Document Summary

Module 1 basic anatomical organization and histology. Readings: atlas a, atlas b, chapter 5 (5. 1-5. 5) This module will introduce you to the study of anatomy. It will begin with a short history of anatomical study and go into some of the modalities used in the study and evaluation of anatomical structures today. We will learn some of the basic directional terms used to describe the orientation of the body. These terms will be used throughout the course as anatomical structures are meaningless without an understanding of orientation and location within the body. Then we will look at histology, the study of tissues and how tissues make up organs. This first module will serve as a foundation for future sections. As we move through the body systems we will look at cell and tissue structure and how this relates to function of the various anatomical structures.

Scenario 5:
You are trying to image some structural feature or biochemical event within a thick tissue sample or within a restrained/anaesthetized small animal (e.g. a mouse). You need to achieve spatial resolution of ~10Î¼m to resolve cellular organization or signal from individual cells, and this needs to be at a depth of several 100 Î¼m, but imaging time is not a major limitation (the sample again is live although stationary). Issues to consider include limitations for imaging deep within a tissue sample and how image geometry and sample size affect which modalities can be used (i.e. tissue within an animal compared to isolated thick tissue sample)

The scenario describes commonly encountered problems in applying fluorescence microscopy to study biological samples. I would like you to discuss ways of overcoming the problems at hand.
-What is the cause of the fundamental limitation(s) present in the problem when using a conventional fluorescence microscope system (wide field microscope or regular confocal microscope)? What are the tradeoffs (e.g. photobleaching, acquisition speed, spatial resolution, signal, noise and background, or other factors) that provide practical limitations?

-What type of optical imaging approach, technology or strategy could overcome these problems?

-What light source, optical detector, fluorophore and other key instrumentation/reagents will be needed and why? (you may want to provide specs for specific products where relevant).

-How will this strategy work and how will it generate new information about the object/process being studied: e.g. will fluorescence intensity be measured, or fluorescence lifetime, or scattering, some other property?

-What other limitations could there be in the approach planned? Can these also be minimized and how?

List the levels of organization from smallest to largest. Provide a specific example for each level.

Compare/Contrast sections and planes.

What are the distinguishing characteristics of the anatomical position?

Practice placing a section through a location in the body and then determine what structures would be made visible by that section in that location. For example if a coronal (frontal) section were made in the thoracic region (would be able to see both lungs, the heart, depending on the exact location of the cut, maybe the esophagus and /or the trachea)

Practice the directional terms using them to describe the locational relationship between two body regions (use the technical terms for those body regions, (i.e. if the original post used __ is superior to blank, the opposite would be ___ is inferior to __).

Distinguish between the nine abdominal regions and four quadrants and indicate what major organ(s) would be found deep to that region or quadrant.

Why is it important to study the language of anatomy and physiology if one is going into the medical field?

Define homeostasis. What thing (or things) in our body maintains homeostasis? And what regulates those "things"?

What is the likely result if homeostasis is not maintained?

13. What are the components of feedback mechanisms? What is the function of each component?

14. Discuss negative feedback mechanisms. Give a specific example of one.

Discuss positive feedback mechanisms. Give a specific example of one.

Discuss the levels of organization, list the various levels and provide a specific example of each level.

What is matter?

What are elements? What are the four most common elements of the human body?

Distinguish between atoms, and molecules. Provide an example of each.

What information is provided by the molecular formula? For example what can be said of the formula C₆H₁₂O_6, the molecular formula for glucose?

Briefly distinguish between organic and inorganic molecules. Recall that MY preferred defining quality differs from what the text says!

Consider/review the important inorganic molecules discussed in chp 2 and describe their importance in the human body.

Distinguish between acids and bases. Which of these will have relatively more free H+ ions?

What is the pH range of an acid? Of a base? What would be the pH value of a solution where the number of H+ ions = OH- ions?

What are the states of acidosis and alkalosis with reference to blood pH values?

Consider/review the important organic molecules discussed in chp 2 and describe their general importance in the human body.

Distinguish between solvent and solute.

Discuss the term osmolarity.

Consider/review the four types of lipids and discuss their individual function in the human body. Lipids are not composed of monomers but they do have âbuilding blocksâ, what are these building blocks?

What are the "building blocks" or monomers (looking for a group or class name) of a carbohydrate polymer? Name the five (5) types of carbohydrate monomers.

When two of these carbohydrate monomers are bonded together what "class" of carbohydrate is formed? What are the types of this "class"? What is the source (food) for each of these?

When three or more of these monomers are bonded together they form which "class" of carbohydrate? Which one of these stores excess carbs in animals (mainly in the liver)? Which one stores excess carbs in plants? And which one is indigestible by the human gut, but is important because it provides "bulk" in the form of fiber and helps keep fecal matter moving in the intestines?

What is the monomer of nucleic acids?

Briefly describe deoxyribonucleic acid including its general function.

Briefly describe ribonucleic acid including its general function.

What are the monomers of proteins? What kind of bond holds the monomers together?

Distinguish between oligopeptides and polypeptides.

Choose TWO general functions of proteins based on the globular vs fibrous classification of proteins, the class of protein that performs that function and a specific example for each.

What are enzyme co-factors and what is their role in enzyme action?

How are enzymes regulated?

PURPOSE: To examine the genetic, Biochemical, and Cell biological mechanisms of disease development.

In class we have focused on many of the fundamental principals and techniques of genetics and molecular biology. For this assignment I want you to see how these ideas are applied in studying genetic diseases. In addition, I want you to get insight into the experimental design and procedures that are used for expanding our understanding of genetics and how they are applied to studying and treating human genetic diseases.

The goal will be a final research paper that will be due by the last day of class (April 3, 2016). An outline of what is expected to be presented in the paper is listed below.

Paper Guidelines: Review of a Specific Disease

Components:

A. Clinical Features of the Disease

ï· Age of onset
ï· Male/ Female predominance
ï· Clinical symptoms and pathology ï· Population distribution

B. Genetics/ Transmission

ï· Spontaneous/ Inherited
ï· Inheritance distribution
ï· Identification/ isolation of gene/ loci ï· Mutation of gene

C. Molecular Pathology

ï· Effect of mutation on structure/ function of protein
ï· What/ how pathways are affected
ï· Effect on development/ function of cells, tissue, and organs ï· How gene(s) is related to clinical manifestations
ï· Animal models

Please note that all of the information may not be available or understood for your disease. I expect each of the sections to be addressed in the paper (A., B., & C.), however the subtopics (identified by bullet points) may not be understood. I would like the paper as complete as possible, however the final content will be determined by what is currently known about the disease.

You will accomplish this in three steps. A description of each step and the due date are presented below.

1) Choosing a disease.
Due Date: Sunday March 13, 2016

I want you to identify a human genetic disease and provide a very brief overview of the disease (Section A). I want you state how the disease is inherited (Autosomal dominant, Autosomal recessive,

etc) a brief description of the clinical features and the gene that is mutated (if known). This assignment should be no more than 2 pages and is worth 50 points towards your final grade.

2) Identify an experimental journal article. Due Date: Sunday March 20, 2016

I want you to identify a published research journal article that examines the genetic disease that you have chosen. The paper must have been published within the last two years. The paper must present experimental evidence that is relevant to your disease. I want you to submit the paper to me as well as write a one page summary of what was learned by the research study and how it applies to the understanding of the molecular pathology of the disease (Section C.). You can search for a journal article using the resources of the library. I would also like you to choose one experiment (figure) in the paper and describe what experimental techniques were used for that part of the study. This section should not exceed 1 page. This is worth 50 points towards your grade.
