& Embryology Questions
SECTION A: EMBRYOLOGY AND DEVELOPMENTAL ANATOMY
1. The endoderm germ layer gives rise to which of the following structures?
A) Skeletal muscle and bone
B) Central nervous system and peripheral nerves
C) Gastrointestinal tract and respiratory tract epithelium
D) Cardiovascular system and blood cells
E) Dermis and adrenal cortex
Answer: C
Explanation: The endoderm is the innermost germ layer and forms the epithelial lining of the
gastrointestinal tract, respiratory tract, and associated organs including the liver and pancreas.
The other options are derived from mesoderm (A, D) and ectoderm (B), with E describing
mesodermal derivatives.
2. The paraxial mesoderm is anatomically divided into which two components?
A) Somatic and splanchnic layers
B) Epimere and hypomere
C) Dorsal and ventral regions
D) Medial and lateral plates
E) Superficial and deep layers
Answer: A
Explanation: The paraxial mesoderm differentiates into somatic (parietal) and splanchnic
(visceral) layers. The somatic layer gives rise to skeletal muscle of the body wall and limbs,
while the splanchnic layer forms smooth muscle of the gut and associated organs.
,3. Which of the following structures is derived from the somatic layer of paraxial
mesoderm?
A) Visceral smooth muscle
B) Cardiac muscle
C) Skeletal muscle of the body wall
D) Vascular endothelium
E) Glandular epithelium
Answer: C
Explanation: The somatic (parietal) layer of paraxial mesoderm develops into skeletal muscle of
the body wall and limbs. The splanchnic layer (A) forms smooth muscle of the viscera. Cardiac
muscle (B) is derived from lateral plate mesoderm, and endothelium (D) and glandular
epithelium (E) have different embryological origins.
4. The intermediate mesoderm is primarily responsible for the formation of:
A) The adrenal medulla and sympathetic chain
B) The urogenital system and kidneys
C) The vertebral column and ribs
D) The appendicular skeleton
E) The dermis of the back
Answer: B
Explanation: The intermediate mesoderm gives rise to the urogenital system, including the
kidneys, gonads, and their associated ducts. The adrenal medulla (A) is derived from neural crest
cells, while the vertebral column (C) and appendicular skeleton (D) arise from paraxial and
lateral plate mesoderm respectively.
5. Lateral plate mesoderm contributes to the development of:
A) Neural crest cells and peripheral ganglia
B) Adrenal cortex, blood cells, and lymphatic cells
, C) Skeletal muscle of the limbs
D) The notochord and nucleus pulposus
E) The lens of the eye
Answer: B
Explanation: The lateral plate mesoderm differentiates to form the adrenal cortex, blood cells,
and lymphatic cells. It also gives rise to the cardiovascular system, serous membranes, and some
connective tissues. Neural crest (A) is ectodermal, limb skeletal muscle (C) is from paraxial
mesoderm, and the lens (E) is derived from surface ectoderm.
6. The ectoderm is subdivided into which two primary components?
A) Somatic and splanchnic layers
B) Surface ectoderm and neuroectoderm
C) Epiblast and hypoblast
D) Neural tube and neural crest
E) Epidermis and dermis
Answer: B
Explanation: The ectoderm divides into surface ectoderm, which forms the epidermis and its
derivatives, and neuroectoderm, which gives rise to the neural tube and neural crest. D describes
derivatives of neuroectoderm rather than subdivisions. E confuses germ layer with tissue layers.
7. The neuroectoderm gives rise to:
A) The epidermis and hair follicles
B) The neural tube and neural crest
C) The lens and cornea of the eye
D) The enamel of teeth
E) The pituitary gland
Answer: B
