Assignment:

1. [Cellular/Tissue] Keratinocytes in the hair matrix undergo mitosis; these new cells push older cells more superficially.

2. [Tissue/Gross anatomy] As new cells are born at the hair matrix, the hair shaft is pushed toward the surface. The external hair is completely dead and composed entirely of keratin.

3. [Cellular/Tissue] Laser hair removal destroys cells of the hair matrix and blood vessels of hair papilla so hair cannot grow.

4. [Cellular/Tissue/Gross anatomy] In all types of hair loss (alopecia), cells of the hair matrix do not undergo mitosis (due to genetics, hormones, or trauma).

Draw by hand and upload a drawing of your photo, or digitally illustrate - either is fine!

5. Diagrams should reflect the information of the captions, which are already provided!

a. The only additional things you need to write are labels on your diagrams.

Label all appropriate proteins, organelles, cells, layers, regions, etc. as necessary.

b. Write your captions next to the appropriate part of your illustration.

c. Captions are categorized based on the "level of organization" - please draw your illustrations accordingly.

Molecular: Show the basic structure, location, and function of specific molecules (most likely proteins) within, on, or outside of a cell - you will likely need to show how proteins are made by organelles or how they are transported to different places (e.g., from one cell to another, or into the extracellular matrix).
Cellular: Show the basic structure and function of a cell - what organelles are being used? What structures within or on a cell are playing a role?
Tissue: Show the basic organization and function of a group of cells (and their surrounding interstitial fluid / extracellular matrix/lumen).
Gross anatomy: Show the body region in question - whatever you would be able to see without the aid of a microscope.
