* '''canaliculi''' - (singular, canaliculus) small channel in the bone matrix in which an osteocyte process lies and communicates with other osteocytes and the Haversian canal. Allow osteocytes to communicate with each other and to exchange substances by diffusion. | * '''canaliculi''' - (singular, canaliculus) small channel in the bone matrix in which an osteocyte process lies and communicates with other osteocytes and the Haversian canal.

* '''desmal ossification''' - ({{intramembranous ossification}}) the process of mesenchyme directly ossifying into bone without a pre-existing cartilage template. Vascularised regions of mesenchymal cells proliferate and differentiate into pre-osteoblasts and then osteoblasts, occurs in parts of the skull and the clavicle. | |||

* '''Howship's lacuna''' - (resorptive bay) the historic name for the shallow bay or cavity lying directly under an osteoclast. This is the site of bone matrix resorption. Named after John Howship (1781–1841) a British anatomist who identified this region in 1820. | * '''Howship's lacuna''' - (resorptive bay) the historic name for the shallow bay or cavity lying directly under an osteoclast.
