Upper Limbs Anatomy Quiz

The humerus is the single bone of the arm. It is the long bone that extends from the shoulder to the elbow and is responsible for connecting the shoulder girdle to the forearm. The ulna is one of the two bones in the forearm, while pivot and hinge are not bones but rather types of joints. Therefore, the correct answer is humerus.

The humerus, the long bone in the upper arm, has two distal ends. The distal end of a bone refers to the end farthest from the body's center. In the case of the humerus, the distal end is located at the elbow joint. This end features two prominent bony landmarks: the trochlea, which articulates with the ulna, and the capitulum, which articulates with the radius. These two distinct articulating surfaces contribute to the complex movement capabilities of the elbow joint.

The correct answer is the lateral part. The question is asking about the location of the radius, which is one of the two bones in the forearm. The radius is located on the lateral side of the forearm, which means it is positioned towards the thumb side of the arm when the palm is facing up.

The ulna is the medial bone of the forearm. It is located on the inner side of the forearm and runs parallel to the radius. The ulna is longer and larger than the radius and plays a key role in the stability and movement of the forearm and wrist. It articulates with the humerus at the elbow joint and forms a joint with the radius at both ends, allowing for rotation and movement of the forearm.

The correct answer is 8 because the hands have 8 carpal bones. These carpal bones are located in the wrist and are arranged in two rows. They are responsible for providing stability and flexibility to the wrist joint, allowing for a wide range of movements.

Each limb has 5 metacarpals. The metacarpals are the bones in the hand that connect the wrist bones to the fingers. There are 5 metacarpals in each hand, one for each finger. Therefore, the correct answer is 5.

The term "limb" commonly refers to the legs of the body. The legs are the parts of the body that are used for walking, running, and other forms of locomotion. They are typically attached to the torso and provide support and movement for the body. The head and torso are not usually referred to as limbs, although they are important parts of the body. Therefore, the correct answer is legs.

The upper limb consists of three parts: the arm, the forearm, and the hand. Each part has its own distinct set of bones, muscles, and joints that work together to allow for movement and function. Therefore, the correct answer is three.

The term "capitulum" refers to a small head. It is a Latin word that is commonly used in anatomy to describe a rounded or knob-like structure resembling a head. In this context, capitulum is being used to describe a small head. Therefore, the correct answer is "Small head".

The correct answer is 30. The upper limb consists of the arm, forearm, and hand. It includes the humerus, radius, ulna, carpals, metacarpals, and phalanges. In total, there are 30 bones in the upper limb.
