What are the general characteristics of nervous tissue?

Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Two main classes of cells make up nervous tissue: the neuron and neuroglia (Figure 4.5.

What is the structure of nervous tissue?

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 is the histology of nervous tissue?

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 electrically active and release chemical signals to target cells. Glial cells, or glia, are known to play a supporting role for nervous tissue.

What are the 3 types of nervous tissue?

4.4B: Types of Nervous Tissue

• Neuroglia.
• Astrocytes.
• Microglial Cells.
• Ependymal Cells.
• Oligodendrocytes.
• Satellite Cells.
• Schwann Cells.
• Neurons.

What are the two major characteristics of nervous tissue?

Integration and communication are the two major functions of nervous tissue. Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses.

What is the main characteristic of nervous tissue quizlet?

What characteristics of nervous tissue makes for a quick response to detect environmental changes that impact the body? excitability characteristic of nervous tissue- allows for generation of nerve impulses. You just studied 120 terms!

How does nervous tissue explain the structure of the neuron with a diagram?

Nervous or the nerve tissue is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons.

What is a nervous tissue explain the function and structure of a neuron with a diagram?

Answer: Neurons are the structural units of the nervous tissue. These space cells are specialised for the conduction of impulse is over great distances at great speed. All neurones have a cell body called cyton, several dendrites, and an axon. Cyton contains nucleus and many hair like projections called dendrons.

Is nerve CNS or PNS?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

What are the 3 main components of the nervous system?

The three main components of nervous system are brain, spinal cord and nerves.

What are the 2 types of nervous tissue?

Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.

What do you need to know about nervous tissue?

Histology – Nervous tissue Description: This is a section of the spinal cord revealing the cell body of one of the large alpha motor neurons. Note the initial portions of the dendrites and axon that arise from the neuronal body. Scattered around the neuron are many neuroglial cells, which in addition to neurons are the other type…

What are the main objectives of neurohistology I?

Neurohistology I: Cells and General Features Overall Objectives: to understand the histological components of nervous tissue; to recognize the morphological features of neurons; and to differentiate myelinated from non-myelinated axons I. Basic Organization:

Are there neuroglial cells in the nervous tissue?

Scattered around the neuron are many neuroglial cells, which in addition to neurons are the other type of cell in nervous tissue. Neurons are the electrical communication and circuit board cells of the body. The neuroglial cells do not generate or conduct nerve impulses, but they have important supportive roles for the neurons.

Is it possible to cover the nervous system in one laboratory?

The nervous system is extraordinarily complex, and it is therefore impossible to cover it in its entirety in a single laboratory.
