1. NEUROANATOMY

3. Basic Anatomy
The central nervous system processes all information received from the outside world and controls all reactions to the outside world. It is composed of the brain and the spinal cord.
We will be examining the basic anatomy of the brain and spinal cord.

4. Let’s Dig Into Brain Anatomy

6. The Brain
The Brain is the control centre of the nervous system, where movement, emotions, personality, and memory is focused.
It is composed of four basic parts: The Cerebrum, the Diencephalon, The Brainstem, and the Cerebellum

7. The Cerebrum
The Cerebrum (cerebral cortex) is the area of higher level thinking
Memory, Personality, Logic, Reasoning, Creativity, and Decision making is focused here

10. The Diencephalon
The Diencephalon is the “Inner Brain”, composed of the Thalamus, Hypothalamus, Epithalamus, Pineal Gland
The Thalamus “Edits” what information is processed to the conscious brain in the cerebrum, but research show this information is still sent to the cortex

11. Diencephalon (Continued)
The Hypothalamus is responsible for the instinctual drives of the body (Four F’s of Life) as well as hormonal and regulatory roles

12. The Brainstem
The Brainstem is responsible for processing of higher level signals, and the running the systems of the body such as heart rate, breathing rate, wakefulness cycle and sleep.

13. Cerebellum
The Cerebellum is responsible for motor memory and programming of your muscles for various actions.

15. The Spinal Cord
The Spinal Cord sends signals from the brain, relays signals from the body, but also completes simple reflex arcs itself.

16. Spinal Cord (Cont.d)
The Spinal cord will control the body (extremities) response to stimuli
Simple Reflex Arcs are completed by the spinal cord, without the Brain
The Spinal Cord receives Sensory (Afferent) Neurons and then sends signals to Efferent (Motor) Neurons. (A to C to E)
