CHAPTER ONE ANATOMY - Studies the STRUCTURE of body and their relationships to one another. SUBDIVISIONS OF ANATOMY GROSS ANATOMY - the study of large body structures visible to the naked eye. Regional Anatomy - all structures in one part of the body are studied at the same time Systemic Anatomy - various systems of the body are studied. MICROSCOPIC ANATOMY - examination of body tissue using a microscope. CYTOLOGY - study of the CELLS of the body. HISTOLOGY - study of the TISSUES

and therefore the crude solid must be purified. This purified product is what is later put into the analgesic. In this experiment‚ the procedures that are important are vacuum filtration and recrystallization which are both used to obtain the Acetaminophen product. When collecting products‚ it is important to know how much product is left and what is lost through the experiment. To do this‚ the balanced equation will be looked at and then the theoretical yield will be calculated. In order to calculate

1. During the install‚ the option to sync with NTP (Network Time Protocol) server was checked. From a security perspective‚ why is it important for a system to keep accurate time? UNIX systems base their notion of time on interrupts generated by the hardware clock. Delays in processing these interrupts because UNIX systems clocks to lose time slowly but erratically. These small changes in timekeeping are what the time scientist call jitter. The Time protocol provided a server’s notion of time in

ANATOMY 2 LAB 1 – RECEPTORS Questions: 1. How is the distance between receptors related to sensitivity of a stimulus? * The greater the distance between receptors and stimulus the lesser sensitive are the stimulus. The smaller area‚ the more sensitive. 2. What does the two-point discrimination test measure? * It measures the smallest distance at which two points of contact can be felt or measures areas that are more sensitive and has more motor interactions. 3. What areas of

BALANCE LAB Introduction The purpose of this lab is to become familiar with how to use the ChemLab program for determining mass using both the centigram balance and the electronic balance. Using the centigram balance‚ the mass‚ in grams‚ of a copper slug will be determined by both direct weighing and weighing by difference techniques. Using an electronic balance‚ the wight of a copper slug will be determined by also utilizing direct weighing and weighing by difference. Average mass of a
