What is the period of time that elapses between the generation of an action potential and the start of muscle tension development in a muscle fiber?

The answer is the latent period. 
The latent period is the period elapsing between the application of a stimulus and the obvious response, such as the contraction of a muscle. The contraction period, or contraction time, is the time it takes the muscle to reach its peak contraction after the latent period. The relaxation period is the time the muscle takes to return to resting tension after reaching its peak contraction.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
