The spelling of the term "nervus cutaneus antibrachii lateralis" may seem intimidating at first glance, but it follows the principles of Latin root words and anatomical terminology. Using IPA phonetic transcription, the pronunciation would be [ˈnɛrvəs kjuːˈteɪniəs ˌæntiˈbrækii lətəˈreɪlɪs]. "Nervus" refers to a nerve, while "cutaneus" means relating to the skin. "Antibrachii" indicates the forearm, and "lateralis" denotes the side. In short, this term describes a nerve that provides sensation to the lateral side of the forearm.
The term "nervus cutaneus antibrachii lateralis" refers to a specific nerve found in the human body. The word "nervus" is Latin for nerve, while "cutaneus" means relating to the skin, and "antibrachii" refers to the forearm. "Lateralis" indicates that the nerve is situated on the outer side of the forearm.
The nervus cutaneus antibrachii lateralis is a sensory nerve that provides innervation to the lateral side of the forearm. It originates from the brachial plexus, a complex network of nerves located in the shoulder region. From there, it courses down the arm, specifically running along the outer side of the forearm.
The main function of the nervus cutaneus antibrachii lateralis is to transmit sensory information from the skin on the lateral aspect of the forearm to the central nervous system. It carries signals related to touch, pressure, temperature, and pain sensations originating from this region. These sensory inputs then allow the brain to perceive and interpret stimuli, which may aid in motor responses or awareness of the external environment.
Injuries or compression of the nervus cutaneus antibrachii lateralis may lead to abnormal sensations or even numbness, tingling, or pain in the affected area. Understanding the anatomy and functions of this nerve is essential in diagnosing and treating any related conditions or disorders.
Lateral antibrachial cutaneous nerve, terminal cutaneous branch of the musculocutaneous nerve; it is purely sensory, supplying the radial side of the forearm.
