Page 1 No sternal connection Ribs o MUST side Ribs (310): General Rib Features: a. Head Find sternal end of rib and hold it parallel b. Tubercle (bump near head) to ground and away c. Neck (below head) from you d. Angle (just before neck and Head must be higher head) tha sternal end e. Shaft (area of rib between Costal Groove on Neck and Sternal End) bottom f. Costal Groove (groove on innerside of rib) Clavicle: g. Sternal End (weird notch where attaches to sternum) I. Clavicle Features: Unique First and Second Rib a. Sternal End Feature : b. Acromial End h. Groove for subclavian artery c. Costoclavicular Impression (small impression on sternal and vein (first; next to end) Scalene Tubercle) i. Tubercle for Scalene Muscle d. Conoid Tubercle (small (first; tiny bump on inner bump next to Trapezoid side of shaft) Line) j. Tuberosity for Serratus e. Trapezoid Line (line going Anterior Muscle (Second; from Acromial End to bump above costal groove) Conoid Tubercle) o f. Subclavian Groove (groove o Ribs 17 (including 1 & 2) inferior on Clavicle) g. Nutrient Foramen (opens are “True Ribs” toward sternal end – vessel usually enters bone toward Each has cartilage the first epiphysis to connection to sternum appear/unite) o Ribs 810 are “False Ribs” Connected to coastal II. Siding Clavicle (Easier One to cartilage of “True Do): Rib” above A. Find acromial (flat end) B. Hold acromial end to o Ribs 11 & 12 are “Floating outer shoulders Ribs” a) The arc Infraglenoid Tubercle (bump protruding directly below socket for outwards clavicle; very hard to identify should be sometimes!!!!) Supraglenoid lateral Tubercle (bump directly above socket) Glenoid Fossa (large Scapula depression where humerus connects) 7 ossification centers articulates with acromial end of II. Anterior Side: clavicle and humerus o you can tell side by spine Oblique Lines (horizontal pointing backwards and ridges along anterior side of glenoid fossa pointing scapula) outwards Subscapular Fossa (entire flat surface on anterior side) Scapular Features: Siding : I. Posterior Side: Glenoid Fossa (giant socket for Scapular Spine turns into arm) must point laterally Acromian Process (large Scapular Spine (easily process on back) distinguishable spine/ridge Coracoid Process is anterior running to process pointing and lateral near acromian back) Infraspinous Fossa and Supraspinous Fossa (depressions above and below Humerus spine) Lateral Border (outer edge); Anterior Side: Superior Border (edge between superior angle and o Humeral Head (large scapular notch) ball connecting to scapula) Inferior Angle (angle at bottom of scapula) and o Surgical Neck (goes Superior Angle (angle above around bottom of supraspinous fossa) humeral head; not really o Radial Fossa (fossa on distinct) lateral side above o Anatomical Neck (goes capitulum where radius above greater tubercle fits when elbow is and around the top of the extended) humeral head) o Coronoid Fossa (fossa o Greater Tubercle (large directly above trochlea) bump on lateral side of o Ulna Nerve Groove humerus next to neck) (groove between medial o Lesser Tubercle (more epicondyle and trochlea medial and points out where nerve runs) further) o Lateral and Medial SIDING : Supracondylar Crest (crests on edge of o Head pointing in Humerus) o Medial epicondyle (longer/ o Deltoid Tuberosity “larger” one) pointing in (bump on lateral side near Trochlea) Radius & Ulna Posterior Side: Supination – correct position o Lateral Epicondyle (palms up); ulna medial & (large bump lateral to radius lateral Trochlea) o Medial Epicondyle Pronation – opposite; ulna & (larger bump medial of radius twist so palm faces Trochlea; points downwards outwards from middle of Humerus) Radius o Anterolateral Surface (surface posterior and 3 oss. Centers diaphysis and closer to head) epiphysis o Capitulum (bump Medial of Ulna lateral to trochlea) Nutrient Foramen in midshaft o Trochlea (two bumps Head articulates with with groove in middle Capitulum of Humerus and where elbow is) rests in Radial Fossa when elbow is extended Ulnar Notch medial Articulates distally with Lunate and Scaphoid Ulna Shaft Shape: Proximal End is round A. 3 oss. centers (Olecranon Process, Turns teardrop shaped because of Interosseous Crest Diaphysis, Head) Distal end is smooth anteriorly and B. Nutrient Foramen in midshaft C. Articulates with Trochlea (radius at rough posteriorly distal end) D. Fits into Olecranon Fossa (elbow Features of Radius: extended) or Coronoid Fossa (elbow flexed) E. Shaft Shape: Radial Head (articulates with CAPITULUM and round) a) Rectangle proximately Radial Tuberosity (medial and b) Triangular at midshaft c) Round distally just below radial head/neck) Radial Neck (skinny, smooth, round area directly below the Ulna Features: Radial Head F. Olecranon (large, curved part above Interosseous Border (medial deep depression articulating with crest/edge) trochlea) Ulnar Notch (notch of back G. Coronoid Process (below depression for and medial where ulna would Trochlea; points outwards from middle fit) of bone) H. Radial Notch (small notch on lateral of Nutrient Foramen (tiny coronoid process; radial head rests here) foramen near interosseous crest I. Ulnar Tuberosity (bump below going towards radial head) coronoid process) J. Nutrient Foramen (usually single, Radial Styloid Process (articulating with carpals; sometimes multiple) pointy part distal and lateral) K. Ulnar Styloid Process (points Dorsal Tubercle (bump(s) on backwards; on Ulnar Head) L. Styloid Process (process on back of posterior of Radius; distal) ulna) M. Trochlear Notch (large notch created by Olecranon Process where trochlea fits SIDING : creating the elbow) Radial styloid process distal w/ SIDING: it pointing laterally Furrow is Radial Notch medial palmar Processlike Olecranon proximal part is medial Single art. For trapezium Carpals Double art. for MC3 (smooth and on ends of MC) https://quizlet.com/_27hrfu o MC3 Skinny metacarpals phalanges hamate trapezoid/triangular capitate quizlet shaped art. surface Styloid is dorsal and lateral Scaphoid (Scary) Double artics. w/ Lunate (Losers) Triquetral (Tri) MC2 (laterally) & Trapezium (Trapping) MC4 (medially) Trapezoid (Zoids) o MC4 Proximal articulate Capitate (Currently) Hamate (hey) surface is rectangular and has weird ugly HAMULUS circles laterally Articulation for MC3 (two little circles [on lateral side]) One long articulation for MC 5 (facing medially) o MC5 Prox. Art. is square Metacarpals 1 sidde art. for MC4 SIDING: (laterally) No medial art. Smooth side dorsal; ridged palmar Os Coxae o MC1 Pollex (Thumb) Pectoral vs. Pelvic Girdles Short & Thick Os Coxae: 1 articulation o Fused from ilium, ischium, o MC2 and pubis (NEED TO Index KNOW WHERE THESE Prox. Artic. Is ARE) triangular w/ a deep Ischium and pubis furrow form at 67 years Fuse in acetabulum Greater Trochanter – lateral starting at 12 and ending at 18 large bump next to neck and Articulate with each head other at Pubic Lesser Trochanter – another Symphasis and large but smaller medial and sacrum at Auricular just below neck and head Surface Intertrochanteric Line – line o Hips modified for obligate bipedalism (reposition gluteal running vertically on neck on muscles for balance) posterior Much wider and Intertrochanteric Crest – larger for women crest running from greater trochanter to lesser trochanter Linea Aspera – posterior ridge running down proximal end of femur Femur Nutrient Foramen – posterior and proximal just before linea Largest bone in the body aspera One primary ossification center Medial/Lateral Condyle – (diaphysis) and 4 secondary centers smooth surface articulating (3 prox: head, greater trochanter, with Patella/Tibia lesser trochanter; 1 distal: condyles) medially/laterally Bipedalism in humans Medial Supracondylar Line – line that splits from linea aspera SIDING (Another Easy One): on posterior of femur and runs Femoral Head inwards medially to the adductor tubercle Patellar forwards Medial/Lateral Epicondyle – Femur Features: large bump distally on femur and medial/lateral next to medial/lateral condyle Femoral Head – large ball attached to Acetabulum Popliteal Surface – flat surface Fovea Capitis – tiny distal and posterior on femur between condylar lines just depression on top of head that attaches a ligament to above intercondylar fossa acetabulum Adductor Tubercle – on medial side distal on femur just Femoral Neck – giant neck under head above epicondyle connecting to medial supracondylar line Intercondylar Notch – posterior side of femur; large notch on back of knee Patellar Surface – smooth surface anteriordistal on femur where patella (knee) rests Tibia Patella One primary oss. Center (diaphysis) Sesamoid Bone – develops w/i a 2 secondary (each epiphysis) tendon Plateau is superior and malleolus is Apex – (from anterior view) rough medial surface (w/ many holes) from the articular facets to anterior side Larger bone of lower leg (tibia vs Medial/Lateral Articular Facet – fibula) deeper/(wider&flatter); a smooth depression that articulates with Medial/Lateral Condyle Base – proximal part of Patella that flattens horizontally
