|
Linea nigra The darkening of the linea alba, the hard-to-see white line that runs downthe center of the abdomen to the top of the pubic bone, during pregnancy. Pigmentation changes usually fade after delivery.
RELATED TERMS--------------------------------------
Abdomen
The area between the chest and the hips. Contains the stomach, small intestine, large intestine, liver, gallbladder, pancreas, and spleen.
Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.
Delivery
See drug delivery.
SIMILAR TERMS--------------------------------------
Linespread
The distribution of how the image of a very thin line is blurred on the retina (due to diffraction). Depends on pupil size.
PREVIOUS AND NEXT TERMS--------------------------------------
