Section 1

Question Answer
connection between 2 bonesjoint
function of jointmotion, bear weight, provide stability
as motion increases,stability decreases
immovable joints; most stablefibrous joints
2 cranial bones comme togethersuture
between teeth and bonecomphosis
support nonmovable joints between bonessyndesmosis
joins 2 bones by cartilagecartilaginous joints
between vertebrae/sternum and ribssynchondrosis
symphysis pubissymphysis joint
most imp to human movement; meausure thesesynovial joint
movement is linear; most stablenonaxial joint
movent around 1 axis and 1 planeuniaxial joint
motion occurs along 2 axes and 2 planesbiaxil joint
motion occurs in 3 axes and 3 planes; least stabletriaxial joint/multiaxial
articular surface of each bone dictate amt of motion/direction at each jointbone
joint support/protection; bone to boneligaments
surrounds joint and protectsarticular capsule
lines inside of jointsynovial membrane
thick fluid in membranesynovial fluid
synovial fluid functionsdecrease friction; move joints; shock absorbption; nutrition
dense fibrous connective tissue; withstands great pressure/tensioncartilage
covers end of bone; smooth surface; cant repair itselfhyaline
fills gap between 2 bones examplesshoulder joint and unal/carpal
shock absorber in weight bearing joint examplesknee, vertebrae, sternocalvicular
allows certain amt of motion examplessymphysis pubis and larynx
provide contraction force that moves joints to span; attatched to bones with tendonsmuscles
msucle to bonetendons
memorize

Section 2

Question Answer
may encase tendons at certain locations where tendons have frictionsheaths
found where muscle attatch to bone; muscle attatch where theres no boneaponeurosis
able to reduce friction between moving parts where excessive friction isnatural bursae
area becomes site of excessive frictionaquired friction
abnormal seperation of bone; limits motion and prevents activitydislocation
neurological isue; head of humeroussublaxion
ligament injury excessive motion occurs in absenseof no dislocation (wrist)sprain
inflimmation of joint caused by thickened articular soft tissueRA
degenerative; may or may not cause painRA
length of muscle when unstimulatedresting length
ability to contract; can shorten, stay same, or get bigcontractility
ability to shorten/get long when force is appliedextensibility
abiltiy to return to original shape AFTER shorting/lengtheningelasticity
ability to respond to multiple stimuliexcitability
more stable bone; closer to midlineorigin
more movable bone; distal to midlineinsertion
reverse muscle actionstabalize distally
name by locationtibialis anterior
name by actionextensor capi unlaris
name by shapetrapezius, rectus abdominus, serratus anterior
name by attatchmentsternocleidomastoid
name by fiber directionsexternal oblique
name by sizepectoralis major and minor
longer; greater ROMparallel muscle
shorter; strength; more stabalizingoblique muscle
muscles that are long and thin; fibers running length of musclestrap muscle
example of strap muslcessartorius, sternocleidomastoid
memorize

Section 3

Question Answer
example of fusiform musclebiceps, brachialis
shaped like spindlefusiform muscle
4 sided; flat broadrhomboidal muscle
example of rhomboidal musclegluteus maximus, rhoboids
flat; fan shpaed; fibers radiate from narrow attatchementtriangular muscle
ex of triangular musclepectoralis major
look like feather; short fibers attatched in diagnal along length of central tendonunipennate
common feather; fibers obliquely attatched to both sidesbipennate
many tendons with oblique fibers betweenmultipennate
muscle causes motion; prime moveragonist
muscle assist agonist; helpersynergist
muscle that performs oppost of agonistantagonist
steadily contracts to balancestabalizer
makes sure other muscles dont contract wrongneutralizer
no joint motion; staticisometric contraction
example of isometricpush against wall
muscle shortening remains same; equal motionisokinetic contraction
example of isokinetic muslcecycling
muscle tension remains same but length changesisotonic
see movement at joint; either elongates or shortensisotonic
force developed within muscletension
direct relationship betweenlengtha dn tension
muscle grows1.2x
muscle tone definitionresting
relieve active tension, the muscle isshortened
create passive tension, muscle islenghthend
