nerve tissue

Nerve tissue is one of the four primary tissue types in the human body, responsible for communication and control. It is composed of two main cell types: neurons and neuroglial cells. Neurons are the basic units of the nervous system, specialized for receiving, processing, and transmitting information through electrical and chemical signals. They typically consist of a cell body (soma), dendrites that receive signals, and an axon that transmits signals away from the cell body. Neuroglial cells, often called "nerve glue," provide support to neurons and play roles in insulation, repair, and regulating the neuronal environment. Bundles of neuron fibers form nerves, which act as communication pathways throughout the body, enabling sensation, movement, and regulation of internal functions.123456
