What are sebaceous cysts, and what makes them different from epidermoid cysts or pilar cysts?
What is a common treatment for sebaceous cysts, and what is the procedure?

Sebaceous cysts are generally mobile masses filled with fibrous tissues, fluids, and/or a fatty, keratinous substance resembling cottage cheese. A "true" sebaceous cyst is filled with sebum and originates from sebaceous glands (whereas epidermoid cysts originate in the epidermis and pilar cysts originate from hair follicles, but the term "sebaceous cyst" is used to refer to both epidermoid and pilar cysts.
Most cysts do not require treatment, but if the cyst grows and becomes painful or infected, it can be surgically removed. If the cyst is infected, antibiotics are used before or after the cyst is removed.

This is something I only learned about today (even though I've been studying Integumentary for two years, whoops)

Although I don't entirely remember it, I think it's an extracellular matrix that surrounds the uppermost part of the papillary dermis and extends a few cells upward into the epidermis.

Correct! I would just add
It functions to attach the epidermis securely to the dermis via connective tissue like collagen
Your turn!

Ok:
What is the major function of sarcoplasmic reticulum?

The sarcoplasmic reticulum is a modified endoplasmic reticulum that stores, releases(during contraction), and retrieves(during relaxation) Ca++ ions. It surrounds the myofibrils just under the sarcolemma.
