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.
Percocet contains five milligrams of oxycodone, which is all released when the pill is taken. Percocet also contains acetaminophen (the drug in Tylenol), which makes people sick if they take a lot of it. OxyContin doesnât contain acetaminophen. It is pure oxycodone in amounts much larger than in Percocet.
