Cell and Tissue Biology

Welcome to the Cell and Tissue Biology home page!

This course explores microanatomy and the many fascinating links between form and function at the microscopic level. To be successful in the M2 pathology course, you must be able to recognize and understand the function of normal cells and tissues. This is the main objective of this course.

The major components of this course are: 1) textbook reading assignments ("Histology, A Text and Atlas, 7th Edition", Pawlina), 2) web-based laboratory excercises, 3) lab meetings during which you will use microscopes and virtual microscopy to look at tissue sections and work together in small groups on clinical cases, and 4) course lectures.

You are expected to have completed the reading assignments BEFORE coming to lecture. Lectures will amplify and extend some of the material covered in the reading assigments.

I just made the clinical case assignments for CTB II. Cases will be presented by students during Lab 7, 8 and 9. You can find you assignments by going to the CTB course web site, navigating to the "Labs" tab, and then looking for the link called "desk and case assignments." Here is the direct link: Desk and Case Assignments You should find and check on you assignments right now so you know when you are presenting. If there is an error (i.e. you are not scheduled to present a case), let Dr. Ben Williams know so he can make any necessary corrections. This is the time to check your assignment. There are no excuses for a missed presentation.

If you need to swap labs with another student, you can do this using the swapping software on the desk and case assignments page. Just follow the instructions given at the top of this page. IMPORTANT: You may only make symmetrical swaps. In other words, if you want to swap sections with another student that involves a clinical case presentation, then both of the assignments involved in the swap need to be clinical case assignments. The same is true if the swap involves a peer evaluation assignment: both assignments in the swap should be for peer evaluations.

CTB II Information Sources for Histology:
Textbook: "Histology, A Text and Atlas, 6th Ed." by Ross and Pawlina
Lecture notes and published powerpoint slides
Lab notes from the Web based Atlas (by Dr. Williams)

Khan Academy: http://www.khanacademy.org

The second semester of Cell and Tissue Biology will be organized similar to the first semester. Lecture and lab materials will be made available online as they are completed. The first lecture is Jan. 4, 2015, 11 am.
The study guide lists the structures to identify, define, and to describe their locations and functions. A few example questions will also be included.
Progress exam 4 will be held Feb 2 and will cover everything through the Urinary System. All questions will be single best answer and may or may not have photomicrographs for identification. The final exam, March 17, will be comprehensive and comparative across all organs studied in the Spring semester. On the final exam, every question will be related to a photomicrograph of the tissues. A short practice exam will be arranged online prior to each exam.

The textbook "Histology, A Text and Atlas, 6th Edition", by Ross and Pawlina will be used as a supplement, which can be very helpful in providing explanations and backfilling information from the lectures. Lectures will provide the basis for the exams but the textbook will be able to provide far greater detail.
CTBII Lectures are for 50 minutes, which unfortunately is not enough time in which to reveal all the facts needed for this course. The best that a professor can do is try to get your attention and hopefully you will find the desire to complete the discovery process. Therefore, the Powerpoint slides will be split into “Lecture Notes” and “Outside study slides.” Hopefully we can complete the first part in class; however, regardless, we will stop after 50 minutes. You will be held responsible on exams for all powerpoint slides (Lecture and Outside study) and associated virtual slides linked to your labs. The virtual slides used in the laboratory atlas will be used for photos included in the exams, because they provide better contrast for tissue recognition.

If you have any questions, please email: rexhess@illinois.edu. My cell phone number will be provided in class or by email. I look forward to working with you this semester and wish you the best.

I have managed to get behind a lecture. To make sure that I cover all the material in class before your final, I added a lecture at 8 am on October 27. I will cover "Skin and its Derivatives" during this session. Skin will be covered as part of lab 4, which meets today and on Monday and Tuesday, Oct 17 & 18. Because "Skin" has not yet been covered in lecture, it would be a good idea to skim through the reading assignment for the "Skin" lecture before attending lab. For highest yield, you can just review the following 5 figures from your textbook before lab: 15.2, 15.3, 15.4, 15.12 and 15.13.

There will normally be a proctored review session for each of CTB lab quizzes, scheduled a few days after each quiz.

Lab quiz 1, which was for practice only, will be handled differently. You can now review your quiz 1 results on-line. Go to the on-line exams link on the main M1 page of the UIUC-COM website, scroll down to CTB. If you took quiz 1, you should see a button called "review exam" next to a text window for a password. The password is "review", all lowercase. Enter the password and click the button.

Your review session will be timed. You will have 15 minutes from when you start. You should be able to advance through the questions, look at the answer that you submitted, and compare it to an answer key. In some cases, you may receive feedback for an incorrect response.

Pat Grenda has also just posted your grades for lab quiz 1. Remember: this quiz was for practice only, so these scores do not count for course credit.

Good luck with your preparations for tomorrow's CTB exam.

The best way to move your case presentation to the computers in the 3rd floor MSB classrooms is to use "Box." All students should have a "Box" account though the University of Illinois. Here's the link:

https://box.illinois.edu/

Another option is to copy your presentation to a USB key.

I just put up a link to the podcast of Vanessa Peters giving a demonstration clinical case presentation. The link appears near the top of the "Labs" page within the CTB web site.

I also put the link right here: https://www.med.illinois.edu/podcasts/podcast.php?eid=63565

I made a mistake entering the times for the lab 2 meetings next week. All lab sections for lab 2 will start at 3 pm and run until 6 pm.

This error has now corrected in the "case presentation / lab seating" web page that I emailed you about yesterday. The Lab 2 times should now be accurate on this web page.

I apologize for the error and any confusion/concern that it may have caused you.

Note that all meetings for CTB labs 3, 4 and 5 run from 1 pm to 4 pm. Lab 2 is the only exception. See you next week starting at 3 pm!

I have just posted your clinical case presentation assignments for CTB I. Go to the "Labs" tab in the CTB course web site, and click on the following link: "desk and case assignments." This link appears near the top of the page.

1) Please check to be sure that you have only one case presentation assignment for this semester, and that your assignment correctly falls on a date that you are scheduled to attend lab. If not, let me know as soon as possible so I can correct the error.

2) Please put your presentation date in your calendar now, and plan accordingly. Excuses for missed presentations are limited to those negotiated through the Office of Academic Affairs. These are normally limited to medical and family issues. "I forgot" will not be accepted as an excuse.

3) The web page that shows your assignment includes an application that will allow you to swap lab sections with other students, if you discover that you have scheduling conflicts in the future. Please read the instructions carefully. All swapped lab sections must be registered via this web page. This is so we know who will be attending, can make sure that that we adequate space for everyone, and can properly assign peer evaluations within the evaluation software. If you need to swap lab when you are scheduled to present a clinical case, you can only swap with another student who is also presenting. In other words, all swaps must be symmetric.

4) If you have any questions about any of these procedures or policies, please ask them as soon as possible so we can clear up any confusion.

The first CTB lecture is Tuesday August 16 at 9 a.m. in the MSB Auditorium. Please read chapter 1 of the textbook (Pawlina, Histology, "A Text and Atlas", Seventh Edition).
