Lecture Notes Review: Tissue Types and Stem Cells

Flashcards covering key concepts about tissue types, their characteristics, locations, and stem cells, based on the provided lecture notes.

Extracellular matrix of connective tissue

Made up of fibers and ground substance.

Major tissue types

Muscle, epithelial, connective, and nervous tissue.

Tight junctions

Prevent fluids from seeping between epithelial cells.

Epithelial tissue locations

Glands, lining abdominal cavity, outer covering of internal organs (e.g., heart), outer layer of integument (skin), and lining of oral and nasal cavities.

Cartilage degeneration cause

Lack of exercise can cause cartilage at weight-bearing joints to degenerate.

Transitional epithelium location

Found in the urinary system.

Totipotent stem cell

A type of cell with the potential to develop into any type of human cell, including cells of the placenta and amniotic sac.

Areolar connective tissue

Widely distributed underneath epithelia such as the skin, acting as a reservoir of water and salts for surrounding tissues.
