Movement and Anatomical Position Flashcards
Flexion
Bending the joint to reduce the angle of two or more bones.
Extension
The straightening of a joint to increase the angle of two or more bones
Abduction
The moving of a limb away from the median (ie: standing with your feet apart)
Adduction
The opposite of abduction. The movement of a limb towards the median (ie: standing with feet together)
Internal Rotation
The internal rotation of a limb moves it’s anterior surface medially.
External rotation
The opposite of internal rotation.
Circumduction
The circular motion combing flexion, extension, abduction and adduction.
Supination
Lateral rotation of the hand and forearm such that palms face up.
Pronation
The medial rotation of the arm and forearm such that palms face down.
Protraction
The moving in an anterior direction (forward).
Retraction
The moving in a posterior direction (backwards).
Dorsiflexion
The movement of the ankle that decreases the angle between the foot and lower leg
Plantar Flexion
The movement of the ankle that increases the angle between the foot and the lower leg.
Inversion
Occurs when the medial border of the foot is raised such that that sole of the foot is facing inwards.
Eversion
Occurs when the lateral border of the foot is raised such that the sole of the foot is facing outwards.
Elevation
The raising up to a more superior postion.
Depression
The pulling down to a more inferior position.
Opposition
When the thumb comes into contact with any of the other fingers.
Reposition
When the thumb returns to anatomical postion.
Anterior
Front surfaces of the body.
Posterior
Back surfaces of the body.
Superior
Upward surfaces.
Inferior
Downward surfaces.
Medial
Towards the midline.
Lateral
Away from the midline.
Proximal
Towards the point of attatchement.
Distal
Further away from the point of attatchement.
Superficial
On the surface of the body.
Deep
Under the surface of the body.
What is anatomical position ?
The body is upright in standing position, face/feet are pointing forwards, arms are at the sides, forearms are fully supinated (palms up).
Sagittal plane
A vertical plane that extends from the front of the body to the back, this acting as a median.
Frontal Plane
A vertical plane that extends from one side of the body to the other.
Transverse Plane
A horizontal plane that divides the body into upper and lower segments.
Anatomy
The structural aspect of living things.
Physiology
The functional aspect of living things.
________ determines function ?
Structure
