BIOL 105 - Lab 3
Histology : Basic
Tissue Types with
complete verified
solutions
What are the 4 types of tissues?
epithelial, connective, muscle, nervous
epithelial tissue
organized in sheets, joined together by tight junctions/ desmosomes
bound to underlying tissue by basement membrane
different shapes and layers of epithelial tissue
simple = one layer
stratified = more than one layer
squamous = squat, squished
cubodial = cube shaped, nucleus in center
columnar = elongated, nucleus shifted more towards one end
squamous epithelium
thin, flat, tile-like
simple - found on walls of capillaries or alveoli of lungs (must be thin for easy
transfer of gases in lungs)
stratified - surfaces subjected to abrasion (epidermis, lining of mouth, anus,
vagina)
