Front 30

Cerebrum

Back 30

Largest part of the brain

Responsible for voluntary activity

Vision, hearing, smell, taste, and memory

Front 31

Cerebral cortex

Back 31

Outter region of the brain

Contains sheets of nerve cells which makes the grey matter of the brain

Front 32

Gyrus (P) gyri

Back 32

Sheets of nerve cells produce the round ridges on the surface of the cerebral cortex

Convolution

Front 33

Sulcus (P) sulci

Back 33

Front 34

Cerebral hemisphere

Back 34

Division if the brain in left and right sides

4 lobes

Front 35

Cerebellum

Back 35

Anterior part if the brain

Responsible for the voluntary muscle movement, balance, posture

Front 36

Pons

Back 36

Anterior to the cerebellum. Acts as the

to the cerebellum. Acts as the brain stem as well as the bridge to various parts of the brain. Contains nerve fiber tract that connect the cerebrum and the cerebellum to the rest of the brain

Front 37

Medulla oblongota

Back 37

Located just able the spinal cord.

Good things nerve fiber trucks that go from right to left and left to right. Contains three vital centers for internal activity of the brain.

1. Respiratory center: muscles of respiration respond to chemical or other stimuli

2. Cardiac Center: slows the Heart when it is beating to rapidly

3. Vasomotor center: affects (dilates) the muscle walls of the blood vessals thus influencing the blood pressure

Front 38

Meninges

Back 38

3 layers of connective tissue membranes that surround and protect the brain and spinal cord

1. Dura Mater: outermost layer of the meninges contains channels (dural sinuses) that contain blood

>subdural space: beneath the Dura mater

2. Arachnoid membrane: middles layer of the meninges, contains web-like/ finger-like fibers that are loosely attached to the other membranes and in that space is fluid

>subarachnoid space: contains CSF

3. Pia Mater: innermost layer of the meninges that contains a rich supply of blood vessals

Front 39

Hydrocephalus

Back 39

Abnormal accumulation of fluid in the brain
