21
Q

These vertebrae form the lower back. The bodies are large and thick, with long transverse processes, and short, wide spinous processes.

A

Lumbar vertebrae

22
Q

This bone is the result of the fusion of the five sacral vertebrae. It articulates L5, the coccyx and the pelvic girdle.

A

Sacrum

23
Q

This bone is the result of the fusion between three to five caudal, or tail vertebrae. It is often called the tail bone

A

Coccyx

24
Q

This is commonly known as the breastbone. It is a flat narrow bone in the center of the upper chest. It articulates with the clavicles (collarbones) and the ribs.

A

Sternum

25
Q

Parts of the sternum

A

Manubrium
Body
Xiphoid process

26
Q

The costal cartilage attaches to these ribs directly to the sternum, and they increase in length, inferiorly.

A

True ribs

27
Q

The first three pairs of these ribs are indirectly connected to the sternum by cartilage attached to the costal cartilage of the last true rib. They become shorter, inferiorly.

A

False ribs

28
Q

Last two pairs of false ribs

A

Floating ribs

29
Q

These are the collar bones. They are long bones with a double-curve and function to increase the rigidity of the pectoral girdle

A

Clavicle

30
Q

These bones form the wrist and are arranged in two rows (4 bones in each row). They articulate with the ulna, radius, and metacarpals.

A

Carpals

31
Q

These are the bones of the palm of the hand. They articulate with the carpals and the phalanges.

A

Metacarpals

32
Q

These are the bones of the fingers. There are three bones in each finger, and two in each thumb.

A

Phalanges

33
Q

This bone forms the upper arm and, is the longest and thickest bone the arm. The proximal end articulates with the scapula and the distal end articulates with the ulna.

A

Humerus

34
Q

This is the bone of the forearm located on the same side as the thumb. It articulates with the humerus and ulna, proximally, and with the ulna and carpals distally.

A

Radius

35
Q

This is the longest bone in the forearm. It is located on the same side of the elbow as the little finger. It articulates with the humerus, radius, and the carpals.

A

Ulna

36
Q

Large triangular bones in the back. They articulate with the clavicle, humerus, and anchor muscles of the forelimbs.

A

Scapula

37
Q

These two bones form the pelvis. Each bone is formed by the fusion of the ilium, ischium, and the pubis on either side of the body. It joins the vertebral column at the sacroiliac joint.

A

Os coaxe

38
Q

Where does the right and left coaxe join anteriorly?

A

Pubic symphysis

39
Q

These are the largest bones in the pelvis. They form the upper and anterior portion of the hips.

A

Ilium

40
Q

These are the half ring shaped bones on the bottom of the coaxe. They are located in the buttocks, we sit on them.

A

Ischium

41
Q

The two pubic bones fuse to form the pubic region at the base of the hips

A

Pubis

42
Q

This is a socket that forms where the ilium, ischium, and pubic bones join. It is the socket portion of the ball-and-socket joint formed by conjunction with the femur.

A

Acetabulum

43
Q

These bones form the ankle. The bones move the ankle and function to support body weight.

A

Tarsals

44
Q

Largest and strongest of the tarsals, and it forms the heels.

A

Calcaneus

45
Q

These bones are similar to the metacarpals in the hands. They’re more massive because they support the body’s weight.

A

Metatarsals

46
Q

These bones are similar to the phalanges in the hands. They are much shorter and stouter because they provide stability, but cannot be used for manipulating objects.

A

Phalanges (foot)

47
Q

This is the bone of the thigh. It is the strongest, heaviest, and longest bone of the body. It articulates with the acetabulum proximally and with the head of the tibia distally.

A

Femur

48
Q

This bone is commonly called the kneecap. It is located inside a tendon of the quadriceps femoris muscle and does not articulate with any bone. Functionally, it increases leverage exceed by thigh muscles when extending the leg.

A

Patella

49
Q

This bone is commonly called the “shinbone” and is located on the inner side of the lower leg. It articulates proximally with the femur, and both proximally and distally with the fibula.

A

Tibia

50
Q

Forms the medial portion of the ankle

A

Medial malleolus

51
Q

This bone is located on the outer side of the lower leg. It is a slim bone and bears little weight. It functions to limit foot motion, with little side-to-side motion.

A

Fibula

52
Q

Forms the outer portion and strengthens the ankle joint

A

Lateral malleolus
