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.
The brain and spinal cord are part of the C.N.S.(Central Nervous System)
The nerves from senses -> brain -> motor neuron -> muscle are part of the P.N.S. (Peripheral Nervous System)The components of the nervous system are the following; the brain, spinal cord and the 12 cranial nerves.
central nervous system and peripheral nervous system
The components of the nervous system involved in skeletal movements are the hemolymph A31.
sympathetic nervous system.
The central nervous system (brain, spinal cord) and the peripheral nervous system (nerves).
The Sympathetic and Parasympathetic nervous systems are the divisions of the ANS. The sympathetic is where "fight or flight" comes in, and the parasympathetic is what calms us down afterward -- they work to balance each other.
PNS means peripheral nervous system. It has two main components: the autonomic nervous system and the somatic, or voluntary nervous system. The autonomic nervous system also contains two parts: the sympathetic nervous system and the parasympathetic nervous system.
The peripheral nervous system is divided into motor and sensory systems. The peripheral nervous system is also divided into the somatic nervous system and the autonomic nervous system.
The Brain & the Spinal Cord are the 2 major components of the central nervous system.
The brainstem, located at the base of the brain, plays a key role in controlling the autonomic nervous system, which regulates involuntary functions like heart rate and breathing. Specifically, regions such as the medulla oblongata and the pons are crucial for coordinating these functions.
Since the brain and spinal cord comprise the Central Nervous System (CNS) everything else is in the Peripheral Nervous System. Sensory neurons, motor neurons, and interneurons are all components.
The components that make up central nervous system consists of two main parts. The central nervous system is made up of the brain and the spinal cord.
CNS = central nervous system (brain and spinal cord)PNS = peripheral nervous system (that part of the nervous system that extends outside the central nervous system)
