the largest or principal portion of the bone

the enlarge and often rounded end of a bone wich articulates with another bone

the constricted part fo a bone lying between the head and the body

a pronunced bend in a bone

a small smooth articular suface wich may be flat, concave, or convex

a smooth and rounded knob which articulates with another bone

a protuberance located above a condyle

a prominent but narrow ridge

prominent protuberance on the surface of a bone

a small rounded protuberance

a moderate protuberance

a very large protuberance on a femur

a shallow, wide, or elongated depression on the surface of a bone

a depression on the edge of a bone

a tunel which penetrates a bone

a large opening that gives way to a canal

an often rounded hole which pierces a bone

forms the roof of the skull and encases the top and lateral sides of the brain

forms the sides and base of the skull at the temples. it also forms the posterior portion of the cheekbone and articulates with the lower jaw. the auditory meatus(ear whole) pases through this bone

forms the forehead, including the brow ridge and upper surface of teh eye sockets

forms the roof of the nasal cavity and a portion of the base of the skull. (interior roof of the nose)

forms a portion of the base of the skull and is visible on the side of the cranium between the frontal and temporal bones, it is the location of the pituitary gland. (outside bone of the eye)

(back of skull)forms the base of the skull, and surrounds the foramen magnum( big whole in skull) whick is the opening for the spinal cord. it articulates with the atlas by tow occipital condyles

joins ot form the upper jaw, the anterior hard palate, and provieedes sockets for the upper teeth

forms the cheekbones and connects the maxillary bones to the frontal and temporal bones

forms part of the medial surface of each eye orbit. the orbits contain a groove that houses the lacrimal canal.(around the tear duck of the eye)

joins to form the base of the nose

located below the ethmoid bone on the lateral wall of each nasal cavity

forms the posterior part of the hard palate and a portion of the wall of the nasal cavity (roof of the mouth)

forms the lower jaw and contains scokest for the lower teeth

a small bone that forms the lower half of the nasal septum

vertebrate that forms the neck

provide a passage for the verebral arteries, and are found only on cervical vertebrae

is modified to articulat with the occipital condyle, which enalbes vertical up and down movement of the skull.

is also highly modified. it has a large medial process called the dens. articulates with the axis providing a pont of rotation which enables the horizontal turning of the skull

these are the verebrae of the chest to which ribs attach, and have long spinous processes which increase in height, inferiroly

these vertebrae form the lower back. the bodies are large and thick with long transvers processes, and shor, wide spinous processes

this is the result of the fusion of the five sacral vertebrae, and articulates with the coccyx and the pelvic gridle

this bone is the result of the fusion of between tree to five caudal , or tail, verebrae. is often called tail bone

this is commonly known as the breastbone. it is a falt narrow bone in te center of the upper chest, it articulates with the clavicles (collarbones) and the ribs

the costal cartilage attaches these ribs directly to the sternum. true ribs increase in length, inferiorly

the firs three pairs of false ribs are indirectly connected to the sternum by carilage attached to the costal cartliage of teh last true rib

are the last two pairs of false ribs. they donot connect to teh sternum. the false rivs become shorter, inveriorly
