The function of the transverse tubule of the skeletal muscle is to?
The function of the transverse tubule (T-tubule) is to transmit the action potential to the sarcoplasmic reticulum. This signal is relayed through the cisternae and to the sarcoplasmic reticulum which releases Ca++. Myosin heads contain ATP and provide energy to form and release crossbridges with the actin filaments. Impulses from the muscle spindles are conducted by groups I and II sensory fibers.
