Ch. 7 Skeletal System:

Draw and Label the parts of the
The Thoracic Cage
Pectoral Girdle
Upper Limb

2. Thoracic Cage Composed of: Ribs Sternum Thoracic vertebrae
Costal cartilages
Function:
Supports shoulder girdle
and upper limbs
Role in breathing

3. Ribs Usually 24 ribs True ribs (7 pairs) Join the sternum directly
False ribs (3 pairs)
Do not attach to sternum directly
Floating ribs (2 pair)
No attachment to sternum

4. Rib Structure Shaft Head – posterior end; articulates with vertebrae
Tubercle – articulates with vertebrae
Costal cartilage – hyaline cartilage

5. Sternum Aka breastbone Located anteriorly at the midline Manubrium
Body
Xiphoid process

6. Pectoral Girdle aka shoulder girdle Consists of: clavicles scapulae
Function:
supports upper limbs

7. Clavicles Aka collar bone Slender, rod like bones
Located at base of neck
Run horizontally between the sternum and the scapulae

8. Scapula Aka Shoulder blade Broad, triangular bones
Located on both sides of upper back

9. Upper Limb Consists of: Humerus Radius Ulna Carpals Metacarpals
Phalanges
Function:
Attach to muscles to move limb parts

10. Humerus Long bone Extends from scapula to the elbow
Moves upper limb at shoulder
head
greater tubercle
lesser tubercle
anatomical neck
surgical neck
deltoid tuberosity
capitulum
trochlea
coronoid fossa
olecranon fossa

11. Radius Located on the thumb side Shorter than ulna
Extends from elbow to wrist
Crosses over ulna when the hand is turned
Allows the radius to rotate

12. Ulna Aka elbow bone Longer than radius Overlaps the humerus
Allows your arm to bend at the elbow

13. Wrist and Hand Made up of wrist, palm, and fingers Wrist Carpal bones
Two rows, with 4 bones each
Palm
Metacarpals
Ends are your knuckles
Thumb side most freely movable
Fingers
Phalanges

The Pelvic Girdle
Lower Limb
Ch. 7 Skeletal System:
Major Bones of the Body
2.1 Atoms, Ions, and Molecules
On Page 88 draw and Label the parts of the
The Pelvic Girdle
Lower Limb

18. Pelvic Girdle Consists of: Coxae (2) Function: supports trunk of body
Provides attachments for lower limbs
Protects bladder, reproductive organs, part of lg. intestine
body’s weight is transmitted through the pelvic girdle to the lower limbs then onto the ground

19. Coxae Aka hip bone Ilium Largest part Forms “hip” Ischium
Supports the weight of the body while sitting
pubis
anterior portion
Two pubic bones come together at the midline
Form pubic arch

20. Pubic arch

21. Greater and Lesser Pelves
Greater Pelvis
lumbar vertebrae posteriorly
iliac bones laterally
abdominal wall anteriorly
Lesser Pelvis
sacrum and coccyx posteriorly
lower ilium, ischium, and pubis bones laterally and anteriorly

22. Male and Female Pelves Female iliac bones more flared broader hips
pubic arch angle greater
more distance between ischial spines and ischial tuberosities
sacral curvature shorter and flatter
lighter bones

23. Lower Limb Consists of: Femur Patella Tibia Fibula Tarsals Metatarsals
Phalanges

24. Femur aka thigh bone Longest bone of body
Extends from the hip to the knee

25. Patella aka kneecap Located on anterior surface of knee
Allows lower limb movements

26. Tibia Aka shin bone Larger of the two leg bones Located on medial side
Enters into knee joint

27. Fibula
Lateral to tibia
Long, slender
Does not bear any body weight

28. Ankle and Foot Made up of ankle, the instep, and the toes Ankle
Tarsals
Calcaneus aka heel bone
Supports body weight
Instep
Metatarsals
Form ball of foot and arch
Provide stable, springy base for body
Toes
Phalanges
Shorter than fingers
