What else can I help you with?
The minimum stimulus needed to cause a contraction is called the?
The minimum stimulus needed to cause a contraction is called the threshold stimulus. This is the minimal level of stimulation required to activate muscle fibers and initiate a contraction response.
What is the minimal impulse that can initiate a muscle contraction?
Threshold stimulusThe minimal level of stimulation required to cause a fiber to contract is called the THRESHOLD STILULUS.
What are two fibers that cause contraction?
Actin and myosin are two fibers that cause contraction.
Why does meth amphetamine cause wildly sexual stimulation when other times there is none?
Methamphetamine can cause wild sexual stimulation when a person does not have this stimulation on a regular basis because the drug can cause the body to produce more hormones.
Will increasing the number of loops in a solenoid cause the strength of its magnetic field to decrease?
No, increasing the number of loops in a solenoid will actually increase the strength of its magnetic field. This is because more loops increase the amount of current flowing through the coil, which in turn increases the magnetic field produced.
Does nipple stimulation cause a miscarriage?
no
Does sympathetic stimulation cause increase in blood glucose?
Yes, sympathetic stimulation can increase blood glucose levels. During stress or in response to the "fight or flight" response, the sympathetic nervous system activates the adrenal medulla to release catecholamines like epinephrine. These hormones promote glycogenolysis and gluconeogenesis in the liver, leading to an increase in blood glucose levels to provide energy for the body.
What does stretching a myocardial cell cause the cell to do?
Stretching a myocardial cell allows more Ca+2 into the cell and increases the force of contraction (the longer the muscle fiber when it begins to contract, the greater the force of contraction).
What are the effects of electrical stimulation to the sciatic nerve?
Electrical stimulation of the sciatic nerve can lead to various effects, including muscle contraction in the lower limb, pain relief through the activation of pain modulation pathways, and improved blood circulation. It is often used in therapeutic settings to aid in rehabilitation, manage chronic pain, or enhance muscle function. However, excessive stimulation can cause discomfort or muscle fatigue. Overall, the effects depend on the parameters of the stimulation and the individual's specific condition.
Why would thermal stimulation increase an action potential?
By applying a thermal stimulation into the nerve, means you stimulate it. So with a thermal stimulation, you're already made a possibility to increase the Na+ flow faster.Because as heat, Na ions will move faster than room temperature. They move faster, cause the flow move faster, then the stimulate reach the threshold or even more than that.. causes the increased of action potential
Can clits move?
Yes, the clitoris can become engorged and increase in size when aroused. This can cause it to shift or move slightly, allowing for increased stimulation and pleasure during sexual activity.
Which type of contraction is most likely to cause discomfort in q5?
The eccentric muscle contraction is most likely to cause discomfort in q5.
