Which bone forms by intramembranous ossification?Multiple ChoiceRadiusHamateAxisZygomatic

Break Down the Problem

1. Identify the type of ossification: Intramembranous ossification is a process where bone develops directly from mesenchymal tissue.
2. Consider the options: The options presented are Radius, Hamate, Axis, and Zygomatic.

Relevant Concepts

1. Types of Bones: Intramembranous ossification typically occurs in flat bones of the skull and certain facial bones.
2. Understanding Each Option:
   • Radius: A long bone in the forearm, formed by endochondral ossification.
   • Hamate: A wrist bone, typically formed via endochondral ossification.
   • Axis: The second cervical vertebra, formed by endochondral ossification.
   • Zygomatic: A facial bone that is known to develop through intramembranous ossification.

Analysis and Detail

• Zygomatic Bone: This bone is also known as the cheekbone and is a key component of the facial skeleton. It is formed through intramembranous ossification, which means it arises directly from mesenchymal connective tissue without a cartilage intermediate.

Verify and Summarize

• Conclusion from Analysis: The zygomatic bone is the only one among the options that forms through the process of intramembranous ossification. The others are all formed through endochondral ossification.

Final Answer

Zygomatic forms by intramembranous ossification.
