Question 1

________ Tubotympanic recess
A) First pharyngeal pouch
B) Second pharyngeal pouch
C) Third pharyngeal pouch
D) Fourth pharyngeal pouch
E) Fifth pharyngeal pouch

Accepted Answer

The epithelium and the glands of the pharyngotympanic tube are derived from the elongated tubotympanic recess,the expanded first pharyngeal pouch.This recess also gives rise to the tympanic cavity and antrum.The connective tissue and cartilaginous parts of the tube are derived from the mesenchyme surrounding the tubotympanic recess.

Accepted Answer

The image shows the middle ear and its associated structures. The tubotympanic recess, also known as the epitympanic recess, is located above the tympanic membrane (letter C) and is connected to the auditory tube. Choices A, B, D, and E do not correspond to the tubotympanic recess.

Question 10

________ Inferior parathyroid gland
A) First pharyngeal pouch
B) Second pharyngeal pouch
C) Third pharyngeal pouch
D) Fourth pharyngeal pouch
E) Fifth pharyngeal pouch

Accepted Answer

The dorsal bulbar part of each third pharyngeal pouch differentiates into a parathyroid gland.These glands migrate caudally with the thymus,which develops from the ventral portions of this pair of pharyngeal pouches.Hence,the parathyroid glands derived from the third pair of pouches come to lie further caudally than those from the fourth pair of pouches.Because of this descent,sometimes the inferior parathyroid glands are located in other than their normal position;that is,they may be drawn into the thorax by the descent of the thymus.

Question 11

________ Thymus
A) First pharyngeal pouch
B) Second pharyngeal pouch
C) Third pharyngeal pouch
D) Fourth pharyngeal pouch
E) Fifth pharyngeal pouch

Accepted Answer

The elongated ventral parts of the third pair of pharyngeal pouches migrate medially and fuse to form the primordium of the thymus.Development of the thymus is not complete at birth;it continues to grow and reaches its greatest size at puberty.Thereafter it becomes very small and is difficult to locate.

Question 12

________ Internal branchial sinus
A) First pharyngeal pouch
B) Second pharyngeal pouch
C) Third pharyngeal pouch
D) Fourth pharyngeal pouch
E) Fifth pharyngeal pouch

Accepted Answer

The second pharyngeal pouch gives rise to the lining of the palatine tonsils and the internal branchial sinus.

________ Superior parathyroid gland
A) First pharyngeal pouch
B) Second pharyngeal pouch
