Document Summary
Lecture 3 epithelia part 3 & connective tissue part 1. Carcinoma refers to a malignant tumor that arises from epithelia specifically. Malignant tumors are capable of metastasizing, travelling from the primary source tissues to other tissues of the body (ex. skin tumor travelling to the brain). They can grow uncontrollably as well but don"t spread. Carcinoma is malignant tumors that arise from epithelium. Malignant tumors can arise from other tissues as well; sarcoma (arising from muscles, blood vessels and bones), lymphoma (arises from lymphoid tissue) and leukemia (arises from white blood cells). Squamous cell carcinoma example there is a distinct line that separates the epithelium and connective tissue, but it seems to be blurred because the epithelium has now invaded the underlying tissue. Tissues are composed of cell and cell products. Connective tissues (everything from adipose, cartilage, tendons, bones) have fewer cells and the bulk of the tissue is cell product (acellular material; the cell matrix, stuff between the cells).
