By SNS do you mean sensory nervous system? Spinal nerves are part of the Central nervous system (CNS) which also includes the brain.
Sympathetic nervous system .
The division of the autonomic nervous system that arises from spinal nerves T1 to L3 is the sympathetic division. This division is responsible for controlling involuntary body functions.
The nervous system is divided into: - The central nervous system (CNS) : Encephalon, diencephalon, mesencephalon, pons, medulla, spinal cord, cerebellum. - The peripheral nervous system (PNS) : Roots, spinal nerves, plexi, peripheral nerves and neuromuscular junction. - The autonomic nervous system (ANS) : Sympathetic and Parasympathetic
The Brain and Spinal cord form the Central Nervous System. The Peripheral Nervous System comprises the nerves that ultimately feed into the CNS and is divided into the Sympathetic and Parasympathetic Nervous Systems.
for the nerves the peripheral nervous system, for your brain and spinal cord the cental nervous system.
i think that it is the sympathetic nervous system
sympathetic division of the autonomic nervous system
Cranial nerves and spinal nerves.
Peripheral Nervous System (PNS) original answer by btbchris
the spinal cord
Peripheral nervous system consist of all of the Cranial nerves and Spinal nerves. This division is Anatomical and not Physiological.
The nervous system is composed of both central (brain and spinal cord) and peripheral components, with the latter having both somatic and autonomic (parasympathetic and sympathetic) subdivisions.
