Answer 1

1. In fetal pig, the muscle which works opposite to the gluteus medius muscle is the "Gluteus maximus" muscle because both of these muscles runs perpendicular to each other i.e., gluteus medius runs perpendicular to gluteus maximus, and gluteus maximus runs perpendicular to gluteus medius. So, both of these muscles works opposite to each other.

2. Although the gluteus maximus in the fetal pig is smaller than the gluteus minimus, gluteus maximus is still considered as 'maximus' because it extends from the last sacral to the first caudal vertebrae. Also it can be lifted up but the gluteus minimus cannot be lifted up. So, considering all these aspects, gluteus maximus is still called as 'maximus' even though it is smaller than gluteus minimus.

3. In the fetal pig, other than ischium, the pelvic girdle is formed by other components of the ilium and the pubis. The ilium is the largest and the most recognizable part of pelvis and it forms the posterior part of pelvic girdle by articulating with the sacrum. The pubis forms the anterior part of pelvic girdle by articulating with pubic symphysis. The ischium forms the bottom part of pelvic girdle.

4. The three hormones produced by the thyroid gland are: Triiodothyronine (T3), Tetraiodothyronine or Thyroxine (T4) and Calcitonin. Triiodothyronine and Thyroxine are the the essential hormones for the growth and development of fetus. T3 hormone plays a vital role in body's metabolic and heart rates. T4 hormone plays a vital role in digestion and brain development.

5. T-cells are important in the immune system in our body. These cells play major role in defense against intracellular pathogens like bacteria and viruses. T-cells also helps in providing immunity to extracellular pathogens.
