Outcome 6 - Review Flashcards
4 main regions of the brain.
- cerebrum
- diencephalon
- cerebellum
- brainstem
Which is the largest portion?
cerebrum
Which portion forms the central core?
diencephalon
Which portion occupies the inferior and posterior aspect of the cranium?
cerebellum
Which portion connects the brain and spinal cord?
brainstem
Which lobe(s) is/are responsible for hearing and smelling?
temporal
Which lobe(s) is/are responsible for movement of voluntary skeletal muscles?
Frontal
Which lobe(s) is/are responsible for the detection sensations of touch, pressure, pain and temperature?
parietal
Which lobe(s) is/are responsible for vision?
occipital
What band of white matter connects the 2 hemispheres?
corpus callosum
What deep groove separates the 2 cerebral hemispheres?
longitudinal fissure
What deep groove separates the cerebellum from the cerebrum?
transverse fissure
What sulcus divides the frontal and parietal lobes?
central sulcus
What major fold is located just anterior to this sulcus? Just posterior?
pre central gyrus and post central gyrus
What sulci divide the frontal and temporal lobes?
lateral cerebral sulci
What sulcus divides the parietal and occipital lobes?
parieto-occipital sulcus
What is the superficial layer called? What type of matter is found here?
cerebellar cortex - gray matter
Where is the white matter located? What is it called?
visceral to the cerebellar cortex
arbor vitae
What are cerebellar nuclei?
regions of gray matter scattered throughout white matter
What are the primary functions of the cerebellum?
evaluates coordinated muscle movements
balance and posture
What 3 components make up the diencephalon?
thalamus, hypothalamus, epithalamus
Which is the most anterior part of the diencephalon?
hypothalamus
Which is the most posterior part of the diencephalon?
epithalamus
Which is the largest part of the diencephalon?
thalamus
Which part of the diencephalon functions as a relay station for sensory information?
thalamus
Which part of the diencephalon functions is involved in ANS control and hormonal production?
hypothalamus
Which part of the diencephalon functions includes the pineal gland?
epithalamus
What are the 3 parts of the brainstem?
- midbrain
- pons
- medulla oblongata
Which part contains the decussation of pyramids?
medulla oblongata
what part of the brainstem controls vital reflexes?
medulla oblongata nuclei – cardiovascular center, medullary resp. center
What portion of the brain stem connects parts of the brain with one and other?
pons = bridge
What portion of the brainstem contains the cerebral aqueduct that connects the 3rd and 4th ventricle?
midbrain
What is responsible for formation of the CSF?
choroid plexuses
How does the CSF get from the lateral ventricles to the 3rd ventricle?
inter ventricular foramina
How does CSF get from the 3rd to 4th ventricle?
cerebral aqueduct or aqueduct of the midbrain
Where does the CSF go after leaving the 4th ventricle?
Central canal of spinal cord and subarachnoid space of brain and spinal cord (via the lateral and median apertures)
How is CSF reabsorbed?
arachnoid villi
