The Nervous System

• -Frontal Lobe
• -Parital Lobe
• -Temporal Lobe
• -Occipital Lobe

• - Brain
• - Spinal Cord
• - Meninges

• - Ability to recognize objects
• - Vision

• - hearing
• - taste
• - smell
• - language
• - memory

• "Sense"
• - touch
• - pain
• - taste
• - pressure
• - temperature

• - relay center for nerve conduction
• - relay sensory impulses to the cerebral cortex

• Controls...
• - temperature
• - sleep or awake states
• - emotion
• - hunger (appetite)
• - fluid volume
• - thirst
• - production of pituitary

- store information

- an organ system containing a network of specialized cells called neurons that controls actions & transmit signals between different parts of the body

- communication system

- nerve & electrical impulses

• - posture
• - balance
• - muscle tone/ movement

• - located below occipital
• - 2nd largest part of brain
• - above brain stem

• - mid- brains
• - pons
• - medulla oblongta

• - Below cerebellum
• - Upper part of spinal cord

• - breathing
• - digestion
• - heart rate
• - blood pressure
• - relay center for spinal cord
• - arousal (awake & alert)

- Extends from medulla oblangta to 2nd lumbar bertebrae

• I.
• - Sense of smell

• II.
• - Sense of sight

• III.
• - Mvement of eyeball

- Neural impulse is sent to central nervous system from receptor or sensory organ.

- Neural impulse is set to receptor or enory orga from central nervous system.

- Nerve cell found throughout the entire CNS that link between sensory neurons & motor neurons.

• - dendrites
• - Axons

Move impulses along

- Recieves impulses

- Conducts the impulses away from cell body.

- Nerve bundles

- Space between nerves o transmit information from one nerve to another

- A chemical that is released to transmit messages from one cell to another

- Produce nerve fibers

• - Insulate nerve
• - Allow rapid & efficient transmission of impulses along the nerve cells

- Starts nerve impulses

- stops nerve impulses

• - Consist of nerves & ganglia
• - Located outside of CNS

- Ventricle of your brain

• - Protection; cusion
• - Keep the pressure on the brain even
• - Keep harmful waste away from the brain
• - Keep the brain & spinal cord moist

• - Pia Mater
• - Arachnoid
• - Dura Mater

• - Thalamus
• - Hypothalamus

• - Middle layer
• - Spider-web like
• - Has blood vessels laced throughout it

• - Innermost layer
• - laced with blood vessels or capillary beds
• - brains main supply of nutrients
• (nourish the brain)

• - hard, tough, thick outermost layer of meninges
• - Protects brain & spinal from displacement

• - determines intelligence
• - Personality
• - sensory impulses
• - motor functions
• - planning/ organization
• - speech
• - etc.

• - emotions
• - judgement
• - the way you think
• - speech
• - problem solving
• - reasoning
• - voluntary movement

• - known as the "big brain"
• - biggest part of brain

• - increase the surface
• - support complex nerve networks

• - left side controls right side of body
• - right side controls left side of body

- outside covering of the brain (cerebrum)

- protect the central nervous system

- protection for CNS
