what are the anterior bones called
what are the posterior bones called
what is a fixed/fibrous joint
do not move - coronal structure
what is a cartilaginous joint
slightly moveable
vertebrae
what are the 6 types of synovial joints
- hinge
- ball and socket
- pivot
- saddle
- gliding
- condyloid
example of a hinge joint
elbow
example of ball and socket joint
shoulder
example of pivot joint
atlas and axis
what is an example of a saddle joint
carpometacarpal joint
example of a gliding joint
tarsal/carpal joint
example of condyloid joint
wrist joint
articulating bones in joints
what is hyperextension
Increasing the angle beyond 180 degrees when extending
what is horizontal abduction
moving the arm away from the body at a 90 degree
what is horizontal adduction
moving the arm towards the body from a 90 degree position
what movements are possible at a ball and socket joint
shoulder and hip: flexion, extension, abduction, adduction, rotation
what movements are available at a hinge joint
knee and elbow: flexion, extension
ankle: dorsiflexion, plantar-flexion
planes and axis key terms
examples of movement at the sagittal plane and transverse axis
example of movements at a frontal plane and sagittal axis
examples of movements at the transverse plane and longitudinal axis
what are the anterior muscles
what are the posterior muscles
different muscles in the quadricep
different muscles in the hamstring
different muscles in the hip flexor
what is an antagonistic pair
two muscles working together to cause a movement (one contracts while the other relaxes)
what is the main agonist on a downward and upward phase of a squat
quadricep
what is an isometric contraction
where a muscle contracts but the length of the muscle does not change (crucifix)
what is an eccentric contraction
occurs when the muscle lengthens due a greater opposing force
