1. Appendicular Skeleton

2. Appendicular Skeleton
Your appendicular skeleton includes all of the bones and joints that make up your appendages
This includes the shoulder girdles and pelvic girdles

3. Shoulder Girdle Your shoulder girdle consists of two bones Clavicle
Scapula

4. Scapula You have both a right and left scapula
It connects to two bones
Humerus
Clavicle
The scapula is sometimes called the “shoulder blade”

5. Clavicle Your clavicle is a small bone that connects to two bones
Sternum
Scapula
Your clavicle is sometimes called your “collar bone”
It is fragile. It only takes approximately 8 pounds of pressure to break.

6. Arm bones There are three bones that make up the bones of your arm
The humerus
The radius
The ulna

7. Humerus The humerus is the bone in your upper arm
It connects to three bones
The radius
The ulna
The scapula
You get the term “funny bone” from your humerus.

8. The Radius The radius is one of two bones of your lower arm
In anatomical position it is the bone on your “thumb side” of your arm
It gets its name because it has a circular head. Think about the radius of a circle when remembering which one is which.

9. The Ulna The ulna is the other bone in your lower arm
It is responsible for creating a majority of the joint of your elbow
It is on the pinky side of your arm in anatomical position.

10. The Hands Your hands are made up of 27 bones. You have 14 phalanges
You have 5 metacarpals
you have 8 carpal bones

11. Phalanges The phalanges make up the “finger bones” of your hand
Each finger has three phalanges except for the thumb which has only two.

12. Metacarpals
Your metacarpals are the bones of your hand that are long bones
You have one for each finger

13. Carpals You have carpal bones which make up the bones of your wrist
These 8 bones are bound by ligaments to restrict their movement

14. Pelvic Girdle Your legs attach to your thorax via the pelvic girdle
The pelvic girdle is made up of a left and right os coxae.

15. Os Coxae
Each os coxae is made up of three bones that are fused together in early development
The Ischium
The Ilium
The Pubis

16. The ischium
The ischium is the curved bone that forms the obturator foramen of the os coxae
It connects to both the ilium and pubis at the acetabulum

17. Ilium
The ilium is the large fan like bone that forms the “hip” portion of the os coxae
The width from one iliac crest to the other is called the false pelvis
The true pelvis is near the pelvic outlet

18. Pubis
The pubis is the anterior connection point of the left and right os coxae
It is the smallest of the 3 bones that make up the os coxae.

19. Male and Female differences in ossa Coxae
The female inlet is large and more circular
The female bones are usually lighter and thinner
The angle of the pubic arch is usually greater than 90 degrees

20. Legs Like your arms your legs are made up of three bones
One bone makes up the upper leg
Two bones make up the lower leg

21. Femur
The femur is the largest, heaviest, and strongest bone in the entire body
It has a large ball head the connects to the acetabulum of the ossa coxae

22. Fibula and Tibia You have two bones that make up the lower legs
The fibula -- skinner and on the lateral side in anatomical position
The tibia -- bigger and bulkier than the fibula. Located medially to the fibula.
Only the tibia connects to the femur and patella

23. Feet Your feet are composed of 26 bones
We break the feet up into 3 sections similar to our hands
Phalanges
Metatarsals
Tarsals

24. Phalanges Just like in your hands you have 14 phalanges
The consist of a proximal, medial, and distal phalange
Your “big toe” is constructed similarly to your thumb and does not have a medial phalange

25. Metatarsals Just like in your hands you have 5 metatarsals
Each one corresponds to a set of phalanges

26. Tarsals In your feet you have 7 tarsal bones
The two biggest are the talus and calcaneus
The talus connects your feet to your tibia and fibula
Your calcaneus is your “heel”

27. Patella Your “knee cap” is a singular bone
It connects to the femur, and tibia
