Astrocytes
...  are the neuroglial cells of the central nervous system. They are the supporting structures for the main cell of the tissue, the neurons. It derived its name from its star-shaped appearance. The big cell body with its branching processes provides the characteristic appearance of the cell. When viewed under the microscope, you can easily distinguish them by their shape. Physiologically,  ...

Axon
...  leave the cell body. When the body needs them, the formation of collateral axons occur. These are axons resulting from the branching of the original axons. Schwann cells, on the other hand, are neuroglia, which form protective coverings in the form of myelin sheaths. The myelin sheaths insulate the axons and are responsible in stopping almost all electrical flow coming through the membrane  ...

Neurons
...  Neurons all have dendrites, enabling receptions and also an axon for the conduction of the nerve pulse. All these types give support (functional and structural) to the other types. Together with neuroglia, they compose the basic cell structure in the CNS, or the central nervous system. They are uniquely designed to respond to chemical releases and stimuli in an appropriate manner. They are  ...

Spinal Cord
...  the cells. Most of the parts in the spinal cord are made up with gray matter, and is also encompassed by white matter. The gray matter, which makes up the majority of the spinal cord is made up of neuroglia, unmyelinated association neurons and nerve cell bodies. The white matter on the other hand is composed of myelinated fibers that brings the motor and sensory neurons. At the core of the  ...

Pineal Gland
...  long. It starts to shrink when a person is 7 years old and continues to adulthood where it looks like a little fibrous tissue. The pineal gland is composed of specialized parenchymal cells and neuroglial cells. It gets innervated by the autonomic nervous system, and only that. Even if the pineal gland is located in the brain, it does not receive innervation from the brain. The superior  ...
