Lecture 11 Flashcards
What is the thalamus?
relay station for sensory and motor information entering the cerebrum
What fibers are in the white matter?
association, commissural, and projection
What are commissural fibers?
Where is the location of conscious thought processes and complex intellectual functions?
cerebrum
Where are gray matter and white matter found?
the cerebrum
What does the frontal lobe do?
decision making, personality, verbal communication, voluntary motor control of skeletal muscles
How many ventricles are there in the brain?
four
What do descending pathways do?
conduct motor information from higher CNS processing centers to the spinal cord and brainstem
Where are descending pathways of nerves found?
White matter and anterior side of the spinal cord
What is hydrocephalus?
excessive cerebrospinal fluid
Where is the thalamus found?
on either side of the third ventricle
What is the cerebrum?
squiggly part of the brain
What does the temporal lobe do?
auditory and olfactory experience
What do the two hemispheres make up?
the cerebrum
What is part of the brainstem?
midbrain, pons, medulla
What is the diencephalon made of?
thalamus, hypothalamus, and epithalamus
What does the brainstem contain?
many autonomic and reflex centers essential for survival
What is the limbic system?
“emotional brain”
What is the function of cerebrospinal fluid?
buoyancy, protection (cushion), environmental stability
What are the two hemispheres connected by?
corpus callosum
What are the reflexes that medulla controls?
coughing, sneezing, gagging, vomiting, etc.
What are the functions of the hypothalamus?
Behavior, Endocrine, Emotion, Temperature control, Sleep/wake cycles, Hunger/thirst, Autonomic control, Memory
What does the occipital lobe do?
vision
What are projection fibers?
