Anatomical Terminology Flashcards
Sagittal plane
divides body vertically into right and left sides
Midsagittal/ Median Plane
vertical plane running directly down the middle of the body, divides into left and right
Parasagittal plane
divides body into unequal right and left sides
Frontal plane
divides body into anterior and posterior portion
Coronal plane
divides body into anterior and posterior portions
Transverse plane
divides the body horizontally into upper and lower portions
Cross-sectional plane
divides body into upper and lower portions
Cross sections
produced by transverse planes
Oblique planes
planes at any angle
Ventral
Toward belly side
Anterior
Dorsal
Toward back side
Posterior
Proximal
toward trunk
Distal
away from trunk
Superior
toward head
Inferior
away from head
serous membrane
lines ventral body
ventral body cavity contains
thoracic (lungs, trachea, heart, esophagus), abdominal (GI, spleen, kidney), pelvic (terminal GI tract, urinary, reproductive organs)
Serous membrane
lines ventral body cavities
3 components of serous membrane
visceral layer, parietal layer, serous cavity
Visceral layer
internal layer of serous membrane, covers external surface of organs
Parietal layer
external layer of serous membrane, covers internal wall of body cavity
serous cavity
between two layers of serous membrane, potential space, contains small amount of fluid
fenestration
small openings/windows
Foramen
short passage (doorway)
Canal/Meatus
passage through tube (hallway)
Fossa
concavity
Fissure
deep groove
Process
extention
Ramus
bifurcation, forked
related to spinal nerves
Crainal
Toward head
Rostral
Toward nose or mouth
Medial
toward mid-line
Lateral
away from mid-line
Ipsilateral
same side
Contralateral
opposite side
Deep
closer to inside, internal to another structure
Superficial
closer to outside, external to another structure
