Bones Flashcards
Long Bone - structure
Tubular
Short Bone - structure
Cuboidal - only found in ankle and wrist
Flat Bone - function
Protective
Irregular bone - structure
Various shapes
Sesamoid Bone - function
Protect tendons from wear
Body
Principle mass of bone; shaft of long bone
Capitulum
Small, round, articular head
Condyle
Rounded, knuckle-like, articular area
Crest
Ridge
Epicondyle
Eminence superior or adjacent to condyle
Facet
Smooth, flat area
Foramen
Passage, opening in bone
Fossa
Hollow or depressed area
Groove
Elongated depression
Head
Large, rounded articular head
Line
Linear elevation, “ridge”
Malleolous
Rounded process
Neck
Narrow portion proximal to head
Notch
Indentation at edge of bone
Process
Extension/projection
Protuberance
Bulge/projection
Shaft
Diaphysis, or body of long bone
Spine
Thorne-like process
Trochanter
Large, blunt elevation
Trochlea
Process that acts like a pulley
Tubercle
Small, raised eminence
Tuberosity
Large, rounded elevation
Intramembranous Ossification
Mesenchymal models of bones form during embryonic period; direct mesenchyme begins in fetal period.
Endochondral Ossification
Cartilage models of bone form from mesenchyme during fetal period; bone then replaces cartilage.
Diaphysis
Primary ossification center; grows as bone develops
Epiphyses
Part of the bone ossified
Metaphysis
Flared part of the diaphysis, closest to the epiphyses
Epiphysial Plate
Cartilaginous; intervene between diaphysis and epiphyses
Epiphysial Line
Seam formed during fusion process; dense
Blood reaches osteocytes in compact bone via __________.
Haversian System
The periosteum is richly supplied with sensory nerves - ___________- that carry pain fibers.
Periosteal Nerves
Within bones, __________ cause constriction or dilation of blood vessels, regulating blood flow through bone marrow.
Vasomotor Nerves
