The term "musculus ulnaris internua" refers to a Latin phrase that describes a specific muscle in the human body. It pertains to the muscle located on the inner side of the forearm, known as the ulnar or medial part.
The musculus ulnaris internua, also commonly referred to as the internal ulnar muscle or the inner elbow muscle, is one of the muscles that make up the forearm. It runs along the inner side of the ulna bone, which is one of the long bones in the forearm, extending from the elbow down towards the wrist.
This muscle plays a crucial role in wrist and forearm movements, particularly those related to rotating the forearm inward or medially. It also contributes to flexion of the wrist and adduction of the hand, by bringing the pinky finger closer to the midline of the body.
The musculus ulnaris internua is innervated by the ulnar nerve, which originates from the brachial plexus in the neck. This nerve supplies sensory and motor information to the muscle, allowing for voluntary control and proprioception.
Injuries or disorders affecting the musculus ulnaris internua can result in pain, weakness, or limited range of motion in the forearm and wrist. Understanding the anatomy and function of this muscle is important for anatomists, medical professionals, and individuals seeking to enhance their knowledge of the human body.
