Carpals | Bones of the wrist. |
Phalanges | Finger and toe bones. |
Patella | The round bone anterior to the knee joint. |
Scapula | The flat, "floating" bone that aids in arm movement. |
Pelvis | The bone structure that attaches the lower appendicular skeleton to the axial skeleton. |
Metacarpals | The bones found between the carpals and the phalanges. |
Spine | Vertebrae connect together to create the: |
Mandible | The lower jaw bone. |
Metatarsals | The bones found between the tarsals and the phalanges. |
Maxilla | The upper bone in the jaw. |
Tibia | Shin bone. |
Synovial Joints | Hip, knee, elbow, shoulder, knuckles. |
Cartilaginous Joints | Vertebral column, pubic symphysis. |
Fibrous Joints | Sutures between cranial bones |
Flexion | When the angle between two bones gets smaller. |
Extension | When the angle between two bones gets bigger. |
Adduction | When a limb gets closer to the axis. |
Abduction | When a limb gets father from the axis. |
Sagittal | Divide the body into left and right halves. |
Frontal | Divides the body into front and back. |
Transverse | Divides the body into top and bottom. |
Distal | Farther down the limb. |

Step 1 in Bone Remodeling | Loading causes micro-fractures. |
Step 2 in Bone Remodeling | Osteoclasts clear away the old bone. |
Step 3 in Bone Remodeling | Osteoblasts build a layer of new bone. |
