Textbook Question

The unpaired facial bones include the:
(a) Lacrimal and nasal
(b) Vomer and mandible
(c) Maxilla and mandible
(d) Zygomatic and palatine

Verified step by step guidance

Step 1: Understand the question. The problem is asking about the unpaired facial bones in the human skull. Facial bones are part of the skull and are categorized as either paired (occurring on both sides of the face) or unpaired (occurring as a single bone).

Step 2: Recall the unpaired facial bones. In human anatomy, the unpaired facial bones are the vomer and the mandible. These bones are unique because they do not have a counterpart on the opposite side of the face.

Step 3: Analyze the options provided. Look for the pair of bones in the options that match the unpaired facial bones: (a) lacrimal and nasal, (b) vomer and mandible, (c) maxilla and mandible, (d) zygomatic and palatine.

Step 4: Eliminate incorrect options. The lacrimal, nasal, maxilla, zygomatic, and palatine bones are all paired bones, meaning they occur on both sides of the face. This eliminates options (a), (c), and (d).

Step 5: Confirm the correct answer. The vomer and mandible are the only unpaired facial bones, making option (b) the correct choice.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Facial Bones

Facial bones are the bones that form the structure of the face. They include both paired and unpaired bones, with the latter being singular in the human skull. Understanding the classification of these bones is essential for identifying which bones are unpaired, as they contribute to the overall anatomy and function of the facial structure.

Unpaired Facial Bones

Unpaired facial bones are those that do not have a corresponding bone on the opposite side of the face. In the human skull, the primary unpaired facial bones are the mandible and vomer. Recognizing these bones is crucial for answering questions related to facial anatomy and their roles in functions such as breathing and chewing.

Bone Classification

Bone classification in anatomy divides bones into categories such as paired and unpaired, based on their symmetry and presence in the skull. This classification helps in understanding the structure and function of the skeletal system. In the context of the question, it is important to differentiate between paired bones, which occur in sets, and unpaired bones, which stand alone.
