Ch.07 KEY TERMS
what is anatomy
is the study of the form and structure of an organism.
what is a cell?
microscopic structures that carry on all the functions of life.
what is a cell membrane
The outer protective covering of the cell. It is also called the plasma membrane.
centrosome
Located in the cytoplasm and near the nucleus. It contains two centrioles.
what is chromatin
Located in the nucleus and made of deoxyribonucleic acid (DNA) and protein.
what is congenital
Acquired during development of the infant in the uterus and existing at or dating from birth.
what is connective tissue?
The supporting fabric of organs and other body parts.
what is cytoplasm
A semifluid inside the cell but outside the nucleus.
what is degenerative
caused by a deterioration of the function or structure of body tissues and organs either by normal body aging or lifestyle choices.
what is dehydration
A condition where there is not enough tissue fluid.
what is diagnosis
Identifying the disease or stating what it is.
what is edema
A condition where there is too much tissue fluid, or swelling of the tissues.
what is endoplasmic reticulum
A fine network of tubular structures located in the cytoplasm. This network allows for the transport of materials into and out of the nucleus, and also aids in the synthesis and storage of protein.
what is epithelial tissue?
Covers the surface of the body and is the main tissue in the skin. It forms the lining of the intestinal, respiratory, circulatory, and urinary tracts... [and] forms the body glands.
what is etiology
Refers to the cause of the disease.
what are genes
The structures that carry inherited characteristics.
what is a genome
The total mass of genetic instruction humans inherit from their parents.
what is golgi apparatus?

what is homeostasis
A constant state of natural balance within the body.
what is infectious
Caused by a pathogenic (germ-producing) organism such as a bacteria or virus.
what is inherited?
Transmitted from parents to child genetically.
what are lysosomes?
Oval or round bodies found throughout the cytoplasm. These structures contain digestive enzymes that digest and destroy old cells, bacteria, and foreign materials.
what is meiosis
This process uses two separate cell divisions to produce four new cells.
what is mitochondria
Rod-shaped organelles located throughout the cytoplasm. These are often called the "furnaces" or "powerhouses" of the cell.
mitosis
A form of asexual reproduction
