Notes: please adhere to the guidelines explained in histology 101, which can be found under the laboratory tab on our owl site. Marks may be deducted if you do not read and follow these instructions. The intercellular bridges are desmosomes which appear as two dark bands when visualized with electron microscopy: what preparation artefact in h&e sections makes these intercellular bridges more visible? (0. 5 mark) Dehydration: compare and contrast types of secretion and complete the following chart. (3 marks) Briefly describe the method of secretion (i. e. : how the secretory cell releases its product) Secrete sebum into hair follicle through rupture of the cell s plasma membrane. Secrete contents directly into the hair through a duct. Contractile properties of surrounding myoepithelial cells squeeze fluid out of the acinus lumen and onto the surface of the skin: which layer of the epidermis is only found in thick skin?
