Exam 1 Flashcards
(37 cards)
Short Bones
no diaphysis, cube-shaped
ex: tarsals and carpals
Flat Bones
protectin and structure
ex: skull, ribs, sternum
Irregular Bones
do not fit in other categories
ex: vertebrae, pelvic bones, hyoid
Sesamoid Bones
embedded in tendon
found where tendons pass over angled structure or areas of high force
ex: patella, foot
Tuberosity
rounded prominence
Process
projection
Tuberercle
smaller rounded prominence
Condyle
large knob/protuberance at end of long bones
Epicondyles
rounded eminence of a condyle
Fossa
smooth hollow or depressed surface
Spine
long thin projection
Facet
small flat surface
Notch or Groove
a cut out or depression that allows passage
Foramen
hole or opening
Sinus
hollow space or cavity
Hinge Joint
uniaxial articulation
ex: elbow, knee
Ball and Socket Joint
bony rounded head fitting into a concave articular surface
ex: hip and shoulder joint
Plane (gliding/irregular) Joint
2 plane or flat bony surfaces which butt against each other
ex: vertebral facets in the spinal column, intercarpal joints, intertarsal joints
Condyloidal (knuckle joint)
biaxial ball and socket joint
ex: metacarpophalangeal or knuckles
Sellar (saddle) Joint
unique triaxial joint
ex: 1st carpometacarpal (this is the only example)
Trochoidal (pivot, screw) Joint
uniaxial articulation
ex: atlantoaxial joint (found in the neck)
Pennated
more fibers in a smaller area to generate more force
longer time to generate force
Parallel
fewer fibers so less force
quicker contraction time
First Class Lever
RAF
ex: neck
