The body is made up of four different types of tissues, which are listed below. A type of tissue is not specific to a single organ, and all types of tissue, like some types of cells, can be found in most organs. Nerve cells and circulating blood cells, for example, can be found in almost any organ.
Oral tissues are meticulously organized so that they can conduct organ functions in unison. This is analogous to an orchestra, which consists of different musical instruments, each of which is situated in a specific location and contributes to the creation of harmony at precisely the right time. Tissues and cells, including musical instruments that are mixed and matched in different forms of musical groups, are found in a variety of organs and contribute to the function of the organ and the preservation of homeostasis.
The four different types of tissues are all made up of cells and extracellular materials. Tissues, on the other hand, include different cell types and different percentage compositions of cells and extracellular materials. Figure 1 shows how tissues fit into the body’s part hierarchy.

How to neuron step by step for beginners !

Despite the complexity of the nervous system, nerve tissue contains only two types of cells. The neuron is the real nerve cell. It is the structural unit of the nervous system and the “conducting” cell that transmits impulses. Neuroglia, also known as glial cells, is the other type of cell. “Neuroglia” simply means “nerve glue.” These nonconductive cells act as a support mechanism for neurons. They are a form of “connective tissue” that is specific to the nervous system.
Neurons, also known as nerve cells, conduct nerve impulses to carry out the functions of the nervous system. They are amitotic and highly specialized. Since neurons do not go through mitosis, this means that if a neuron is killed, it cannot be replaced. The configuration of a typical neuron is depicted in the illustration below.
The cell body is identical to other types of cells in several respects. It comprises several of the usual cytoplasmic organelles and has a nucleus with at least one nucleolus. However, it is devoid of centrioles. Since centrioles are involved in cell division, the absence of these organelles in neurons is consistent with the cell’s amitotic existence.

One of the four main types of tissue is nervous tissue. It is specialized tissue that can be used in both the central and peripheral nervous systems. It is made up of neurons and neuroglia, which are helping cells. The nervous system is in charge of regulating the body and interacting with its different parts. Neurons and neuroglia are two types of cells present in nervous tissue.
Dendrites are responsible for reacting to stimuli and receiving incoming signals before passing them on to the cell body. The axons are in charge of transmitting impulses from the cell body over long distances. The neuron’s cell body functions as a factory. It comprises specialized organelles such as the nucleus, granules, and Nissl bodies, as well as producing all proteins.
The parts of a neuron are depicted in this illustration. Dendrites absorb incoming signals, while axons carry signals away from the cell body of the neuron. The axon is surrounded and insulated by the myelin sheath.
Schwann cells are neuroglia cells that promote neuronal activity by increasing the speed of impulse propagation in the peripheral nervous system. The medullary sheath lies underneath the Schwann cells. The nodes of Ranvier disturb the medullary sheath at regular intervals.
