HUMAN ANATOMY

• 1) Why I chose this book Human anatomy, write by Elaine N. Marieb and Jon Mallatt, is because I will use it in my future goal that I will study DMS (Diagnostic Medical Sonography). It has so much details and graphics with their names or appropriate indications. Also it has explanation of the graphics, so that I am looking to star familiar with medical terms and names of the human body.

• 2) The strategies that I used were skimming, highlighting special names (concepts) and read again. To understand the book I had used the dictionary and it was a good helper. Sometimes I guessed and kept going, because later on I will know if I really will need those news names or part of the body.

• The obstacles that I had was the short time (I was reading in my lunch break on my job), and the new names or concepts, because using all the time the dictionary was one of the obstacles (specially).

• 3) According to the authors they want to show how the human body is structured.In this chapter they show the anatomical terminology, some are in Greek and Latin names. Also the levels of the structural organization of the body like cellular, tissue, organ, organ system and organism.

• The cells are the smallest living units in our body, and act as a fragile barrier, are proteins and can be replicates themselves. The cells have three main parts which are: the plasma membrane, the cytoplasm and the nucleus.

• The Plasma Membrane is lipid molecules with protein dispersed in it, and also is protective barrier that determines what leaves and enters the cell.

• The Cytoplasm is a cell forming material, and is viscous substance. It can divide in three important elements which are Cytosol, Organelles and inclusion.

• The nucleus is what contains genetic material deoxyribonucleic acid (DNA) and is the control center of the cell.

• Embryology studies prenatal period (38 weeks), and helps you to understand the organization of the human body and defects of the fetus. During the embryonic period, in special the first 8 weeks, it can show skin, trunk, muscles, vertebral column, spinal cord and brain, the heart, kidneys, gonads, and limbs.

• From the beginning of the fertilization it show us how the cell gets multiplied in pairs until the 4th day. At that time it is call morula. Then it enters the uterus, and it implants in the uterine wall. By the 3rd week it starts to form in layers that become the future body cavity. However the authors show that in the 4th week parts of the head and the tail, as well the tubular part as a body. Between the 5th through 8th weeks almost the embryo becomes as a human body with the eyes, ears, nose and limbs formed.

• Tissues are collections of structurally similar cells with related functions, and also contain nonliving material between their cells. There are four primary tissues:

• Epithelium (Covers body surfaces and lines body cavities).

• Connective tissues (Cartilage, bone and blood).• Muscle (long muscle cells “fibers”). • Nervous tissues (Nervous system).

OPINION

• 4) I know I haven’t finished this book, because it has 707 pages. I will continue reading this book and really I do like it. This book is well done. The presentation of it shows us graphics and I can say the authors had worked hard writing this book. So for this reason I give 5 stars and I congratulate to them.
