The brain, being the most complex organ of the body, controls every action and thought. It is divided into various functional units formed from brain cells that work together to respond to particular stimuli. The brain cells connect with other cells of the body to create communication routes for brain signals. As such, scientists are working to understand the complex organization of the brain with the help of tools that can tag and trace the circuits of the brain as well as finding out how different types of brain cells function. Therefore, the brain and the entire nervous system are crucial in providing information on disease symptoms to physicians and thus assist in diagnosis. This paper aims to discuss the composition of the neuroanatomy and its importance in the diagnosis of diseases.
Neuroanatomy involves the study of body anatomy and how the nervous system is organized. The nervous system differs depending on the animal’s symmetry and as such vertebrates have a segregated nervous system consisting of the internal structure of the brain and the spinal cord. This is connected to the rest of the body by a route of nerves known as the peripheral nervous system. The nervous system is divided into the central and peripheral whereby the central nervous system consists of the spinal cord, brain, and retina. The

It also represents a sense organ, such as an eye. The nervous system also contains neuroglial or glial cells which are not neurons and usually outnumber the neurons at a ratio of 10 to 1. The typical peripheral glial cells surrounding the axons are referred to as Schwann cells and are useful in myelination. The microglia, oligodendrocytes, and astrocytes form the central glia and are associated with the neuronal cell bodies. The gray matter of the central nervous system contains synapses, axons, dendrites, and neuronal cell
