Question

Acromion is part of
A. Vertebral column
B. Pelvic girdle
C. Femur
D. Pectoral girdle/Scapula

Answer 1

Hint: The basic structure of the human body is composed of the skeleton. The skeleton is composed of fused and individual bones held together by muscles, ligaments, tendons. The skeleton has many parts and divisions, each of which have a specific function to serve.

Complete answer:
Skeleton is the part of our body that serves to protect the internal soft tissues. In vertebrates, the skeleton comprises bones which are mineralized tissues. There are many bones in the body of a vertebrate that are held together by muscles, ligaments and tendons. The location of articulation of two bones is called a joint.
In the human skeleton, the pectoral girdle comprises the bones that help to articulate arms to the main skeleton of the body. It is composed of scapula, clavicle and coracoid. The acromion is a bony projection on the Scapula. It serves as a point of attachment of muscles and is very important to the proper functioning of the shoulder. The acromion forms the acromioclavicular joint in association with the clavicle. Acromion, along with the pectoral girdle helps to rotate and move the hands and shoulder.
The vertebral column is a bony structure characteristic of all vertebrates. It is composed of the vertebrae which form a canal that houses the spinal cord. The vertebral column encloses the spinal cord. The acromion is not present in the vertebral column.
Pelvic region of our body is the region between the lower abdomen and the thighs. Pelvic girdle is the set of bones that connect the pelvic region of the body with the lower limbs or legs. The bones are – ilium, ischium and pubis. They form a ring-like structure. The space enclosed by the pelvic bones form the pelvic cavity that contains our reproductive organs and the rectum. Acromion, is therefore, not a part of the pelvic girdle.
Femur is also known as the thigh bone. It is well developed in tetrapods and is the largest bone in the human body. The head of the femur is articulated with the pelvic bones to form the hip joint. Acromion is not a part of the femur.
Therefore, from the above discussion it can be concluded that option (d) is correct.

Note: Skeletons form the basic structure of our body. It is composed of bones and provides protection to the internal tissues and organs. Pectoral girdle or the shoulder girdle is formed by clavicle, scapula and coracoid. Acromion is a bony projection on the scapula and it functions as a point of muscle attachment.
