The joint between the frontal and parietal bones is correctly called the ____ suture.
(a) Parietal
(b) Lambdoid
(c) Squamous
(d) Coronal

검증된 단계별 안내

Step 1: Identify the bones involved in the joint. The problem states the joint is between the frontal bone and the parietal bone.

Step 2: Recall the names of sutures in the skull. Sutures are fibrous joints that connect the bones of the skull.

Step 3: Understand that the suture between the frontal bone and the parietal bones is called the coronal suture because it runs across the top of the skull like a crown (corona means crown).

Step 4: Review the other options: the parietal suture is not a standard term; the lambdoid suture connects the parietal bones to the occipital bone; the squamous suture connects the parietal bone to the temporal bone.

Step 5: Conclude that the correct name for the suture between the frontal and parietal bones is the coronal suture.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Cranial Sutures

Cranial sutures are fibrous joints connecting the bones of the skull. They allow for growth during development and fuse as a person ages. Understanding the names and locations of these sutures is essential for identifying specific bone connections.

Frontal and Parietal Bones

The frontal bone forms the forehead and the front part of the skull, while the parietal bones are located on the sides and top of the skull. Knowing their positions helps in identifying the suture that connects these two bones.

Coronal Suture

The coronal suture is the joint that connects the frontal bone to the two parietal bones across the top of the skull. It runs horizontally from one side of the skull to the other, making it the correct answer for the suture between these bones.

The joint between the frontal and parietal bones is correctly called the ____ suture.(a) Parietal(b) Lambdoid(c) Squamous(d) Coronal
