Bones & Processes Flashcards
Somewhat cube like bone with lengths and widths equal
Examples
Short bones
Bones of wrists and ankles
Bone with Long longitudinal axes and expanded ends.
Examples:
Long bone
Femur phalanges radius ulna
Plate like bones with broad surfaces
Examples
Flat bone
Ribs scapula sternum
Bones in a variety of shapes
Example
Irregular bones
Vertebral column
Small and nodular bones
Example
Sesamoid (Round) bones
Knee cap
Found at each end of a long bone expanded portion
Articulates (forms a joint)
Epiphysis
Shaft of the bone between epiphyses
Diaphysis
Tough vascular covering of fibrous tissue completely encloses the bone except for the articular cartilage
Function: helps form & repair bone tissue
Periosteum
Provides sites where ligaments & tendons attach (process)
Boney projections
Form passages for blood vessels & nerves (process)
Groves & openings
May articulate with process of another (process)
Bone depressions
This type of bone makes up the wall of the diaphysis
Compact bone
Epiphysis is largely composed of ____ tissue
Spongy bone (cancellous)
Hollow tube within the diaphysis
Marrow / Medullary Cavity
A band of hyaline cartilage in growing bone. Includes layers of young chondrocytes undergoing mitosis & causing bone to grow
Epiphyseal plate
Rounded smooth articular surface (joint)
Condyle
Small flattened surface
Facet
Soft spot on the skull
Fontanel
Hole ( nerves blood vessels ligaments travel thru)
Foramen
Deep depression
Fossa
Tube like passage way within a bone
Meatus
A prominent projection
Process
Cavity within a bone
Sinus
Interlocking line of union between bones
Suture
Knob like process ; bump
Tubercle
(Process) small opening which blood vessels and nerves pass to the forehead tissue
Supraorbital foramen
Process. Reduce skull weight and increase intensity of voice by serving as a resonant sound chamber
2 frontal sinuses
Process. One on each side of skill. Form bulging sides of the cranium.
Parietal bones
Where the parietal and occipital bones meet
Lambdoid suture
Process. Articulate with 1st vertebrae (atlas)
Occipital condyle
Process. Attachment site for neck muscles. Less pronounced on women
Occipital protuberance
On each side of skull.
Temporal bones
Temporal bones meet parietal along which suture
Squamous
Process. Attachment for muscles of neck
Mastoid process
BOOB ON EAR
Creates prominence of cheek
Zygomatic process
Forms base of cranium, sides of skull, and floors and sides of orbits
Sphenoid bone
Saddle shaped process. Occupied by pituitary gland
Sella turcica
Separates brain and nasal cavity
Ethmoid bone
Thin bone. Makes up part of roof of nasal cavity. Holes allow scent nerves to pass to brain
Cribriform plate (has holes)
Forms most of nasal septum
Perpendicular plate
Membranes that enclose the brain (meninges) attach to this
Crista galli
