** (CH.3) ** · Body’s electrochemical communication circuitry. ü Human nervous system is made up of billions of nerve cells · The Brain and Nervous System move the body.
 * THE NERVOUS SYSTEM **

DIVISIONS of THE NERVOUS SYSTEM //__ Central Nervous System __// · Spinal cord · Brian · Mid and forebrain

//__ Peripheral Nervous System __// · Somatic nervous system ü Sensory nerves · Automatic nervous system ü Takes messages to and from the body’s internal organs.

v Cell body- part of a neuron that contains nucleus. //__ Sympathetic Nervous System __// · Flight · Fight ü Eyes, lings, heart, stomach, blood vessels

//__ Parasympathetic Nervous System __// · Feeding · Forceniction ü Pupils get smaller, lungs and heart go slower, food digest slower, blood vessels go slower as well.

//__ (LEFT Hemisphere) __// – speech and language · Right hand and controls right side of the body · Academics body side

//__ (Right Hemisphere) __// · Left hand and controls left side of the body · Music and dance

__//Cerebral Cortex Lobes//__

· // Frontal lobe- // smell, personality, sexuality, movement and emotions · // Temporal lobe // - hearing and visual · // Occipital // - vision · // Parietal lobe // - touch, taste, hear

//__ Methods of the Brains __// · Computerized Axial Tomography- cat scan, X-ray · Magnetic Resonance Image- MRI · Position Emission Tomography- pet scan

// Hind Brain // - located at the skull. // Brain Stem // - the medulla, pons, and other parts of the hindbrain are together. // Mid brain // - located between the hindbrain and the forebrain. // Fore Brain // - largest division part

1. Define and give examples of afferent and efferent nerves.

2. Draw and label: A) Cell Body B) Dendrites C) Nucleus D) Axon E) Myellin sheath F) Terminal Button G) Synapse

3. Parasympathetic or Sympathetic Branch? 1. Accelerates heartbeat= 2. Stimulates flow of saliva= 3. Dialates Pupil=

4. ____________is a hormone and neurotransmitter that plays important roll in the experience of love and social bonding.

5. Describe 3 ways to allow researchers to examine the brain while functioning.
