Which one of the following is the correct matching of three items and their grouping category?
Correct answer: A. Ilium, ischium and pubis -> Coxal bones of pelvic girdle
- A. Ilium, ischium and pubis -> Coxal bones of pelvic girdle
- B. Actin, myosin, rhodopsin -> Muscle proteins
- C. Cytosine, uracil, thiamine -> Pyrimidines
- D. Malleus, incus, cochlea -> Ear ossicles
Explanation
The correct matching of the three items and their grouping category is: Ilium, ischium, and pubis -> Coxal bones of the pelvic girdle The ilium, ischium, and pubis are three separate bones that fuse together to form the coxal bone, which is commonly referred to as the hip bone. Together, these three bones make up the pelvic girdle, which provides support and stability to the lower part of the body and connects the spine to the lower limbs. The pelvic girdle is formed by two innominate bones (hip bones). Each innominate bone consists of three separate bones, ilium, ischium, and the pubis.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
