pelvic bones femur tibia fibula patella tarsals metatarsals phalanges
Long bones 2 parts
diaphysis (shaft) and epiphyses (ends)
examples of long bones (4)
femur
ulna ‘phalanges
metacarpals
short bones i.e…
carpals
Irregular bones i.e…
vertebrae and some facial bones
sesamoid bones i.e….
patella
elongated and may have medullary cavity
diaphysis
epiphysis separated from diaphysis by…
growth plate (epiphyseal plate/line)
outer fibrous connective tissue covering bone
periosteum
Covering muscles, tendons and ligaments

cartilage is…by bone
REPLACED
definition of a joint:
where 2 bones come together
3 classifications of joints
cartilaginous joints
fibrous joints
synovial joints
cartilaginous joints aka
amphiartroses
fibrous joints aka
synarthroses
synovial joints aka
diarthroses
types of amphiarthrosis joints (2)
symphysis and synchondrosis
types of synarthrosis joints (3)
suture
gomphosis
syndesmosis
synovial joint capsule (2)
outer fibrous (innervated) inner synovial (vascularized)
Synovial joint close-packed and loose-packed positions (4)
position of joint surfaces
ligaments
vulnerability to injury
stability
synovial joint types: (6)
hinge pivot condyloid saddle ball and socket plane joints
tendons connect?
muscle to bone
ligaments connect?
bone to bone
densely packed bundles of collagen is a characteristic of?
tendons and ligaments
fibers and matrix of tendons and ligaments formed by?
fibroblasts
fibers and matrix of tendons and ligaments maintained b?
fibrocytes
each collagen fiber is surrounded by
endotendineum
fascicle surrounded by
peritendineum
tendon or ligament consist of? and surrounded by?
consists of a bundle of fascicles
surrounded by epitendineum
uniaxial joints move through
one plane around one axis
biaxial joints permit movement through
two planes around two axes
triaxial joints permit movement through
all 3 planes around all 3 axes
nonaxial (plane) joints characteristic?
consist of 2 relatively flat surfaces which slide over one another
fibrocartilage
pubic symphysis; intervertebral discs
symphysis
hyaline cartilage
epiphyseal plate, first sternocostal joint
synchondrosis
joints between bones of calvaria
suture
peg-in-a-socket
teeth in alveoli
gomphosis
interosseous membrane
syndesmosis
Flat bones I.e…
Ribs, sternum, scapulae, and certain skull bones
