Nervous tissue is a specialized form of tissue which is responsible for the conduction of electrical impulses between all parts of the body. It consists of two types of cells: the neurons and the glial cells. Nervous tissue is found in the brain and nerves. The human body is made up of the following organ systems:
Sri K.
The body has four basic types of tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Each type of tissue has a specific role in the body. Epithelial tissue covers the surfaces of the body, both inside and outside. It forms the outer layer of the skin and lines the organs and cavities within the body. Epithelial tissue protects the underlying structures, regulates the exchange of materials, and secretes substances. Connective tissue provides support and structure to the body. It includes various types of tissue such as bone, cartilage, adipose tissue, and blood. Connective tissue connects and anchors different body parts, provides cushioning and protection, and transports nutrients and waste products. Muscle tissue is responsible for movement in the body. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscle is attached to bones and allows voluntary movements. Cardiac muscle is found in the heart and is responsible for pumping blood. Smooth muscle is found in the walls of organs and blood vessels and controls involuntary movements. Nervous tissue is involved in communication and coordination within the body. It consists of neurons and supporting cells. Nervous tissue receives and transmits signals, allowing the body to respond to stimuli and coordinate various functions.

PART 4. NERVOUS TISSUE Nerve cells, or neurons, are difficult to observe under the microscope since they are very thin and elongated fibers that may reach up to a meter in length. They are the main functional cells of the nervous system. Other support cells are called neuroglial cells, which are more numerous. Nervous tissue functions for communication within the body. This communication requires the initiation, transmission, and interpretation of a nerve impulse. Many neurons are packaged together to form a nerve. Nerves form a network that coordinates every part of the body. The round trip that an impulse makes from the point of origin (such as the tip of your finger) to the central nervous system (spinal cord and brain) and back again is termed the reflex arc.
