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."
Slowest point of trajectory?
The slowest point of a projectile's trajectory is at the peak of its curve, where its vertical velocity momentarily reaches zero before changing direction and accelerating back downwards due to the force of gravity.
What is the slowest stream velocity needed to maintain 001 cm particles downstream?
To prevent particles of 0.01 cm from settling downstream, a minimum stream velocity of 0.02 m/s is required, based on Stokes' law calculations for settling velocity.
What is nerve conduction velocity test?
A nerve conduction velocity test is a medical procedure used to assess how quickly electrical impulses travel through nerves. It helps diagnose conditions that affect the nervous system, such as nerve damage, neuropathy, and carpal tunnel syndrome, by measuring the speed of nerve signals. The test involves placing electrodes on the skin to stimulate the nerve and recording the response to determine the speed of conduction.
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.
Put the following nerve types in order from the slowest conduction velocity to the fastest?
The nerve types in order from slowest conduction velocity to fastest are: C fibers (slow pain and temperature) B fibers (preganglionic autonomic) Aδ fibers (fast pain and temperature) Aβ fibers (touch and pressure) Aα fibers (motor neurons)
The velocity of blood is slowest in the?
The velocity of blood is slowest in the capillaries. This allows for maximum exchange of nutrients, gases, and wastes between the blood and the surrounding tissues.
Who invented the nerve conduction velocity test?

What are the factors which affect the nerve conduction velocity?
The factors affecting nerve conduction velocity are as follows:(i) Axon diameter:An axon with a larger diameter conducts faster. In an unmyelinated fiber, the speed of propagation is directly proportional to the square root of the fiber diameter (D), i.e.,Conduction velocity a D(ii) Myelination and saltatory conduction:Myelination speeds up conduction. Thus, the action potential travels electrotonically along the long myelinated segments, and fresh action potentials are generated only at the nodes. This is called saltatory conduction. In a myelinated neuron, the conduction velocity is directly proportional to the fiber diameter (D).(iii) Temperature:A decrease in temperature slows down conduction velocity, (iv) Resting membrane potential. Effect of RMP changes on conduction velocity is quite variable. Usually, any change in the RMP in either direction (hyper polarization or depolarization) slows down the conduction velocity.
Earth spins on an axis but which part of earth spins the slowest?
The Earth's rotation

What is the relationship between nerve size and conduction velocity?
velocity proportional to square root of diameter
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.
Where would the velocity of flow be the slowest in the vascular system if you had a wound in the arm and neck?

What features of nerves improve impulse conduction velocity?

Is the velocity of a nerve impulse greater than electrical conduction's?
yes
