What are the tissues 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. Two types of neuroglia found in the PNS are satellite cells and Schwann cells.
What are the 4 main organs tissues of the nervous systems?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
Is nervous tissue all over the body?
It regulates your body’s systems and allows you to experience your environment. A vast network of nerves sends electrical signals to and from other cells, glands, and muscles all over your body.
What is a nervous tissue composed of?
Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.” There are six types of neuroglia. Four are found in the central nervous system, while two are found in the peripheral nervous system.
What is a nervous tissue?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. 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 connective tissue?
Connective tissue is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system.
What are some examples of nervous tissue?
Examples of nervous tissue include the brain, spinal cord, and the peripheral nervous system. All of these systems regulate and control various functions in the body.
What is the basic structure of nervous tissue?
The basic unit of structure of nervous tissue is the neuron, consisting of a nerve cell body and several processes: dendrites , which carry impulses toward the nerve cell body, and axons, which carry impulses away from the cell body.
What are the differences between nervous and muscle tissue?
The key difference between muscular tissue and nervous tissue is that the muscular tissue is a tissue specialized for contraction , while the nervous tissue is a tissue specialized for communication. Epithelial tissue, muscle tissue, nervous tissue, and connective tissue are four types of tissues present in the animal body.
What are the main cells found in nervous tissue?
Nervous tissue consists of two main types of cells: neurons and neuroglia . Nerve cells, or neurones (also written ‘neurons’) transmit nerve impulses that move information around the body. Neuroglia are also known simply as ‘glia’ and have various functions in support of nerve cells but do not transmit nerve impulses themselves.
