Tissues: Cells are organized into four basic types of tissues that perform specific functions 1. Epithelial tissues Epithelial tissue covers and protects body structures and lines organs, vessels, and cavities.
2. Connective tissue
Connective tissue supports and binds body structures. It contains fibers and other nonliving material between the cells. Examples are adipose (fat) tissue, cartilage, bone and blood Muscle tissue (root my/o) contracts to produce movement.
3. Muscle tissues
4. Nervous tissue
Nervous tissue (root neur/o) makes up the brain, spinal cord, and nerves. It coordinates and controls body responses by the transmission of electrical impulses.

BIOPSY: Biopsy is the removal and examination of a living tissue to determine a diagnosis. Biopsy comes from the Greek word “bios” meaning ‘life’, “opsis” meaning ‘vision’. Together they mean the visualization of living tissue. IN VIVO: "in the living body” IN VITRO: literally means “in glass” ,and refers to procedures and experiments done in labs.
IN SITU: means in its original place, used to refer to tumors that have not spread
Technicolor terms
• Leuk/o = white leukemia (overabundance of white blood cells) • melan/o = black melanoma (black tumor of the skin) • cyan/o = blue cyanosis (blueness may be due to cold or not enough oxygen in blood) • xanth/o = yellow xanthoma (yellow tumor)
Tumor talk
Adding - oma (a swelling) to organ and tissue word roots names tumors. Not all tumors are malignant (cancerous). Many are benign (not life-threatening).
• Aden/o = gland • adenoma • Lip/o = fat • lipoma • My/o = muscle • myoma • Lymph/o = lymph tissue • lymphoma • Carcin/o = malignant • carcinoma • Osteo/o = bone • osteoma
Thank you!
