BIOL 2010 ANATOMY AND PHYSIOLOGY I Chapter 4: TISSUES AND MEMBRANES Outline of Notes I. Introduction. A. General: Cells are highly specialized and interdependent on one another. Groups of similar cells performing similar functions are called Tissues The study of tissues is called Histology. Organs are made of tissues. A detailed understanding of tissues will greatly help your understanding of organs and organ systems later in this course. Tissues are classified into 4 main types:

LAB REPORT 1 - LAB 7 CELL MEMBRANE FUNCTION Marisela Camacho Legarreta June 30‚ 2013 ACTIVITY 1 INTRODUCTION Be aware that all molecules have kinetic energy‚ which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration. METHODS Check the reaction of different

½Give an account of the structure and properties of Biological membranes. Include details of the modifications of membrane structure found in different specialised cells and organelles½ The Fluid Mosaic model was codified by Singer and Nicolson in 1972. It describes the structure and properties of the cell membrane very simply. Every membrane consists of a Phospholipid bilayer. This is simply two layers of phospholipid molecules that come together due to their unique properties. The heads of the

The cell wall maintains the integrity of the cell. The cell wall helps protect the cell against the environmental changes it it allows most molecules to pass through it. This layer is composed of molecules called peptidoglycans. Just inside the cell wall is a less rigid envelope called the plasma membrane also known as the cytoplasmic membrane. In bacterial cells the plasma membrane has two primary functions: it serves as a selective barrier to molecules that are penetrating the cell wall allowing

BIOL 3810-504 Compound Action Potentials Date Performed: 15FEB2011 Date Due: 01MAR2011 Introduction Neurons are the cells that receive and transmit electrical signals (University of North Texas‚ 2010). The ability of the neuron to conduct these impulses is because of an electrochemical voltage across the plasma membrane of that neuron. An action potential is an all or nothing response to a stimulus along a single axon. A compound action potential is a graded response that results from
