-|| The term "ectomesenchyme" refers to {{neural crest}} ('''ecto'''derm) forming connective tissue structures ('''mesenchyme''') in the head.
+|| Both neurons and glia differentiate from ventricular neural stem cells. Neurons first and later goal development.

+- &nbsp; the differentiating neural cells migrate away from ventricular layer
+|| Incorrect!

+- &nbsp; the pancreas
-+ ectoderm and endoderm
+|| Incorrect! The {{pancreas}} develops from {{endoderm}} and {{mesoderm}} within the embryo.
-- none of the above is correct
+- &nbsp; the spleen
-|| The buccopharyngeal membrane ({{oral membrane}}) consists of {{ectoderm}} and {{endoderm}} together. Endoderm layer of the foregut
+|| Incorrect! The {{spleen}} develops within the dorsal mesentery ({{mesoderm}}) of the gastrointestinal tract within the embryo.
- 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}}.
++ &nbsp; the ileum
+|| Correct! The ileum ({{small intestine}}) develops and grows in length during the embryonic and early fetal period lying within the extra-embryonic coelom outside the body cavity.
+- &nbsp; none of the above
+|| Incorrect! The ileum ({{small intestine}}) develops and grows in length during the embryonic and early fetal period lying within the extra-embryonic coelom outside the body cavity.
