Page 1 Bone Lists OSTEO Final No sternal connection Ribs: PAGE 2 General Rib Features: a. Head o MUST Side Ribs (310): Find sternal end of b. Tubercle (bump near head) rib and hold it parallel c. Neck (below head) to ground and away d. Angle (just before neck and from you head) Head must be higher e. Shaft (area of rib between tha sternal end Neck and Sternal End) Costal Groove on f. Costal Groove (groove on bottom innerside of rib) g. Sternal End (weird notch Clavicle: where attaches to sternum) Unique First and Second Rib I. Clavicle Features: Feature : a. Sternal End h. Groove for subclavian artery b. Acromial End c. Costoclavicular Impression and vein (first; next to Scalene Tubercle) (small impression on sternal i. Tubercle for Scalene Muscle end) (first; tiny bump on inner d. Conoid Tubercle (small side of shaft) bump next to Trapezoid j. Tuberosity for Serratus Line) Anterior Muscle (Second; e. Trapezoid Line (line going bump above costal groove) from Acromial End to o Conoid Tubercle) o Ribs 17 (including 1 & 2) f. Subclavian Groove (groove inferior on Clavicle) are “True Ribs” g. Nutrient Foramen (opens toward sternal end – vessel Each has cartilage usually enters bone toward connection to sternum the first epiphysis to appear/unite) o Ribs 810 are “False Ribs” Connected to coastal cartilage of “True II. Siding Clavicle (Easier One to Rib” above Do): A. Find acromial (flat end) o Ribs 11 & 12 are “Floating B. Hold acromial end to Ribs” outer shoulders 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) Scapula Glenoid Fossa (large depression where humerus 7 ossification centers connects) articulates with acromial end of clavicle and humerus II. Anterior Side: o you can tell side by spine pointing backwards and Oblique Lines (horizontal glenoid fossa pointing ridges along anterior side of outwards scapula) Subscapular Fossa (entire flat Scapular Features: surface on anterior side) I. Posterior Side: Siding: Scapular Spine turns into Glenoid Fossa (giant socket for Acromian Process (large arm) must point laterally process on back) Scapular Spine (easily Coracoid Process is anterior distinguishable spine/ridge and lateral near acromian running to process pointing Infraspinous Fossa and back) Supraspinous Fossa (depressions above and below spine) Humerus Lateral Border (outer edge); Superior Border (edge Anterior Side: between superior angle and o Humeral Head (large scapular notch) ball connecting to Inferior Angle (angle at scapula) o Surgical Neck (goes bottom of scapula) and Superior Angle (angle above around bottom of supraspinous fossa) humeral head; not really distinct) o Anatomical Neck (goes fits when elbow is above greater tubercle extended) and around the top of the o Coronoid Fossa (fossa humeral head) directly above trochlea) o Greater Tubercle (large o Ulna Nerve Groove bump on lateral side of (groove between medial humerus next to neck) epicondyle and trochlea o Lesser Tubercle (more where nerve runs) medial and points out further) SIDING: o Lateral and Medial Supracondylar Crest o Head pointing in (crests on edge of o Medial epicondyle (longer/ Humerus) “larger” one) pointing in o Deltoid Tuberosity (bump on lateral side near Trochlea) Radius & Ulna Posterior Side: Supination – correct position (palms up); ulna medial & o Lateral Epicondyle (large bump lateral to radius lateral Trochlea) o Medial Epicondyle Pronation – opposite; ulna & (larger bump medial of radius twist so palm faces downwards Trochlea; points 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 o Radial Fossa (fossa on elbow is extended lateral side above Articulates distally with capitulum where radius Lunate and Scaphoid Ulna Shaft Shape: Proximal End is round A. 3 oss. centers (Olecranon Process, Turns teardrop shaped because of Diaphysis, Head) Interosseous Crest B. Nutrient Foramen in midshaft Distal end is smooth anteriorly and 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 a) Rectangle proximately CAPITULUM and round) b) Triangular at midshaft Radial Tuberosity (medial and c) Round distally just below radial head/neck) Radial Neck (skinny, smooth, Ulna Features: round area directly below the 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 Trochlea; points outwards from middle and medial where ulna would of bone) fit) Nutrient Foramen (tiny H. Radial Notch (small notch on lateral of coronoid process; radial head rests here) foramen near interosseous crest I. Ulnar Tuberosity (bump below going towards radial head) coronoid process) Radial Styloid Process J. Nutrient Foramen (usually single, sometimes multiple) (articulating with carpals; K. Ulnar Styloid Process (points pointy part distal and lateral) Dorsal Tubercle (bump(s) on backwards; on Ulnar Head) L. Styloid Process (process on back of posterior of Radius; distal) ulna) M.
