Body Structure, Color, Oncology
cell
basic unit of all living things
cell membrane
forms the boundary of the cell
cytoplasm
gel-like fluid inside the cell
nucleus
largest structure inside the cell. contains chromosomes for cellular reproduction. control center & source of energy production
chromosomes
in the nucleus of the cell. 46 chromosomes in normal human cells / mature sex cells 23
genes
regions w/in the chromosome. each chromosome has thousands of genes that determine hereditary characteristics
DNA
(deoxyribonucleic acid) comprises each gene; genetic material that regulates the activities of the cell.
tissue
group of similar cells that perform a specific function
muscle tissue
composed of cells that have an ability to contract, usually producing movement
nervous tissue
cells found in nerves, spinal cord and brain. coordinates and controls body activities
connective tissue
connects, supports, penetrates and encases various body structures i.e. adipose (fat), osseous (bone) tissues and blood. fibrous tissue ligaments and tendons
epithelial tissue
major covering of the external surface of the body (skin); forms membranes that line body cavities and organs and is the major tissue in glands.
organ
two or more types of tissues that together perform special body functions.
viscera
large internal organs
system
group of organs that work together to perform complex body functions
cranial cavity
space inside the skull containing the brain
spinal cavity
space inside the spinal column containing spinal cord
thoracic cavity
space containing heart, aorta, lungs, esophagus, trachea, bronchi, and mediastinal area
abdominal cavity
space containing stomach, intestines, kidneys, adrenal glands, liver, gallbladder, pancreas, spleen and ureters
pelvic cavity
space containing urinary bladder, certain reproductive organs, parts of small and large intestine, and the anus
