Chpt 2.1 FA clavicle, scapula, humerus, ulna, and radius cards

Clavicle

• long bone ( runs medial - lateral)

• rounded sternal end ( articulates with sternum)

• Articulates with acromial process of scapula

Shoulder vs shoulder gridle?

Shoulder is referring to the glenoid Humeral

Shoulder gridle refers clavicle and scapula

Scapula ( landmarks)

-Superior and anterior angle ( top and bottom of scapula

-medial and lateral borders ( vertebra border sit close to spine) ( axillary border closer to armpit)

-spine ( posterior view)

-acromion process ( wing like project from spine)

-Coracoid process ( bird beck)

- Glenoid fossa ( where head of humerus goes)

-supraglenoid tubercle and infraglenoid tubercle ( bump on top of glenoid) ( bump on the bottom of glenoid)

-supraspinous and Infraspinous - separates rhe spine top to bottom

-subscapular fossa - scooped out area of anterior side of Scapula

Humerus

•long bone

• posterior / anterior ( p=olecranon in back) ( a= Coronoid fossa in front)

Head of humerus is ( medial side) / this helps identify which epicondyle is medial or lateral

humerus landmarks

-Head ( articulates with the glenoid)

-Neck (anatomical and surgical)

-Greater or lesser tubercles ( tuberosity) =bumps

-Bicipital groove ( anterior side)

-Deltoid tuberosity( bump side of humerus/ almost half way down the humerus

-Medial and lateral epicondyles - (m) same side as humerus / (L)opposite side of humerus

-spull and marvel aka trochlea and capitulum (t articulates with ulna trochlea notch) / (c meets radial head laterally)

Humerus landmark ( continued)

-Coronoid fossa ( medial hole of humerus) (Coronoid process of ulna goes into Coronoid fossa)

-Radial fossa ( lateral hole of humerus)( radial head goes into radial fossa when arm is bent)

-Olecranon fossa (posterior view) ( olecranon process of ulna is goes into fossa

Ulna

-Olecranon ( goes into olecranon fossa of humerus)

-trochlear notch (looks like a candy cane with a U)

-Coronoid process ( pointy front part)

- radial notch ( proximal end of bone, on lateral side where radial head fits

-Ulnar head - (distal end of bone)

-ulnar styloid process ( pointy projection on the end of ulna)

-

Radius

•long bone

•smaller proximally

•big distally

Radius ( landmarks)

-Radial head (spins against radial notch of ulna when supinating and pronating)

-Dorsal tubercle of the radius( a bump on distal/ dorsal surface of radius aka lister tubercle)

-Radial styloid process (pointed projection laterally to the dorsal tubercle)

-Ulnar notch of radius ( ln distal end of radius where it connect with ulna together)
