Chapter 6 Flashcards
Surface features, can yield an abundance of anatomical information.
Bone Markings
The shaft of a long bone.
Diaphysis
The head of a long bone.
Epiphysis
The region of a long bone between the epiphysis and diaphysis, corresponding to the location of the epiphyseal cartilage of the developing bone.
Metaphysis
The space within a bone that contains the marrow.
Medullary Cavity
The outer layer or portion of an organ or bone.
Cortex
Calcium phosphate interacts with calcium hydroxide to form crystals of this.
Hydroxyapatite
A bone cell responsible for the maintenance and turnover of the mineral content of the surrounding bone.
Osteocytes
Concentric layers; the concentric lairs of bone within an osteon.
Lamellae
Microscopic passageways between cell.
Canaliculi
A cell that produces the fibers and matrix of bone.
Osteoblasts
The process of producing new bone matrix.
Osteogenesis
The organic matrix before calcium salts are deposited.
Osteoid
A cell that dissolves the fibers and matrix of bone.
Osteoclasts
The basic histological unit of compact bone, consisting of osteocytes organized around a central canal and separated by concentric lamellae.
Osteon
A connective tissue partition that subdivides an organ.
Trabeculae
Responsible for blood cell formation.
Red Bone Marrow
Adipose tissue important as an energy reserve.
Yellow Bone Marrow
The layer that surrounds a bone, consisting of an outer fibrous region and inner cellular region.
Periosteium
An incomplete cellular lining on the inner surfaces of bones.
Endosteum
The formation of bone.
Ossification
The deposition of calcium salts within a tissue.
Calcification
The conversion of a cartilaginous model to bone.
Endochondral Ossification
The cartilage pad that covers the surface of a bone inside a joint cavity.
Articular Cartilage
The cartilaginous region between the epiphysis and the diaphysis of a growing bone.
Epiphyseal Cartilage
The former location of the epiphyseal cartilage is detectable in x-rays is known as this. It remains after epiphyseal growth has ended.
Epiphyseal Line
The organic and mineral components of the bone matrix are continuously being recycled and renewed through this process.
Remodeling
A large blood clot.
Fracture Hematoma
An enlarged collar of cartilage and bone, forms and encircles a bone tat the level of the fracture.
External Callus
Organizes within the medullary cavity and between the broken ends of the shaft.
Internal Callus
When the reduction in bone mass is sufficient to compromise normal function.
Osteoporosis
Inadequate ossification is called _____, and all of us become slightly _____ as we age.
Osteopenia
