Document Summary
Nervous system i: organization of the nervous system including peripheral nervous system both motor and sensory. Chapter 11: sensory input: monitor changes inside and outside the body be. Integration: nervous system processes and interprets sensory input and decides what should done at the moment: motor input: the nervous system activates effector organs- the muscls and glands to cause a response, called motor output. Central nervous system (cns: consists of the brain and spinal cord, control center for the nervous system past. Interprets sensory input and dictates motor output based on reflexes, current conditions, and experiences. Somatic sensory fibers: convey impulses from the skin, skeletal muscles and joints. Visceral sensory fibers: transmit impulses from the visceral organs. Somatic nervous system: voluntary nervous system (consciously control our skeletal muscles) Autonomic nervous system: involuntary nervous system (pumping of heart, movement of food in digestive tracts: neuron, neuroglia and synapse anatomy and classifications. Chapter 11 neuron: sensing, effecting (controlling muscles, regulating glandular secretions)
