 let’s see if I remember anything lol
1. osteoclasts
a. RANK?

2. uhhh not too sure about this one so I’m just gonna take an educated guess, I think since parts of the immune system can activate necrosis that maybe that can be stimulated during the inflammatory process?

3.myotonia 
b. tropomyosin?

1. Yes!
a. Yes
2. You're on the right track- immune cells like phagocytes migrate to the site of inflammation, and different secretions from them can cause necrosis
3. Yes
a. I was looking for titin, but tropomyosin is right too- without it a muscle couldn't relax at all!

A. What is dystrophin?
B. Labelling:

C:
What type of cartilage is this, how do you know, and where is it found?

A. What is dystrophin?
B. Labelling:

C:

A. Dystrophin is a protein found in muscle fibers that links proteins from the sarcomere to the endomysium. This stabilizes the muscle and helps for overall movement during contraction. 
B. 
1. Sweat pore
2. Epidermis
3. Meissner's corpuscle
4. Dermis
5. Eccrine gland
6. Hypodermis
7. Stratum corneum
8. Stratum lucidum
9. Stratum granulosum
10. Stratum spinosum
11. Stratum basale
12. Sebaceous gland
13. Arrector pili
14. Hair follicle
15. Pacinian Corpuscle
C. This is fibrocartilage. There is a fibrous appearance, with a collagen fiber matrix and little amounts of chondrocytes inside. Fibrocartilage is found in the pubic symphysis and the intervertebral discs.
