Biology 152 Appendicular Skeleton Anatomy Objectives We will learn proper bone names, left/right/medial, and the parts of bones in this exercise. Start by learning the names of the bones. As you gain comfort with that, learn the parts visually and by feel. If you can put the bone in a bag and still feel and identify the parts, then you really will remember it for the practical! Remember, if there are paired bones in the body, then their parts are likely paired left/right as well. Medial bones could have paired or medial parts. SCAPULA - right/left - ax points down and arm goes off to the side; Glen and Cora are dating! Note that posterior has a ridge and the anterior (deeper side) is smooth. acromion lateral border coracoid process glenoid cavity infraspinous fossa medial border spine of scapula subscapular fossa supraspinous fossa
HUMERUS - right/left - stick shift with overdrive button for your thumb; My Little CTO! Intertubercular groove capitulum (the lateral condyle) coronoid fossa (CTO) deltoid tuberosity greater tubercle lateral epicondyle lesser tubercle medial epicondyle olecranon fossa (CTO) radial fossa trochlea (the medial condyle; CTO) CLAVICLE right/left curves out and back and bump points downwards acromial end sternal end conoid tubercle
ULNA right/ left - has a proximal "U" and points at the pinky; My Little CTO! coronoid process (CTO) olecranon process (CTO) radial notch styloid process (medial) trochlear notch (CTO) RADIUS right/left - the radius rotates and points at the thumb neck radial tuberosity styloid process (lateral) ulnar notch MANUS REGIONS - right/left hand bones identified by position (#1-5 starting at pollex) CARPALS Scaphoid, Lunate, Triquetrum, Pisiform; Trapezium, Trapezoid, Capitate, Hamate ( Some Lovers Try Positions - That They Can't Handle ) METACARPALS numbered 1-5 PHALANGES numbered 1-5 with proximal, intermediate, distal PEDIS REGIONS - right/left foot bones identified by position (#1-5 starting at hallux) TARSALS talus, calcaneus, navicular, medial/intermediate/lateral cuneiforms, cuboid ( The Circus Needs More Interesting Little Clowns ) METATARSALS numbered 1-5 PHALANGES numbered 1-5 with proximal, intermediate, distal
FEMUR right/left - is proximal and back of knee has large notch for cruciate ligaments adductor tubercle intercondylar notch gluteal tuberosity greater trochanter lesser trochanter lateral condyle lateral epicondyle linea aspera medial condyle medial epicondyle neck patellar articulating surface TIBIA right/left - "T" shaped bone that has sharp front and distal bump points at big toe lateral condyle medial condyle medial malleolus tibial tuberosity tibial plateau (or intercondylar eminence) area where cruciate ligaments attach FIBULA - right/left - notch in the back of distal and it points at heel distal lateral malleolus proximal
Patella - right/left outer (lateral) facet is always wider when you point the apex down medial facet lateral facet COXAL right/left - grab like a gun (finger in greater sciatic notch) and curves medial at front acetabulum anterior inferior iliac spine anterior superior iliac spine posterior inferior iliac spine posterior superior iliac spine crest of ilium (iliac crest) greater sciatic notch lesser sciatic notch ilium
ischium ischial spine ischial tuberosity obturator foramen pubic symphysis (articulated pelvis only) pubis sacroiliac articulating surface On the practical itself, you will be given the following format: POSITION - 0.5 points each STRUCTURE NAME 1 point ea. BONE NAME(S) 0.5 pnts. ea. 1 left right medial of the 2 left right medial of the 3 left right medial of the
