Atlas
Forms the central axis of the body; consists of the skull, the vertebral column, the ribs, and the sternum or breastbone.
Axis
Very bottom portion of the spine; "tailbone"
Coccyx
Segments of cartilage that connect the sternum to the ribs and help to extend the ribs into a forward motion
Costal Cartilage
A vital role in supporting and protecting the delicate nervous tissue of the brain; found is the forehead region
Frontal
Largest, strongest, and lowest bone in the face; lower jaw or jawbone bone
Mandible
Forms the upper jaw and palate of the mouth
Maxilla
The "bridge" of the nose
Nasal
Situated at the back and lower part of the skull, is trapezoidal in shape and curved on itself
Occipital
When joined together, forms the sides and roof of the cranium
Parietal
Any of the lower five ribs on either side of the body, which are not directly attached to the sternum
Ribs - False
Any of the lower ribs that are not attached directly to the breastbone
Ribs - Floating
A rib that is attached directly to the breastbone
Ribs - True
At the bottom of the spine and lies between the fifth segment of the lumbar spine (L5) and the coccyx (tailbone)
Sacrum
Forms the center of the front of the chest
Sternum - Body
The upper portion of the sternum
Sternum - Manubrium
The breastbone
Sternum - Xyphoid Process
At the lower sides of the skull and directly underneath the temple
Temporal
Immediately below the skull
Vertebrae - Cervical

Vertebrae - Lumbar
Forms the prominent part of the cheek and the outer side of the eye socket
Zygomatic
The thigh bone
Femur
The kneecap
Patella
The heel bone
Calcaneus
The lowest and most anterior portion of the hip bones of the pelvis
Pelvis - Pubic Bone
Located between the ribcage and the shoulder blade, and it connects the arm to the body
Clavicle
Connects the hand to the forearm
Carpals
Any of the five bones in the hand
Metacarpals
The bones of the fingers and the toes
Phalanges (hand)
one of the two large bones of the forearm; extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna; exceeds it in length and size
Radius
Shoulder blade
Scapula
Most superior of the three bones that join to form the hipbone
Pelvis - Ilium
The lower and back part of the hip bone
Pelvis - Ischium
Any of the long bones of the fingers or toes; numbering 14 for each hand or foot
Phalanges
A group of five long bones in the foot
Metatarsals
A long bone in the arm or forelimb that runs from the shoulder to the elbow
Humerus
The lower front portion of the leg; shinbone
Tibia
Thin and lateral bone of the lower leg
Fibula
The ankle
Tarsals
One of the two long bones in the forearm; extends from the elbow to the wrist and runs parallel to the radius; exceeds in length and size
Ulna
Distal: end of each toe
Middle: smaller long bones that form the toes of the feet
Proximal: largest bones in the toe
Phlanges (foot)
Ear canal; a passage comprised of bone and skin leading to the eardrum
External Acoustic Meatus
A bump on the outside of the humerus where the deltoid muscle attaches
Deltoid Tuberosity (Humerus)
Pockets of space located above the orbit of each eye in the frontal bone
Frontal Sinus
The hole in the base of the skull through which the spinal cord passes
Foramen Magnum
Knob-like lateral projection at the proximal end of the femur
Greater Trochanter (Femur)
The curved superior border of the ilium; largest of the three bones that merge to form the hipbone
Iliac Crest
Prominence on the inner side of the ankle, formed by the lower end of the tibia
Medial Malleolus (Tibia)
Prominence on the outer side of the ankle, formed by the lower end of the fibula
Lateral Malleolus (Fibula)
An oval or circular opening on the anterior surface of the mandible
Mental Foramen (Mandible)
Process of the ulna that forms the outer bump of the elbow
Olecranon Process
Bony projection off the back of each vertebra
Spinous Process (Vertebra)
Projection on the lower end of the radius; may be felt on the outside of the wrist where it joins the hand
Styloid Process (Radius)
