Median Section of the Human Head

Bone of Skull

A

Superior Sagittal Sinus

B

Cerebral Hemisphere: processes higher brain functions

C

Arachnoid Villus

D

Dura Mater: outermost meninge, protects spinal cord

E

Septum Pellucidum: separates the lateral ventricles

F

Choroid Plexus: makes cerebrospinal fluid

G

Fornix: concerned with olfaction

H

Corpus Callosum: connects cerebral hemispheres

I

Arachnoid Mater: middle meninge, protects spinal cord

J

Cerebral Hemisphere: processes higher brain functions

1

Optic Chiasma: area where the medial portion of optic nerves cross

2

Infundibulum

3

Pituitary Gland: produces hormones

4

Mammillary Body: relay station for olfaction

5

Cerebral Aqueduct: takes cerebrospinal fluid from the third to fourth ventricle

6

Inferior Colliculi of Corpora Quadrigemina: contains auditory reflex center

7

Cerebellum: controls balance/equilibrium

8

Straight Sinus: involved in CSF flow

9

Superior Colliculi of Corpora Quadrigemina: contains visual reflex center/

10

Pineal Body: produces hormones

11

Third Ventricle: takes cerebrospinal fluid from the interventricular foramen to the cerebral aqueduct

12

Intermediate Mass of the Thalamus: connects the two thalamic lobes & bridges the ventricles

13

Thalamus: relay station from sensory impulses to localization/ interpretation areas

14

Cerebral Aqueduct: takes cerebrospinal fluid from the third to fourth ventricle

A

Pons: contains motor & sensory fiber tracts that connect brain w/ lower CNS centers

B

Fourth Ventricle: takes cerebrospinal fluid from the cerebral aqueduct to the central canal or foramina

C

Spinal Cord: reflex, association, and communication area

D

Third Ventricle: takes cerebrospinal fluid from the interventricular foramen to the cerebral aqueduct

E

Cerebellum: controls balance/equilibrium

F

Arbor Vitae: propagates impulses from visual input

G

Medulla Oblongata: houses autonomic centers controlling heart rate

H

Spinal Column

I
