Question

1) For this question, which statement below is true and there is more than one once answer.

A) The capitulum is found on the lateral aspect of the humerus bone

B) the head of the radius bone is proximal process

C) the radial notch is found on the lateral aspect of the ulna bone

D) the trochlear notch is found on the ventral (anterior) aspect of the Ulna bone.  

2) Branches of the trigeminal nerve pass through all of the following foramina EXCEPT

A) mental foramen

B) foramen rotundum

C) foramen ovale

D) optic canal

E) superior orbital fissure

Answer 1

1. (A) The lateral portion of the distal articular surface of the humerus consists of a smooth, rounded eminence, named the capitulum.

(C) The radial notch of the ulna is a narrow, oblong, articular depression on the lateral side of the ulna bone.

(D) The trochlear notch is the deep anterior facing notch in the thick proximal end of the ulna.

So, the above three statements are true.

2. Mental nerve which pass through mental foramen, is itself a branch of the mandibular division of the trigeminal nerve (CN V).

The trigeminal nerve leave the skull through 3 separate foramina: the superior orbital fissure, the foramen rotundum, and the foramen ovale, respectively.

So, the branches of the trigeminal nerve pass through all of the following foramina except D) optic canal. Because it transmits the optic nerve and ophthalmic artery.
