An era is a commonly used word for a long period of time. When used in science, for example geology, an era denotes a clearly defined period of time of arbitrary but well-defined length, such as for example the Mesozoic Era from 252 Maâ66 Ma, delimited by a start event and an end event.
As you increase voltage to the muscle describe how it responds to the increased stimulus. As the voltage was increased from threshold to maximum voltage, there was a greater force in the muscle contraction. Once the maximum voltage (2500 mv) was reached, even if there was an increase in voltage, the force of the muscle contraction remained the same.
Another muscle is responsible to close the lower opening of the bladder in order to prevent the expelling of the urine when the first muscle is contracted.You might want to test yourself to see if there is enough urine to cause the contractions.The minimum amount of urine to cause contractions is 400 milliliters.i, i had a question regarding a bladder problem i have. Since mid 2003, iv noticed that i have a strange bladder problem. What happens is that my urine comes really hard suddenly and i need to get up and walk, and then after 2 minuites it is completely gone.
