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

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

Chapter 4 Study Guide Bio 169 • Individual body cells are specialized -Each type performs specific functions that help maintain homeostasis • Tissues are groups of cells that are similar in structure and perform a common function • Histology – study of tissues PRIMARY TISSUE TYPES: 1) Epithelial Tissue (or epithelium) is a sheet of cells that covers a body surface or lines a body cavity Forms boundaries Occurs in the body as covering and lining epithelium and glandular epithelium

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

WEEK 1 GEN Adverse reactions for drugs occur because: No drug has only one receptor it binds to. A drug that occupies and "turns on" a receptor is an: agonist Before marketing a new drug‚ the drug company asks the FDA to approve its choice of: trade name The time between when a drug response is observable and when there is no longer an observable drug effect is called the duration of action This term refers to how much of a drug must be given to see a desired response potency
