The word "musculus" means muscle, and "supinator" refers to a muscle that rotates the forearm outward. The phonetic transcription of this word in the International Phonetic Alphabet (IPA) is /mʌskjʊləs supɪneɪtər/, which accurately represents the pronunciation.

MUSCULUS SUPINATOR Meaning and Definition

1. Musculus supinator, also known as the supinator muscle, is a key muscle located in the upper limb that plays a crucial role in the movement of the forearm. More specifically, the musculus supinator is responsible for the supination of the forearm, which is the movement of turning the palm of the hand from a pronated or downward-facing position to a supinated or upward-facing position.

   The musculus supinator originates from two main sources: the lateral epicondyle of the humerus (upper arm bone) and the radial collateral ligament. From there, it travels downward and laterally, forming a cylindrical shape around the radius bone of the forearm. This cylindrical shape is known as the supinator canal. Once reaching the forearm, the muscle inserts onto the lateral side of the proximal radius.

   The primary function of the musculus supinator is to engage in the supination of the forearm. This movement is critical for performing various activities, such as turning a doorknob, holding a spoon, or throwing a ball with a palm-upward position. The musculus supinator contracts to rotate the radius bone, allowing the palm to face upward and creating a more efficient position for gripping and carrying objects.

   Injuries or conditions that affect the musculus supinator can result in pain, weakness, or limited range of motion in forearm supination. Rehabilitation exercises and treatments targeting this muscle may be prescribed to improve its strength and function, thereby restoring optimal movement in the forearm and hand.

2. M. supinator radii brevis; origin, external epicondyle of humerus and supinator ridge of ulna; insertion, anterior and outer surface of radius; nerve supply, radial (dorsal interosseous); action, supinates the forearm.

Etymology of MUSCULUS SUPINATOR

The term musculus supinator is derived from two Latin words: musculus and supinator.

1. Musculus: In Latin, musculus means muscle. It is the diminutive form of mus, which translates to mouse. The comparison to a mouse is due to the small, wiry appearance of some muscles.

2. Supinator: Similarly, supinator is derived from the Latin verb supinare, which means to turn upward or backward. In this context, it refers to the action performed by the supinator muscle, which externally rotates the forearm and turns the palm face up.

Combining these Latin terms, musculus supinator literally means the muscle that turns the palm face up.
