 Somatic or Autonomic

 Sensory  Integrative  Motor

 Conducting Nerve Impulses  Serving as a Center for spinal reflexes

 How it works with other body systems.

 Cerebrum  Diencephalon  Brainstem  Cerebellum

 2 Hemispheres with corpus callosum  5 nerve centers (Frontal, temporal, parietal, occipital, insula)  Cerebral cortex

 Interpret sensory impulses, initiate voluntary muscle movements, stores memory  Function depends on region; 3 Regions:  Motor  Sensory  Association

 Motor Speech Area- mouth, tongue, layrnx = speech  Frontal Eye Field- eyes and eyelids (voluntary) Impulse Down brainstem Through spinal cord Synapse Muscle fibers

Sensory Interpret impulses from sensory receptors Parietal lobes Occipital lobes Temporal lobes Association Interpret sensory experiences, oversee memory, reasoning, verbalizing, judgment, emotion Anterior portion Lateral portion General Interpretative area

 Thalamus- central relay station  Hypothalamus- regulates homeostasis  Limbic System- controls emotional experience and expression

 Midbrain- connects brainstem and spinal cord, reflex centers  Pons- separate midbrain and medulla, relay impulses  Medulla Oblongata- everything passes through it  Reticular Formation- activates cerebral cortex  Choroid Plexuses- secrete cerebrospinal fluid

 Superior Peduncles  Inferior Peduncles  Middle Peduncles

 Functions independently  Regulates viscera

Sympathetic Energy expending, stressful, or emergency Parasympathetic Ordinary, restful conditions

 Touch & Pressure  Temperature  Pain

 Free-Nerve Endings- epithelial tissue  Meissner’s Corpuscles- connective tissue (no hair)  Pacinian Corpuscles- connective tissue (subcutaneous)

70 °-113°F More=Pain Warm 50 °-68°F Less=Pain Cold *Adapt Rapidly

 Protect  Adapt Poorly  Decreased blood flow accompanied by lower oxygen concentration  Viscera

Thin, myelinated Rapid, sharp pain Skin Acute Thin, unmyelinated Slow, Dull ache Deeper Can cause prolonged suffrage Chronic Can cause prolonged suffrage Regulation of pain impulse

 Both have their own neuron process  Flavor- a combination of what you taste and smell

 Multiple Sclerosis- damages the myelin sheath on an axon

 Amyotrophic Lateral Sclerosis (ALS)- Neurodegenerative Disease that effects the neurons in the brain and spinal cord.
