Nervous tissue is one of four major classes of tissues. It is specialized tissue found in the central nervous system and the peripheral nervous system. It consists of neurons and supporting cells called neuroglia. The nervous system is responsible for the control of the body and the communication among its parts.
What type of tissue is in the nervous system?
Structure. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Four types of neuroglia found in the CNS are astrocytes, microglial cells, ependymal cells, and oligodendrocytes.
Is nervous tissue classified as connective tissue?
Connective tissue is one of the many basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. In embryology it develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system.
What is nerve tissue called?
Nervous tissue is found in the brain, spinal cord, and nerves. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. … These cells have three principal parts: the dendrites, the cell body, and one axon.
Is nervous tissue a primary tissue?
These categories are epithelial, connective, muscle, and nervous. The primary tissue types work together to contribute to the overall health and maintenance of the human body.
How is nervous tissue different from other tissues?
Nervous tissue the most complex of the four basic tissues, is composed of nerve cells, the neurons and supporting cells, the neuroglia. Unlike other basic tissues, the nervous tissue almost lacks intercellular substance.
What are the 3 types of nervous tissue?
4.4B: Types of Nervous Tissue
- Microglial Cells.
- Ependymal Cells.
- Satellite Cells.
- Schwann Cells.
What are the 4 tissue types?
There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
Is epithelium a connective tissue?
Epithelial tissue is found in various organs like skin, buccal cavity, the lining of blood vessels, body cavities, glands, and their ducts. Connective tissue is the tissue that forms the bones, cartilages, adipose tissue, reticular tissue, and the blood.
Where nervous tissue is not found?
Tendons are the connective tissue, which join skeletal muscles to bones, hence nervous tissue is absent is them. Nervous tissue is specialised to transmit messages within our body. It contains highly specialised unit cells called nerve cells or neurons.
Which of the following is composed of nervous tissue?
Brain, spinal cord and nerves, all are composed of the nervous tissue.
What is the origin of nervous tissue?
Origin of Neural Tissue:
The neural tissue in general develops from the ectoderm of the embryo, but the microgliocytes (to be described ahead) arise from the mesoderm of the embryo.
Are nerves made of neurons?
A nerve is a bundle of fibers that receives and sends messages between the body and the brain. The messages are sent by chemical and electrical changes in the cells, technically called neurons, that make up the nerves.
What type of tissue supports epithelium?
The type of tissue that supports epithelium is known as basement membrane.
What are connective tissues?
Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage. They occur throughout the body. … Numerous cell types are found in connective tissue.
Which tissue is an excitable tissue?
Neurons are identified as excitable cells because they have the ability to be electrically excited resulting in the generation of action potentials. Other examples of excitable cells are skeletal, smooth, and cardiac muscle cells (Chapter 5) and secretory cells of the pancreas.
