Question

Name the tissue present in the brain.

Answer 1

Hint: Tissues are collections of cells with a similar structure that work together to perform a specific function. Tissue is derived from an old French verb that means "to weave." Animal tissues are classified into four types: connective, muscle, nervous, and epithelial.

Complete answer:
Tissues are collections of similar cells that serve a common purpose. Epithelial, muscle, connective, and nervous tissue are the four basic types of tissue. Each tissue type serves a specific function in the body: Epithelium lines body cavities and covers the body's surface.

The term "nervous tissue" refers to groups of organized cells in the nervous system, which is the organ system that controls the body's movements, sends and carries signals to and from different parts of the body, and controls bodily functions such as digestion.

Neurons and neuroglia are the two main types of nerve tissue. Neurons, or nerves, transmit electrical impulses, whereas neuroglia do not; however, neuroglia perform a variety of other functions, including supporting and protecting neurons.

The nervous system is made up of nerve tissue. The nervous system is divided into several subsystems that overlap. The brain and spinal cord comprise the central nervous system (CNS), which coordinates information from all areas of the body and sends nerve impulses that control all bodily movements.

The peripheral nervous system (PNS) is made up of peripheral nerves that branch out all over the body. It connects the CNS to the rest of the body and is directly responsible for controlling movement of specific body parts; for example, just before arm movement, the CNS sends nerve impulses to the PNS nerves in the arm, causing the arm to move.

Thus, the tissue present in the brain is called nervous tissue.

Note: The function of nervous tissue is to form the nervous system's communication network by conducting electric signals across the tissue. Grey matter, which contains synapses in the CNS, is important for information processing. White matter in the CNS connects and facilitates nerve impulses between grey matter areas by containing myelinated axons.
