Question

Identify the specific bone for marking no. 1 and classify the bone based on its shape- marking No. 1

The image shows an X-ray of the right elbow joint, labeled with three key anatomical points:

1. **Point 1**: This label is pointing to the olecranon process, which is the bony prominence of the ulna at the elbow. It forms the upper part of the trochlear notch and is essential for elbow movement.

2. **Point 2**: This label points to the distal portion of the humerus. The humerus is the long bone of the upper arm, and this part forms a joint with the ulna and radius at the elbow.

3. **Point 3**: This label indicates the head of the radius, which is the disc-shaped top of the radius bone. The radius is one of the forearm bones and allows for the rotation of the forearm.

The X-ray provides a lateral view of the elbow joint, which helps in assessing bone alignment and identifying any potential fractures or dislocations.

Expert Solution
Step 1

Anatomy is the branch of biology that deals with the study of the structure of organisms and their parts. Anatomy helps us to understand the function and structures of an organ. The anatomical terms of position are necessary for recognition and applying anatomy. They help to avoid any confusion that can occur when specifying the location of structures.

A bone is a stiff organ that frames components of the vertebrate skeleton in animals. Bones protect the several vital organs of the body such as the heart, lungs, liver, ETC, produce RBC (Red blood cells), and WBC (White blood cells), reserve minerals, give structure and support for the body and facilitate movement. Bones are found in different shapes and sizes.
