Irregular bones
Irregular Bones
Irregular bones are a specific category of bones in the human skeleton that do not fit into any other category due to their complex shape. Unlike long bones, short bones, and flat bones, irregular bones cannot be classified based on their shape or size.
Pronunciation
Irregular bones: /ɪˈrɛɡjʊlər boʊnz/
Etymology
The term "irregular bones" comes from the Latin word "irregularis", meaning "not regular", and the Old English word "ban", meaning "bone".
Description
Irregular bones are primarily made up of spongy bone, with a thin outer layer of compact bone. They have more complex shapes, like the vertebrae that support the spinal cord and the bones of the skull that protect the brain.
Examples
Some examples of irregular bones include the vertebrae, sacrum, coccyx, temporal bone, sphenoid bone, ethmoid bone, zygomatic bone, maxilla, mandible, palatine bone, inferior nasal concha, and hyoid bone.
