Be able to explain each function.What are the 3 ways that the integumentary system provides a physical barrier?Be able to explain the bold terms or phrases included in each example of physical protection.What are the 2 ways that the integumentary system provides a chemical barrier?Be able to explain the bold terms included in each example of chemical protection.What are the 2 ways that the integumentary system provides a biological barrier?Be able to explain the bold terms included in each example of biological protection.Explain the ways that the integument can help regulate body temperature.What is evaporative cooling?How do dermal blood vessels react in different temperatures? Why?What is the largest organ in the human body? (Know both names!)What are the 3 layers of skin?Be able to describe each oneKnow the location if given an illustration as shown in Slide 11 of the PowerPoint.Be able to rank the layers from superficial to deep.What type of body tissue makes up the epidermis?What should the cells look like? (HINT: Review the Tissues lecture material!)How many layers does the epidermis have:in thick skin?in thin skin?Where can thick skin be found? What does it lack?Where can thin skin be found?What are the different layers of the epidermis?Know which one is missing in thin skin.Be able to rank them from most superficial to deepest.If given an illustration or photo of the epidermis, you should be able to label the layers.Describe the characteristics for each layer (aka stratum)List the cells that can be found in each layer and any function associated with those cellsIf a disease is described for that layer, know which cell type is involved and the characteristics of that diseaseWhat three pigment molecules determine skin color?Describe each oneKnow how each one is obtained by the skinWhat are the 7 types of abnormal skin color?Be able to describe each oneBe able to match the photo shown in the PowerPoint to each abnormal skin color type.Know the cause of each abnormal skin type.What are 4 kinds of skin markings?Be able to describe each oneBe able to match the photo show in the PowerPoint to each type of skin marking.Know the cause of each type of skin marking.Where is the dermis located?What types of cells can be found in the dermis?What are the 2 layers of the dermis?What type of tissue is each layer made of?What other structures can be found in each layer? Be able to describe each structure.What is the hypodermis?What type of tissue is it made of?What is its function?Be able to differentiate between the epidermis, dermis, and hypodermis if given an illustration or a photo.Explain how skin heals after an injury.ANIMATION ON SLIDE 51How far into the skin must an injury usually occur to cause scarring?What fills the wound first after the injury? Where does this substance come from?What happens after the event mentioned in “b” above? What visible structure would form at this stage in the healing process?Which type of cells get to work under the structure mentioned in part “c” above? What are these cells doing? What do they produce? Why is this important during the healing process?How does scar tissue arise form the events described in part “d”?Why can hair follicles and regular skin cells grow in a scarred region?Be able to describe and identify a hypertrophic type of scar.What do the collagen fibers in the dermis of look like under this type of scar?What can cause this type of scarring?Be able to describe and identify a keloid type of scar.What do the collagen fibers in the dermis of look like under this type of scar?What can cause this type of scarring?What 4 structures are derived from (made from) the epidermis?What are exocrine glands?What are the 2 types of exocrine glands found in skin?What does each one produce?What is another name for a sweat gland?What are the 2 types of sweat gland?How are exocrine glands classified?What are the 3 types of exocrine glands?How does each one secrete its products?Which 2 types of exocrine glands are sweat glands?Which 2 types of exocrine glands are not found in thick skin? Why? [Hint: Check the Notes tab in the PowerPoint.]What is another name for a merocrine gland?Where can merocrine glands be found?What do merocrine glands make?How do merocrine glands secrete their products?How do these products get outside of the body?What are the functions of merocrine glands?Be able to recognize a merocrine gland if given an illustration or photo.What is a common type of skin holocrine gland?
