Histology analysis There were five steps involved in histological preparation. Step 1: Dissection and tissues collection The testis tissues were cut with a sharp scalpel into slices of not more than 2-3 mm thick and 10 mm long. The fixation process was commenced immediately after removal of the tissue sample. The specimen tube was filled with 20 ml of 10% formalin. The tissue was placed inside the specimen tube. Step 2: Dehydration Dehydration process begins when the fixed tissues was

Histology Purpose: What is the purpose of this exercise? The purpose of this exercise is to become more familiar with microscope and slides through observations of tissues. By looking at so many slides I am now much more comfortable at identifying some basic structures. The tissue slides were very important to my understanding of the tissue’s function. By looking at the dense regular tendon I can see how supportive it is because of all of the fibers present. It connected what I had read and

Introduction to Histology Introduction Histology is the microscopic study of cells and tissues of organisms. This study is important in the overall understanding of anatomy and physiology of organisms. It helps to understand the structures and functions of various tissues that make up bodily organs and systems (Wendy Wright‚ 2014). The cell theory states that a cell is the fundamental biological unit. All living organisms are composed of one or more cells‚ and every bodily activity that takes

Chem 1252‚ General Chemistry I Lab Johnson Acid-Base Titrations Introduction Titration is a convenient quantitative method for accurately determining unknown concentrations of solutions. A necessary requirement for its use is that a standard solution (a solution of known concentration) reacts chemically with the solution whose concentration is being determined. The standard solution is added to a solution of unknown concentration until all of the unknown solution has reacted. From the known quantity

HISTOLOGY PURPOSE: The purpose of this exercise is to be able to identify and correctly name the major tissue types in the body‚ as well as identifying the subcatergories of tissue types while observing them through the microscope and diagrams‚ and be able to explain the location and function of the tissue types in the body. There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used. EXERCISE 1: EPITHEILIAL TISSUE Epithelial Tissue Observations

HISTOLOGY: EPITHELIAL TISSUE o Human body composed of 4 basic types of tissue: epithelial‚ connective‚ nervous and muscular o Formed by cells and molecules of the extracellular matrix o Connective tissue: characterized by the abundance of extracellular fluid o Organs can be divided by parenchyma (composed of cells for main function of organ) and stroma ( supporting tissue) o Except in brain and spinal cord stroma made of connective tissue o Epithelial tissue: covering‚ lining protecting surfaces
