What was the threshold voltage for the frog sciatic nerve?
Expert Solution & Answer
Summary Introduction
To write:
The threshold voltage required for the frog sciatic nerve.
Introduction:
Anatomy can be defined as a branch of biology that is associated with the study of the organism’s structure and its parts. In anatomy the superficial indicates the structure is closer to the surface of the body or presents more outside than another. Deep is opposite to superficial.
Explanation of Solution
Muscle is a bundle or band of fibrous tissue present in a human or animal body. It can contract and move in preserving the position of body parts. Muscles play a role in the production of force and motion. They are mainly responsible for sustaining and shifting posture, locomotion.
Threshold stimulus:
The threshold stimulus can be defined as the weakest stimulus which could produce an action potential in a neuron.
Sciatic nerve:
It is a major nerve that runs from the inferior end of the spinal cord down to the backside of the thigh. It divides above the knee joint. It is a nerve having the largest diameter in the human body.
The threshold voltage required for the frog sciatic nerve:
The threshold level of stimulation is about 0.1 volts for the frog sciatic nerve.
Conclusion
Hence, the threshold level of stimulation is about 0.1 volts for the frog sciatic nerve.

Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply. Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.arrow_forward
- When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.arrow_forwardWhen taking vitamins and vitamin-mineral supplements, how can one be sure they are getting what they are taking?arrow_forwardHow many milligrams of zinc did you consume on average per day over the 3 days?
