| The 14 bones of the toes, comprised of a proximal, middle, and distal bone for each toe and a proximal and distal bone for the two big toes. | Phalanges (toes) |
| The five bones of the foot that connect to the toes. | Metatarsals |

| The smaller bone of the lower leg. | Fibula |
| Also known as the shinbone, this is the larger and stronger of the two bones in the lower leg. | Tibia |
| This phone is also known as the kneecap. | Patella |
| Also known as the thighbone, this is the longest and strongest bone in the body. | Femur |
| The bony structure at the base of the spine, which has three parts: the ilium, the ischium, and the pubis. | Pelvis |
| The uppermost and largest part of the pelvis. | Ilium |
| The lower, rear part of the pelvis. | Ischium |
| The front part of the pelvis. | Pubis |
| This serves as the socket for the hip joint. | Acetabulum |
| Along with the maxilla bone, these two bones comprise the hard palate. | Palatine bones |
| Consisting of a body as well as a greater horn and a lesser horn and known by the alternate names of the lingual bone and the tongue bone, this horseshoe shaped bone is situated in the neck between the chin and the thyroid cartilage. | Hyoid bone |
| This facial bone, whose name is derived from the Latin word for a plowshare, is located in the midsagittal line and articulates with several other bones. It forms the inferior part of the nasal septum. | Vomer bone |
| Also known as the inferior turbinal or turbinate, this is comprised of three pairs of bones that extend horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone that curls upon itself like a scroll. | Inferior nasal conchae. |
| This hammer-shaped ossicle of the middle ear connects to a second middle ear bone and the eardrum. It transmits sound vibrations from the eardrum to the anvil. | Malleus |
| The name of this ossicle of the middle ear means “anvil”. This bone receives vibrations from the malleus and transmits them to the third ossicle of the middle ear. | Incus |
| The smallest and lightest bone in the human body, this bone’s name means “stirrup”. It is involved in conducting sound vibrations to to the inner ear. | Stapes |
