What controls our body functions?
•When you Blink?•When you breath?
•When you smell a fart?•When you are hungry?• Have to go pee?
Central Control
•The Brain•Cerebral Cortex (Cerebrum)•Cerebellum•Pons•Medulla Oblongata (Brain Stem)•Spinal Cord
Cerebral Cortex• Largest part of the brain•Responsible for:–Motor Skills, Judgment, Analytical
reasoning–Emotions, Sensations, Storing data–Memory, Speech
Medulla Oblongata• Brain Stem• Breathing• Pumping the heart• Hunger• Urination• Swallowing• Gag reflex
Nervous SystemsCentral Nervous System
• Brain• Spinal Cord• Retina
Peripheral Nervous System
• All of the other sensory nerves
Spinal Cord• 43 cm long in females / 45 cm in
males• Connects the peripheral nerves
to the brain• Nerve “Roots” extend to connect
to certain sections of the body
Taste Buds•Papallea•Average: 10,000 in your mouth•Sends signal to brain about what you are tasting•Bitter•Sweet•Sour•Salty
The Nervous System Problems
• Severe a nerve = loss of signal flow• Compress nerves = impede nerve flow• Epilepsy = Seizures• Cataracts = Clouding of the lens in the
eye• Otitis media = inner ear infection
