1

axial skeleton

bones that lie around the longitudinal axis of the body

2

appendicular skeleton

bones of the upper and lower limbs plus the bones forming the girdle that connect the limbs to the axial skeleton

3

long bone

greater length than width; slightly curved for strength

4

short bone

somewhat cube shaped; consist of spongy bone tissue except at the surface where there is a thin layer of compact bone tissue; i.e. tarsals

5

flat bones

thin; composed of 2 parallel plates of compact bone enclosing a layer of spongy bone; provide big area for attachment

6

irregular bones

complex shapes; vary in amount of spongy and compact bone

7

sesamoid bones

shaped like a sesame seed; develop in tendons where there is considerable friction; i.e. palms and soles

8

sutural bone

small bones located in sutures between cranial bones

9

fissure

narrow slit between adjacent parts of bones through which blood vessels and nerves pass; i.e. superior orbital fissure of sphenoid bone

10

foramen

opening through which blood vessels, nerves or ligaments pass; i.e. optic foreman of sphenoid bone

11

fossa

shallow depression; i.e. coronoid fossa of humerus

12

sulcus

furrow along bone surface that accommodates blood vessel, nerve or tendon; inter tubercular sulcus of humerus

13

meatus

tubelike opening; external auditory meatus of temporal bone

14

condyle

large, round protuberance with a smooth articular surface at end of bone; lateral condyle of femur

15

facet

smooth, flat, slightly concave or convex articular surface; i.e. superior articular facet of vertebra

16

sulcus

furrow along bone surface that accommodates blood vessel, nerve or tendon; i.e. inter tubercular sulcus of humerus

17

meatus

tubelike opening; i.e. external auditor meatus of temporal bone

18

condyle

large, round, protuberance with a smooth articular surface at the end of bone; i.e. lateral condyle of femur

19

facet

smooth, flat, slightly concave or convex articular surface; i.e. superior articular facet of vertebra

20

head

usually rounded articular projection supported on neck (constricted portion) or bone; head of femur

21

crest

prominent ridge or elongated projection; iliac crest of hip bone

22

epicondyle

typically roughened projection above condyle; medial epicondyle of femur

23

line

long, narrow ridge or border (less prominent than crest); i.e. linea aspera of femur

24

spinous proces

sharp, slender projection; spinous process of vertebra

25

trochanter

very large projection; i.e. trochanter of femur

26

tubercle

variably sized rounded projection; greater tubercle of humerus

27

tuberosity

variably sized projection that has a rough, bumpy surface; ischial tuberosity of hip bone

28

skull

bony framework of the head

29

cranial bones

form the cranial cavity, which encloses and protects the brain

30

facial bones

form the face; two nasal bones, two maxillae, two zygomatic bones, the mandible, two lacrimal bones, two palatine bones, two inferior nasal conchae, and the vomer
