two Types of bone tissue
Spongey Compact
6 Types of bones
Long, irregular, short, flat, sutural, sesamoid
Long bone description
cylindrical shaft with knobby ends
long bone examples
Femur, humerus
short bone description
small chunky solid bones
flat bone description
broad flat shape, thin bones
flat bone examples
scapula, ribs, temporal skull bones, parietal
irregular bone description
chunky, complex shapes
irregular bone examples
vertebra, sphenoid, ethmoid skull bones
sutural description
small irregular bones found along cranial sutures
sesamoid description
tendons pass over a joint typically flexor tendons formed after birth
sesamoid examples
patella, pisiform
5 surface markings (depressions and openings)
fissure, foreman, fossa, sulcus, meatus
fissure description
deep furrow or cleft
foramen description
perforation through a bone or membrane
fossa description
depression, usually longitudinal
sulcus description
long narrow groove not as deep as a fissure
meatus description
external opening of a canal
fissure example
superior and inferior orbital fissures in the boney eye socket
foramen example
vertebral foreman for the spinal cord
fossa example
olecranon fossa of the distal humerus
sulcus example
bicipital sulcus of the humerus
meatus example
external auditory meatus
3 processes forming joints
condyle, facet, head
condyle description
rounded articular surface at extremity of bone
facet description
small smooth area on bone
head description
rounded extremity of bone
7 processes attaching tissue
crest, epicondyle, line, spinous process, trochanter, tubercle, tuberosity
crest description
bony ridge
epicondyle description
projection from long bone near the articular extremity
line description
long narrow mark or strip distinguished from adjacent tissue color
spinous process description
dorsal projection from center of vertebral arch
trochanter description
bony prominence at proximal femur
tubercle description
nodule not pathogenic
tuberosity description
large tubercle or rounded elevation from surface of bone
