Intro to Anatomical Terms Flashcards
sagittal plane
vertical plane that divides body into left and right parts
midsagittal plane
vertical plane that divides body into left and right parts, through the midline
parasagittal plane
vertical plane that divides body into left and right parts, NOT through the midline (asymmetric)
frontal plane
coronal plane
vertical plane that divides boy into front and back parts
transverse plane
horizontal plane
divides body into upper and lower parts
medial vs. lateral
closer to midline (midsagittal plane)
farther from midline (midsagittal plane)
anterior (ventral) vs. posterior (dorsal)
closer to front of body
(in reference to frontal plane)
closer to back of body
(in reference to frontal plane)
superior (cranial) vs. inferior (caudal)
closer to head
(in reference to transverse plane)
closer to feet
(in reference to transverse plane)
proximal vs. distal
closer to root of the structure (ie. arm is proximal to forearm)
farther from root of the structure (ie. ankle is distal to knee)
superficial vs. deep (profundus)
closer to surface of body
away from body surface
ipsilateral vs. contralateral
on same side of body
on opposite sides of body
internal vs. external
inside body cavity
outside body cavity
palm vs. dorsum
anterior aspect of hand
posterior aspect of hand
sole (plantar) vs. dorsum
inferior aspect of foot (ie. thick skin of sole of foot)
posterior aspect of foot
flexion vs. extension
(occurs in sagittal planes)
bending or decreasing angle between parts of the body
straightening or increasing angle between parts of the body
abduction vs. adduction
(occurs in frontal planes)
moving away from midline or axis of body parts
moving toward midline or axis of body parts
What is the axis of the hand?
passes through 3rd finger and metacarpal bone
What is the axis of the foot?
passes through 2nd toe and metatarsal bone
medial rotation vs. lateral rotation
(occurs in transverse planes)
turning body part around its long axis toward midline
turning body part around its long axis away from midline
circumduction
circular movement of body parts combining flexion, extension, abduction, adduction, and/or rotations
supination vs. pronation
rotation of forearm so that palm of hand faces forward
rotation of forearm so that palm of hand faces backward
eversion vs. inversion
turning sole of foot outward
turning sole of foot inward
plantar flexion vs. dorsi flexion
moving foot away from shin (flexion of ankle joint)
moving foot toward shin (extension of ankle joint)
elevation vs. depression
upward movement of body part
downward movement of body part
protraction vs. retraction
forward movement of body part
backward movement of body part
opposition
movement of thumb to touch the other fingers’ tip
What are the body organization levels?
(chemical level)
atoms → molecules →
(cellular level) organelle → smooth muscle cell →
(tissue level) smooth muscle tissue →
(organ level) organ →
(organ system level) →
(organismal level)
What is the integumentary system?
forms external body covering, and protects deeper tissues from injury
What does the integumentary system synthesize?
vitamin D
