Solution
A long flat bone found in the middle portion of the chest is the sternum, or breastbone. A process acromion is present in a pectoral girdle through which a glenoid cavity articulates.
Complete answer:
First we should know about locomotion and movements of living organisms to answer this question. Motion is when the living thing moves a part of the body without changing the location of the organisms. Locomotion is where the movement of the body part contributes to a change in the organism's position and location. All of things are brought in by the skeletal and muscular systems' combined efforts. In all vertebrates and invertebrates, movements can be seen.
Now, let us find the solution from the options-
Bones whose primary role is either extensive defence or the provision of large surfaces for muscular attachment are flat bones. In the sternum, cranium (skull), the rib cage, and the ilium (pelvis) these bones are found which are compressed into wide, flat plates. Occipital, prefrontal, parietal, vomer, nasal, lacrimal, hip, ribs, sternum, and scapulae are the flat bones. From this we came to know that A matches with (iv).
Pectoral girdle is found in the shoulder. Two separate pectoral girdles are present. Clavicle and scapula are the two bones that present in each pectoral girdle. Glenoid cavity is found in each pectoral girdle into which the humerus head is articulated. From this we came to know that B matches with (iii).
Synovial fluid occurs in the knuckles and in several other body joints as a biochemical material. Its role is to provide lubrication and cushioning to the associated bones in the joint during movement. From this we came to know that C matches with (i).
Vertebrae are the cartilaginous segments that make up the spinal column, consisting of many distinct parts that never combine in certain lower vertebrates and a broad, more or less cylindrical structure in higher vertebrates whose ends are articulated by elastic or cartilaginous tissue pads with those of corresponding vertebrae and a bony arch that encircles the spinal cord. From this we came to know that D matches with (ii).
Thus, the correct answer is option (B) A- (iv), B-(iii), C- (i), D- (ii)
Note: In the body, a total of 206 bones are included. They are separated into the skeleton of the Axial and the appendicular. The axial skeleton consists of bones, including the sternum, the vertebrae, and the skull situated at the middle of the body. An integral part of the locomotive system is joints.
