Here are a few simple questions that relate to mesoderm development. Take the quiz and see what you know, if you get some wrong, try working through through the Embryology Lecture on Mesoderm.

Take the Quiz

1 Mesenchyme refers to the middle layer of the trilaminar embryo

	true
	false

2 The intraembryonic coelom forms within :

	somites
	lateral plate
	neural tube
	intermediate mesoderm

3 Somites are developmental structures that contribute the following adult structures :

	vertebra, notochord, dermis, skeletal muscle
	vertebra, intervertebral discs, dermis, skeletal muscle
	kidney, body wall connective tissue, sensory ganglia
	kidney, gastrointestinal tract smooth muscle, mesentry

4 All paraxial mesoderm segments into somites.

	true
	false

5 Which of the following statements about somites is/are correct:

	Differentiate a covering epithelium in their early stages.
	Somites contribute the body wall osteogenic, chrondrogenic and fibrogenic cells.
	Contribute to a single vertebral level body and the intervertebral disc.
	Myotomes contribute the smooth muscle associated with the gastrointestinal tract wall.
