Main Function: Main Function: This communication system controls and coordinates functions throughout the body and responds to internal and external stimuli. Our nervous system allows us to feel pain.

Consists of: brain, spinal cord, nerves and sense organs Sense Organs: Eyes, Skin, Ears, Nose & Tongue

brain Spinal Cord Cerebellum Cerebrum Medulla Oblongata Consists of: Brain and Spinal Cord Its function is to interpret, store, and respond to information received from inside and outside.

CerebrumVoluntary or conscious activities of the body-learning, judgment CerebellumCoordinates and balances the actions of the muscles Medulla Oblongata (Brain Stem) Controls involuntary actions like blood pressure, heart rate, breathing, and swallowing Spinal Cord The main communications link between the brain and the rest of the body

Cerebrum Voluntary or conscious activities of the body-learning, judgment

Cerebellum Coordinates and balances the actions of the muscles

Medulla Oblongata (Brain Stem) Controls involuntary actions like blood pressure, heart rate, breathing, and swallowing Brain Stem

Consists of: Sensory division and Motor division -includes all sensory neurons, motor neurons, and sense organs

A nerve is an organ containing a bundle of nerve cells called neurons. Neurons carry electrical messages called impulses throughout the body. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). Picture shows hundreds of severed neuron axons

cell body muscle tissue TYPICAL MOTOR NEURON Axon dendrite synapse cell body

Parts of a Neuron 1. Cell body: contains nucleus & most of the cytoplasm 2. Dendrites: projections that bring impulses into the neuron to the cell body. 3. Axon: long projection that carries impulses away from cell body 1 3 2
