AP PSYCHOLOGY

Detailed explanation-1: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Detailed explanation-2: -The autonomic nervous system, also called the visceral efferent nervous system, supplies motor impulses to cardiac muscle, to smooth muscle, and to glandular epithelium. It is further subdivided into sympathetic and parasympathetic divisions.

Detailed explanation-3: -The autonomic nervous system has two parts, the sympathetic division and the parasympathetic division. Many visceral organs are supplied with fibers from both divisions.

Detailed explanation-4: -In which way are the sympathetic and parasympathetic divisions of the autonomic system similar? Both utilize two neurons per message. In both, the preganglionic neuron is shorter than the postganglionic neuron.

Detailed explanation-5: -Parasympathetic nervous system consists of the cranial and the sacral components (Purkayastha et al., 2013). The cell bodies of parasympathetic preganglionic fibers are located in the ganglia associated with oculomotor, facial, glossopharyngeal and vagus nerves and in the spinal cord segments S2–S4.
