Anatomy Lecture 1 Flashcards
Principle mass of a bone: with long bones, the shaft; with vertebrae, the anterior, weight-bearing portions between interventricular discs
Body
small, round, articular head (humerus)
capitulum
rounded, knuckle-like articular area, often occurring in pairs
condyle
ridge of bone
crest
eminence superior or adjacent to a condyle
epicondyle
smooth flat area, usually covered w cartilage where a bone articulates w another bone
facet
usually serve protective functions (cranial bones)
flat bones
passage through a bone
foramen
hollow or depressed area
fossa
elongated depresson or furrow
groove
large, round articular end
head
Varying shapes like bones of face
irregular bones
Linear elevation, sometimes called a ridge
line
Tubular bone
long bones
rounded process
malleolus
relatively narrow portion proximal to the head
neck
indentation at the edge of a bone
notch
extension or projection serving a particular purpose, having a characteristic shape, or extending in a particular direction
process
bulge or projection of bone
protuberance
bones that develop in certain tendons and are found where tendons cross the ends of long bones in the limbs; protect tendons from excessive wear and often change the angle of the tendons as they pass to their attachments
seasmoid bones
the diaphysis or body of a long bone
shaft
Cubiodial and are found only in the tarsus
short bones
thorn-like process
spine
large blunt elevation
trochanter
spool-like articular process or process that acts as a pulley
trochlea
small raised eminence
tubercle
large rounded elevation
tuberosity
divides body into left and right sections passing longitudinally through the midlines of the head, neck, and trunk
median plane
vertical planes passing through the body parallel to the median plane
sagittal plane
vertical planes passing through the body at right angles to median plane, dividing the body into the anterior and posterior parts
front (coronal) plane
horizontal planes passing through the body at right angles to the median and frontal plane dividing the body into superior and inferior parts
transverse plane
structure that is nearer the vertex (topmost part of cranium)
superior
structure nearer to the sole of the foot
inferior
