ANNOUNCEMENTS Flu can include: fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, and fatigue Preventing flu Get vaccinated. Wash your hands often. Cough or sneeze into a tissue or your elbow instead of into your hands. Avoid touching your eyes, nose or mouth, to reduce the spread of germs. Don't share food, drinks, utensils and other similar items. If you’re sick, stay home!!! me about your situation and we will work it out.

OBJECTIVES #1- ANATOMY: To understand the structural basis for the functioning of a living organism Close relationship between structure and function

ANATOMY GROSS ANATOMY (macroscopic) HISTOLOGY (microscopic)

OBJECTIVES #2- TECHNICAL ADVANCES: To appreciate that our ability to answer questions is driven by the development of new technology

Why study histology? What are the uses of histological techniques and microscopic tissue identification ?

Tools of the Histologist

Requirements: Tissue Preparation Start with an organism: Organ->Tissues-> Cells-> Molecules fixation/sectioning/ staining Imaging (Microscopy) Interpretation - cell biology - physiology - structure of tissues - organ structure/function Visual Integration **A challenging skill**

Teaching Assistants: Bryan Undergraduate Lab Assistants

Required Textbook: Histology: A Text and Atlas, Ross, Kaye, and Pawlina 6 th Edition, Lippincott Williams & Wilkins ISBN *** BRING TEXTBOOK TO LAB ***

Laboratory Experience (120 Points) Group Lab Project #2 Sectioning and staining of frozen and paraffin-embedded tissue of a rat organ. Techniques: microtome sectioning, frozen sectioning with cryostat, staining, immunohistochemistry, fluorescence microscopy, bright field microscopy, imaging, image processing. Assessment: Group Oral Presentation: In class (10 pts) Individual Written Project Report: (20 pts)

First lab: Tuesday, January 31 st or Wednesday, February 1 st To prepare for lab- Read Lab 1: Microscopy and Imaging Think about project partners (3/group)

Secrets of Success -Attend every class and every lab. -Come to class and lab prepared. -Ask questions. -Complete all assignments. -Review & study material after each lecture. -Answer review questions. -Attend help and review sessions. -Identify study partners.

ACCESS TO ISB 264 Exceptions: it will be in use by other courses on: Monday and Thursday 1:25pm-4:25pm Friday 3:35pm-4:35pm ……….And some other times to come

Challenge: Identify tissues. (Epithelial, Nervous, Muscle, Connective Tissue) Identify composite of tissues as an organ. Use appropriate descriptive language and terms. Understand the appropriate use of techniques to study material at the histological level

Orientation and Plane of section

CROSS SECTION LONGITUDINAL SECTION

Challenges of Interpreting Plane of Section = Organ= Surrounding Tissues

Challenges of Interpreting Plane of Section = Organ= Surrounding Tissues

Staining techniques

Magnification, Details of structure
