Goblet Cells Secretes mucin which reacts with water to form mucus Mucus acts to lubricate the internal lining of the intestine Apocrine secretion
Mesothelium Simple squamous epithelium Lines all visceral organs as the visceral epithelium Lines body cavities as parietal epithelium
Stomach1. Tunica mucosa has inner layer of columnar cells and outer layer of loose connective tissue, the lamina propia chief cells and parietal cells are found in this layer2. Muscularis mucosa lies outer to the lamina propia has stratum circulare and stratum longitudinale3. Tela submucosa contains large blood and lymph vessels4. Tunica submuscularis thick and made up of circular layer of smooth muscles5. Subserosa narrow layer of connective tissues containing few longitudinal muscle strands6. Tunica serosa
IntestineTunica mucosa lines cavity of lumen made up of simple columnar epithelial cells and goblet cellsTunica submucosa muscular coat made up of two layers of muscles stratum circulare – thick inner circular layer stratum longitudinale – thin outer longitudinal layerTunica serosa outermost covering a thin layer of loose connective tissue covered with mesothelium
Muscle layers Muscularis mucosa --> moves the rugae, expels contents of gastric glands and allows for more exposure of epithelia with the chyme Tunical muscularis --> responsible for gut movement which churns the food
Kidney Adrenal gland --> endocrine system Veins vs. arteries --> thickness of walls
Spinal Cord Central Canal --> cerebrospinal fluid (CSF) Motor Neurons --> soma are spindle shaped, carries motor impulses which causes muscular contraction Multipolar neuron --> includes all motor neurons and internuerons, long axon, many dendrites
