Anatomical Terminology Flashcards
Describe Anatomical Position
Person stands erect, feet together and facing forward, arms at sides, palms facing out, fingers facing down, head facing forward.
2 words that describe the FRONT of the body
Anterior or Ventral
2 words that describe the BACK of the body
Posterior or Dorsal
Sagittal Plane or Median Sagittal Plane
Creates left and right sides of the body
Coronal Plane
Creates front (anterior/ventral) and back (posterior/dorsal) sides of the body
Transverse Plane
A horizontal plane which creates top (superior) and bottom (inferior) regions of the body
Superior
references vertical position (higher than)
Inferior
references vertical position (lower than)
Medial
toward the midline of the midsagittal plane
Lateral
away from the midline of the midsagittal plane
Proximal
closer to the structure’s origin
Distal
farther away from the structure’s origin
Cranial
towards the head
Caudal
towards the tail
Superficial
towards the surface (used in reference to another structure)
Deep
away from the surface (used in reference to another structure
Rostral
toward the nose
Axial Skeleton consists of:
Skull, vertebrae, and ribs
Appendicular Skeleton consists of:
Pectoral girdle (clavicle and scapula), pelvic girdle (coxal bone), and the limbs
Parasagittal
Creates uneven left and right sides of the body
Flexion
bending a part of the body in such a way as to decrease the angle between the body parts
Example of Flexion
bending at the elbow so that the hand moves toward the shoulder
Extension
straightening a part of the body in such a way as to increase the angle between the body parts
Example of Extension
straightening at the elbow so that the hand moves away from the shoulder
Abduction
moving away from the median sagittal plane
Example of Abduction
bending at the shoulder so that the hand moves away from the body laterally (raising arms/hands laterally)
Adduction
moving toward the median sagittal plane
Example of Adduction
bending at the shoulder so that the hand moves toward the body laterally (lowering arms/hands laterally)
Pronation
medial rotation of the forearm and hand so that the palm goes from facing anteriorly to posteriorly
Supination
lateral rotation of the forarm and hand so that the palm goes from facing posteriorly to anteriorly
Elevation
raise body part superiorly
Example of Elevation
shrugging shoulders upward (superiorly) toward head
Depression
lower body part inferiorly
Example of Depression
lowering shoulders downward (inferiorly) toward trunk
Rotation (and name 2 types)
moving a part of the body around its long axis (medial/internal) or (lateral)
Medial Rotation
moving a body part around its long axis toward the midline or median sagittal plane
Example of Medial Rotation
When standing in anatomical position, the leg rotates so that the toes go from facing forward to facing toward the midline
Lateral Rotation
moving a body part around its long axis away from the midline or median sagittal plane
Example of Lateral Rotation
When standing in anatomical position, the leg rotates so that the toes go from facing forward to facing away from the midline
Circumduction
circular movement of the limbs or a portion of them, moving a limb in such a way that it creates a cone in space (the distal end creates a circle and the proximal end is the attachment and remains stationary
Example of circumduction
Arms circles. Shoulders (proximal end) remain stationary while hands (distal end) create a circle.
Dorsiflexion
Elevation of the of the dorsum of the foot at the ankle. Superior surface of the foot moves toward the shin.
Plantarflexion
Depression of the sole of the foot at the ankle. Depresses foot pointing toes.
Eversion
Turning the sole of the foot laterally (outward)
Inversion
Turning the sole of the foot medially (inward)
Protrusion/Protraction
Move the jaw anteriorly
Retrusion/Retraction
Move the jaw posteriorly
Opposition
Thumb and fingers come together to hold an object. Allows for grasping and manipulating objects.
Gliding
Translational movement. 2 flat surfaces glide or slip over each other
Prone
lying face down
Supine
Lying face up
Langer’s Lines
Collagen tension lines within the dermis. Fiber orientation lines.
Upper Limb consists of:
Arm and forearm. Arm is superior to forearm. Forearm is inferior or distal to the arm.
Arm consists of:
Region between the shoulder and elbow
Forearm consists of:
Region between the elbow and wrist
Lower Limb consists of:
Thigh and leg. Thigh is superior to leg. Leg is inferior or distal to the thigh.
Thigh consists of:
Region between hip and knee
Leg consists of:
Region between knee and ankle
