Anatomy And Physiology 5: Anterior Skeletal System

Front 1

Cranium

Back 1

Top of skull that protects the brain and sense organs

Front 2

Mandible

Back 2

The jaw, provides attachment for the chewing muscles

Front 3

Clavicle

Back 3

Traces a sinuous curve at the base of the neck; it acts as a strut supporting the shoulder

Front 4

Scapula

Back 4

Connects the arm to the trunk, and provides a secure but mobile anchor for the arm, allowing the shoulder to be retracted backward, protracted forward, and elevated

Front 5

Humerus

Back 5

Arm bone

Front 6

Ulna

Back 6

Medual forearm bone. Wide at its proximal end, where it articulates with the humerus at the elbow, this bone tapers to a pointed styloid process near the wrist

Front 7

Radius

Back 7

Forearm bone , it can radiate around the ulna to change the orientation of the hand

Front 8

Carpals

Back 8

8 small bones in the wrist

Front 9

Metacarples

Back 9

5 slender bones hidden at the base of the thumb and palm of the hand

Front 10

Phalanges

Back 10

Fourteen bones on each hand, two from the thumb and 3 (proximal, middle, distal) in each hand.

Front 11

Femur

Back 11

Largest bone in the body, leg bone

Front 12

Tibia

Back 12

Shinbone

Front 13

Fibula

Back 13

Attached to the tibia, it contributes to the ankle joint and provides a surface for muscle attachment

Front 14

Tarsals

Back 14

A group of 7 bones that form the ankle and heel bone (calcaneus)

Front 15

Metatarsals

Back 15

Five bones in the foot equivalent to the metacarpals in the hand

Front 16

Phalanges (foot)

Back 16

Fourteen bones that form the phalanges in the foot

Front 17

Patella

Back 17

Knee cap

Front 18

Sacrum

Back 18

Five fused vertebrae that provides a strong connection between the pelvis and spine

Front 19

Pelvis

Back 19

Big oddly shaped hip bone

Front 20

Ribs

Back 20

Twelve pairs of bones form the hips

Front 21

Costal cartilages

Back 21

Attach the upper ribs to the sternum, and the lower ribs to each other, and give the ribcage flexibility

Front 22

Sternum

Back 22

Breastbone containing 3 sections: Manubrium (superior sternum), Gladioulus (middle sternum), and Xyphoid Process (small bone that anchors the sternum)

Front 23

Manubrium

Back 23

Upper sternum bone

Front 24

Gladiolus

Back 24

Middle sternum bone

Front 25

Xiphoid Process

Back 25

Small anchor bone at the base of the sternum

Front 26

Vertebral Column

Back 26

Comprised of stacked vertebrae and forms a strong flexible backbone for the skeleton
