Question 8

Which statement differentiates between the intrinsic and extrinsic muscles of the larynx and explains which one moves the larynx?

Accepted Answer

A) Intrinsic muscles have both their origin and insertion on the larynx, whereas extrinsic muscles insert on the larynx but have their origin on some other structure; neither muscle moves nor displaces the larynx as a whole. 
B) Intrinsic muscles have both their origin and insertion on the larynx, whereas extrinsic muscles insert on the larynx but have their origin on some other structure; contraction of the extrinsic muscles actually moves or displaces the larynx as a whole. 
C) Intrinsic muscles have both their origin and insertion on the larynx, whereas extrinsic muscles insert on the larynx but have their origin on some other structure; contraction of the intrinsic muscles actually moves or displaces the larynx as a whole. 
D) Intrinsic muscles have both their origin and insertion outside of the larynx, whereas extrinsic muscles insert on the larynx but have their origin and insertions on the larynx and actually move or displace the larynx as a whole. 
A) Intrinsic muscles have both their origin and insertion on the larynx, whereas extrinsic muscles insert on the larynx but have their origin on some other structure; neither muscle moves nor displaces the larynx as a whole. 
B) Intrinsic muscles have both their origin and insertion on the larynx, whereas extrinsic muscles insert on the larynx but have their origin on some other structure; contraction of the extrinsic muscles actually moves or displaces the larynx as a whole.

Question 16

Question 17

There are 21 levels of branching in the bronchial tree.

Accepted Answer

A) True 
 B)False

Question 18

Anatomically, how does the right bronchus differ from the left bronchus, and what effect might this have on the aspiration of objects?

Accepted Answer

A) The right bronchus is the same size and shape as the left. Therefore, aspiration of foreign objects can occur equally often in either bronchus. 
B) The left bronchus is slightly larger and more vertical than the right. This anatomical fact helps explain why aspirated foreign objects frequently lodge in the left bronchus. 
C) The right bronchus is slightly larger and more vertical than the left. This anatomical fact helps explain why aspirated foreign objects frequently lodge in the right bronchus. 
D) The right bronchus is slightly smaller and more vertical than the left. This anatomical fact helps explain why aspirated foreign objects frequently lodge in the left bronchus.
