Muscle Opponens Thumb (M. Opponens Pollicis, Pna, Bna, Jna)

The muscle opposing the thumb (m. Opponens pollicis) is a muscle of the hand that opposes the thumb to the other fingers. It is located on the palm and starts from the base of the thumb. This muscle is involved in flexing the thumb and opposing it to the other fingers, as well as in adducting the thumb towards the index finger.

The opponus pollicis muscle has three heads: anterior, posterior and lateral. The anterior head begins from the lateral surface of the middle phalanx of the thumb, the posterior - from the medial surface of the proximal phalanx of the index finger, and the lateral - from the lateral edge of the distal phalanx of the middle finger.

This muscle is one of the most important muscles of the hand as it is involved in many movements such as opening and closing doors, using tools and performing other activities. Therefore, it is important to monitor its condition and regularly perform exercises to maintain its functionality.

The opponsus thumb muscle is a small muscle tissue located deep in the palm. It is responsible for bending the thumb and its opposition to the other fingers. This muscle is involved in a variety of movements, such as grasping objects, holding tools, and writing on a keyboard. However,
