Lesson: The Brain – An Intro
Goal(s):



I can discuss causes and treatments for traumatic brain injuries.
I can describe the relationship among the brain, brainstem, and spinal cord.
I can identify the major anatomical sections of the brain.
Video Notes: Central Nervous System
1. What are the two divisions of the nervous system?
2. What is included in the CNS?
3. What are some functions of the brain?
4. What protects the brain?
5. “Your brain is divided into _________________ _____________ that may, or may not, interact with
each other to produce a given action.”
6. What does the cerebellum do?
7. What does the mid-brain do?
8. What are some things the “reptilian” brain does?
9. What is the largest region of the brain?
10. What are the sides of the brain called?
11. What does the “frontal” lobe control?
12. When does the “frontal” lobe finish developing?
13. What do each of the following areas of the brain do?

Occipital lobe:

Parietal lobe:

Temporal lobe:
Notes:
I.

General Facts:
The central nervous system (CNS) consists of the brain and spinal cord.

The brainstem connects the brain to the spinal cord.

Communication to the peripheral nervous system (PNS) is by way of the spinal cord.

•
Stores memory
•
Reasoning
•
Makes decisions
•
Coordinates muscular movements
•
Regulates visceral activities
•
Determines personality

III.
Major parts of the brain:
A. Cerebrum
1. Frontal lobes
2. Parietal lobes
3. Occipital lobes
4. Temporal lobes
5. Insula
B. Diencephalon
C. Cerebellum
D. Brainstem
1. Midbrain
2. Pons
3. Medulla oblongata
IV.
Structure of the Cerebrum
A. Cerebral hemispheres - 2 halves, separated by falx cerebri
B. Corpus callosum - Connects cerebral hemispheres
C. Gyri - Ridges or convolutions
D. Sulci - Shallow grooves in surface
E. Fissures - Deep grooves in surface
i. Longitudinal: separates the cerebral hemispheres
ii. Transverse: separates cerebrum from cerebellum
V.
Lobes of the Cerebellum
1. Frontal lobe
2. Parietal lobe
3. Temporal lobe
4. Occipital lobe
5. Insula (Island of Reil)
VI.
Functions of the cerebellum:
•
Interpreting impulses
•
Initiating voluntary movements
•
Storing information as memory
•
Retrieving stored information
•
Reasoning
•
Seat of intelligence and personality
