Neural tissue is formed by the
Cells of nervous tissue. Nervous tissue is the main component of the two parts of the nervous system; the brain and spinal cord of the central nervous system (CNS), and the branching peripheral nerves of the peripheral nervous system (PNS), which regulates and controls bodily functions and activity.n the central nervous system (CNS), the tissue types found are grey matter and white matter. In the peripheral nervous system (PNS), the tissue types are nerves and ganglia. The tissue is categorized by its neuronal and neuroglial components. Structure [edit]. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Typically, nervous tissue is categorized into four types of tissue. In the central nervous system (CNS), the tissue types found are grey matter and white matter.In the peripheral nervous system (PNS), the tissue types are nerves and ganglia.The tissue is categorized by its neuronal and neuroglial components.n the central nervous system (CNS), the tissue types found are grey matter and white matter.

Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the conducting cell that transmits impulses and the structural unit of the nervous system.The other type of cell is neuroglia, or glial, cell.erve Tissue.

The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans, (animals more complex than the sponge) produce two or three primary germ layers.astrulation of a diploblast: The formation of germ layers from a (1) blastula to a (2) gastrula. Some of the ectoderm cells (orange) move inward forming the endoderm (red). Ectoderm. Ectoderm is one of the three primary germ layers in the very early embryo. The other two layers are the mesoderm (middle layer) and endoderm (most proximal layer), with the ectoderm as the most exterior (or distal) layer.It emerges and originates from the outer layer of germ cells.ctoderm.

Embryonic Development of the Neural Tube: The neural tube is the embryonic structure that ultimately forms the brain and spinal cord. It is formed in a process called neurulation, in primary and secondary neurulation processes.In mice, primary neurulation prevails in the rostral sections of the embryo, while secondary neurulation occurs in the caudal section.mbryonic Development of the Neural Tube: The neural tube is the embryonic structure that ultimately forms the brain and spinal cord.

Ependymal cells are found in the Central Nervous System (CNS), that is in the tissues of the Brain and Spinal Cord. : : 1  Protection: Forms lining of the ventricles of the brain and central canal of the spinal cord.icroglial cells are sometimes known simply as microglia and are found in the Central Nervous System (CNS), that is in the tissues of the Brain and Spinal Cord. : Microglia are small glial cells. : 1  Protects CNS neurons from disease 2  -. e.g. by clearing away debris and dead cells. Astroglial cells, also known as astrocytes are found throughout the Central Nervous System (CNS), that is in the tissues of the Brain and Spinal Cord. : An astrocyte is a star-shaped cell that has many processes extending from its cell body into the surrounding network of nerve fibres.icroglial cells are sometimes known simply as microglia and are found in the Central Nervous System (CNS), that is in the tissues of the Brain and Spinal Cord. : Microglia are small glial cells. : 1  Protects CNS neurons from disease 2  -. e.g. by clearing away debris and dead cells. Nervous Tissue: Response to Injury Nervous When a nerve is cut, either healing or permanent interruption of the neural pathways occurs. The final outcome depends on the severity of the injury and on its treatment.Several degenerative changes result when a nerve is cut.ervous Tissue: Response to Injury Nervous When a nerve is cut, either healing or permanent interruption of the neural pathways occurs.
