Document Summary
Functional classification of neurons: sensory neurons, or afferent neurons, receive information from sensory receptors, relay that information to the cns 2. Motor neurons, or efferent neurons: carry instructions away from cns, peripheral targets of these instructions called effectors, 3. Interneurons, or association neurons: located entirely within the cns, interconnect other neurons. Efferent motor subdivisions: somatic nervous system (sns, controls skeletal muscle, autonomic nervous system (ans, controls smooth and cardiac muscle, and glands, includes two parts, sympathetic division, parasympathetic division. Neural tissue: nervous or neural tissue includes two types of cells, neurons, basic functional units of nervous system, communicate with one another and with other cells, 2. Neuroglia: regulate environment around and support neurons, much more numerous than neurons, are able to divide (unlike most neurons) Motor neurons: total about half a million in number, somatic motor neurons, innervate skeletal muscle, visceral motor neurons, innervate cardiac muscle, smooth muscle, and glands.
