-
Atrium
-
Closing apparatus
-
Peritreme
-
Peristigmatic glands

Arytenoid cartilages
-
Cuneiform cartilages
-
Corniculate cartilages
-
Thyroid cartilage
-
Cricoid cartilage
D
Correct answer
Explanation
This forms the Adam's apple. It is usually larger in males than in females. The thyrohyoid membrane is a ligament associated with the thyroid cartilage that connects the thyroid cartilage with the hyoid bone.
-
There are almost fifteen to twenty incomplete C-shaped tracheal rings of cartilage.
-
The trachea is lined with pseudostratified columnar epithelium.
-
The cricoid cartilage is the only complete ring of cartilage in the trachea.
-
A flap-like epiglottis closes the opening to the larynx during swallowing.
-
The esophagus lies anteriorly to the trachea.
E
Correct answer
Explanation
The esophagus lies posteriorly to the trachea. Circular bands of fibrous connective tissue called the annular ligaments of trachea join the tracheal rings together.

Renal pyramids
-
Renal sinuses
-
Calyces
-
Renal columns
A
Correct answer
Explanation
The renal pyramids are conical segments within the internal medulla of the kidney. The pyramids contain the secreting apparatus and tubules, and are also known as the malphighian pyramids.
-
renal sinus
-
hilus
-
cortex
-
calyx
B

-
ciliated columnar epithelial
-
olfactory epithelium
-
cuboidal stratified tissue
C
Correct answer
