Anatomy Exam 4

With the help of the endocrine system, helps to keep controlled conditions within limits that maintain health and helps to maintain homeostasis; is responsible for all our behaviors, memories, and movements

The branch of medical science that deals with the normal functioning and disorders of the nervous system

Consists of the brain and the spinal cord

Consists of the 12 pairs of cranial nerves, 31pairs of spinal nerves, ganglia, enteric plexuses in small intestine, and sensory receptors in skin; connects CNS to muscles, glands and all sensory receptors; contains both sensory and motor fibers

Located outside the brain and spinal cord, are small masses of nervous tissue, containing primarily cell bodies of neurons

Help regulate the digestive system; extensive network of neurons in the walls of digestive tract organs (ex: the G.I. tract)

Are either parts of neurons or specialized cells that monitor changes in the internal or external environment; ex: dendrites of neurons or cells (taste buds)

Sensory, integrative, and motor

To sense changes in the internal and external environment through sensory receptors; sensory (afferent) neurons serve this function; 2 types-somatic sensory receptors and visceral receptors

Detect info about outside world/our position in the world; 2 types: external receptors and proprioceptors

Type of somatic sensory receptors that receive info about external environment (touch, temp, pressure, sight, smell, and hearing)

Monitors the position and movement of skeletal muscles and joints

Monitors the activities of the digestive, respiratory, cardiovascular, urinary, reproductive systems and provides sensations of taste, deep pressure, and pain

To analyze the sensory information, store some aspects, and make decisions regarding appropriate behaviors; association or interneurons serve this function

Is to respond to stimuli by initiating action; motor (efferent) neurons serve this function
