Question: What does the cerebral cortex cover?

Glossary

Today’s Plan

• Warm-up• Brain notes• Hemispheres of your brain• Reflection

Brain Notes: Please copy these questions onto page 3 of your SNB.

1. What are the three anatomical regions of the brain?

2. What are the four lobes of the brain? Name a function of each region.

3. What is the Cerebral Cortex? 4. What is the function of the spinal cord?

5. Name one function of the hypothalamus.

6. Name one function of the pituitary gland.

THE BRAIN

•ANATOMICAL REGIONS oCerebrumoCerebellumoBrain Stem

CEREBRUM - wrinkly large part of the brain, largest area in humans, higher mental function

CEREBELLUM

•Balance and coordination

Brain Stem -   regulates visceral functions (autonomic system)

Lobes of the Brain (general functions)

5.  Frontal – reasoning, thinking, language

6. Parietal – touch, pain, relation of body parts (somatosensory) 7.  Temporal Lobe – hearing

8.  Occipital – vision

Cerebral Cortex - thin layer of gray matter that is the outermost portion of cerebrum (the part with all the wrinkles)

Optic Tract / Chiasma - optic nerves cross over each other

Spinal Cordpasses down the vertebral canal, has 31 segments  (each with a pair of spinal nerves)

FUNCTION: conducting nerve impulses, serves as a center for spinal reflexes

Hypothalamus - hormones, heart rate, blood pressure, body temp, hunger.(Thalamus – relay station)

Pituitary Gland

The "master gland" of the endocrine system.  It controls hormones.
