The functions of osteons, bone marrow, osteocytes, canaliculus, lamella, periosteum

Osteons

The basic unit of structure in adult compact bone, consisting of a central (Haversian) canal with its arranged lamellae,lacunae, osteocytes, and canaliculi. Also called Haversian system

Bone marrow

• A spongy substance found it the center of the bones (medullary cavity)

• Contains stem cells that produce blood cells and the cells that make up the immune system

Osteocytes

Located in the lacunae, these are mature osteoblasts, which monitor and maintain the bone matrix

Canaliculus

Tiny canals and they radiate from each lacuna and connect with the central canal

Lamella

A thin layer

Periosteum

-Is composed of two layers: an outer fibrous layer that serves as an attachment site for tendons and ligaments and an inner layer that contains specialized cells involved in bone growth, repair, and remodeling

-is a sheath that covers bones and contains blood vessels and nerves that provide nourishment and sensation to the bone
