Nervous tissue is a specialized type of tissue that makes up the nervous system, which includes the brain, spinal cord, and nerves. It is primarily composed of two main cell types: neurons and glial cells. Neurons are responsible for transmitting electrical signals throughout the body, allowing for communication between different parts of the nervous system. Glial cells support and protect neurons, playing essential roles in maintaining the overall health of nervous tissue. This tissue is crucial for various functions, including sensory perception, motor control, and cognitive processes. Nervous tissue enables the body to respond to stimuli and coordinate actions, making it vital for survival. Damage to nervous tissue can lead to serious conditions, affecting movement, sensation, and overall function.
