic muscle control
