The Physiology and Pathophysiology of the Skin Abstract The 5-HT3 receptor is a ligand-gated cation channel located in the central and peripheral nervous system; it has also been detected on a variety of other cells. In the periphery‚ it is found on autonomic neurons and on neurons of the sensory and enteric nervous system. In the CNS‚ the 5-HT3 receptor has been localized in the area postrema‚ nucleus tractus solitarii‚ nucleus vaudatus‚ nucleus accumbens‚ amygdala‚ hippocampus‚ entorhinal‚

CHAPTER 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY OBJECTIVES 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. 2. List‚ in order from least to most complex‚ the levels of structural organization‚ discuss the relationship between the levels‚ and name an example at each level. 3. List the 11 organ systems of the human organism‚ name the major organs within each‚ and give a general

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Anatomy is the study of the structure and shape of body and parts‚ while physiology is the study of how the body work and function‚ their relationship is seen for example in the heart‚ there are two valves (anatomy) and these two valves help the heart pump blood. 2. The atom is the smallest particle of an element. An example is carbon ( C ) which is the building block of life. A group of atoms could form for example‚ a water molecule

Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS

Chameleons Organism Physiology Brianna Kibler October 1‚ 2014 Principles of Biology BIO/101 Matthew Scholten Organism Physiology We know that an organism is anything that is living and can function by itself. This paper will help understand chameleons and how they have evolved to adapt to their surroundings. It will also discuss their physical features inside and out. Myths and facts will be revealed‚ as well as a few comparisons between sexes. Though there are many species of chameleons

ANATOMY AND PHYSIOLOGY The pelvis is a large semicircular bone complex that forms the base on which the torso and upper body are positioned. The pelvis‚ which is a rigid and inflexible portion of the skeleton‚ is built to provide a foundation of the movement of other parts of the anatomy‚ particularly the back and the legs. The pelvis also permits the weight of the entire upper body to be evenly distributed

1. Label a diagram of the respiratory system?? 2. Describe the process of breathing?? Breathing consists of two phases. The first is inspiration and the second is expiration. During inspiration‚ the diaphragm and the intercostal muscles contract. The diaphragm moves downwards increasing the volume of the thoracic cavity and the intercostal muscles pull the ribs up expanding the rib cage and further increasing this volume. This increase of volume lowers the air pressure in the alveoli to below
