Introduction
According to Gutmann et al. (2017) neurofibromatosis is a group of three conditions whereby tumors grow in the nervous system. These conditions are neurofibromatosis type I (NF1), neurofibromatosis type II (NF2), and schwannomatosis. It is considered to be a genetic disorder of the nervous system. Neurofibromatosis mainly affects the development and growth of nerve cell tissue. The tumors can develop anywhere in the nervous systems including spinal cord, brain, and nerves. These tumors are mostly noncancerous, however, there have been instances when they do become cancerous. The most common condition is NF1. Schwannomatosis is the most recent and it is a rare type of neurofibromatosis. Little is known about schwannomatosis.
NF1 manifests at birth or in early childhood. It is characterized by multiple café-au-lait (light brown) spots that are concentrated in the groin and underarms (Gutmann et al., 2017). It is also manifested by benign tumors under the skin. Scoliosis may be present. NF2 might appear during childhood, adolescence, or in early adulthood. NF2 is portrayed by benign tumors of the nerves that will transmit sound impulses and balance signals from the inner ears to the brain. The tumors will mostly affect both the right and left auditory nerves.
Normal Anatomy of The Nervous System
The central nervous system (CNS) consists of the brain and spinal cord. The brain is charged with controlling most of the body functions including movements, awareness, thoughts, sensations, memory, and speech. The spinal cord is connected to the brain at the brainstem. It is covered by vertebrae of the spine. The nerves exit the spinal cord on to both sides of the body. The spinal cord is charged with carrying signals back and forth from between the nerves in the body and the brain (Anderson & Gutmann, 2015).
The part of the nervous system that is outside the CNS is referred to as the peripheral nervous systems (PNS). PNS is made up of nerves that send and receive signals from the CNS. It is divided into the autonomic nervous system and the somatic nervous system. The autonomic nervous system is charged with controlling involuntary functions that...
