The transverse tubules (t-tubules) of mammalian cardiac ventricular myocytes are invaginations of the surface membrane that occur at the Z line and have both transverse and longitudinal elements. Many of the proteins involved in excitation-contraction coupling appear to be concentrated at the t-tubules.
Genetic Name: Acetaminophen and Oxycodone. Percocet is the brand name for acetaminophen and oxycodone and is a powerful narcotic used to treat moderate to severe pain. The synthetic opioid is one of the most commonly prescribed painkillers. Percocet is available in capsules and tablets. Adults should not take more than 4 grams (4,000 mg) of acetaminophen in a 24-hour period as it can cause liver damage.
The differences between Percocet, generically known as oxycodone, and Vicodin, generically known as hydrocodone, are in their chemical compound, purpose and side effects.
