chapter 9 Flashcards
the joints of the skeletal system contribute to __________ by holding ______together in ways that allow for movement and flexibility
homeostasis
bones
what are 3 ways to name a point of contact between two bones, two bones and a cartilage, or between bone and teeth?
joint
articulation
arthrosis
scientific study of joints
arthrology
study of motion of a human body
kinesiology
joints are classified structurally based on their
anatomical characteristics
joints are classified functionally based on the type of
movement they permit
synovial cavity
presence or absence of space between the articulating bones
there are two criteria that the structural classification of joints is based on, what are they?
the presence or absence of synovial cavity;
type of connective tissue that binds the bone together
what are the 3 ways joints are structurally classified as?
fibrous joints
cartilaginous joints
synovial joints
no synovial cavity, and bones are held together by dense irregular connective tissue, thats rich in collagen fibers
fibrous joints
no synovial cavity and is held together by cartilage
cartilaginous joints
bones forming the joints has a synovial cavity and are united by dense irregular connective tissue of an articular capsule and often by accessory ligaments
synovial joints
what are the functional classification of joints?
synarthrosis
amphiarthrosis
diathrosis
synarthrosis
immovable joint
amphiarthrosis
slightly movable
diarthrosis
all diarthrosises are synovial joints; they have variety of shapes and permit several movements
what are three types of fibrous joints
sutures
syndesmosomes
interosseous membranes
fibrous joint composed of thin layer of dense irregular connective tissue, and occur only between bones in the skull
sutures
t/f sutures are movable or slightly movable
true
sutures replaced by bone in adults is
synostosis
metopic suture
when a suture that is obscure persists over age six
a fibrous joint in which there is a greater distance between articulating surfaces and more dense irreg. con. tissue than in a suture-permits limited movement
syndesmoses
what are two examples of a syndesmosis
distal tibiofibular joint
gomphosis
what is gomphosis
dentoalveolar joint
ex of gomphosis
the articulation between the roots of teeth and the socket
its has a substancial sheet of dense irreg. conn. tissue that binds neighboring long bones together-permits slight movement
interosseous membrane
where are two of the principle interosseous membranous joint
in the radius and the ulna; and
tibia and fibula
What are the 2 types of cartilaginous joint
Synchrondroses
Symphyses
One connecting martial is hyaline cartilage and what type of joint is it?
Synchondroses
It’s a cartilaginous joint
What’s and ex of synchondroses
Epiphyseal growth plate
Is Synchondroses synarthrosis/immovable joint?
Yes
