The Brain

SC.912.L.14. 26 Identify the major parts of the brain on diagrams or models.

BRAIN

• The Brain is a highly
organized ORGAN that
contains approximately 100
billion neurons.

• The Brain is Protected by a
• bony covering called the
SKULL.

• The SKIN protects the head
and brain.

BRAIN

In order for the Brain to
perform its functions, it
must have a constant
supply of Food and
Oxygen.

If the Oxygen supply to the
brain is cut off even for a
few minutes, the brain will
usually suffer enormous
damage. Such damage may
result in DEATH.

Cerebrum

• THE CONTROL CENTER OF THE

BRAIN.

• The LARGEST and most

PROMINENT part of the Human
Brain. 85% of the weight of a
human brain. The Cerebrum
takes up most of the space.

• Responsible for all the

VOLUNTARY (CONSCIOUS)
ACTIVITIES OF THE BODY. It is
the site of INTELLIGENCE,
LEARNING AND JUDGMENT.

The CEREBRUM is divided into
TWO HEMISPHERES: THE LEFT
AND RIGHT CEREBRAL
HEMISPHERES.

FUNCTIONS:
Speech/Language, Conscious
Thought, Memory, Personality,
Vision, Logic and Emotions,
Voluntary Movement,
Interpretation of Sensation,
and other sensations.

The Cerebrum

The Corpus Callosum is
the fibrous tract of white
matter that connects the
right and left cerebral
hemispheres.

Corpus callosum

The cerebrum is often divided
into five lobes that are
responsible for different brain
functions.

1. frontal lobe
2. temporal lobe
3. parietal lobe
4. occipital lobe
5. limbic lobe

The cerebrum is often divided into
five lobes that are responsible for
different brain functions.

1.frontal lobe
2.temporal lobe
3.parietal lobe
4.occipital lobe
5.limbic lobe

Frontal Lobe

• Contains the Primary Motor
Cortex (controls voluntary
movements of specific body
parts).

• Area of the brain
responsible for higher
cognitive functions.

•These include:

•Problem solving

•Spontaneity

•Memory

•Language

•Motivation

•Judgment

•Impulse control

•Social and sexual behavior

Temporal Lobe

The temporal lobe plays
a role in emotions, and
is also responsible for
smelling, tasting,
perception, memory,
understanding music,
aggressiveness, and
sexual behavior.

The temporal lobe is also
involved in language.

Temporal Lobe

•The back of the temporal lobe also contains a specialized area called Wernicke’s
area that is responsible for matching
written words with the sound of
spoken speech (language comprehension).

Parietal Lobe

The parietal lobe
plays a role in our
sensations of
touch, smell, and
taste. It also
processes sensory
and spatial
awareness

Occipital Lobe

The occipital
lobe is at the rear
of the brain.

It controls:

• vision

• recognition

Multiple Choice

What lobe is letter C

• frontal

• occipiatal

• temporal

• parietal

Multiple Choice

The part of the brain that is used for functions such a voluntary movement, problem-solving, emotional regulation, etc.

• Frontal Lobe

• Temporal Lobe

• Parietal Lobe

• Occipital Lobe

Multiple Select

The Occipital Lobe is responsible for what?

• Emotions

• Creative thinking

• Sensory functions

• Visual information

Multiple Choice

Which has to do with taste,  and spatial awareness?

• frontal lobe

• occipital lobe

• parietal lobe

• temporal lobe

Multiple Choice

Area of the temporal lobe involved in language comprehension.

• Broca's Area

• Wernicke's Area

• Central Sulcus

• Somatosensory Cortex

Cerebellum

The cerebellum is
connected to the
brainstem.

Functions:

• “autopilot” for

body movement
and balance.

Upper Brain Stem

• Contains important relay

centers that direct information
to and from different parts of
the brain

• Thalamus is a critical cite for

sensory processing and
relaying information to
appropriate areas of the
cerebral cortex

• Hypothalamus is

responsible for feeling of
hunger and thirst. Also,
regulates and controls may
hormones

Multiple Choice

Which of the following is NOT a part of the brainstem?

• Cerebellum

• Medulla oblongata

• Midbrain

• Pons

Multiple Choice

Which part of the brain controls your blood pressure and heart rate?

• brain stem

• occipital lobe

• cerebellum

• frontal lobe

Multiple Choice

Located in the hindbrain, this structure is responsible for coordinated movement and balance

• cerebellum

• medulla

• pons

• brain stem

Multiple Choice

This structure helps pass information between the two hemispheres of the brain.

• corpus callosum

• hypothalamus

• pons

• amygdala

Multiple Choice

Number 6 is the

Multiple Choice

This portion of the brain is responsible for hunger, thirst, blood pressure and body temperature.

• Medulla Oblongata

• Thalamus

• Midbrain

• Cerebellum
