Direction Terminology above the midbrain
Anterior = front of skull
Posterior = back of skull
Ventral = base of skull
Dorsal = top of skull
What are the components of the forebrain?
-Significant relay center for sensory input to the cerebrum
-integration of info passing from brainstem and spinal cord to cerebral hemispheres
-integration of motor and visceral
Cerebral hemispheres functions
Integrate the highest mental functions such as awareness of sensation, emotions, learning, memory, intelligence, creativity, and language
What part of the forebrain receive CN I?
What part of the forebrain receive CN II
1. In diencephalon
2. continuous with cerebral aqueduct
1. In cerebral hemispheres
What separates lateral ventricals?
1. where the cerebral aqueduct drains into
2. b/w brain stem and cerebellum
Pathway of CSF within the brain
1. Lateral ventricle
2. 3rd Ventricle
3. cerebral aqueduct
4. 4th ventricl
Interventricular foramen of Monroe
CSF drains from lateral ventricles to 3rd ventricle via this
CSF moves through here to the cerebral aqueduct
What connects the Thalamus?
Which sense does not pass through thalamus?
Which part of the diencephalon is found on the ventral surface of the brain?
- Medial to subthlamus
- Forms the floor for 3rd ventricle
- found on ventral surface
What is lateral to each thalamic mass?
posterior limb of internal capsule
- Ventral to thalamus
- Lateral to hypothalamus
- Dorsal to post. part of 3rd ventricle
- two parts: Habenual, pineal gland
Parts of Hypothalamus (ant-post)
Mamillary region of Hypothalamus
in rostral part of interpeduncular fossa
Tuberal region of Hypothalamus
- contains infundibulum (stalk of pituitary)
- referred to as infundibular region
separates frontal/parietal from temporal
b/w frontal and parietal
Preoccipital notch and parieto-occipital sulcus
imaginary line b/w the two separate the occipital from parietal/temporal
Fissure of sylvus
AKA lateral sulcu
FIssure of Rolando
AKA central sulcus
- dorsal to corpus callsum
- dorsla to callosal sulcus
- encircle the cingulated gyrus
separates the parietal and occipital lobes
