What was the threshold voltage for the frog sciatic nerve?

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.
