Chapter 1: Intro Flashcards
immovable type joint, no cavity
synarthrosis
What classification of joint are the cranial sutures and sternocostal joints?
synarthrosis
slightly movable joints between two bones
amphiarthrosis
joint with opposed surfaces of bone are connected through fibrocartilage
symphysis
what class of joint would be symphysis pubis or intervertebral discs
symphysis
joint where fibrocartilage forms an interosseous ligament between bones
syndesmosis
what classification of joint would the inferior tibiofibular articulation or the infant skull
syndesmosis
freely moving joint lubricated with synovial fluid within a joint space, capsule surrounding the joint and supported by ligaments and muscles
diarthrosis
gliding joint where bones slide face to face with restricting ligaments
arthrodia
what classification of joint is the intercarpal and intertarsal joint
arthrodia
hinge joint allowing movement in one plane
ginglymus
what class of joint is the knee or elbow
ginglymus
joint where opposing bones fit the contour of another and increase the extent of the hinge movement to include other planes of motion
saddle joint
what class of joint would be the first carpometacarpal (thumb)
saddle joint
modified ball and socket joint where one bone is shaped like a spindle or ellipsoidal and not spherical
ellipsoid
what class of joint is the wrist?
ellipsoid
pivot joint resembling a pulley, allows movement in a partial ring
trochoid
what class of joint is the radioulnar joints
trochoid
ball and socket joint where spherical head fits into a cup-like pocket with free movement
enarthrosis
what class of joint is the hip or shoulder?
enarthrosis
What is the Hounsfield scale?
numbering scale used in CT imaging that represents the differing radiodensities and radiolucency to help distinguish structures
What are the values for bone, water, and air on the Hounsfield scale?
bone is +1000
water is 0
air is -1000
When viewing an axial section and the pt is supine, the patient’s right side should be on the _____ side of the image
left
the plane that divides the body into anterior/posterior portions
coronal or frontal
In MRI, which weight of imaging will have a bright/high signal from fat tissue?
T1
In a PET scan, the cellular consumption of _____ is measured and used to create diagnostic images.
glucose called FDG
Describe the process of ultrasound diagnostic imaging
high frequency soundwaves are projected into the body and are reflected off internal body structures and then received by the transducer to process/make an image
