Whereas the tissue in a relaxed or unstretched state will look like stratified cuboidal epithelium. Once the tissue is stretched the cells become flatter. How did this knowledge help you to identify the epithelium? Question #3 Structure name: Neuron of the spinal cord (Nervous tissue) Identify each label: A – Dendrite B –Nucleus in cell body C – Axon Direction of the nerve impulse: BAC Question #4 Name the tissue: Areolar Connective Tissue- one of most widely distributed connective tissues. List of all fibers present and function of each fiber Collagen – Very strong and resist pulling or stretching but they are not stiff which allows for the tissue’s flexibility. Elastic- smaller in diameter than collagen fibers that branch and join to create a fibrous network within the connective tissue. Reticular- consisting of collagen arranged in bundles with a coating of glycoprotein to provide support in the walls of the blood vessels to create a network around the cells in some tissues. List 5 types of cells present and function for each cell
SC121 Unit 4 Assignment Fibroblasts – large flat cells with branching processes. Usually present in general connective tissues, both are numerous. Macrophages- are phagocytes that develop form monocytes which are a type of white blood cells. Plasma Cells- located in many places in the body, most plasma cells do reside in the connective tissue. Adipocytes- are fat cells that store triglycerides. Found deep to the skin and around the organs such as kidneys or heart. Mast Cells - Involved in the inflammatory response, the bodys reaction to injury or infection and can also ingest, bind to, and kill bacteria. References Tortora, G. J., & Derrickson, B. (2017).
