1. Long bones long and thin, designed to support body weight and en-
able movement. Ex. Humerus, tibia
2. Flat bones Flat and thin. Serve as protection (such as the cranium)
form the roof of the skull to protect the brain.
3. Short bones small and cube-shaped. enable movement. (the carpals
in the hand and tarsals in the foot)
4. Irregular bones varied in structure with ridges or irregular surfaces. Some
for movement and some for protection. (vertebrae and
pelvic bones)
5. Sesamoid bones small, flat, and round, reinforce tendons. Ex. patella
6. bone landmarks distinct marking, ridges, grooves, or holes, in the bone.
7. Foramen, canal, openings in bone to allow for nerves, blood supply, or a
fissure passageway
8. Sinus hollow chamber in bone, usually filled with air
9. Process, ramus elevations in bone
10. Trochanter, processes or projections for tendon or ligament attach-
tuberosity, ment
tubercle, crest,
line, spine
11. Head, neck, processes designed for articulation with adjacent bones
condyle,
trochlea, facet
12. Fossa, sulcus depressions in bone
13. Axial skeleton lies on the midline of the body and consists of the skull,
vertebral column, sternum, larymgeal skeleton, and tho-
racic (rib) cage.
14. Skull

formed by 22 bones: the cranium (8 bones) and facial
bones (14 bones).
15. Cranium protects the brains and is composed of eight bones fitted
tightly together in adults.
16. fontanelles "soft spots". Membranous regions that join bones in new-
borns that are not completely formed. Allow the bones
of the skull to compress during childbirth and expand
to accommodate a rapidly growing infant brain. Begin to
close around two months but may last up to two years.
17. Frontal bone One bone. Forms the forehead
18. Parietal bones two paired bones. Extend to the sides.
19. Occipital bone Curves to form the base of the skull.
20. temporal bone below the much larger parietal bones. Each have an
opening that leads to the middle ear.
21. Sphenoid bone Completes the sides of the skull and contributes to the
floors and walls of the eye sockets. Lies largely inside the
skull
22. Ethmoid bone Lies in front of the sphenoid. Is part of the orbital wall
and, in addition, is a component of the nasal septum. Lies
largely inside the skull.
23. Foramen mag- Large opening in the occipital bone through which the
num spinal cord passes to become the brain stem.
24. sinuses air spaces lined by mucous membrane. reduce the weight
of the skull and give a resonant sound to the voice.
25. mastoid sinuses drain into the middle ear
26. Mastoiditis a condition that can lead to deafness, is an inflammation
of the mastoid sinuses.
