osseuse

Osseuse is a French adjective meaning pertaining to bone. In English, the corresponding term is osseous. The term is used to describe bone tissue and structures derived from bone, as in osseous tissue, or osseous features.

Bone tissue (osseous tissue) is a dynamic, living tissue composed of a mineralized extracellular matrix and cells. The matrix consists largely of collagen type I and hydroxyapatite crystals, which confer strength and rigidity. The cellular component includes osteoblasts, osteocytes, and osteoclasts, organized within bone as compact (cortical) bone and cancellous (trabecular) bone. The outer layer is covered by the periosteum, while the inner surfaces are lined by the endosteum.

Bone formation occurs by intramembranous ossification or endochondral ossification. Remodeling maintains mineral homeostasis and mechanical integrity, driven by osteoblasts building matrix and osteoclasts resorbing it. Blood supply and innervation sustain growth and healing.

Functions: structural support, protection of organs, leverage for movement, mineral storage (calcium, phosphate), and hematopoiesis in red bone marrow.

Clinical notes: changes in osseous tissue form disease states such as osteoporosis (reduced density) or osteopetrosis (increased density). Fracture healing involves a callus of new osseous tissue. Pathological ossification may occur in soft tissues (heterotopic ossification).

Usage: in French, feminine form "osseuse" modifies feminine nouns (surface osseuse, crête osseuse).
