Do impulses move faster or slower along the nerve at lower temperatures?
Impulses move slower at lower temperatures because temperature affects the speed of nerve conduction by altering the rate of chemical reactions involved in transmitting the impulse. Cold temperatures slow down these chemical reactions, causing nerve impulses to travel more slowly.
Does one's temperature have an effect on his reflexes?
Yes, body temperature can affect the speed of nerve conduction, which in turn can influence reflex response times. Generally, lower temperatures slow down nerve conduction and may result in slower reflexes, while higher temperatures can speed up nerve conduction and reflexes.
Why is there conduction?
The transfer of heat by molecular motion from a source of high temperature to a region of lower temperature, tending toward a result of equalized temperatures.
What is the natural flow of heat?
The natural flow of heat is from a higher temperature to a lower temperature. This process occurs through conduction, convection, or radiation, depending on the medium through which the heat is transferring.
What is a quality determined by the speed of vibration of sound waves?
Pitch is the quality determined by the speed of vibration of sound waves. Faster vibrations result in higher pitch, while slower vibrations result in lower pitch.

Why does conduction velocity decrease when temperature is lowered?
Conduction velocity decreases when temperature is lowered because lower temperatures reduce the kinetic energy of molecules, leading to slower movement of ions across cell membranes. This results in decreased rates of depolarization and repolarization during action potentials. Additionally, the viscosity of the surrounding extracellular fluid can increase at lower temperatures, further impeding the movement of ions. Overall, these factors contribute to a slower conduction velocity in neural and muscular tissues.
Make a sentence using the words thermal conduction?
The thermal conduction of water is much greater than that of wool.
Heat is transferred from your body into an ice cube by?
conduction, as thermal energy flows from higher temperature to lower temperature through direct contact between two objects.
What happens during continuous conduction?
In Saltatory conduction, the signal leaps or hops from node of Ranvier to another. It uses less energy and it faster. In continuous conduction, the nerve is bare of myelin, moves in continuous waves and the signal is slower.
Why does the frog heart have lower heart rate than mammalian heart?
Frog's internal body temperature is lower than that of a mammal lower temperature = slower heart rate
Why is conduction in gases slower than conduction in liquid or solids?
Conduction in gases is slower than in liquids or solids because gases have lower particle density and weaker intermolecular forces, resulting in less efficient energy transfer through collisions. In liquids and solids, particles are closer together, allowing for faster transfer of kinetic energy through direct contact.
What are the two condition necessary for the conduction of heat?
The two necessary conditions for the conduction of heat are a temperature gradient (difference in temperature) and a material that can conduct heat, such as metals or solids. Heat energy flows from areas of higher temperature to areas of lower temperature through the material.
Why is there conduction?
The transfer of heat by molecular motion from a source of high temperature to a region of lower temperature, tending toward a result of equalized temperatures.
What is conduction about?
The transfer of heat by molecular motion from a source of high temperature to a region of lower temperature, tending toward a result of equalized temperatures.
How is energy transferred when object are in contact?
conduction occurs
