Ulna, Radius, Wrist And Hand Skeletal Anatomy

The olecranon of ulna is the bony prominence on the ulna that forms the point of the elbow. The coracoid process of the ulna, radial tuberosity of ulna, and styloid process of ulna are distinct structures and not related to the point of the elbow.

The coronoid process of the ulna is a bony projection on the top of the ulna bone in the forearm. It plays a key role in the articulation of the elbow joint.

The trochlear notch of the ulna is the semilunar notch on the upper end of the ulna that articulates with the trochlea of the humerus.

The specific part of the ulna referred to in this question is the 'head of ulna', which is located at the proximal end of the bone.

The styloid process of the ulna is a bony prominence on the distal end of the ulna, while the other options mentioned are different parts of the ulna.

The head of radius is the term used to identify the upper end of the radius bone. It articulates with the capitulum of the humerus at the elbow joint.

The radial tuberosity is a specific bony projection on the radius bone, while the incorrect answers refer to different structures on other bones of the arm.

The correct term for the pointed projection at the end of the radius bone is the styloid process of radius, which serves as an attachment point for ligaments and muscles.

The scaphoid bone is the carpal bone located on the thumb side of the wrist. It is one of the eight carpal bones in the human hand.

The lunate is one of the eight carpal bones in the human hand, located between the scaphoid and triquetrum. It is commonly referred to as the lunate due to its moon-like shape.

The correct answer is the triquetrum, which is also known as the triangular or triangular fibrocartilage complex. The scaphoid, lunate, and trapezium are other carpal bones but are not commonly referred to as the triquetrum.

The pisiform is a small carpal bone located in the wrist, commonly known for its pea-like shape. The scaphoid, lunate, and triquetrum are other carpal bones found in the wrist.

The trapezium is a carpal bone located at the base of the thumb. It is shaped like a small, four-sided pyramid.

The trapezoid bone is one of the eight carpal bones in the human hand. It is located between the scaphoid and the second metacarpal bone.

The capitate is one of the eight carpal bones in the human hand, located in the center of the wrist. It is commonly mistaken for other carpal bones such as the scaphoid, hamate, and triquetrum.

The correct carpal bone in this case is the hamate, which is located on the ulnar side of the wrist. The scaphoid, trapezium, and pisiform are also carpal bones, but they are not the one depicted in the question.

Metacarpal bones are a set of five long bones in the human hand that are located between the wrist and the fingers. They help provide structure and support for the hand.

Phalanges are the bones found in the fingers and toes, while metacarpals are in the hands, femurs are in the thighs, and the ribcage is a set of bones protecting the chest area.

The thumb is also known as the pollex, while the pinky, index finger, and ring finger are all distinct fingers on the hand with their own names.
