Question

Acromion process is a part of
A. Vertebral column
B. Pelvic girdle
C. Femur
D. Pectoral girdle

Answer 1

Hint: The acromion process is a bony process which is an important part of the skeletal system of the body.

Complete Answer:
- In osteology (study of bones), a process is a projection which extends off of a bony tissue. Bones of the many vertebrates have these processes. These projections of body tissues serve as attachment for muscles.
- Processes help our body to move or to take actions in order to perform many tasks like walking, fighting, running, swimming, etc.

Acromion process:
- Acromion process articulates with the clavicle or collarbone to form acromioclavicular joints.
- Articulated bones are connected with the help of cartilage or ligaments.
- The articulation between the bones allows them for movement. Acromion process is a part of Scapula (shoulder bone) or pectoral girdle.
- Acromion process extends anteriorly from the spine of the scapula. Acromion is a large, triangular or oblong process.

Additional information:
Vertebral column: Vertebral column is also called as the spinal column. The vertebral column provides attachment to the muscles and support to the body. The Vertical column protects the spinal cord. It is also the site of haemopoiesis (blood cells formation).

Pelvic girdle: Pelvic girdle is composed of the hip bones (illium, ischium, pubis).

Femur: Femur is the thigh bone. It is the largest bone present in the human body.

Pectoral girdle: Pectoral girdle is also called the Shoulder girdle. It is a set of bones which connects to the arms on each side. Pectoral girdles consist of clavicle and scapula and coracoids.

Hence, option D is the correct option for this question.

Note: All these bones together form a skeletal system. Skeletal system is the internal framework of the body of an organism. Number of bones present in the skeletal system vary in different species such as in the human skeletal system composed of 206 bones.
