Our Last Week: The Final

Announcements

The final exam is this Friday December 17th at 1:30PM in Morrill Science Center room 222. The exam will cover the material since the last exam (Urinary, Endocrine, Digestive, and Immune systems) as well as some cumulative questions from the entire semester. The final written reports are due at the final exam.

Review sessions are scheduled for the following times in ISB 264.

Wednesday 12/15 10:00AM

Thursday 12/16 6:30PM

Suggested Reading

Chapter 20 Urinary System

Chapter 21 Endocrine Organs p. 686-698, 700-706

Chapter 17 Digestive System II: Esophagus & Gastrointestinal Tract p. 518-553.

Chapter 18 Digestive System III: Liver, Gall Bladder, & Pancreas p. 576-602.

Chapter 14 Immune System p. 396-407, 410-420, 424-429.

Week 13: Digestion and Immune Systems

Announcements

The course is winding down!

Our plan for the rest of the semester is to examine the histology of the digestive system and accessory organs (pancreas, liver, and gall badder) and finish up with the immune system.

    November 29 Digestive System
    December 1 Immune System
    December 6 Immune System
    December 8 Group Oral Presentations In class and In Wednesday Lab (see below!)

The third and final lab practical is scheduled for December 7th and 8th. The oral group presentations are also on December 8th. To make the day a bit more manageable, I will be serving a light lunch during class. Wednesday's lab will go directly to lab at 12:20 to take the practical then back to class when that is complete. In class, we will have Tuesday's lab presentations first, have lunch when the Wednesday folks reappear, and wrap up during lab time with any Wednesday presentations remaining.

Week 12: Digestive System

Announcements

This is a short week due to Thanksgiving; there is no class on Wednesday. Although there is no official lab, please take advantage of the opportunity to week to capturte of images of your project material.

Our plan for the rest of the semester is to examine the histology of the digestive system and accessory organs (pancreas, liver, and gall badder) and finish up with the immune system.

Immunohistochemistry this week!

Hi everyone,
This week we'll be doing immunohistochemistry on our sectioned tissue. You will find a description of the project under the Laboratory>Histology Lab Project link. You will also find a rubric there and a protocol we will use this coming week. Please bring a copy with you and have all your sectioning completed.

See you in Lab,
Bryan

Week 07: Muscle and Nerve

Announcements

This week we wrap up our investigation of the body's 4 tissues with discussions of nerve and muscle.

Lab this week is lab 5 Circulatory System and Blood. Our next lab practical will be on October 26th and 27th so remember to return to lab to review the slide material. We also hope to start sectioning your organ material this week!

Objectives

Describe with confidence the structure and function of muscle and nervous tissues.

Reading Assignment

The reading material is fairly detailed. In order to assess what you should concentrate on, I suggest that you refer to the Study Guide relating to each topic area.

Please read Chapter 6 (pages 146-192).

Week 05: Connective Tissue

Announcements

Our first exam is this week! Due to popular demand, the exam will be held in class on Wednesday, October 6th. The exam will cover all material covered through yesterday's class meeting (9/29); specifically it will be on histological techniques and methods and epithelial tissues (Chapters 1-5 in your textbook).

To help you prepare, we will have several Review Sessions in ISB 264 (aka lab). Please come prepared to ask questions; there is no formal review presentation. Review sessions are:

    Friday 10/1 12:20PM
    Sunday 10/3 7:00PM
    Monday 10/4 8:00PM
    Tuesday 10/5 5:00PM

Sample exams are available under Review Materials!

Our first lab practical is also this week! The practical will be based on the first three labs including Connective Tissue. We will work hard to have excellent examples of the cells and tissues for you to identify. The key to success is studying the material outside of lab. Please use the slide sets, online image galleries from this and past years, and practice exams from Bryan or at the links on this site under Review Materials.

After the lab practical , you will work on Lab 4: Connective Tissue. Please read the lab, found under the Laboratory link before you come to lab. PLEASE BRING YOUR TEXTBOOK TO LAB!

Objectives

    Understand the structure and function of connective tissues. Be able to discuss the molecules that make up connective tissues including glycoproteins, proteoglycans, collagens, and elastic and reticular fibers.

    Discuss the general categories of connective tissues and their ratios of fibers and cells.

    Describe with confidence the structure, function and occasionally the development of specialized connective tissues including blood, bone, adipose tissue, and cartilage.

Reading Assignment

The reading material is fairly detailed. In order to assess what you should concentrate on, I suggest that you refer to the Study Guide relating to each topic area.

Please read Chapter 6 (pages 146-192).

Immunohistochemistry Rat Tongue

Section of Skeletal Muscle of Rat Tongue stained with:
FITC green for actin (seen in core of muscle fibrils)
rhodamine red for Collagen Type IV (seen outlining muscle fibrils in endomysium)
DAPI blue for nuclei (seen pushed to the periphery of each muscle fibril)

Note: blue artifact in lower right corner, may be a knife mark. Also bright green artifact in upper right corner could be folding, unevenly cut tissue, or overstaining.
