Transverse tubules. Tubules formed by invaginations of the sarcolemma and flanked by the sarcoplasmic reticulum. They carry action potentials deep into the muscle fiber. T tubules and SR provide tightly linked signals for muscle contraction.
Also known as Oxycodone, PercocetÂ® is in a group of drugs called narcotic pain relievers. Percocet Â® is a combination of an analgesic, colloquially known as a painkiller, an antipyretic, a drug used to lower the bodyâs temperature and a narcotic, a drug used primarily to induce sleep.
PercocetÂ® (oxycodone/APAP) is a prescription pain medication. It contains acetaminophen (also known as TylenolÂ® and often abbreviated as APAP) and oxycodone, an opiate narcotic. Percocet is quite likely to cause constipation due to the narcotic component. Although you may be able to avoid this side effect if you take Percocet for just a few days (or if you only take it now and then), most people who take the drug will develop some degree of constipation.
