What else can I help you with?
Three factors that influence the rapidity and effectiveness of reflex arcs which of these factors increases the excitatory level of the spinal cord?
mental distraction, effect of simultaneous muscle activity in another body area, and fatigue
What reflex regulates the activity of smooth muscle?
autonomic reflex
Can someone live with no brainstem?
No, we need the brainstem to breath, and for reflex activity such as the gag reflex and the cough reflex that protect the air way.
Is the Patellar reflex inhibited or enhanced by voluntary muscle activity in the quadriceps?
The patellar reflex is enhanced by voluntary muscle activity in the quadriceps. When you contract your quadriceps, it stretches the patellar tendon, causing a stronger reflex response when the knee is tapped.
What was the effect of mental distraction on your ability to produce the patellar reflex?
It increases the reflex action."Because of the complexity of the nervous system and the large number of stimuli constantly impinging on the body, the activity of neural networks in one part of the nervous system often modifies another. This is the case for reflexes, such as the knee jerk.The magnitude of the knee jerk is greater when the contractile tone in the extensor muscle is higher. Conditions that increase muscle tone, such as mental excitement increase the extent of the knee jerk.A decrease in mental excitement (sleep, a restful state, etc.) is associated with a decrease in the reflex. The strength of the "tap" required to evoke the reflex is higher after physical or mental work. The knee jerk may be reinforced by a second stimulus, such as a loud noise when the noise is appropriately timed with respect to the tapping of the tendon."http://www.the-aps.org/education/lot/pdfs/neurnetworks03.pdf
How did the response time for the learned activity performed in the laboratory compare to that for the simple patellar reflex?
The learned activity's response time changed while the simple patellar reflex stayed the same.
Why would you have no abdominal reflexes?
An abdominal reflex is a polysynaptic reflex (as being superficial reflex) that is stimulated by the stroking of the abdomen around umbilicus. If thereÕs no abdominal reflex, it is the effect of a physiological absence due to tolerance or obesity.
Blue top tube is drawn for?
protein s activity and reflex to antigen
Do hiccups effect pulse rate?
No, they're just an acid reflex and don't have any effect on your pulse.
How did the response time for the learned activity?
The learned activity's response time changed while the simple patellar reflex stayed the same.
Why does mental distraction increase your ability to produce the patella reflex?
Mental distraction can heighten the patella reflex by reducing conscious control and inhibiting the brain's ability to override automatic responses. When the mind is occupied, the body may respond more quickly to stimuli, allowing the reflex to occur with less interference from higher cognitive functions. This leads to a more pronounced and immediate activation of the spinal reflex arc responsible for the patella response.
When the subject was concentring on an arithmetic problem did the change noted in the patellar reflex indicate that brain activity is necessary for the patellar reflex or only that it may modify it?
It may modify it.
