Intro to Anatomy, bones, and anatomical terms Flashcards
Sagittal Plane
-Bisects the body in left and right halves
Coronal Plane
-Bisects the body from front to back halves
transverse plane
-bisects the body horizontally into superior and inferior halves
Flexion
-brings two bones closer together and decreases the angle between them
extension
-brings two bones farther apart and increases the angle between them.
abduction
pulls a structure away the midline
adduction
pulls a structure toward the midline
what typical movement occurs in the sagittal plane and rotates about what axis
- flexion and extension
- transverse axis
what typical movement occurs in the frontal/coronal plane and rotates about what axis
- abduction and adduction
- anterior-posterior axis
what typical movement occurs in the transverse plane and rotates about what axis
- rotation
- vertical (longitudinal) axis
Meatus
canal like passageway to the interior of the body
fissure
narrow slitlike opening that houses nerves and blood vessels
- tends to be on the skull
sinus
cavity within a bone filled with air and lined with mucous membrane
fossa
shallow baseline depression in a bone often serving as an articular surface site for muscle attachment or even to support the brain of the body
trochanter
very large, blunt, irregularly shaped process that allows for muscle/ligament attachment
*the only example on femur
tuberosity
roughened site for muscle or ligament attachment to bone
tubercle
small rounded projection or process for muscle/ligament attachment to bone
foramen
round or oval opening through a bone
Head
bony expansion (a joint surface (expansion)) carried on a narrow neck
articular surface
any skeletal formation (bone cartilige) that makes normal, direct contact with another skeletal structure
notch
indentation at the edge of a bone often where nerves/tendons/blood vessels travel across the bone
groove/sulcus
surface passageway on a bone for nerves, blood vessels and tendons
line
narrow ride of bone less prominent than crest and allows for ligament/muscle attachment
process
any bony promnance for ligament/muscle attachment
facet
smooth nearly flat articular surface
epicondyle
raised area on or above a condyle for muscle and ligament attachment
condyle
rounded articular projection; often articulates with corresponding fossa
spine
sharp, slender often pointed projection for muscle/ligament attachment
crest
-narrow ridge of bone; usually prominant
what is the white part of an XRAY
the white parts on an xray are what are most dense and the rays do not pass through
fluoroscopy
allows to see a patient real time so swallowing or ingesting something like barium to detect issues
how does an MRI work
the magnet alligns all the hydrogens in the water in the body and alligns them using radio waves
