ANS.E. The superior rectus muscle can elevate and adduct the eye from the
neutral position. From the abducted position, it is the only muscle that can elevate the eye.
The inferior oblique muscle (choice A) can elevate and abduct the eye from the neutral position.
From the adducted position, it is the only muscle that can elevate the eye.
The inferior rectus muscle (choice B) can depress and adduct the eye from the neutral position. From
the abducted position, it is the only muscle that can depress the eye.
The lateral rectus muscle (choice C) can abduct the eye.
The superior oblique muscle (choice D) can depress and abduct the eye from the neutral position.
From the adducted position, it is the only muscle that can depress the eye.

83.Which of the following will cause reduction of the size of the pulp chamber in mid-life?

A. Formation of primary dentin
B. Formation of secondary dentin
C. Internal resorption
D. External resorption
E. Pulp fibrosis

The correct answer is B. Primary dentin (choice A) surrounds the pulp chamber when the tooth is
first formed and erupts. It is the initial dentin that makes up the base of both the crown and root. If the
young tooth has a given size pulp chamber, further dentin formation, secondary dentin, later in life, will
begin to fill the chamber with dentin, making it smaller. Internal resorption (choice C) is loss of dentin,
resulting in a larger pulp chamber. External resorption (choice D) involves the exterior of the root and
does not change the pulp chamber size. Pulp fibrosis (choice E) would change the histology of the cells in the chamber, but not the chamber's size
