What is the relationship between the diameter of axon and conduction velocity?
There is a positive relationship between the diameter of an axon and its conduction velocity. Larger axon diameters result in faster conduction velocities due to decreased resistance to ion flow. This relationship is described by the principle of "the larger the diameter, the faster the conduction."
What is the relationship between size of nerve and conduction velocity?
For unmyelinated nerves there is a relationship between axon diameter and conduction velocity. Larger diameter nerves conduct faster. For myelinated nerves the a larger diameter nerve will conduct faster between the nodes of ranvier where the action potential is propagated. Conduction is said to be saltatoryas it jumps from node to node.
How does myelination affect nerve conduction velocity?
Myelination increases nerve conduction velocity by allowing action potentials to "jump" between nodes of Ranvier along the axon, known as saltatory conduction. This speeds up the transmission of electrical impulses along the neuron.
What is the relationship between nerve size and conduction velocity?
velocity proportional to square root of diameter
What are two properties determine the conduction velocity in a mammalian neuron?
In mammalian neurons, two key properties that determine conduction velocity are the diameter of the axon and the presence or absence of myelin sheath insulation. Larger axon diameter results in faster conduction due to decreased resistance, while myelination allows for saltatory conduction, where the action potential jumps between nodes of Ranvier, increasing speed.
How does myelination effect nerve conduction?
Myelination will speed the nerve conduction velocity considerably. Myelin is found in Schwann cells which encircle a given axon. It acts mainly as an insulator so that depolarization in one cell does not set off depolarizations in adjoining cells. When a neural membrane is depolarized, local currents are set up between positive and negative ions causing membrane conduction. In myelinated fibers, the local currents go from one internode (or node of Ranvier) in between two Schwann cells to the next internode. Thus we have "salutatory conduction" where a neural impulse actually jumps from one internode to the next without being conducted down the entire cell membrane.
Myelination in the brain serves to?
Myelination in the brain serves to increase the conduction speed of nerve impulses and improve overall communication between different parts of the brain. It also helps to protect and insulate nerve fibers, providing structural support and maintaining the integrity of the neural network.
Is the relationship between velocity and height a linear one on an incline?
No, the relationship between velocity and height on an incline is not linear. Velocity is influenced by factors like acceleration due to gravity and friction, making it a non-linear relationship.
What is relationship between velocity and acceleration?
sorry '=
What is the relationship between starting length and initial velocity of shortening?
The relationship between starting length and initial velocity of shortening is typically an inverse relationship. This means that as the starting length increases, the initial velocity of shortening decreases. This relationship is governed by the length-tension relationship of muscle fibers.
What is the relationship between velocity and acceleratioñ?
Acceleration is the rate at which velocity changes and the direction of the change.
What Best describes the relationship between the velocity and pressure of a fluid?
The relationship between velocity and pressure in a fluid is described by Bernoulli's principle, which states that when the velocity of a fluid increases, the pressure decreases and vice versa. This relationship is based on the conservation of energy in a flow system.
