NERVUS DIGITALIS VOLARIS COMMUNIS Meaning and
Definition
-
The nervus digitalis volaris communis, also known as the common digital volar nerve, is a specific branch of the median nerve in the human body. The median nerve is one of the major nerves in the upper limb, originating from the brachial plexus and extending down the arm and forearm. It is responsible for innervating various muscles and conducting sensory signals from the hand.
The nervus digitalis volaris communis refers to the part of the median nerve that supplies innervation to the palmar aspect of the thumb, index finger, middle finger, and half of the ring finger. It branches off from the median nerve as it passes through the carpal tunnel, a narrow passageway in the wrist composed of carpal bones and connective tissue.
This nerve is crucial for coordinating movements and transmitting sensory information from the hand to the central nervous system. It plays a vital role in the fine motor skills of the hand, enabling activities such as grasping objects, writing, and manipulating tools. Damage or compression of the nervus digitalis volaris communis can result in weakness, numbness, or tingling sensations in the affected digits, a condition known as median nerve entrapment or carpal tunnel syndrome.
In summary, the nervus digitalis volaris communis is a significant branch of the median nerve that provides motor innervation and sensory input to several fingers and plays a fundamental role in hand function.
