Cytogenic
Producing cells
Cytoid
Resembling a cell
Cytology
Study of cells
Cytoplasm
Cell substance
Dysplasia

Epithelial
Pertaining to epitheluim
Erythrocyte
Red blood cell
Erythrocytosis
Increase in the number of RBCs
Histology
Study of tissue
Hyperplasia
Excessive development (number of cells)
Hypoplasia
Incomplete development (of an organ or tissue)
Karyocyte
Cell with a nucleus
Karyoplasm
Substance with a nucleus
Leukocyte
White blood cell
Leukocytosis
Increase in the number of white blood cells
Lipoid
Resembling fat
Myopathy
Disease of the muscle
Organomegaly
Enlargement of an organ
Somatic
Pertaining to the body
Systemic
pertaining to a body system, or body as a whole
Visceral
Pertaining to the internal organs
Cell
Basic unit of all life
Tissue
Group of similar cells that perform a specific function
Organ
Two or more kinds of tissues that together perform special body functions
System
A group of organs that work together to perform complex body functions
Cell membrane
Boundary of a cell
Cytoplasm
Gel-like fluid inside the cell
Nucleus
Central structure containing chromosomes
Types of Tissues
- Muscle, 2. Nervous, 3. Connective, 4. Epithelial
Muscle Tissue
Composed of cells that have a special ability to contract, usually producing movement
Nervous Tissue
Conducts impulses to and from the brain
Connective Tissue
Connects, supports, penetrates, and encases various body structures
Epithelial Tissue
Found in the skin and lining of the blood vessels
Chromosomes
46 in human cells except for mature sex cells which have 23
Genes
Regions within the chromosomes (determine hereditary characteristics)
DNA
Deoxyribonucleic Acid: Each gene is composed of DNA, a genetic material that regulates the activities of the cell
Integumentary System
Composed of the skin, nails, and glands. Forms a protective covering for the body, regulates body temp, and helps manufacture vit. D
Respiratory System
Composed of nose, pharynx, larynx, trachea, bronchial tubes, and lungs. Performs respiration which provides for the exchange of O2 and CO2 within the body
Urinary System
Composed of kidneys, ureters, bladder, and urethra. Removes waste material (urine) from the body, regulates fluid volume, and maintains electrolyte concentration.
Reproductive System
Female: ovaries, uterine tubes, uterus, vagina, and mammary glands.
Male: testes, urethra, penis, prostate gland, and associated tubes. Responsible for heredity and reproduction
Cardiovascular System
Composed of the heart and blood vessels. Pumps and transports blood throughout the body
Lymphatic System
Composed of a network of vessels, ducts, nodes, and organs. Provides for defense against infection and drainage of extracellular fluid
Digestive System
Composed of GI tract: mouth, esophagus, stomach, large and small intestine plus accessory organs, liver, gallbladder, and pancreas. Prepares food for use by the body cells and eliminates waste.
Musculoskeletal System
Composed of muscle, bones, and joints. Provides movement and framework for the body, protects vital organs such as the brain, stores calcium, and produces RBCs.
Nervous System
Composed of the brain, spinal cord, and nerves. Regulates body activities by sending and receiving messages
Endocrine System
Composed of glands that secrete hormones. Hormones regulate many body activities.
Body Cavities
- Cranial, 2. Spinal, 3. Thoracic/chest, 4. Abdominal, 5. Pelvic
