Bones Of The Upper Limb-quiz For The Homework Video

The humerus is the correct answer because it is indeed the bone of the arm and also the longest bone of the upper limb. The radius and ulna are bones of the forearm, while the scapula is a bone of the shoulder.

We have 8 carpal bones in our wrists. These bones are located between the forearm bones (radius and ulna) and the metacarpal bones of the hand. They form the wrist joint and allow for a wide range of movements in the hand and wrist.

The two bones of the shoulder girdle are the scapula and clavicle. The scapula, also known as the shoulder blade, is a flat bone located on the back of the shoulder. It provides attachment points for muscles and ligaments that help stabilize and move the shoulder joint. The clavicle, also called the collarbone, is a long bone that connects the sternum (breastbone) to the scapula. It acts as a strut, helping to support the shoulder and allowing for a wide range of motion.

The ulna is the bone located medially in the forearm. It is one of the two long bones in the forearm, with the other being the radius. The ulna is situated on the inner side of the forearm when the palm is facing upwards. It runs parallel to the radius and is slightly longer than it. The ulna plays a crucial role in forming the elbow joint and provides stability to the forearm. It also acts as an attachment site for various muscles and ligaments involved in forearm movement.

The bone of the finger is called the phalanx. The phalanx is a long, slender bone that forms the framework of the fingers. It is connected to the metacarpal bone, which is located in the palm of the hand, and the carpus, which is the group of small bones that make up the wrist. The phalanx bone allows for movement and flexibility in the fingers, enabling us to perform various tasks with our hands.

The surgical neck, also known as the collum chirurgicum, is a specific anatomical feature found on the humerus bone. It is a narrow region located just below the greater and lesser tubercles of the humerus. This area is prone to fractures and is a common site for surgical interventions, hence the name "surgical neck." It is important to identify this anatomical landmark for proper diagnosis and treatment of injuries involving the humerus bone.
