Which tissues below are typically derived from the single-celled epithelium on the dorsal surface of a chick embryo after gastrulation?
A)muscle
B)skin, ectodermal tissues and the nervous system
C)only skin
D)only ectodermal tissues
E)only tissues of the nervous system

Question

Quizplus · Accepted Answer

The ectoderm on the dorsal surface of a chick embryo after gastrulation gives rise to skin, ectodermal tissues (such as hair, feathers, etc.), and the nervous system. Therefore, the correct answer is B. Muscle is derived from mesoderm, which is formed during gastrulation and is not derived from the ectoderm. Similarly, choices C, D, and E are too narrow and do not encompass all the tissue types that are derived from the dorsal surface ectoderm.
