Chapter 7 Flashcards
Axial skeleton:
Skull bones, auditory ossicles (ear bones) hyoid bone, ribs, sternum (breastbone), bones of the vertebral column
Appendicular skeleton:
Bones of the upper and lower limbs (extermities) bones forming the girdles that connect the limbs to the axial skeleton
Sutural bones:
small extra bone plates located within the sutures of cranial bones
Sutures
Jointed areas where flat bones come together
Depressions/Oppenings
Allow the passage of soft tissues and form joints
Processes
Projections or outgrowths that form joints and serve as attachment points for ligaments and tendons
Fissure
Narrow slit between bones for passage of blood vessels or nerves
Foramen
Hole for passage of blood vessels, nerves or ligaments
Fossa
Shallow depression
Sulcas
Furrow/groove on a bone for passage of blood vessels, nerve or tendons.
Meatus
Tubelike openings
Condyle
Rounded projections with a smooth articular surface
Facet
Smooth, flat, slightly concave articular surface
Head
Usually round articular process supported on a neck
Crest
Prominent ridge or elongated process
Epincodyle
Usually roughened projection on a condyle
Line
Long, narrow ridge or border (less prominent than a crest)
Spinous process
sharp, slender projection
Tronchanter
Very large projection found ONLY in the female femur
Tubercle
Variably sized rounded projection
Tuberosity
Variably sized projection with rough bump surface
Paranasal Sinuses
Mucosal membraned-lined cavities in the frontal, maxillary sphenoid and ethmoid bones. Echo voice and increase surface area on teh nasal mucosa
Fontanels
Mesenchyme-filled spaces between cranial bones present at birth. Close up beginning at 6 months of age through 2 years
Hyoid Bone
Supports the tongue by attaching to muscles. Situated at the top of the larynx
