Review the knee jerk reflex and explain what part of the reflex would be the “reaction time to

EMG?”

Expert Solution

The knee jerk reflex is also known as the patella jerk and this jerk takes place when the patellar tendon which is located above kneecap is reflex and hence this leads to causing involuntary jerk. The nerve receptors which are present in the tendon sends signals and hence leads to the involuntary movement of the leg. The knee jerk reflex is a way to check any nerve damage as the nerves present in the patellar tendon are connected directly to the spinal cord. The knee jerk reflex uses two nerve cells that are connected to the spinal cord.

The reflex reaction time can be categorized between a scale of 0 to +4. It is the reaction reflex time of +3 which will be the reaction time to the ECG. The +3 reaction time includes hyper-reflex which can be normal but when there is excessive response, it indicates damage to the spinal cord and the nerve attached to the patellar leading to causing the spinal reflex.
