Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following relating to the thyroid is false?
A
It is located anterior to the trachea
B
It is inferior to the larynx
C
It has four lobes
D
The medial region is called the isthmus
Explanation: 

Detailed explanation-1: -The thyroid gland may have a pyramidal lobe that extends superiorly from the isthmus. The pyramidal lobe is a normal vestigial remnant of the thyroglossal duct. This has been documented to occur in 28% to 55% of individuals. Most commonly, the pyramidal lobe will originate on the left side of the thyroid.

Detailed explanation-2: -There are two main parts of your thyroid: the two halves (lobes) and the middle of the thyroid that connects the two lobes (thyroid isthmus). Your thyroid is made of thyroid follicle cells (thyrocytes), which create and store thyroid hormone (mainly T3 and T4), and C-cells, which secrete the hormone calcitonin.
