Irregular bone
(Redirected from Irregular bones)
Irregular bones are bones in the human body that do not fall into any other category, due to their non-uniform shape. Precise function of these bones is generally determined by their shape, and they primarily consist of spongy bone, with a thin outer layer of compact bone.
Structure[edit | edit source]
Irregular bones are primarily made of spongy bone, also known as cancellous bone, which is characterized by a spongy, honeycomb-like structure. This type of bone is highly vascular and contains red bone marrow. The outer surface of irregular bones is composed of a thin layer of compact bone, also known as cortical bone, which is dense, strong, and durable.
Function[edit | edit source]
The shape of irregular bones often determines their specific function. They primarily serve to protect internal organs, provide support and stability, and aid in movement.
Examples[edit | edit source]
Examples of irregular bones include the vertebrae, sacrum, coccyx, temporal, sphenoid, and ethmoid bones in the skull, and the zygomatic, maxilla, and mandible bones in the face.
