homeostasis
the proceses through which the body maintains a constant inernal environment.
hyperplasia
an increase in he number of cells in a tissue or organ.
hypertrophy
a general increase In the bulk of a body part or organ due to an increase in the size, but not the number, of cells in the tissues.
hypogastric region
located below the stomach.
hypoplasia
the underdevelopment of an organ or tissue, usually due to a deficiency in the number of cells.
iatrogenic illness
an unfavorable response due to prescribed medical treatment.

an illness caused by living pathogenic organisms such as bacteria and viruses.
inguinal
relating to the groin, refers to the entire lower area of the abdomen.
medial
the directon toward, or, nearer the midline.

also known as the midline, the sagittal plane that divides the body into equal left and right halves.

syndrome
a set of signs and symptoms that occur together as part of a specific disease process.
thoracic cavity
also known as the chest cavity or thorax; surrounds and protects the heart and lungs.
transverse plane
a horizontal plane that divides the body into superior (upper) and inferior (lower) portions.
umbilicus
commonly known as the belly button or navel, this pit in the center of the abdominal wall marks the point where the umbilical cord was attached before birth.
