Nervous System Test (veterinary Science)

Analyze the differences between the somatic and autonomic divisions of the peripheral nervous system. Make sure you pull up the rubric to help you answer the question.

Peripheral Nervous System (PNS) is made up of nerves that attach to Center Nervous System (CNS)-arms, legs, hands, and feet. PNS also has both Somatic nervous system and autonomic nervous system. Somatic is split of the PNS that controls the body's skeletal muscles, it also responsible for contraction voluntarily muscle soft smooth and it also helps with hearing, touching, and feeling. it is made up of spinal nerves, consists of sensory neurons and motor neurons, and pairs of spinal nerves and it is coming from spinal cord. Sympathetic function is part of autonomic nervous system that move body to deal with quick threats like fight or flight body will gets activated when scared. Autonomic division of the part of PNS that controls the glands and the muscles of the internal organs. it is made up of nerves that connect the CNS/to organs like a heart, stomach, intestines, and glands. It is controlled by the hypothalamus. This is correct
