 Here are a few simple Quiz questions that relate to Week 3 ({{GA}} week 5) from the lecture and practical.

 <quiz display=shuffle>
-{Which of the following best describes the term "ectomesenchyme":
+{During embryonic disc folding in week 3 only the ectoderm layer folds ventrally left, right and above and below the notochord.
 |type="()"}
-- ectoderm derived from mesoderm
+- &nbsp; true
-- epithelium derived from connective tissue
++ &nbsp; false
-- sensory placodal induction by mesoderm
+|| During folding in the third week all three germ cell layers (ectoderm, mesoderm and endoderm) fold together ventrally as described.
-+ connective tissue derived from neural crest
-- none of the above is correct
-|| The term "ectomesenchyme" refers to {{neural crest}} ('''ecto'''derm) forming connective tissue structures ('''mesenchyme''') in the head.
-{Which of the following best describes the buccopharyngeal membrane structure:
+{The intraembryonic coelom finally forms
 |type="()"}
-- a ventral surface indentation in the early embryo head
++ &nbsp; pericardial, pleural and peritoneal cavity.
-- endoderm layer of the foregut
+- &nbsp; single pericardial cavity and two pleural and two peritoneal cavities.
-- ectoderm layer of the epidermis
+- &nbsp; neural tube lumen, gastrointestinal tract lumen and neural crest.
-+ ectoderm and endoderm
+- &nbsp; the paired dorsal aortas running the embryo.
-- none of the above is correct
-|| The buccopharyngeal membrane ({{oral membrane}}) consists of {{ectoderm}} and {{endoderm}} together. Endoderm layer of the foregut
+|| The intraembryonic coelom finally forms the 3 P's. There is only one peritoneal cavity. These other anatomical spaces have noting to do with intraembryonic coelom. The dorsal aortas form within the splanchnic mesoderm.
- and ectoderm layer of the epidermis are partially correct. The ventral surface indentation in the early embryo head is the stomedeum, on the floor of which is located the {{buccopharyngeal membrane}}.
