The function of nervous tissue is to transmit and receive external and internal stimuli. Consisting of two basic types of cells, neurons and glial cells, nervous tissue represents a fundamental aspect of living organisms and can be considered the seat of response to stimuli. Signals from the internal or external environment are received by the neurons and then transmitted as electrical impulses to muscles, glands, the central nervous system or other neurons.Know More
The glial cells in nervous tissue are the protective cells. They make up about 90 percent of nervous tissue and surround many of the processes that occur there. Their function is to provide support, nutrition and insulation for the neurons. The glia that are found within the central nervous system, which consists of the brain and spinal cord, are called neuroglia.
There are three types of neurons: motor neurons, sensory neurons and interneurons. The motor neurons move the action potential from the central nervous system to the effector organs, such as muscles or glands. The sensory neurons function in the opposite manner, moving the action potential from the sensory organs to the central nervous system. The interneurons act as connectors between neurons.
Overall, neurons are responsible for the reception, propagation and conduction of nerve impulses. The sensory and motor neurons are found mostly outside of the brain and spinal cord, while the interneurons are found entirely within the central nervous system.Learn more about Nerves
The central nervous system, composed of the brain, spinal cord and an extensive neuron network, serves as the control center for all bodily functions. It functions as the transmitter and receiver as well as the pathway for information flow and determines how the body responds to changes in its internal and external environment.Full Answer >
The nervous system functions to process input from sensory receptors, transfer and interpret impulses and to control the functions of body's muscles and organs. The nervous system is comprised of nerves made up of specialized cells known as neurons.Full Answer >
The basic unit of the nervous system is the neuron, or nerve cell. Neurons are distinguished from other cells by their ability to communicate with other neurons through synaptic transmission and form highly structured communication networks. Neurons are electrically excitable cells that receive, process and transmit information using electrical and chemical signals.Full Answer >
The purpose of the central nervous system is to receive information from the sensory organs and process this information to initiate some type of effect. The central nervous system consists of the brain and spinal cord.Full Answer >
