They are the cells that receive sensory information from the. Neurons, or nerve cell, are the main structural and functional units of the nervous system. The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
Structurally, neurons consist of three main components: The human nervous system is a network of specialised cells and tissues that includes the brain, spinal cord, and a complex network of peripheral nerves. At its core, the nervous system is a massive communication network.
But there is a third function that needs to be. Neurons, also referred to as neurones or nerve cells, are the basic building blocks of the brain and nervous system. The cell body contains the nucleus and other essential cellular components. Your nervous system uses nerve cells called neurons to send signals, or messages, all over your body.
The brain is contained within the cranial cavity of. These electrical signals travel among your brain, skin, organs,. It sends, receives, and interprets electrical and chemical signals throughout the body. The human nervous system is the series of cells and nerve tracts that conduct stimuli from sensory receptors in the periphery to receptors in the brain and spinal cord and then conduct.
The nervous system is involved in receiving information about the environment around us (sensory functions, sensation) and generating responses to that information (motor functions,. The central nervous system (cns) is the brain and spinal cord, and the peripheral nervous system (pns) is everything else (figure 1).
