Anatomical Terms of Position/Movement Flashcards
Flexion
Movement generally in the sagittal plane that decreases the joint angle and brings two bones closer together
Example -
Crunch
Extension
Opposite of flexion, a movement increasing the angle or the distance between two bones or body parts
If extension exceeds 180 it is referred to as hypertension
Median Plane/sagittal plane
Centrally divides the body into symmetrical right and left halves
Flexion and extension such as the knee
Frontal/coronal plane
“Crown” centrally divides the body into symmetrical front and back halves (anterior and posterior)
Movement in this plane is adduction and abduction
Transverse/horizontal plane
Divides the body into symmetrical upper and lower halves (superior and inferior parts)
Movement in this plane is lateral rotation
Abduction “ABDuction”
Movement of the limb (in the frontal plane) away from the mid-line of the body
Also relates to spreading of the fingers and toes
Adduction - ADDuction
Movement of a limb towards the midline of the body
Rotation
Movement around a longitudinal axis
Usually a ball and socket joint, also present in the cervical spine
Circumduction
Combination of flexion, extension, abduction and adduction
Possible only at the shoulder and hip joints - ball and socket joints
Pronation
Occurs in the forearm as the palm of the hand moves palm down from an upward facing position
Also pronating in legs - more pressure on inside foot
Supination
Opposite of pronation
When the forearm is supinate, the ulna and radius are parallel
Also supinating In legs - more pressure on outside of foot
Prone
Face down
Supine
Face up - ie on your spine
Medial
Closer to the median plane
Lateral
Further from the median plane
Posterior
Facing toward or located at the back
Anterior
Facing toward or located at the front
Proximal
Closer to the trunk, or some major joint
Distal
Further from the trunk, or some major joint
Superior
Facing toward or located at the top (closer to the head)
Inferior
Facing toward or located at the bottom
Inversion
Turning the sole of the foot so it faces medially - it is a combination of adduction and plantar flexion
Eversion
Turning the foot so it faces laterally - it is a combination of abduction and dorsiflexion
Proprioception
Where you are in space - balance
Kinetic chain
Refers to the biomechanics of the body and to the end of the chain
Also refers to the body as a chain of alignment from head to toe
Open chain
If the end of a chain (hands/feet) are left free to move it is called open chain
Closed chain
When that same hand/foot is met with resistance (weight machine) it is a closed chain
