synarthrosis - immovable
amphiarthrosis - slightly movable
diarthrosis - freely movable - __100% correct answer as
Joints are classified based on function & structure. What are the 3
classifications based on their function & how movable are they?
sutures: only in the skull,
gomphosis: fibrous joint between teeth & jaw bones
synchondrosis: cartilaginous joint within epiphysis of bone that
binds the diaphysis to the epiphysis,
synostosis: bony fusion joint between two bones found in the
fusion of the 3 coxal bones - __100% correct answer as
With the immovable joint, synarthrosis, what are the 4 types &
where are they found?
syndesmosis: ligaments that connect 2 bones but limit their
motion ie between radius & ulna, tibia & fibula
,symphysis: bones are separated by a wedge or pad of cartilage ie
between the pubic bones of the two coxal bones - __100%
correct answer as With the slightly movable joint,
amphiarthrosis, what are the 2 types & where are they found?
synovial joints
typically found at the ends of long bones
ex: shoulder joint, elbow joint, hip joint, knee joint - __100%
correct answer as With the freely movable joint, diarthroses,
what is it also called? Where is it found & what are examples?
a joint capsule, presence of articular cartilages, joint cavity with
synovial fluid, a synovial membrane, accessory structures (such
as cartilage, ligaments, tendons, bursae), & sensory nerves &
blood vessels - __100% correct answer as What are the 6
basic characteristics that all synovial/diarthroses joints possess?
lubricates surfaces of articular cartilages & reduces friction.
Nourishes chondrocytes by entering & exiting articular cartilages.
Acts as shock absorber. - __100% correct answer as What
are the 3 functions of synovial fluid?
extracapsular ligaments found outside of joint capsule &
intracapsular found inside of joint capsule. - __100% correct
answer as There are accessory ligaments & capsular
ligaments. What are the 2 types of capsular ligaments & where
are they found?
bursae - __100% correct answer as synovial tendon
sheaths surround some tendons are called what?
,a highly movable joint is not very strong (ex: diarthrosis); a fairly
immovable joint is strong (ex: synarthrosis) - __100% correct
answer as How does strength vs. mobility effect the joints?
abduction - __100% correct answer as angular motion that
is movement away from the midline of the body
adduction - __100% correct answer as angular motion that
is movement toward the midline of the body
flexion - __100% correct answer as angular motion that
Decreases the angle between the bones & the joint
extension - __100% correct answer as angular motion that
increases the angle between the bones at a joint
circumduction - __100% correct answer as angular motion
that is circular
moving head in a "no" manner - __100% correct answer as
What is an example of left and right rotation?
lateral rotation - __100% correct answer as What type of
rotation is it when you rotate the arm outward at the shoulder?
medial rotation - __100% correct answer as What type of
rotation is it when you rotate the arm inward at the shoulder?
supination - __100% correct answer as What type of
rotation is it when you have the hand in anatomical position?
, pronation - __100% correct answer as What type rotation is
it when the hand is rotated so the palm faces posterior or even
downward?
1- eversion, 2-inversion - __100% correct answer as What
are the 2 special movements depicted here?
a- dorsiflexion, b- plantar flexion - __100% correct answer
as What are the 2 special movements depicted here?
lateral flexion - __100% correct answer as Side-bending left
or right. Can be head to shoulder too.
top: protraction, bottom: retraction - __100% correct answer
as Anterior / posterior movement along transverse plane
Ex. Mandible (stick chin out / pull chin back)
abduction (because the scapula is moving further out from the
midline) - __100% correct answer as Protraction of the
scapula is also known as what?
adduction (because the scapula is moving back towards the
midline) - __100% correct answer as Retraction of the
scapula is also known as what?
1st: opposition, 2nd: reposition - __100% correct answer as
moving thumb toward other fingers and then back
elevation/depression - __100% correct answer as up and
down movement like in opening & closing jaw or shrugging
shoulders
