The Nervous System Our Control Center

What controls our body functions? When you Blink? When you breath? When you smell a fart? When you are hungry? Have to go pee?

The Nervous System Brain Anatomy Functions Sensory system Anatomy Functions

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

Cerebellum Coordination Balance Reflex motor activity

Pons Consciousness Sleep

Medulla Oblongata Brain Stem Breathing Pumping the heart Hunger Urination Swallowing Gag reflex

Nervous Systems Central 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

Spinal Cord

Nerve Cells Neurons Ganglia Connect with multiple cells to make up nerve tissues

Sensory Organs Eye Ear Olfactory Cells Taste Buds

Eye Cornea Lens Iris Pupil Retina Optic Nerve

Ear Outer ear Middle ear Inner ear

Olfactory System Cells that detect odors in the air and sends chemical messages to the brain

Taste Buds Papallea Average: 10,000 in your mouth Sends signal to brain about what you are tasting Bitter Sweet Sour Salty

Papillae Small hair like cells that taste what you eat

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

The Nervous System Controls everything that our body does

The Nervous System Without it we are unplugged
