Question

what is the distinct structure difference between pig and human rectus abdominis muscles? (fetal pig dissection lab)

Answer 1

Humans and Pigs both are mammals. So, all the major structures found in humans are present in the pig (fetal pig). The structures present may or may not have some differences with each other. For example, the human liver has four lobes whereas the pig liver has five lobes.

Similarly, rectus abdominis is a muscle which is also known as the abdominal muscle is a paired muscle which runs vertically in the human abdomen on the anterior surface of the abdomen whereas the rectus abdominis of the pig is a long-ribbon like muscle which runs in the ventral surface of the abdomen.
