Tissues: An introduction
Lab Report Part 1

This lab is divided into two different parts. Part 1 deals with the general characteristics of tissues, and part 2 asks you to interpret some photomicrographs taken of human tissue slides in our lab. Part one should be completed first, but you’ll probably get a lot of hints about the answers for part 2 if you’ve looked over the images and questions provided ahead of time to work on them. To do Part 1, download the following documents and have your textbook available.

Part 1 Characteristics of tissues
A. Epithelial Tissues
What are five general characteristics which distinguish epithelial tissues? (1. Cellularity: tightly packed sheets of cells with little intercellular material between them 2. Basement membrane; the basal surface of ETs are anchored to underlying CT by a distinct basement membrane 3. Specialized contacts: tight junctions and desmosomes 4. Avascularity: contain no blood vessels; are nourished by nutrients which diffuse upward from underlying connective tissue through the basement membrane 5. Regeneration: high regeneration capacity due to rapid cell division )

Explain how the general morphology of epithelial cells may be deduced from the names of the epithelial tissues. (The names of the epithelial cells are characteristic of their structure: simple=single layer stratified=many layers squamous=flat cuboidal=cube shaped columnar=elongated )

Epithelial tissues specialized for secretion can be found in two types of glands. What are the gland types, and what are the functional characteristics of each? (Exocrine glands secrete products into a duct, which opens onto and external surface (ie sweat gland) or an internal space/lumen (ie gastric gland). Endocrine glands secrete hormones into the blood and are ductless.)

Explain how the characteristics of any one of the epithelia help that

When your lab report is complete, submit this document to your instructor in your assignment box. 1. Endocrine System Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism? Answer 1: Insulin and Glucagon work in tandem to keep the glucose levels in the blood within the normal range. If someone if experiencing high blood sugar levels, the pancreas will begin to secrete insulin by way of the beta cells. As this is happening the liver will take up the glucose and store it as glycogen. Now in the reverse, if a person is suffering from hypoglycemia and has low blood sugar, the alpha cells located inside of the pancreas will begin to produce glucagon. This substance will be sent to the liver and begins the process of converting glucagon to glucose. 2. Cardiovascular System Blood flows through the body in two distinct pathways: the pulmonary pathway and the systemic pathway. The blood flowing in the pulmonary pathway is deoxygenated, and it delivers this blood to the...

Tissue Engineering Personal Statement

...want to conduct research in the area of tissue engineering, which primarily exists in the realm of research, and for that I need a Ph. D. A master's degree is a step on the way to earning a Ph. D. I am particularly interested in engineering of cardiovascular tissue. Specific research topics that I am hoping to work on include the creation of 3D scaffolds, the influence of mechanical forces on the differentiation of cardiac tissue, and the study of cytokines in the differentiation of cardiac tissue. I hope that one day it will be possible to grow whole hearts from a patients' own cells to replace their damaged or diseased hearts. This could effectively eliminate organ transplant waitlists for hearts. My interest in biomedical engineering over other science related fields stems from the fact that my mother is a nurse and my father was a lab technician while he was in the military. Sometimes he would take me to his work and I could see how the lab was set up. He would let me look through the microscopes and sometimes explain what he was doing. He would often tell me that he was surprised that I actually understood most of what he told me. Before attending UT, I earned a biotechnology certificate at Temple College. During the program I gained hands-on experience in many...

When your lab report is complete, submit this document to your instructor in your assignment box. 1. Endocrine System Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism? Answer 1: “Insulin and glucagon work together to keep glucose levels in the blood within the normal range. When there is an elevated blood glucose level, this stimulates beta cells in the pancreas to secrete insulin. The insulin facilitates the uptake of glucose by body cells, and the liver will uptake the glucose and store it as glycogen. These actions return blood glucose levels back to normal. When there is decreased blood glucose, this stimulates the alpha cells in the pancreas to produce glucagon. The glucagon travels to the liver and facilitates the conversion of glycogen to glucose. This glucose is released in the bloodstream to return levels back to normal.” (M.U.S.E.) 2. Cardiovascular System Blood flows through the body in two distinct pathways: the pulmonary pathway...

Nutrition Lab #1

...NUTRITION 121 HUMAN NUTRITION LABORATORY BACKGROUND AND METHODS MODULE #1 BODY COMPOSITION Late Labs: 10 point deduction! A report submitted >1 week late, will receive 0 points for the lab!! Written and edited by: Karon Felten and Nutrition 121 TA’s With Special Thanks to: Chris Pritsos Ph.D. Nutrition Department Chairman ABSTRACT: In nutrition, there are many factors that influence an individual’s health and body weight, such as heredity, food selection, eating behaviors, and physical activity. Scale weight is not always a good indicator of body fat, lean mass, body water or overall health (1). This laboratory experience will give students the opportunity to conduct physical assessments by evaluating body weight and body composition. To determine body weight and body composition, techniques such as bioelectrical impedance analysis (BIA), body mass index (BMI), waist circumference, wrist circumference for determining frame size, and a scale will be utilized. Students will also evaluate their own risk for cardiovascular disease and assess cardiovascular health in volunteers by measuring heart rate, filling out a heart disease risk score form, and estimating oxygen consumption and energy expenditure through a technique known as the Queens College Three-Minute Step Test. BACKGROUND: Your body is made up of the six essential nutrients: water, fat, protein, carbohydrates and various vitamins and minerals. Many factors can influence an individual’s...

Stem Cell Research: a Road to Recovery

...Stem Cell Research: A Road to Recovery Lisa Wainwright Kaplan University CM220 Stem Cell Research “Recent studies suggest these cells may hold the secret to treatment — even cures — for some of our most baffling diseases, including Alzheimer’s and Parkinson’s.” (Reaves, 2001) With constant development in science and medicine, it was only a matter of time before scientists and doctors would be on the verge of finding cures for diseases that people everywhere have been waiting for. Stem cell research began around 1981, when scientists discovered controllability in the development of mouse embryos; however, it wasn’t until 1998 that scientists discovered how to originate human stem cells from embryos and cultivate them in a lab. (U.S. Department, 2009) President Barak Obama signed Executive Order 135005, “Removing Barriers to Responsible Scientific Research Involving Human Stem Cells,” on March 9, 2009. Section 1, Policy, reads, “Research involving human embryonic stem cells and human non-embryonic stem cells has the potential to lead to better understanding and treatment of many disabling diseases and conditions. Advances over the past decade in this promising scientific field have been encouraging, leading to broad agreement in the scientific community that the research should be supported by Federal funds…. including human embryonic stem cell research, to the extent permitted by law.” (Obama, 2009) There are those who argue that stem cell research should be limited...
