1 On Page 84 draw and Label the parts of the
Sponge: Set up Cornell Notes on Topic: Ch. 7 Skeletal System: Major Bones of the Body Essential Question: On Page 84 draw and Label the parts of the The Thoracic Cage Pectoral Girdle Upper Limb Ch. 7 Skeletal System: Major Bones of the Body 2.1 Atoms, Ions, and Molecules 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

14 Thoracic Cage True Ribs Sternum False Ribs

15 Pectoral Girdle

16 Humerus Upper Limb Radius Ulna Carpals Metacarpals Phalanges

Sponge: Set up Cornell Notes on Topic: Ch. 7 Skeletal System: Major Bones of the Body Essential Question: On Page 88 draw and Label the parts of the 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

29 Ankle and Foot

30 Pelvic Girdle Pubic arch

31 Lower Limb Femur Patella Fibula Tibia Tarsals Metatarsals Phalanges
