What is a nerve innervation?
nerve innervation is a term used to describe nerve distribution throughout the body and into specific areas together with the supply of nerve pulses. Doctors study nerve innervation extensively at the Faculty of Medicine, often with the help of an autopsy in an anatomical laboratory, and are responsible for how every nerve in the body is distributed. Understanding nerve innervation is the key to the diagnosis and treatment of many health conditions, from the diagnosis of neurological problems to learning to prevent critical nerves during general surgery.
The nervous system begins with the brain that descends to the spinal cord. Nerves branch in all directions and lead to many different parts of the body. For example, the optical nerve innervates the eye and is a classic example of thick nerve innervation, which means that many nerves are grouped into a very small area. Nerves can be voluntary or involuntary, depending on where they come and what to go on. Voluntary nerves can be controlled by the conscious thoughts of a person while involuntary nerves are part of aUtonomous body processes that keep the body functioning.
Hands are another area of dense nerve innervation, reflecting highly specialized hands and need for accurate control. The nerves enter the wrist hand and distribute through the palm to the fingers, allowing people to control their hands to perform a range of tasks, from grasping the fork to neurosurgery. Dense innervation also allows very accurate and detailed sensory information about returning to the brain.
Sometimes nerve innervation can lead along surprising roads. For example, the vagus nerves innervate many visceral organs, despite the fact that the branches of the nerves along the spinal cord are much closer to the viscera than the vagus nerve. Vagus nerves provides involuntary innervation, keeps the abdominal organs at work on different tasks, even if one sleeps.
Knowing which nerve innovates which part of the body can be important for neurologists because they can use informationabout the body to narrow the areas of damage along the nervous system. For example, doctors can find an accurate area of damage in the spinal cord in case of paralysis by determining which area of the body is paralyzed. Brain damage can also cause nerve innervation problems, as in the case of people who experience damage to their brain steries, which causes them not to breathe separately.
