1

Name the bones of the Pectoral Girdle, what articulates, and major feature

-Holds arms- greatest mobility in body

-Clavicle- collar bone
--articulates with manubrium of sternum and acromion of the scapula

-Scapula- shoulder blade (spine, acromion process, coracoid process, glenoid fossa, supraspinous fossa, intraspinous fossa_
--articulates with glenoid fossa with the head of the humerus

Acromion Process

-Scapula
-Rough projection from the spine, connects deltoid muscle
-connects with the clavical

Spine (of Scapula)

ridge located on the posterior side of bone

4

Coracoid Process

Scapula
rough bumpy, bicep muscle connection
anterior point of shoulder joint

5

Glenoid Fossa

Scapula-sockey
articulates with the humurous (shoulder dip)

6

Infraspinous Fossa

Scapula
Superior side of bone

7

Supraspinous Fossa

Superior side of bone

8

Subscapular fossa

Scapula
Anterior suface for muscle connection

9

Name the bones of the Pectoral Appendages (upper)

30 bones
1. Humurous- bone of the branchium
2. Radius- Lateral bone of four arm
3. Ulna-medial bone of four arm
4. Carpals- 8 bones arranged in 2 rows
5. metacarpals- 5 bones of the hand
6. Phalanges- 14 bones- proximal, medial, distal

10

Humerus

-Articulates with glenoid fossa of the scapula
-Head- smooth ball at proximal end
-Shaft- (aka) diaphysis (long part of bone)
-greater and lesser tubercles-proximal point of head, for muscle attachment
-Deltoid tuberosity-connects with deltoid muscle, on shaft
-trochlea- condyle- medial (pinky side) (SPOOL OF THREAD) inferior part of bone
-Capitulum-condyle-lateral surface-articulates with the head of the radius-distal end(elbow side)

11

Radius

-lateral bone of four arm (thumb side)
-head like a button cap, articulates with capitulum of humerus
-Styloid process-for stabilization

12

Ulna

-Medial bone of four arm (pinky side)
-Olecranon process-elbow-rough projection
-Semilunar=Trochlea notch- articulates with the trochler of humerus
-Styloid process- wrist nob, stabilizes carpal joint

13

Olecranon Process

Ulna- elbow superior process of semilunar arch (trochlear notch)

14

Trochlear notch

Ulna- articulates with the trochlea of humeros

15

Trochlea

Condyle- spool of thread-superior of humerus

16

Capitulum

Distal end towards elbow of the humerus
articulates with head of radius

17

Carpals

-8 bones in two rows of 4
-short bones
-Proximal row articulates with radius
-Distal row articulates with metacarpals

18

Metacarpals

-5 bones
-numbered lateral to medial (thumb to pinky)

19

Phalanges (Phalanx)

-bones of digits
-arranged in proximal, medial, distal
-14 phalanges per hand (thumb has only 2, others have 3)

20

Pollex

Thumb
Only has proximal and distal phalanges

21

Hallux

Big Toe

22

Digit

latin root
fingers and toes

23

how many phalanges in each hand/foot

14

24

list the three fetal bones that make up the acetabulum

Ilium-superior
Ischium-inferior, posterior
Pubis-inferior, anterior

25

Name our largest sesamoid bone

patella

26

Sesamoid bone

-bone formed in tendon

27

name the bones of the pelvic girdle

-Coxal bone
--ilium, ischium pubis fused
-sacroiliac joint- articulated with sacrum (unlike most joints b/c its rough)
-Iliac crest- most superior edge (hipbone)
-Ischial Tuberosity- anchor hamstring rough bumpy, sticks out
-Obturator foramen- sciatic nerve and arteries pass
-Pubis symphysis-made of fibrocartilage, joining two sides of pelvic bone.
-Acetabulum- where femur articulates, points laterally, all three parts contribute to this socket

28

Coxal Bone

formed by the joining fetal bones the Illium, Ischium, and Pubis bone

29

Illium

the most superior bone of the coxal bone

30

Ischium

inferior and posterior of the coxal bone

31

Pubis

Inferior and anterior of the coxal bone

32

Sacroiliac joint

Articulates with the sacrum, posterior. (rough, unlike other joints)

33

Iliac Crest

most superior edge (hip bone)

34

Ischial Tuberosity

Sticks out, rough and bumpy, anchors hamstring muscle inferior posterior enge

35

Obturator Foramen

big hole where arteries and sciatic nerve passes

36

Pubic symphysis

connection between R&L fibrocartilge

37

Acetabelum

The joint socket that articulates with femur, points laterally

38

Pelivc Appendage

-30 bones
-Femur, articulates with acetabulum with the coxal bone, distally articulates with the patella. The condyles articulate with the condyles of the tibia.
-Patella-sesmoid bone of the knee, articulates only with the femer
-Tibia- medial bone of the shin(the larger) articulated with the fibula both proximally and distally. Also articulates with the tarsals
-Fibula-lateral bone- articulates with the tibia and tarsals
-Tarsals-7- then articulate with metatarsals and phalanges. (including the hallux)
