…it’s what’s for dinner.

2. The brain
As we learned yesterday, the brain is part of the central nervous system.

3. The brain The brain is the control center of the body.
It controls everything from primitive emotions (happiness and anger) to more complex functions (self-control and abstract thinking)
It also controls actions, from talking to digesting
It even keeps your body in homeostasis.

4. Brain-y Vocabulary Lobe – A curved or rounded projection or division
Sulcus – A shallow furrow (depression or fissure) in the surface of the brain (plural – sulci)
Gyrus – A convoluted ridge (elevated area) between anatomical grooves (plural – gyri)

6. Layers of the brain From Superficial to Deep Skin & Hair Skull
Dura Mater
Arachnoid Layer
Cerebrospinal Fluid
Pia Mater
Brain Tissue

7. Divisions of the brain
Cerebrum: contains 4 lobes, has left and right hemispheres
Cerebellum: Motor Skills, Attention, Language & some emotion
Brainstem: Autonomic Functions, Sensory reception

8. the 4 lobes of the cerebrum
Frontal Lobe
Parietal Lobe
Learning Social Norms
Decision-making
Long-term memory
Sensory Input
Object manipulation
Visuo-spatial processing

9. the 4 lobes of the cerebrum
Occipital Lobe
Temporal Lobe
Primary Visual Cortex
Dreams originate here
Speech
Comprehension
Verbal Memory
Naming
Language

10. Brain parts Cerebellum Brain Stem Means ‘little brain’ Regulates
balance
Posture
movement
Connects the cerebral hemispheres with cerebellum
Contains:
Thalamus: cortex for sensory processing
Hypothalamus – a gland that controls many important function

12. The brain is made of Gray matter acts as a computer processer!
Neural cell bodies and dendrites
Gray matter controls:
Muscle control
Sensory perception
Memory, emotions and speech
Gray matter carries information from the internal and external environments to the brain
Gray matter acts as a computer processer!

13. Gray and White matter White Matter
Mostly myelinated axons
White matter connects various gray matter of the brain to each other and carry nerve impulses between neurons
White matter acts as the wires that connect computers together!

14. Spinal Cord
A long, thin tubular bundle of nervous tissue and support cells that extends from the brain
Like the brain, it contains gray and white matter

15. Functions of Spinal Cord
Sends sensory information up to the brain
Sends motor information down from the brain
Serves as a center for coordinating certain reflexes

16. Spinal Cord Diagram
The dorsal (posterior) roots carry afferent sensory nerves, while the ventral (anterior) roots carry efferent motor nerves.

17. Questions Which part of your brain acts as the computer processor?
Which part of your brain acts as the wiring to connect it?
What is the name of the material that ‘insulates’ the axons?
