Flashcards in Bony Landmarks MD3 Deck (12):
1

Scapula

acromion, coracoid process, spine of scapula, scapular notch, supraspinous & infraspinous fossa, glenoid fossa, supraglenoid tubercle (origin for biceps brachii), infraglenoid tubercle (origin for long head of triceps)

2

Humerus

Humeral head, intertubercular/bicipital groove (latissimus dorsi inserts in the floor of the groove), Greater tubercle (inferior facet is insertion for teres minor, middle facet is insertion of infraspinatus, superior facet is insertion of supraspinatus), Lesser tubercle (insertion of subscapularis), surgical neck (more often fractured), anatomical neck, spiral/radial groove (houses radial nerve & deep brachial artery), deltoid tuberosity (insertion of deltoids)

Humerus

medial & lateral epicondyles

capitulum- distal humerus, lateral, small articulation to head of radius

trochlea- distal humerus, medial, articulates w/ trochlear notch on ulna

olecranon fossa- distal humerus, posterior aspect, depression that accomodates olecranon of ulna during extension of elbow

4

Carpal Bones

Q image thumb

(Lateral to medial, proximal to distal)

scaphoid, lunate, triquetrum, pisiform (on top of triquetrum), trapezium (thumb), trapezoid, capitate, hamate (hook)

Some Lovers Try Positions That They Can't Handle

5

Radius

Q image thumb

shorter of two forearm bones, lateral side of elbow to thumb side of wrist

head articulates w/ capitulum of humerus & radial notch of ulna proximally

radial neck

upper 1/3: supinator, flexor digitorum superficialis (via anterior oblique line), flexor pollicis longus

middle 1/3: pronator teres

lower 1/3: pronator quadratus

radial/bicipital tuberosity: attachment of biceps tendon

articulates w/ ulna, scaphoid & lunate carpal bones distally

styloid process: insertion of brachioradialis,

6

Ulna

Q image thumb

larger of two forearm bones, medial (pinky side)

bigger proximally (radius bigger distally)

olecranon & coronoid process form trochlear notch for articulation w/ trochlea of humerus proximally

head of ulna articulates w/ ulnar notch on radius distally

ulna does not extend to wrist

Metacarpals

I-V

8

Phalanges

Q image thumb

proximal, middle, distal (except for thumb, which is just proximal & distal)

9

Interphalangeal joints

Q image thumb

proximal interphalangeal joint (PIP)

-b/w proximal & middle

distal interphalangeal joint (DIP)

-b/w middle & distal

*except thumb, which only has one IP joint

*also remember the carpometacarpal & metacarpophalangeal (knuckle) joints (CMC, MCP)

10

Tarsal Bones

Q image thumb

-Calcaneus (heel), Talus, Navicular, Cuboid, Lateral Cuneiform, Intermediate Cuneiform, Medial Cuneiform

 

-Many Intermediate Lovers Can't Navigate The Clitoris

(medial, intermediate, lateral cuneiforms, cuboid, navicular, talus, calcaneus)

-sustentaculum tali- medial side of calcaneus, harry runs underneath, attachment of spring ligament

11

Metatarsals & Phalanges

Q image thumb

2-5 have middle phalanges (not great toe), all have proximal & distal phalanges

12

Sesamoid bone on great toe

Q image thumb

ball of foot,

acts as a lever for flexor hallucis longus,

no ligamentous attachment (tucked under FHL),

fx d/t repetitive force (soccer)
