2023年11月3日 · The nervous system (NS) is structurally broken down into two divisions; Central nervous system (CNS) - consists of the brain and spinal cord; Peripheral nervous system (PNS) - gathers all neural tissue outside the CNS; Functionally, the nervous system can be categorized into three main areas: sensation, integration and response.

2024年4月2日 · The two main divisions of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS). What is a Neuron? Neurons are the basic unit of communication in the nervous system that transmits signals throughout the body.

2024年4月29日 · The structural classification, which includes all of the nervous system organs, has two subdivisions- the central nervous system and the peripheral nervous system. Central nervous system (CNS). The CNS consists of the brain and spinal cord, which occupy the dorsal body cavity and act as the integrating and command centers of the nervous system.

Among the cranial nerves, the trigeminal nerve has three pairs of divisions (tri– = “three”; –gemini = “twins”). Pain in the trigeminal nerve is called trigeminal neuralgia (neur– = “nerve”; –algia = “pain”). Sensory information originates from the external or internal environment.

Then you will look at the structural divisions of the nervous system by regions where the organs are located, and then the functional divisions by the specific functions achieved by the organs within it. Nervous tissue contains two basic types of cells: neurons and glial cells.

Anatomy and Physiology of the Nervous System High-Yield Notes by Osmosis. Detailed diagrams, vivid illustrations, and concise explanations.

The autonomic nervous system controls our internal organs and glands and is generally considered to be outside of our voluntary control. It can be further subdivided into the sympathetic and parasympathetic divisions (Figures 1.10). The sympathetic nervous system is often referred to as the fight or flight system, because it is involved in ...

The peripheral nervous system is subdivided into nerves, the autonomic system, and the somatic system. The autonomic nervous system is further subdivided into the parasympathetic and sympathetic nervous systems. The enteric nervous system is an independent subsystem of the peripheral nervous system.
