What are hand and wrist bones called?

The wrist is closer to the torso than the fingers. Therefore it is “proximal” when compared to your fingers. The closer something is to the point of origin, the more proximal it is.

What are arm bones called?

Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius).

• Scaphoid. The scaphoid is a bone in the wrist.
• Lunate. The lunate is a bone in the middle of the wrist in the first row of wrist bones.

Extending from the wrist to the elbow joint is the region of the upper extremity called the forearm (antebrachium). The forearm helps the shoulder and the arm in force application and the precise placement of the hand in space, with the help of the elbow and radioulnar joints.

Is the wrist distal to the arm?

Proximal and Distal They describe the position of a structure with reference to its origin – proximal means closer to its origin, distal means further away. Examples: The wrist joint is distal to the elbow joint.

Is the wrist is distal to the hand?

In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist. Distal is the opposite of proximal.

What are the bones of the hand?

• Phalanges. The 14 bones that are found in the fingers of each hand and also in the toes of each foot.
• Metacarpal bones. The 5 bones that compose the middle part of the hand.
• Carpal bones. The 8 bones that create the wrist.

How carpal bones are named?

These 8 bones are named for their unique shapes; Scaphoid (boat), Lunate(Crescent), Triquetrum(3-cornered), Pisiform(pea), Trapezuim(Table), Trapezoid(quadrilateral), Capitate(head shaped), and Hamate (hook-shaped).

What is the anatomy of the hand and wrist?

Anatomy of the Hand and Wrist: Bones, Muscles, Tendons, Nerves. The wrist links the hand to the arm. The wrist is a complex mechanical system of 8 small bones known as the carpal bones. The carpal bones are arranged in 2 interrelated rows. One row connects with the ends of the bones in the forearm— radius and ulna.

What are tendons and ligaments in the wrist?

ulnocarpal and radioulnar ligaments – two sets of ligaments that provide the main support for the wrist. Tendons are bands of connective tissue that attach the muscles to the bone enabling the muscles to move the bones. The main tendons of the hand are:

Where do the nerves of the hand and wrist originate?

The nerves of the hand and wrist originate from the structure called the brachial plexus which is located proximally in the root of the neck and axillary region. This plexus is formed from the combination of the anterior rami of the spinal nerves C5-T1 and is responsible for motor and sensory innervation of the upper limb.
