Which type of axon will velocity of action potential conduction be the fastest?
Myelinated axons with the largest diameter
Which type of tissue regenerates the best?
The Epithelial Tissue.
What type of element has a high boiling point and is a good electrical conduction?
metals
What type of particles flow between objects when they are charged by friction or conduction?
Electrons.
What type of heat transfer will occur between the heated water in a heated pool and yourself?
conduction
What type of nervous system conduction occurs in myelinated axons?
Saltatory Conduction
Multiple sclerosis impairs which type of impulse propagation?
Saltatory conduction uses myelinated sheaths around the axon to aide in the efficiency that an action potential passes down the nerve's axon by jumping between nodes of ranvier. The word saltatory is taken from the french word "saltare" meaning leap. Saltatory conduction saves time and improves energy efficiency in the nervous system. In some neurological disorders such as Multiple Sclerosis, demyelination of axons occur, resulting in a block of conduction of the action potential.
When current leaps across an insulating myelin sheath from node to node the type of impulse conduction is called what?
Saltatory Conduction
What type of conduction takes in unmyelinated axon?
continuous
When does saltatory conduction occur?
Saltatory Conduction is a means by which action potentials are transmitted along myelinated nerve fibers. The cytoplasm of an axon is electrically conduction and because myelin inhibits charge leakage through the membrane, depolarization at one node of Ranvier is sufficient to elevate the voltage at a neighboring node to the threshold for action potential initiation. Therefore in myelinated axons, instead of axon propagating as waves but they occur at successive nodes and 'hop' along the axon. This means of travel is much faster than they would otherwise (120 m/sec compared to 35m/sec in unmyelinated nerve fibers). Another advantage of this is that energy is saved as sodium potassium pumps are only required at specific points along the axon. Sean Sinclair
Which type of axon will velocity of action potential conduction be the fastest?
Myelinated axons with the largest diameter
This type of potential is a brief electrical impulse produced by ions crossing the axon membrane?
The type of potential described is an action potential. It is generated by the movement of ions such as sodium and potassium across the axon membrane, leading to a rapid change in voltage that allows for the transmission of signals along the neuron.
What type of conduction takes place in an unmyelinated axons?
Continuous conduction.
Does impulse travel faster along myelinated neuron?
Yes, impulses travel faster in myelinated axon rather than in unmyelinated. It is mostly due to nodes of Ranvier. Instead of travel along the axon, in myelinated axon impulses "jump" from node to node. Also there are two types of myelinated axons: type A and type B. (Type C in unmyelinated axon.) Type A is the fastest among all of them.
What type of energy transfer is the transfer of heat through matter by molecular activity?
Because of molecular vibration the heat transferred through a solid is called CONDUCTION
What type of materials work in conduction?
Conductors allow heat to pass. And carries the process of conduction.
Is friction a type of thermal conduction?
Yes
