Bone and Oral Histology

Flashcards covering key terms and concepts from bone structure and oral histology.

Osteoblasts

Bone cells that are responsible for bone formation.

Osteoclasts

Bone cells that are responsible for bone resorption.

Osteocytes

Mature bone cells that maintain bone tissue.

Osteoprogenitor cells

Stem cells that differentiate into osteoblasts.

Howship's lacuna

Depressions in bone surface where osteoclasts resorb bone.

Compact bone

Dense bone that forms the outer layer of bones.

Spongy bone

Lightweight, porous bone found inside bones.

Medullary cavity

Space within the bone that contains bone marrow.

Periosteum

Outer fibrous layer surrounding the bone.

Haversian system (Osteon)

Structural unit of compact bone formed by concentric lamellae.

Keratinized stratified squamous epithelium

Type of epithelium found in areas subject to friction, such as skin.

Parakeratinization

Process where the stratum corneum retains nuclei, indicating incomplete keratinization.

Non-keratinocytes

Cells in the epithelium that do not produce keratin.

Desmosome

Cell junction that Links adjoining cells to resist mechanical stress.

Basement membrane

Thin layer that anchors epithelium to underlying connective tissue.

Filiform papillae

Thread-like structures on the tongue providing texture and grip.

Taste bud

Sensory structures in the oral cavity responsible for the sense of taste.

Masticatory mucosa

Dense, keratinized mucosa found in areas subjected to mechanical forces.

Mixed salivary gland

Gland that contains both serous and mucous cells.

Eruption

Process by which teeth emerge through the gum line.

Odontoclast

Cell responsible for the resorption of tooth structure during shedding.
