Front 11

The Cerebrum is responsible for all the _ or _ activities of the body.

Back 11

Voluntary or Conscious

Front 12

It is the site of _, _, and _

Back 12

Intelligence, Learning, and Judgment

Front 13

The cerebrum is divided into two _, the left and right _ _

Back 13

Hemispheres
Cerebral Hemispheres

Front 14

There is a _ _ that separates the two hemispheres

Back 14

Deep Groove

Front 15

The hemispheres are connected in a region known as the _ _

Back 15

Corpus Callosum

Front 16

The right and left cerebral hemispheres are linked by a bundle of _ called a _

Back 16

Neurons called a Tract

Front 17

This _ tells each half of the brain what the other half is doing

Back 17

Tract

Front 18

The most obvious feature on the surface of each hemisphere are _ _

Back 18

Numerous Folds

Front 19

These folds are groves _ the surface area of the cerebrum

Back 19

Front 20

It contains thick layers of unmyelinated neurons, which look _

Back 20

Grey

Front 21

Each hemisphere of the cerebrum is divided into regions called _

Back 21

Lobes

Front 22

The cerebrum consists of _ _

Back 22

Two Surfaces

Front 23

The outer surface is called the _ _ and consists of grey matter ( _ neurons)

Back 23

Cerebral Cortex
Unmyelinated Neurons

Front 24

The inner surface is called the _ _ which is made up of bundles of _ axons

Back 24

Cerebral Medulla
Myelinated Axons

Front 25

The _ gives the white matter its white color

Back 25

Myelin

Front 26

The _ is the second largest part of the brain, and is located at the back of the skull

Back 26

Cerebellum

Front 27

The cerebellum coordinates _ movements

Back 27

Muscle

Front 28

The cerebellum controls _, _, and _

Back 28

Balance, Posture and Coordination

Front 29

This is a small _ -shaped structure, while well-developed in mammals, is even more developed in birds

Back 29

Cauliflower

Front 30

Because the function of the cerebellum is _, learning a completely new physical activity can be very difficult

Back 30

Front 31

The _ _ connects the _ to the _ _

Brain Stem
Brain
Spinal Cord

Front 32

The brain stem which maintains _ _ _ consist of four parts:

Back 32

Life Support System
- Diencephalon
- Medulla Oblongata
- Pons
- Midbrain

Front 33

The _ _ controls vital body processes

Back 33

Brain Stem

Front 34

The lowest part of the brain stem is the _ _

Back 34

Medulla Oblongata

Front 35

The medulla contains _ matter that conducts impulses between the spinal cord and brain

Back 35

White

Front 36

The medulla controls _ functions that include breathing, blood pressure, heart rate, digestion, swallowing and coughing

Back 36

Involuntary

Front 37

Another important part of the medulla is a group of cells known as _ _ _ (RAS)

Back 37

Reticular Activating System

Front 38

The Reticular Activation System actually helps to _, or _, the upper parts of the brain, including the cerebral cortex. Such actions keep the brain alert and conscious

Back 38

Alert or Awaken

Front 39

Just above the medulla, the brain stem enlarges to form _

Back 39

Pons

Front 40

Pons means _, and this area of the brain stem contains mostly _ matter that provides a _ between the cerebral cortex and the cerebellum

Back 40

Bridge

Cerebral Cortex and the Cerebellum

Front 41

Above the pons and continuous with it is the _, the _ division of the brain stem

Back 41

Midbrain
Smallest

Front 42

The thalamus and hypothalamus are found in the part of the brain between the _ _ and _

Back 42

Brain Stem
Cerebrum

Front 43

The thalamus, which is composed of grey matter, serves as a switching station for _ input. With the exception of _, each sense channels its sensory nerves through the _

Back 43

Sensory

Thalamus

Front 44

The thalamus passes information to the proper region of the _ for further processing

Back 44

Cerebrum

Front 45

Immediately below the thalamus is the hypothalamus, which is the _ _ for hunger, thirst, fatigue, anger and body temperature

Back 45

Control Center

Front 46

Parts of the diencephalon and the cerebrum are included in an important group of connected brain centers called the _ _

Back 46

Limbic System

Front 47

The upper part of the brain stem, the _, contains important relay centers for information _ and _ the brain

Back 47

Diencephalon
