BIO 121/NRSG201f2018What do I need to know?M3:Axial, Appendicular, Fetal SkeletonsModule 3:Axial, Appendicular and Fetal SkeletonsLearning ObjectivesTo list and discuss several functions of the skeletal systemoSupportoStorage of mineral and lipidsoBlood cell productionoProtectionoLeverageTo identify spongy (cancellous) or compact bone based on gross appearance and location,and to identify distinguishing features of eachTo classify bones into one of four groups based on shapeoClassification by shape, markings and structureoTypes of bonesLong (greater length than width)Short (cube shaped)Flat (thin layers of parallel plates)Irregular (complex shapes)Sesamoid (shaped like a sesame seed)To identify bone markings (ie, foramen, ridge, crest, depression) and describe theirfunctionsoDepressions and openings – allow the passage of soft tissues, form jointsFissure – narrow slit between bones for passage of blood vessels or nervesForamen – hole for passage of blood vessels, nerves or ligamentsFossa – a hollow or depressed areaEx. Olecranon fossa (humerus) always faces posterior; look to seewhich way the head faces (if head is on the left, then it is the righthumerus)Meatus – tube-like passageway or opening; passageway or canal for bloodvessels and nervesoProcesses – projections or outgrowths that form joints, serve as attachment pointsfor tendons and ligamentsProcesses that form jointsCondyle – rounded projection with a smootharticularsurfaceFacet – smooth, flat, slightly concavearticularsurfaceHeadProcesses that form attachment point for connective tissueCrestEpicondyleLineSpinous processTrochanterTubercleTuberosity – variably sized projection with rough, bumpy surface1
BIO 121/NRSG201f2018What do I need to know?M3:Axial, Appendicular, Fetal SkeletonsoEx. Radial tuberosity (radius) always faces anteriorly; lookto see which side the styloid process is on (if styloidprocess is on right, then it is right radius)oEx. Tibial tuberosity (tibia) always faces anteriorly; look tosee which side the medial malleolus is on (if medialmalleolus is on the left, then it is right tibia)oRidgeoNotch – indentation on end of boneEx. Trochlear notch always faces anteriorly; look to see which side theradial notch is on (if radial notch is on right, then it is the right ulna)oCavity – point of attachment for other bones (joint), distinguishing characteristicbetween left/rightEx. Glenoid cavity – holding the scapula with spine posterior and theglenoid cavity is on the right, then it is the right scapula
