Need help with tissues drawing and labeling.

Assignment: Tissue Drawings
The intention of this assignment is to help you learn to distinguish/identify tissues. Your finished work should
convince me that you could do so.
When assignments are completed as instructed, this greatly speeds/facilitates grading. Please follow all of
these instructions or points will be lost.

• Tissues must be drawn such that structures are recognizable. Shape and shading of structures
are important.For example, squamous epithelial cells should be flat

• Divide each page into four quarters for four tissues per page. Please use only one side of each page.Any
type of paper is fine (no fringes from notebooks, please).

• Tissues should be on the page in the order of the list on the next page of this assignment.

• Tissues should be labeled clearly with full and complete name of tissue type & subtype.

• If there is more than one tissue type in the picture, label the specific tissue you are trying to depict by
pointing to it with an arrow and/or by using brackets to show the labeled tissue.

• Indicate the special features/structures on the list clearly by labeling and pointing to them.

• The drawings should be clear & neat with the tissue type easily recognizable. They do not have to be an art
project.

• Color is not necessary. The assignment can be done in pencil, pen, cave pigment…it doesn’t matter.

• Extreme detail is not needed, but it should have enough detail so that I can id the tissue.Structure, shape,
arrangement etc. is what is important.
You will submit your drawings as one single PDF document.

• Take a good photo or scan of each page.

• Insert all of the images, in order, into a word document –one of your pages per page of the document.

o There are extensive instructions on how to do this in multiple word processing
programs in this folder.

• Save as a single PDF document titled “Your last name first name drawings”

• After you have created the document, please check that the images and labels are clearly visible & that the
pages are in order.

o It is your responsibility to check: If they are not clear I will grade the submission as is

Using the photos provided of IHCC slides (not from your textbook or atlas! = no points), draw
the tissues below, including underlined structures when indicated.

Drawings should reflect how tissue appears at 400x magnification.Total points = 16 points
(1/2 point for each tissue or feature labeled)
Epithelium (4 points)
• Simple Squamous Epithelium
• Stratified Squamous Epithelium
• Simple Cuboidal Epithelium
• Simple Columnar Epithelium (label goblet cell)
• Pseudostratified Columnar Epithelium (label cilia)
• Transitional Epithelium

Connective Tissue (7 points)
• Areolar Connective Tissue
• Dense Regular Elastic Connective Tissue
• Dense Regular Collagenous Connective Tissue
• Dense Irregular Elastic Connective Tissue
• Dense Irregular Collagenous Connective Tissue
• Reticular Connective Tissue
• Adipose Connective Tissue
• Osseous (Bone) Connective Tissue
• Blood Connective Tissue
• Hyaline Cartilage Connective Tissue (label chondrocytes and lacunae)
• Elastic Cartilage Connective Tissue
• Fibrocartilage Connective Tissue

Muscle Tissue (3.5 points)
• Skeletal Muscle (label nucleus and striations)
• Smooth Muscle (label nucleus)
• Cardiac Muscle (label intercalated disc)

Nervous Tissue (1.5 points)
• Nervous Tissue (Label neurons and neuroglial cells)
Histology Photos
• These are photos of our (IHCC) actual slide
collection.
• What you would view if we had in-person labs.
• Use these to study for exam and to create your
Tissue Drawings.
• Test images will be from our collection only.
• Tissue Drawings must be from our collection only.

Histology Photos
• Remember: Tissues do not exist in isolation!
Organs are made of multiple tissues.
• Slides are taken from real structures/organs,
therefore a microscope slide rarely shows one tissue
type!
• Most of these slides will show multiple tissue types.

If I told you I saw deer in this field, how would you
look for them?
3
Would you zoom in and start like this?
Nope, tree trunk.
Nope, grass
etc
This would take forever, and you might miss something.
4
Better to start with the big picture, scan the meadow,
find potential deer, then zoom in

Histology in Practice
When studying histology (or anything with a
microscope), one of the most important skills to learn
is how to find something on a slide.

Histology in Practice
• Follow the same approach as you did with the deer:
SCAN FIRST!
• Use the scanning objective lens (4x) to get a “big
picture” of the organ/structure on the slide
• You may see multiple tissues!
• Use your knowledge of tissue locations to determine
which may be present
• e.g.Is this part of the lung?What type of epithelium could you
see?
10
Histology in Practice
• When you find an area of interest, then you will
zoom in with 10x, then 40x objectives
• We will not use 100x (oil immersion) objective in this
lab.
• Always remember to mark total magnification in
your notes and assignments.
“40x” implies total mag = 40x
“4x objective” implies total mag = 40x
11
Histology in Practice
• These photos will be of organ slides.
• Each may have multiple tissues
• This presentation will follow practical sequence:
• Scan, low power, high power.
• All labels indicate total magnification
• Various tissues are best viewed at different magnifications
• Photos on lab exam will be typical, showing tissue at
magnifications at which they are recognizable

Lab exam question example:
1. Name this tissue (entire slide)
– include major category and subtype.
2. Name this special feature (inside circle)
