INTRODUCTION

Preparation. The key to success in this lab is preparation! Prior to each lab you should prepare by completing the reading assignments and the written lab manual exercises, studying the appropriate tables and figures in your books and syllabus, and writing out definitions to terms to know in your syllabus. An appropriate definition in anatomy and physiology will often include information on the location, structure and function of a particular structure or the effectors, dynamics, and regulation of a particular process or function.

It is strongly suggested that you enroll in BIOL 238 and 248L concurrently. These are two components of the same course. They are designed to complement and reinforce one another in course content. In any case you are well advised to purchase and use the textbook for BIOL 238, or a comparable up-to-date text, in addition to the lab manual for reference, review, and terminology.


 

This Lab utilizes WebCT for assignments and online quizzes, as well as many other resources. 

Student Equipment. We suggest that you purchase a blunt probe and you must purchase vinyl examination gloves to use with the cadavers. You will not be able to effectively study anatomy on the cadavers without them. Both of these items are available at either of the UNM bookstores. You will need around 15 pairs of vinyl gloves over the course of the semester. We suggest that you purchase a number of these and carry them in your book bag so that you do not forget them. Many students purchase lab coats. Cadaver work can leave stains and odors on clothing. Lab coats can be purchased at the North Campus bookstore or at uniform or medical supply stores around Albuquerque.

Lab Materials. Cadaver study will be a vital part of your education. They give a three-dimensional perspective and allow hands-on learning that simply cannot be obtained from diagrams. Due to the cost of using cadavers, many schools have eliminated them from their curricula. Since we use four cadavers for around 500 students each semester, special care must be taken to preserve them as well as our other materials. Do NOT use pencils and pens as probes as these will mark and damage the specimens. The markings around the foramina of our teaching skeletons are evidence of the abuses of the students that came before you. Do not use the labels on the cadavers as handles because many of the structures are fragile and will tear. The cadavers must be kept moist with wetting solution at all times and they should be covered when not in use. please be conscientious in spraying and wrapping cadavers for the benefit of all students using them.

Obviously, with this many students using so few cadavers we cannot actually dissect the cadavers in this class. The dissections are done by students enrolled in a biology class called Prosection (BIOL 447). If you would like to study anatomy in greater detail after taking this course, you are invited to apply for enrollment in prosection. See the course coordinator for further information and an enrollment application.

Special caution must also be taken when using microscopes. With the financial condition of the University, what microscopes we have are very difficult to replace. Take care when carrying microscopes. Be careful not to jam the lenses onto the slides, and be sure that you use only oil on the oil-immersion lenses, and lens cleaning paper on the lenses. The prepared histological slides are also expensive and easily broken. Be careful that you do not drop them or jam the lenses down onto them. Partially as a response to these problems we have developed the Virtual Microscope®, an online tutorial and collection of microscope slides from your laboratory which are available in the laboratory and to any computer with an internet connection.

  To make it easier to study outside of the lab many of the models and specimens used are pictured in WebLab, an interactive tutorial similar in format to the Virtual Microscope®

Examinations. Questions for examinations will be drawn from laboratory exercises from the lab manual, lab lectures given by your T.A., and reading assignments from the text. Use this syllabus as a guide of the depth of knowledge required in this class. The "Terms to Know" lists are the minimal level of knowledge required for a passing grade. Many of the terms are found in the text for BIOL 238.

PRECAUTIONS & REQUIRED MATERIALS

PRECAUTIONS:

Cadavers are preserved in a mild solution of formalin (which produces formaldehyde in water) and phenol, intended to inhibit the growth of microorganisms. Both of these are toxic and extended exposure should be avoided. The effect of formalin is mostly as an irritant in the respiratory system and mucous membranes. Although formalin is a suspected carcinogen, studies have not shown it to be mutagenic or teratogenic, i.e., it has not been shown to cause cellular mutations or birth defects. Phenol is a caustic substance that also can burn the skin and mucous membranes.

The wetting solution used in our cadaver lab does not contain these substances. Instead it contains phenoxyethanol and glycerin in water. These substances retard growth of microorganisms while helping to reduce the dessication of tissues. Phenoxyethanol is toxic when ingested.

Exposure to all of these should be limited in the following ways:

1) Gloves and protective clothing: gloves should be worn at all times when using the cadavers to avoid skin exposure. Students must provide their own gloves. Students should wear a lab coat to protect skin and clothing from contamination and stains.

2) Proper ventilation should be maintained by keeping the exhaust system on high when the cadavers are in use, and using a fan to circulate air over the cadavers. If close work with the cadavers results in burning sensation of the nose or eyes, cease the exposure. Pull back away from the specimen, adjust the air flow, or take a break to get some fresh air.

3) Students wearing contact lenses may find it necessary to remove them when working in the cadaver lab. Permeable contact lenses may absorb formalin and cause irritation to the eyes.

If you have any condition that might be affected by exposure to any of the above agents, or which may affect your lab participation in any way, do the following:

1) Notify your lab instructor: your instructor can advise you of ways to minimize the impact on lab work. Also, your lab instructor can be prepared for any situation that might arise.

2) Consult your physician: your physician can give you the best information on what effect the preservatives, etc., may have on your condition and help you to make an informed choice regarding continued participation in the lab.

TEXTS AND OTHER REQUIRED/OPTIONAL MATERIALS:

Required: Human Anatomy & Physiology Laboratory Manual, Elaine Marieb, 6^th Edition. References to exercises in this syllabus are to the above.

Strongly Suggested but Optional:

*1)  Adam Interactive Anatomy Student Lab Guide. Benjamin-Cummings. This is available bundled with the above laboratory manual at a substantial savings off the individual price.

2) Anatomy Coloring Book, Kapit & Elson;

In addition to the above lab manual, students are required to purchase gloves for use in the cadaver lab and with other preserved specimens. Gloves may be obtained at the medical bookstore or at pharmacies, surgical supply stores, etc. Several students can usually split one box of gloves for the entire semester, bringing a pair or two each week for use in the lab. Students are advised to wear a lab coat to protect skin and clothing from contamination and stains; these may be purchased at the bookstore or at uniform shops, etc. Drawing paper and pencils are advised (see instructor for types preferred) for in-lab histology drawings.

ADAM Interactive Anatomy is a computer program for studying anatomy of the human body. It will be used as an supplement in the laboratory and is available on the laboratory computers. Students may also purchase the student version as a CD ROM for use at home. Where you see the above symbol you will find general directions for what to study. Use of the Adam Interactive Anatomy Student Lab Guide will allow students to follow a more precise plan in their study.

Interactive Physiology

ADAM Interactive Physiology consists of 7 CD ROM disks covering the major body systems. It is available online with purchase of a new Human Anatomy and Physiology, 6th Edition,  or independently. Disks will also be available for student use in the laboratory.

Each laboratory session will normally begin with a Powerpoint™ presentation illustrating the tissues and organ system to be studied. These presentations are available on the web at: http://biology.unm.edu/anatomy/ppt.htm Also linked to this page are histology and pathology slides, lecture class notes, and this manual.

USE OF THE PROPER (WINDMILL TYPE) SPIROMETER

A simple windmill-type spirometer can be used to reliably measure vital capacity. It cannot be used to accurately measure other lung volumes or to determine FEV (see manual).

To use the spirometer, attach a clean mouthpiece and turn the outer ring until the dial says "zero." While standing, take a few practice breaths and then inspire maximally (not through the spirometer!), followed by a maximum expiration through the spirometer. Really push! The best readings are obtained by blowing very hard. Take the best of three trials and compare these with normal values seen on the charts provided.
