Exam One Flashcards
What are the different planes of motion?
Sagittal - left and right
Frontal - front and back
Transverse - top and bottom
Diagnol - combination of more than one
What are the different axes of rotation?
Frontal
Sagittal
Transverse
Describe the frontal plane
Perpendicular to sagittal plane
Runs medial to lateral
Flexion and extension
Describe the sagittal plane
Perpendicular to frontal plane
Runs anterior to posterior
Adduction and abduction
Describe the transverse plane
Perpendicular to transverse plane
Runs superior to inferior, longitudinal
Internal and external rotation
What is abduction ?
Movement away from the midline
What is adduction?
Movement toward the midline
What is circumduction?
Circular movement of a limb
What movements are specific to the ankle?
Eversion vs Inversion
Dorsal flexion vs plantar flexion
What movements are specific to the forearm?
Pronation and suppination
What movements are specific to the shoulder girdle?
Depression vs elevation
Protraction vs retraction
Upward vs downward rotation
What are the functions of the skeletal system?
Stores calcium Protects vital organs Support Movement Production of red blood cells
What is stress?
Force that will result in the deformation of bones
What is strain?
Force that results in compression and leads to distortion
What is wolffs law?
Bone size and shape are influenced by the direction and magnitude of force applied
What are the three classes of joints?
Fibrous - immovable - synarthrodial
Cartiligenous - slightly movable - amphiarthrodial
Synovial - freely movable - Diarthrodial
What are the six types of diarthrodial joints?
Enarthrodial - Ball and socket Ginglymus - Hinge Sellar - saddle Trochoidal - pivot Arthrodial - plane Condyloidal - ellipsoid
What is an example of a condyloidal joint?
Metacarpophalangeal joint
What is an example of a sellar joint?
Carpometacarpal Joint
What is an example of an arthrodial joint?
Intercarpal joint
What is an example of a trochodial joint?
proximal radioulnar joint
