Systema nervosum

Systema Nervosum or the Nervous System is a complex network of nerves and cells, known as neurons, that transmit signals between different parts of the body. It is essentially the body's electrical wiring and is responsible for controlling and coordinating body activities. It has two major parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).

Central Nervous System

The Central Nervous System is the main control center of the body. It consists of the brain and the spinal cord. The brain is the site of processing and command giving, while the spinal cord is the main pathway for information connecting the brain and peripheral nervous system.

Peripheral Nervous System

The Peripheral Nervous System is the network of nerves that connects the CNS to the rest of the body. It is divided into the Somatic Nervous System and the Autonomic Nervous System. The Somatic Nervous System is responsible for voluntary movement of the muscles and organs, while the Autonomic Nervous System is responsible for control of the bodily functions not consciously directed, such as breathing, heartbeat, and digestive processes.

Function

The primary function of the Systema Nervosum is to send signals from one cell to others, or from one part of the body to others. It also helps in coordinating the actions of the body and transmits signals between different parts of the body.

Disorders

There are many disorders of the Systema Nervosum, including Alzheimer's disease, Parkinson's disease, and Multiple sclerosis. These disorders can affect both the CNS and PNS, and can result in symptoms ranging from mild to severe.
