Typical Neuron

Typical Neuron with Glial Cells (supportive cells)


2 main nervous systems
2 Main Nervous Systems

  • Central Nervous System (CNS)

    • Includes only the brain and spinal cord

  • Peripheral Nervous System (PNS)

    • Cranial Nerves-12 pairs (sensory, motor or both)

    • Spinal Nerves-31 pairs (sensory and motor)

      • Sensory nerves- eyes, nose, skin, ears, and tongue

      • Motor nerves- allows movement

      • Autonomic Nervous System (ANS)-involuntary

      • Sympathetic Nervous System- speeds reactions

      • Parasympathetic Nervous System- slows reactions

        -Somatic Nervous System (SNS)- Voluntary


The 3 main regions of the brain 1 cerebrum state of consciousness external parts
The 3 Main Regions of the Brain: 1. Cerebrum- state of consciousness External parts

  • Frontal lobe or cortex: Emotional control and personality development

  • Temporal: Sensory input, language, and memory

  • Parietal: Sensation, perception, integrating sensory input mostly with visuals

  • Occipital: Visual perception (color, visual spatial processing, and discriminating movement)

  • More Information: http://www.neuroskills.com/


Central Sulcus (groove)

Lateral Fissure (deep)


Cerebrum cerebral cortex
Cerebrum: Cerebral Cortex

  • Gray matter- is the outer layer of the brain that is darker and made up of cell bodies

    • Motor areas

    • Sensory areas

    • Association areas- responsible for thought, learning, judgment, personality, memories and connects sensory and motor areas

  • White matter- is the lighter inner layer of the brain that is made up of many axons

    • Responsible for connecting areas within the same hemisphere together



Internal parts of the cerebrum
Internal parts of the Cerebrum:

  • Thalamus- sensory relay

    influences mood and movement

  • Hippocampus- short term

    and long term memory;

    spatial navigation

  • Corpus Callosum- connects the right and left brains together


More internal parts of the cerebrum
More internal parts of the Cerebrum

  • Amygdala- Initial emotional center for immediate reaction

  • Hypothalamus-Maintains homeostasis and regulates hormones


Internal parts of the cerebrum1
Internal parts of the Cerebrum:

  • Pineal Body- associated with hormones and navigation (inhibits cancer)

  • Pituitary Gland associated with hormones for growth

Pituitary Gland


The main regions of the brain 2 cerebellum
The Main Regions of the Brain: 2. Cerebellum

  • Cerebellum- (Right and Left sides)

    involved in the coordination of voluntary motor movement, balance equilibrium and muscle tone


3 brain stem
3. Brain Stem

  • Brain Stem- cranial nerves and spinal nerves found here, controls involuntary functions: heart rate, breathing rate, blood pressure etc.

    • Pons

    • Medulla Oblongata

    • Midbrain

Try using your brain stroop test
Try using your brain: Stroop TEST

  • Dr. John Ridley Stroop 1935

  • Directed attention: you have to manage your attention, inhibit or stop one response in order to say or do something else.

Something in a thirty-acre thermal thicket of thorns and thistles thumped and thundered threatening the three-D thoughts of Matthew the thug - although, theatrically, it was only the thirteen-thousand thistles and thorns through the underneath of his thigh that the thirty year old thug thought of that morning.
