Lecture 2: The Skeletal System Flashcards
Flexion
Bending
Joints get smaller
Decreasing angle
Extension
Straightening
Increasing Angle
Abduction
moving away
Adduction
moving towards
Rotation
Movement around the long axis
medial/ internal or lateral/external
Circumduction
Combination of movements (ball & socket joints): flexion extension adduction and abduction
Protraction
Moving the structure anteriorly/forward
Retraction
Moving the structure posteriorly/backward
Elevation
Raising the structure cephalad (superiorly)
Depression
Lowering the structure caudally (inferiorly)
Supination
The forearm is rotated laterally (palm up)
Pronation
The forearm is rotated medially (palm down)
Ulnar deviation
Adduction of the wrist
Radial deviation
Abduction of the wrist
Opposition
Thumb moves medially to meet the other fingers. Act of Abduction and Flexion
Reposition
Put the thumb back to a neutral position. Adduction and Extension
Eversion
Plantar surface of the foot moves laterally
Inversion
Plantar surface of the foot moves medially
Dorsiflexion
Bending the ankle towards the shin
Plantar flexion
Bending the ankle towards the posterior/back of the body
Superficial
describes depth of the structure in relation to the surface of the body.
intermediate
describes depth of the structure in relation to the surface of the body.
deep
describes depth of the structure in relation to the surface of the body.
Medial
describes the structure being closer to midline of the body
Lateral
describes the structure being further from midline
Anterior
Front facing
closer to front
Ventral
Front facing
closer to front
Posterior
Back of body
dorsal
back of body
palmar
front of hand
Dorsum
Back of …
Plantar
Sole of foot
