Planes and Sections Flashcards
toward the head, or the upper part of a structure
superior
away from the head, or the lower part of a structure
inferior
nearer to or at the front of the body
anterior
nearer to or at the back of the body
posterior
nearer to the midline
medial
farther from the midline
medial
farther from the midline
lateral
between two structures
intermediate
on the same side of the body as another structure
ipsilateral
on the opposite side of the body from another structure
contralateral
nearer to the attachment of a limb to the trunk; nearer to the origination of a structure
proximal
farther from the attachment of a limb to the trunk; farther from the origination of a structure
distal
toward or on the surface of the body
superficial (external)
away from the surface of the body
deep (internal)
planes and sections
imaginary flat surfaces that pass through the body parts
sagittal plane
a vertical plane that divides the body into right and left sides
midsaittal plane
divides the body into equal right and left sides
parasagittal plane
divides body into unequal right and left sides
frontal plane
divides the body or an organ into anterior (front) and posterior (back) portions
transverse plane
divides the body or an organ into superior (upper) and inferior (lower) portions
oblique plane
passes through the body or an organ at an angle

G1 phase
cell metabolically active;
duplicates organelles and cytosolic components;
centrosome replication begins
S phase
DNA replicated
G2 phase
cell growth continues;
enzymes and other proteins are synthesized; centrosome replication completed
