describe the cell categories of nervous tissue and describe the organization of nervous tissue in the central nervous system versus the peripheral nervous system. Solution There are two types of cells are found in nervous tissue. First one is nerve cells, also known as neurons, composed of axons, cell body and dendrites. This transmit nerve impulses and pass information around the body. There are several types of neurons, including motor neurones, sensory neurones and relay neurones. The other type of cell is neuroglial cells, also known as glia. Glia do not transmit nerve impulses themselves. These are supporting cells and and perform various functios in support of nerve cells. They form packaging media between nerve cells in brain and spinal chord. They provide nutrition to neurons. Axons and Nissl\'s granules are absent in glia. There are many types of glia for example ependymal cells, microglial cells, astrocytes etc. There are four types of nervous tissue. 1. White matter 2. Gray matter 3. Ganglion 4. nerve. White matter and gray matter tissues are found in central nervous system and Ganglion and nerve are found in peripheral nervous system. 1. Gray matter: This is compose of cell bodiesdendrites, unmyelinated axons, protoplasmic astrocytes (astrocyte subtype), satellite oligodendrocytes (non-myelinating oligodendrocyte subtype), microglia, and very few myelinated axons. 2. White matter : is composed of myelinated axons, fibrous astrocytes, myelinating oligodendrocytes, and microglia. 3. Ganglion: This is composed of cell bodies, dendrites, and satellite glial cells. 4. Nerves: These are composed of myelinated and unmyelinated axons, Schwann cells surrounded by connective tissue..

Solution
There are two types of cells are found in nervous tissue. First one is nerve cells, also known as
neurons, composed of axons, cell body and dendrites. This transmit nerve impulses and pass
information around the body. There are several types of neurons, including motor neurones,
sensory neurones and relay neurones. The other type of cell is neuroglial cells, also known as
glia. Glia do not transmit nerve impulses themselves. These are supporting cells and and perform
various functios in support of nerve cells. They form packaging media between nerve cells in
brain and spinal chord. They provide nutrition to neurons. Axons and Nissl's granules are absent
in glia. There are many types of glia for example ependymal cells, microglial cells, astrocytes
etc.
There are four types of nervous tissue. 1. White matter 2. Gray matter 3. Ganglion 4. nerve.
White matter and gray matter tissues are found in central nervous system and Ganglion and
nerve are found in peripheral nervous system.
1. Gray matter: This is compose of cell bodiesdendrites, unmyelinated axons, protoplasmic
astrocytes (astrocyte subtype), satellite oligodendrocytes (non-myelinating oligodendrocyte
subtype), microglia, and very few myelinated axons.
2. White matter : is composed of myelinated axons, fibrous astrocytes, myelinating
oligodendrocytes, and microglia.
3. Ganglion: This is composed of cell bodies, dendrites, and satellite glial cells.
4. Nerves: These are composed of myelinated and unmyelinated axons, Schwann cells
surrounded by connective tissue.
