Chapter 3: Levels of Organization Flashcards
Abduction
Movement toward the side, away from the body
Adduction
movement toward the side, toward the body
Anterior
toward or near the front; ventral
Posterior
Toward or near the back; dorsal
Base
The lower or supporting part of any structure
Apex
the pointed tip of a conical structure
Bilateral
both sides
Unilateral
One side
Contralateral
The opposite side
Ipsilateral
the same side
Deep
further into the body
superficial
nearer to the surface of the body
eversion
movement of the ankle causing the bottom of the foot to face toward the side or laterally
inversion
movement or the ankle causing the bottom of the foot to face toward the midline or medially
flexion
movement toward the front or anterior (exception at the knee joint)
extension
movement toward the back or posterior (exception of the knee joint)
Horizontal adduction
movement of the arm toward the midline, or anterior, when at shoulder level
Horizontal abduction
movement of the arm away from midline, or posterior, when at shoulder level
Medial
toward the midline; nearer to the middle
lateral
away from the midline; toward the side
medial rotation
rotation movement of the shoulder or hip toward the midline; internal rotation
lateral rotation
rotation movement of the shoulder or hip away from the midline; external rotation
pronation
rotation movement of the forearm to palm down; palm facing posterior
TIP
prone = pronation = facing down
supination
rotation movement of the forearm to palm up; palm facing anterior
TIP
supine = supination = facing up
protraction
movement of the scapula away from the spinal column; scapular abduction
retraction
movement of the scapula toward the spinal column; scapular adduction
proximal
nearer to the axial body
distal
further from the axial body
radial deviation
movement of the wrist toward the radius or away from the body; wrist abduction
ulnar deviation
movement of the wrist toward the ulna or toward the body; wrist adduction
superior
toward or nearer the head; cranial
inferior
toward or nearer to the feet; caudal
supine
lying horizontally facing upward
prone
lying horizontally facing downward
ventral
front; anterior
dorsal
back, posterior

BODY CAVITIES
Dorsal Cavity
posterior or back of the body, including the cranial and vertebral cavities
BODY CAVITIES
Ventral Cavity
anterior or front of the body, including the thoracic and abdominopelvic cavity
BODY CAVITIES
Cranial
houses the brain
crani - skull
BODY CAVITIES
Vertebral
vetebr- vertebra or backbone
spinal column
BODY CAVITIES
Thoracic
pertaining to chest region
Contains the lungs, heart, great vessels, trachea, and thymus
BODY CAVITIES
abdominopelvic
abdomen and pelvic areas
imaginary line between abdominal and pelvic cavities
BODY CAVITIES
abdominal cavity
stomach, pancreas, liver, gallbladder, and small intestines
kidneys lie at back of abdomen in the retroperitoneal space
BODY CAVITIES
retroperitoneal space
kidneys, lateral to the spinal column, back of the abdominal cavity
BODY CAVITIES
pelvic cavity
sigmoid colon, rectum, bladder
in females: uterus, fallopian tubes, and ovaries
Anatomical Position
the patient is standing upright, with arms at the side and palms facing forward. The patient’s legs are straight, and the toes are pointing forward.
Supine Position
lying horizontally, facing upward
Prone Position
Lying horizontally facing downward
Appendicular
the portion of the body that includes the arms, or upper extremities, and the legs, or lower extremities
terms used, proximal and distal
Fundamental Position
anatomical position but with the palms turned inward with the thumbs facing forward
Medical terminology students generally study the human body at this level
organ and organ-system levels
chemistry courses at the atomic and molecular levels
some biology courses at the cellular level
When the body is in a horizontal direction or producing rotation of the body part, it is moving in which plane?
when motion occurs in a horizontal direction or produces rotation of the body part, it is moving in the transverse plane
