Department of Biological Sciences Comparative Vertebrate Anatomy Room # 123 The Origin of Chordates Reginald Bushner February 15‚ 2013 1 Abstract The word chordate originates from the word chorda or cord. Chordates are a very large group of animals with backbones. These animals have backbones or spines and inside are spinal cords‚ and an internal skeleton as part of their nervous system. It is believed that chordates have originated from invertebrates. It is difficult

HUMAN ANATOMY AND PHYSIOLOGY AN INTRODUCTION TO RESPIRATION In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some

Anatomy of contemporary GSM cellphone hardware Harald Welte April 16‚ 2010 Abstract Billions of cell phones are being used every day by an almost equally large number of users. The majority of those phones are built according to the GSM protocol specifications and interoperate with GSM networks of hundreds of carriers. Despite being an openly published international standard‚ the architecture of GSM networks and its associated protocols are only known to a relatively small group of R&D engineers

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. Anatomy: The branch of science concerned with the bodily structure of humans‚ animals‚ and other organisms‚ esp. as revealed by dissection. Physiology: The branch of biology that deals with the normal functions of living organisms and their parts. Anatomy and physiology are connected in

Anatomy literally means “to cut” – tomy and “apart” – ana‚ since in the early days anatomists used cadavers to cut apart and see inside. Physiology literally means the “study of nature” so we study the nature or functions of the body systems. We have to understand that the structure of any body part – muscle cell contracts the organ‚ protein fibers contract the muscle cell – all the way down to the molecular level‚ will affect the function of that part or molecule! We learn the anatomy of
