Arm bones Flashcards
Parts of scapula
Subscapularis fossa glenoid fossa Coracoid process Acronion Intraspinatus fossa Supraspinatus fossa
Parts of the clavicle
Sternal to acromial end
Impression of costeoclavicular
Coronoid ligament
Trapezoid line
Proximal end of humerus proximal
Head
lesser tubercle
greater tubercle- more lateral
surgical neck
Distal end
Capitulum- articulates with radius trochlea-articulates with ulna Coronoid fossa Radial fossa Medial epicondyle- medial and ulna nerve pass over
Joints of shoulder
Glenohumeral
Sternoclavicular
acromiaclavicular
Joints of elbow
Radial head and capitulum
Trochlear notch and head of ulna
Wrist joint
Radial facet with scaphoid and lunate
Ulna not part of it
Radialulnar joint
Radial notch- head of radius and ulna notch
Ulna notch- radial notch and ulna head
Carpal bones
Sacphoid lunate traquestrium pisaform Trapezium trapezoid capitate hamate
deltoid tuberosity
lateral rough deltoid muscle attaches to on humerus
Radial groove
Shallow depression, runs down posterior surface
radial nerve and profundo brachii
Ulna proximal
Olecronn
Trochlear notch- articulates with trochlear of humerus
Coronoid process- projects anteriorly
Radial notch- lateral surface which articulates with head of radius
Ulna distal
head articulates with the ulnar notch of the radius to form the distal radio-ulnar joint
Radius proximal
Head of radius- disc , concave articulating surface allowing proximal radioulnar joint
Neck
Radial tuberosity- Bony projection for attachment of biceps brachii
Radius distal
2 facets
Articulate with scaphoid and lunate
medial surface= ulnar notch, articulates with head of ulna
