MEDIAN NERVES Meaning and
Definition
-
The median nerves, in anatomical terms, refer to a pair of nerves that are part of the peripheral nervous system. There is one median nerve in each arm, arising from the brachial plexus, a network of nerves formed by the lower cervical and upper thoracic spinal nerves. The median nerves run down the forearm and supply innervation to various muscles and skin areas of the hand.
Functionally, the median nerves play a crucial role in providing motor and sensory signals to the hand and fingers. They are responsible for controlling the movement of certain muscles in the forearm and hand, allowing for fine motor skills such as gripping and manipulating objects. Additionally, these nerves transmit sensory information, enabling the perception of touch, pain, temperature, and pressure in specific regions of the hand.
Pathologies or injuries affecting the median nerves can lead to a condition known as median nerve entrapment or compression, like carpal tunnel syndrome. This condition can occur when the median nerve becomes compressed or irritated at the wrist joint, resulting in symptoms such as pain, tingling, numbness, or weakness in the hand and fingers.
In conclusion, the median nerves are vital structures within the peripheral nervous system that facilitate motor control and sensory perception in the hand. Their proper functioning is crucial for everyday activities and maintaining hand dexterity.

Etymology of MEDIAN NERVES
The word "median" comes from the Latin word "medius", which means "middle". This is because the median nerve is situated in the middle of the forearm and hand. The term "nerve" originated from the Latin word "nervus", meaning "sinew" or "ligament", referring to the tough, fibrous structure of nerves. Together, the term "median nerves" is derived from Latin roots and describes the nerves located in the middle of the arm.
