conoid tubercle / coracoid tuberosity

 

5

inferior view

Costal Tuberosity

- inferomedial side of clavicle

-  it's an "Impression for (the) Costoclavicular Ligament" and is sometimes known as such, rather than costal tuberosity

6

number 1

sternal extremity of clavicle

- articulates with manubrium

- pyramidal

7

marked by line w blue box

Subclavian Groove

- attachment for subclavius muscle on inferior side

8

17

trapezoid line

9

clavicle

- collar bone, 2 paired

- s-shaped

- articulates with scapula and sternum

know:

  • sternal extremity
  • acromial extremity

10

which clavicle is this? left or right

LEFT

on the superior view looking down, from sternum it arches straight out first and then bends back

11

which clavicle is this? left or right

RIGHT

this is a superior view of the right clavicle (since no conoid tubercle is visible)

- flatter acromial end is concave anteriorly, rounder sternal end is convex anteriorly

12

Capitate carpal

- articulates w/ metacarpal III (middle finger)

- largest carpal

13

Hamate Carpal

- articulates w/ metacarpals IV and V (ring and pinky finger)

- has "hook of hamate" or hamulus process

 

14

Lunate Carpal

- articulates directly w/ radius

15

D

pisiform carpal

Sits atop triquetrum, more easily seen in palmar view

16

Scaphoid carpal

- articulates directly w/ radius

- has tubercle

17

Trapezium carpal

- articulates w/ metacarpal I (thumb)

- has tubercle

18

F

Trapezoid Carpal

- articulates w/ metacarpal II (index finger)

19

Hamulus of Hamate carpal

- from 'hamus' meaning hook

26

humerus

- bone of brachial region of arm, articulates with scapula proximally and radius/ulna distally

- in addition to all markings know: anteromedial/lateral surfaces and medial/lateral borders
