hand, grasping organ at the end of the forelimb of certain vertebrates that exhibits great mobility and flexibility in the digits and in the whole organ. It is made up of the wrist joint, the carpal bones, the metacarpal bones, and the phalanges. The digits include a medial thumb (when viewed with the palm down), containing two phalanges, and four fingers, each containing three phalanges.
Your hand and wrist are a complicated network of bones, muscles, nerves, tendons, ligaments and blood vessels.
The hand also serves as a highly specialized tactile organ, integrating sensory feedback that guides function in real time. The hand anatomy is a complex assembly of bones, joints, muscles, tendons, vessels, nerves, fascia, and skin, each contributing to its remarkable versatility.
Anatomy of the Hand The hand is composed of many different bones, muscles, and ligaments that allow for a large amount of movement and dexterity. There are three major types of bones in the hand itself: Phalanges. These 14 bones are found in the fingers of each hand and also in the toes of each foot. Each finger has three phalanges (the distal, middle, and proximal). The thumb only has two ...
Drawing hands can feel daunting, but the key is to break down their complexity into simple, repeatable rules. Whether you're sketching from a model or straight from your imagination, understanding ...
Hand surgeons use Verdan’s zones to classify tendon injuries. This system divides the hand and forearm into five zones (plus additional zones for the thumb). Each zone has its own challenges when it comes to tendon repair. Zone I: This is the fingertip region, from the tip of the finger to the middle of the middle phalanx.
