Front

What is a joint?

Back

A joint is the place where two bones meet, allowing for movement and flexibility.

Front

Front

What is the function of the vertebrae?

Back

The vertebrae protect the spinal cord and provide structural support for the body.

Front

What is the difference between the axial and appendicular skeleton?

Back

The lambdoidal suture is the fibrous joint that connects the occipital bone with the parietal bones of the skull.

Front

What are osteons?

Back

Osteons, or Haversian systems, are the structural units of compact bone, consisting of concentric layers of bone matrix and a central canal.

Front

What is the role of lamellae in bone structure?

Back

Lamellae are thin layers of bone matrix that form the structure of osteons and provide strength to the bone.

Front

What is the occipital bone?

Back

The occipital bone is a cranial bone located at the back of the skull, which houses the foramen magnum and protects the brain.
