What are hemidesmosomes? Structures that anchor the cytoplasm to the plasma membrane. Cell adhesion molecules that are associated with actin filaments near the plasma membrane. Cell junctions that allow for passage of ions directly between cells. cellular junctions that anchor the epidermis to the papillary layer of the dermis.

How does collenchyma support a tissue? Would it work if the tissue did not have parenchyma also? What happens if the tissue is not turgid (does not have enough water)?
Why does it makes sense that melanocytes are found in the outer layer Because melanocyte cells are too big to be located deeper in the body. Because the outer layer of skin is where all actively functioning skin cells are located. Because the melanocyte function is dependent on other cells found in the outer skin layer. Because all skin cells originate in the outer layer. Because melanocyte activity can be altered in response to the presence of sunlight.
The outer layer of your skin is the epidermis: a keratinized stratified squamous epithelium. The epidermis is made up of 4-5 layers with different types of cells. For the image and diagram below, label each layer of the epidermis and its cells: Layers = A-E, Cells = #1-7 3- 4 5 7 1 V [ Choose ] Spiny cell 2 Stratum granulosum Granular cell| 3 Stratum lucidum Stratum corneum Stratum spinosum Skin Stem cell Dendritic cell (AKA: Langerhans cell) Horny cell 7 Melanocyte Tactile cell (AKA: Merkel cell) A Stratum basale [ Choose ] [ Choose ] [ Choose ] [ Choose ] B.
