Question

When looking at the lateral view of the skull, which of the following options include three bones that articulate with the parietal bone?

a. Frontal, occipital, and sphenoid bones
b. Occipital, temporal, and maxillary bones
c. Temporal, sphenoid, and ethmoid bones
d. Occipital, temporal, and frontal bones

Answer 1

Option d, which lists the Occipital, temporal, and frontal bones, is the correct trio of bones that articulate with the parietal bone in the lateral view of the skull.

Step-by-step explanation:

The correct option that includes three bones that articulate with the parietal bone when looking at the lateral view of the skull is option d: Occipital, temporal, and frontal bones.

The parietal bones form part of the cranial cavity, which surrounds and protects the brain. Each parietal bone joins anteriorly with the frontal bone through the coronal suture, inferiorly with the temporal bone through the squamous suture, and posteriorly with the occipital bone through the lambdoid suture. These articulations are crucial for the structural integrity of the skull.

While the sphenoid and ethmoid bones are also part of the brain case, they do not directly articulate with the parietal bones in the lateral aspect view of the skull as depicted in the question. Hence, option d is the direct answer that reflects the correct articulations of the parietal bone.
