Okay, answer! (Click to Show Hidden Text)

Type 1 - fracture breaks across the entire bone along the epiphyseal/growth plate. 
Type 2 - fracture breaks partially across the growth plate but breaks partly upward into the metaphysis
Type 3 - fracture breaks partially across the growth plate but breaks downward toward the epiphysis
Type 4 - fracture passes through epiphysis, metaphysis and growth plate.
Type 5 - fracture damages growth plate but does not displace. Usually b/c of direct compression.

Correct! Your turn!

Questions! I will ask a few here.

1. Why are there no skin cancers that originate from stratum corneum cells?
2. Why does skin wrinkle and what factors accelerate the wrinkling process?
3. What are epidermal derivatives? Provide an example.

Answers (hopefully) (Click to Show Hidden Text)

1. Because corneocytes are dead, and therefore cannot replicate.
2. Because of a lack of elastin. Don't know about acceleration
3. Structures derived from epidermal cells. Example: Hair root?

3 is wrong. Everything else is right!

examples could be smoking, uv exposure or genetics

Epidermal derivatives are accessory organs of the epidermis. Example: eccrine glands

What types of joint(s) are between the wrist bones?

[sciolylover13]

synovial joints... i think?

Edit: I just realized I forgot to hide...

Gliding

Doesn't it depend if you are asking for functional or strucutral classification. Plus synovial joint types are what most people think of like (ball and socket, planar or saddle joints)
