Textbook Question
Chapter 3, Problem 21RQ
In anatomy lab, Thaya pointed to the vertebrae of a cadaver and said "sclerotome."
He pointed to a kidney and said, “intermediate mesoderm, “to the biceps muscle in
the arm and said, "splanchnic mesoderm, “to the inner lining of the stomach and
said, " endoderm, " and to the brain and said, "ectoderm." Point out Thaya's one
mistake.

The major body part(s) derived from ectoderm is/are
The peritoneum (as well as the pleurae and pericardium) of an adult body
arose from the
layer of a developing embryo.
O at this point in the semester, I really don't care! (don't pick this one, even if it's

mesoderm
You are dissecting a young fetal pig whose testes have
not descended yet. To find the testes in this pig you
should look:
● Ventral to the abdominal cavity
Inside the scrotum
O Caudal to the kidneys
O Cranial to the kidneys
