Wrist Anatomy Flashcard

Front

What is the MCP joint?

Back

The Metacarpophalangeal (MCP) joint is the joint between the metacarpal bones of the hand and the proximal phalanges of the fingers. It allows for flexion, extension, abduction, and adduction of the fingers.

Front

What is the radius?

Back

The radius is one of the two long bones in the forearm, located on the thumb side. It is involved in the movement of the wrist and forearm.

Front

What is the DIP joint?

Back

The Distal Interphalangeal (DIP) joint is the joint between the distal and middle phalanges of the fingers. It allows for flexion and extension of the fingertip.

Front

What is the trapezium bone?

Back

The trapezium is one of the carpal bones located at the base of the thumb. It plays a crucial role in thumb movement and opposition.

Front

What are phalanges?

Back

Phalanges are the bones in the fingers and toes. Each finger has three phalanges (proximal, middle, and distal), while the thumb has two.

Front

What are metacarpals?

Back

Metacarpals are the five long bones in the hand that connect the wrist to the fingers. They form the framework of the palm.

Front

What is the function of the wrist joint?

Back

The wrist joint allows for a wide range of motion, including flexion, extension, radial and ulnar deviation, and circumduction, enabling various hand movements.

Front

What is the ulna?

Back

The ulna is the second of the two long bones in the forearm, located on the side opposite the thumb. It is involved in forming the elbow joint.

Front

What is the significance of the scaphoid bone?

Back

The scaphoid is one of the carpal bones and is important for wrist stability and movement. It is the most commonly fractured carpal bone.

Front

What is the role of ligaments in the wrist?

Back

Ligaments are strong connective tissues that connect bones to other bones. In the wrist, they provide stability and support during movement.
