Nervous Tissue

Nervous tissue is a specialized type of tissue that is found in the nervous system. It is made up of two main types of cells: neurons and neuroglia. Neurons are responsible for transmitting electrical signals, while neuroglia support and protect the neurons. Together, they form the complex network that allows the nervous system to function.

Neurons

Neurons are the primary cells of the nervous system and are responsible for transmitting electrical signals. They have a unique structure that allows them to perform this function. A neuron consists of a cell body, dendrites, and an axon. The cell body contains the nucleus and other organelles, while the dendrites receive signals from other neurons. The axon, on the other hand, transmits signals to other neurons or to other cells in the body.

Neuroglia

Neuroglia, also known as glial cells, are the supporting cells of the nervous system. They provide support and protection for the neurons, as well as helping to maintain the overall function of the nervous system. There are several types of neuroglia, each with its own specific functions, such as providing insulation for neurons, removing debris, and regulating the chemical environment of the nervous system.

Functions of Nervous Tissue

Nervous tissue is responsible for a wide range of functions in the body, including sensory perception, motor coordination, and the regulation of bodily functions. It allows us to sense and respond to our environment, as well as controlling essential processes such as heart rate, digestion, and breathing.
