Introduction
The nervous system is a sophisticated system with a group of specialized cells called
neurons and nerves that convey signals between different body parts. Anatomically, it is made up
of two components that include the central nervous system and the peripheral nervous system. The

neurons, and nerves that join to one another and the CNS. In addition to these two principal
components, the nervous system also includes ears, eyes, sensory organs of taste and smell and
sensory receptors in various body parts like skin, joints, and muscles (Xilouri & Stefanis, 2010).
The nervous system is vulnerable to infections and disorders such as structural disorders,
functional disorders, and vascular disorders. Thus, this paper aims to highlight three major nervous
disorders; one that is related to the eye, another related to the ear, and the last one that is related to
the general nervous system.
Optic Neuritis
Optic neuritis is a neuro-ophthalmic disorder that is characterized by an inflammation that
damages the optic nerve. The optic nerves have a role of conveying visual information from the
eye to the head. The disorder is associated with a demyelinating condition that results in the loss
of the protective myelin sheath around the neuron. It is also associated with multiple sclerosis
disorder that leads to the damage and inflammation of the brain and spinal cord nerves. The
multiple sclerosis disorder is characterized by the immune system attacking the myelin sheath that
covers the brain and spinal cord nerves, leadi...
