The Nervous System

Cerebrum

Telencephalon

lateral ventricles

What is the largest ventricle?

Frontal lobe

Parietal lobe

Occipital lobe

Temporal lobe

Longitudinal Fissure

Separates the left and right cerebral hemispheres, the falx cerebri is found here

Corpus Callosum

Connects the left and right cerebral hemisphere and is their main mode of communication

Cerebellum

muscle memory, equilibrium, posture, proprioception

Arbor Vitae

Tree of life

midbrain, pons, medulla oblongata

The brainstem includes (rostral to caudal)

midbrain

pons

Bridge

relays impulses and helps to regulate breathing

Medulla Oblongata

Functions include sensory relay for cranial nerves, relay for thalamus, cardiac center,vasomotor center, respiratory center

Pituitary gland

sella turcica

Lateral Ventricles

Third Ventricles

Fourth Ventricle

Choroid Plexi

found in each ventricle

Meninges

Connective tissue membranes that surround and separate portions of the brain.

dura mater, arachnoid mater, pia mater

3 layers of meninges (outer to inner)

dura mater

most superficial layer of meninges

falx cerebri

in the midsagittal plane

Where is the dura mater and falx cerebri located?

anterior: crista galli - posterior: superior portion of the tentorium cerebelli

Where is the dura mater and falx cerebri anterior attachment and posterior attachment?

tentorium cerebelli

tentorial notch

the space in the tentorium through which the brainstem passes

arachnoid mater

pia mater

deepest layer of meninges

optic nerves

runs through optic foramen

optic chiasm

olfactory bulb

olfactory tract

spinal nerves

conus medullaris

cauda equina

thicker fibers / horse tail

Filum Terminale

thin fibers

corpus callosum
