Abstract:
Rupture of the tendon of flexor pollicis longus is suspected when active flexion of the interphalangeal joint of the thumb is not possible. This can be a result of trauma but, when spontaneous, diagnostic confusion can exist as incomplete palsy of the anterior interosseous nerve can present in a similar way. We describe a simple clinical sign which can differentiate between these conditions.

Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

Reflex Activity
A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
