  1. frontal
  2. occipital
  3. lacrimal
  4. temporal

Short Answer

Expert verified

The correct answer is option (c).

Lacrimal bone is one of the facial bone.

Step by step solution

01

Features of the facial bone

  • Mandible, maxilla, frontal bone, nasal bones, and zygoma are the main bones of the face.
  • There are 6 paired and 2 unpaired facial bones among the 14 facial bones that make up the face skeleton, which have distinct anatomical structures and go through a development of the embryo.
  • The soft tissues of the face are protected by the facial bones, which also help with structure, breathing, eating, and facial reactions.
02

Step: 1 Explanation for Correct answer

  • The lacrimal bone is a face bone.
  • A pair of facial bones called the lacrimal bones are situated in the orbit's medial wall.
  • Above the lateral edge of the eye, the lacrimal gland is found in the orbit.
  • The tear-producing mechanism of the eye is supported by lacrimal bones. Thus, the option c is correct.
03

Step: 2 Explanation for incorrect answer

  • An adult's unpaired frontal bone is a component of the bony framework that makes up the superior and anterior sections of the skull. So, option a is wrong.
  • The most posterior cranial bone and primary bone of the occiput is the occipital bone. It is viewed as a flat bone. So, option b is wrong as well.
  • The unusual shape of the temporal bone typically qualifies it as an irregular bone. Hence, option d is wrong too.
