skeleton of a gorilla
lumbar vertebrae 
Bony parts of the back between the dorsal vertebrae and the sacrum.
thoracic vertebrae 
Bony parts supporting the ribs between the cervical and lumbar vertebrae.
cervical vertebrae 
Bony parts of the neck comprising the upper terminal end of the vertebral column.
scapula 
Large flat thin back bone articulating with the humerus.
floating rib 
Thin curved bone whose terminal end articulates with the vertebrae, while the other end remains free.
pelvis 
Bony girdle to which the legs are attached; the elongated shape of the pelvis prevents the gorilla from remaining upright for very long.
sacrum 
Bone resulting from the fusion of several vertebrae and located between the lumbar and caudal vertebrae; the pelvis articulates with it.
caudal vertebrae 
Bony parts fused together at the terminal end of the vertebral column and articulating with the sacrum.
femur 
Long bone of the hind limb articulating with the pelvis, the tibia and the fibula.
patella 
Small, slightly bulging triangular bone located on the front surface of the leg and articulating especially with the femur.
tibia 
Long bone forming the inner portion of the leg located between the femur and the tarsus (foot bone).
fibula 
Long bone forming the outer portion of the leg located between the femur and the tarsus (foot bone).
tarsus 
Portion of the leg formed of short bones between the tibia, the fibula and the metatarsus.
phalanges 
Bones articulating to form the skeleton of the digits.
phalanges 
Bones articulating to form the skeleton of the digits.
carpus 
Portion of the arm formed of short bones between the radius, the ulna and the metacarpus.
ulna 
Long bone forming the inner arm between the humerus and the carpus.
radius 
Long bone making up the outer section of the forearm; it is connected especially to the carpal bones to form the wrist joint.
humerus 
Long arm bone articulating with the scapula to form the shoulder, and with the radius and the ulna to form the elbow.
rib 
Thin curved bone articulating with the vertebral column and the sternum.
mandible 
Toothed bone forming the lower jaw.
maxilla 
Toothed bone comprising the upper jaw.
orbit 
Bony cavity of the upper portion of the head containing the eye.
skull 
Bony structure enclosing and protecting the brain.
