Lab 1: Anatomical Terminology, General Osteology, and General Arthrology Flashcards
median sagittal
a vertical plane that passes through the midline of the body
- dividing it into equal left and right halves
sagittal
any vertical plane parallel to the median sagitall plane (= parasagittal plane)
coronal (frontal)
any vertical plane perpendicular to the sagittal
- divides body into front (anterior) and back (posterior) portions
transverse
(w/ reference to head, neck, and trunk) any horizontal plane
- divides body into upper (superior) and lower (inferior) portions
(w/ reference to limbs) any plane perpendicular to the long axis of the element
longitudinal
any plane that sections an element parallel to its long axis
planes of section
median sagittal sagittal coronal transverse longitudinal
terms of direction
superior (cranial) inferior (caudal) anterior (ventral) posterior (dorsal) medial lateral proximal distal
superior (cranial)
refers to 1 structure being above or closer to the head than another
inferior (caudal)
refers to one structure being below or closer to the feet or tail bone (coccyx) than another
anterior (ventral)
refers to one structure being in front of another
posterior (dorsal)
refers to one structure being behind another
medial
refers to one structure being closer to the median sagittal plane than another
lateral
refers to one structure being farther away from the median sagittal plane than another
proximal
refers to a structure of the upper limb or lower limb that is closer to the root (attachment) of the limb than another
distal
refers to a structure of the upper limb or lower limb that is farther away from the root (attachment) of the limb than another
palmar
the ventral surface (palm) of the hand or fingers
dorsal
the dorsal surface (back) of the hand or fingers
OR
the dorsal surface (back) of the foot or toes
plantar
the ventral surface (bottom or sole) of the foot or toes
specific terms: hands and feet
palmar
dorsal
plantar
specific terms: teeth
mesial distal lingual buccal occlusal
mesial
toward the anterior midline (ie. the midpoint btwn the 2 central incisor teeth) of the dental arch
distal
away from the anterior midline of the dental arch
lingual
toward the tongue (in reference to all teeth)
buccal
toward the cheek (in reference to the premolars and molars)
occlusal
the shewing surface that contracts the teeth in the other jaw (in reference to the premolars and molars)
superficial (external)
refers to on structure being closer to the outside (exterior) surface than another
more superficial = closer to external environment
deep (infernal)
refers to on structure being closer to the center (middle) of the head, trunk, or limbs than another
deeper = closer to the center
terms of movement
flexion / extension abduction / adduction rotation pronation / supination eversion / inversion plantarflexion / dorsiflexion circumduction opposition
flexion
movement that decreases the angle between two parts
- usually a movement to a more anterior location from anatomical position
extension
movement that increases the angle between two parts
- usually a movement to a more posterior location from anatomical location
abduction
movement of an appendage away from median sagittal plane
adduction
movement of an appendage toward median sagittal plane
rotation
movement that occurs around a central axis of a body part
pronation
rotary movement of the forearm so that the palm of the hand faces posteriorly (in extension) or inferiorly (in flexion)
