- 1Proximal Part of limbcontains a single bone with a rounded head; allow wide range of movement
- 2Girdlesupports each limb; each has a rounded, cuplike depression (socket) in which the head of proximal part of each limb bone lies
- 3Distal part of each limbcontains two bones connected by an interosseous membrane.
- 4Interosseous membranekeeps the bones a fixed distance apart and allows these bones to pivot about one another (more limited in lower limb)
- 5Styloid processes of radius and ulna =malleoli of tibia and fibula
- 6Both hand and foot have how many metacarpals/tarsals?5
- 7How many phalanges?14
- 8Pectoral girdle contains..-humerus
-clavicle
-scapulae - 9Acromial end of clavicle contains what?coronoid tubercle
- 10Sternal end o clavicle contains?costal tuberosity
- 11Scapula
- 12Components of the upper limb- brachium (arm)
- Antebrachium (forearm)
- hand - 13Bones of the upper limb- 1 humerus
- 1 radius and 1 ulna
- 8 carpal bones
- 5 metacarpal bones
- 14 phalanges - 14What does humerus proximal end articulate with?Glenoid cavity of scapula
- 15In humerus, what is positioned lateral to head?greater tubercle
- 16Humerus; Lesser tuberclesmaller and more medial to head
- 17Humerus; intertubercular sulcusdepression containing tendon of long head of biceps bracii muscle
- 18Humerus; anatomical neckgroove marking location of former epiphyseal plate
- 19Humerus; Surgical necknarrowing immediately distal to the tubercles, fractures easily
- deltoid tuberosity --> deltoid muscle attachment - 20Humerus; radial groovelocation of radial nerve and some blood vessels
- 21Humerus; Medial and lateral epicondylesprovide surfaces for muscle attachment, palpated on sides of elbow
- ulnar nerve travels posterior to medial epicondyle "funny bone" - 22Humerus distal end with 2 curved surfaces- articulate w bones of forearm
- capitulum located laterally (articulates with radius)
- Trochlea located medially (articulates w trochlear notch of ulna) - 23Radius and ulna form?forearm
- bones are parallel
- radius located laterally - 24What are the humerus's 3 depressions- radial fossa: anterolaterally placed ; accommodates radial head
- coronoid fossa: anteromedially placed ; accommodates coronoid process of ulna
- olecranon fossa : posteriorly placed ; accommodates olecranon of ulna when elbow is extended - 25What shape is the radius's head at proximal end?disc shaped: articulates with capitulum of humerus
- 26Where does radius narrow neck extend from?Head to radial tuberosity
- attachment site for biceps brachii muscle - 27What curves slightly in radius?shaft
- 28What process does radius coontainstyloid process at distal end
- 29What notch is located on radius's distal medial surface?ulnar notch: articulates with medial surface of distal ulna
- 30Ulna is ____ compared to radiuslonger, and medially placed bone of the forearm
- 31What shape notch at proximal end of ulna?C- shaped trochlear notch : interlocks with trochlea of the humerus
- 32Olecranonprojection on posterosuperior trochlear notch
- forms posterior bump of elbow - 33Coronoid processinferior lip of trochlear notch
- articulates with humerus - 34Tuberosity of Ulnaat proximal end of bone
shaft terminates in knoblike head - 35Posteromedial styloid processmay be palpated on medial side of wrist
- 36Border between radius and ulnainterosseous border; facing each other
- 37Radius and ulna connected by what type of membraneinterosseous membrane
(dense regular CT; keep them a fixed distance apart)
- pivot of rotation for the forearm - 38Supinationanatomical position
- radius lateral and ulna medial - 39Pronationpalm facing down
radius still on lateral side of elbow
- distal end of radius has crossed over
- more medial structure - 40Carrying angle
