PATHOLOGY

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: -There are three branches to the ANS; the sympathetic nervous system, the parasympathetic nervous system, and the enteric nervous system. The sympathetic and parasympathetic divisions of the autonomic nervous system have the opposite effects on various systems.

Detailed explanation-3: -The somatic peripheral nervous system is a single neuron system with the motor neurons lying inside the brainstem or spinal cord and the sensory neurons lying in the dorsal root ganglia. The autonomic peripheral nervous system is a two neuron system with a neuron lying outside of the CNS in the autonomic ganglia.

Detailed explanation-4: -The central part of the ANS consists of centers within the brainstem and the spinal cord, while the peripheral part is made up of autonomic fibers and ganglia of the PNS. SNS centers are found within the thoracic and lumbar segments of the spinal cord, which is why it is also called the thoracolumbar division.

Detailed explanation-5: -Sympathetic nervous system: This system activates body processes that help you in times of need, especially times of stress or danger. Parasympathetic nervous system: This part of your autonomic nervous system does the opposite of your sympathetic nervous system. More items •15-Jun-2022
