Enduring Understanding: The brain is the control center of the

body. The numerous sections of the brain carry out specific tasks

that function in maintaining homeostasis.

Essential Questions: What are the major parts of the brain?

SC.912.L.14.26 : Identify the major parts of the brain on diagrams or models.

Bellwork

Examine the diagrams below. Do you think this is a

survivable injury? Why or why not? Please explain.

External Features of the Brain Structure Function

Cerebral

hemispheres

Largest part of the brain. Large

paired structures, divided into

left and right hemispheres

Carries out higher thought processes

involved with language, learning,

memory, and voluntary body

movements

Cerebellum

Means “little brain”

Smaller structure under the

base at the back of the brain

Responsible for balance and

coordination

Brainstem

Extending from the base of the

brain; this continues into the

spinal cord, made up of the pons

and medulla oblongata

Relays signals between the brain and

spinal cord

The Brain Stem Brain Stem

Region Structure Function

Pons Top region of the brain stem

Relays signals between cerebrum and

cerebellum.

Helps control breathing rate

Medulla Oblongata

Beneath the pons, lower portion of the

brainstem.

Connects to the spinal cord.

Relays signals between the brain and the

spinal cord.

helps control blood pressure, heart

rate, and breathing rate.

Lobes of the Brain Structure Function and other notes

Frontal lobe conscious thought, behavior, emotion, planning, personality, organizing, problem

solving. Most uniquely human of all the brain structures. Front of the brain

Parietal lobe Integrations of sensory information from primary sensory areas perception,

arithmetic, spelling, manipulation of objects. Middle top of the brain.

Temporal lobe Senses of smell and sound, as well as processing of complex stimuli like faces and

scenes, memory, understanding language. Temple region.

Occipital lobe Sense of sight

Extreme back of the brain

Based on the diagram, damage to which of the

following lobes would result in hallucinations?

Frontal

Parietal

Temporal

Occipital

Based on the diagram, damage to which of the

following lobes would result in mood changes and/or

social differences?

Brain Cap Activity: Step 1

Mark the lobes we discussed on your cap with a permanent marker.

Be sure to include the cerebellum.

Brain Cap Activity: Step 2 Map the functional areas as seen in the diagram below with different colored permanent

markers. The brain is both anatomically and functionally segregated. Different function

are located in particular regions of each lobe.
