BIOL 3500 Lecture Notes - Lecture 7: Germ Layer, Nervous Tissue, Ground Substance
Document Summary
The study of tissues and how they are arranged into organs. The three layers (ectoderm, mesoderm, endoderm) of the late gastrulation, which develop into all parts of an animal. The germ layer that gives rise to the skin and nervous system. Develops into the linings (mucous membrane) of the digestive tract and much of the respiratory system. The germ layer that gives rise to the blood, bones and muscles. Embryonic connective tissue that arises from mesoderm and produces all types of connective tissues. Tissue is rubbed or spread across the slide rather than sliced. A body tissue that covers the interior and exterior surfaces of the body. Cells at the base (basal cells) of an epithelial layer are attached to this. Regulates the exchange of materials between the epithelium and the underlying tissues. Has only one layer of cells, with a scale like shape. Has only one layer of cells, with a cube like shape.
