This is part of the section about the structure and function of different tissue types, which is related to the section about histology and cells incl. Nervous tissue consists of two main types of cells: More information about both of these types of cells follows below: They transmit electrical nerve impulses thereby moving information around the body.
Adorable animal families that will make you "aww" Nervous tissue has two main functions: Tissue in the central nervous system can be found in the brain and spinal chord. The peripheral nervous system is made up of all nerves and related tissue outside of these areas, and it gathers signals from all parts of the body and sends them to the central nervous system.
Signals from this tissue also cause muscle contractions. Neurons and glial cells make up nervous tissue. Humans have billions of neurons, in varying size, in their bodies.
Nerve processes are made of cytoplasm and resemble thin fingers. They extend outward from the neuron and are responsible for transmitting signals both to the neuron and away from it. There are two types of nerve processes: Axons carry messages away from the neuron and dendrites transmit signals to the neuron.
Together, axons and dendrites form nerves. Ad Glial cells — called neuroglia when located in the central nervous system — are often found in bunches around neurons in both the central and peripheral nervous systems and are smaller than neurons.
Glial cells have a special function when surrounding axons, though they do not transmit neurological signals.
Called Schwann cellsthese special glial cells provide the neurons of the nervous tissue with support, nutrition, and protection against bacteria. They hold the neurons together. Other types of glial cells include microglia and oligodendrocytes. Microglia help repair damage to the neurons, while oligodendrocytes support the axons.Nov 09, · Nervous tissue is compiled of one of four vertebrate tissues.
The main component of the nervous system is the brain, spinal cord, and the nerves. The nervous system regulates and controls body function.
The nervous tissue is composed of neurons, neuroglia cells and provides nutrients to . Nervous tissue is composed of two types of cells, neurons and glial cells. Neurons are the primary type of cell that most anyone associates with the nervous system.
They are responsible for the computation and communication that the nervous system provides. Nervous tissue makes up the different parts of our nervous system. It allows us to receive stimuli and process the information. Learn more about this tissue and take a short quiz at the end.
Nervous Tissue Definition.
Nervous tissue is the term for 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 the different parts of the body, and has a role in controlling bodily functions such as digestion.
Nervous tissue is one of four major classes of tissues and makes up the central nervous system and the peripheral nervous system. Integration and communication are the two major functions of nervous tissue. Nervous tissue is found in peripheral nerves throughout the body and in the organs of the central nervous system, the brain and spinal cord.
Nerve tissue is composed of neurons, which are specialized cells able to react to stimuli by sending a signal down a long strand of cell known as an axon.
