The velocity of nerve conduction is usually assessed by dissecting out a nerve fiber from an animal such as a frog. The nerve is placed in a chamber containing stimulating and recording electrodes. The responses of the nerve can be monitored using an oscilloscope. More detail on this procedure can be found in the related link.
What else can I help you with?
Which of the following types of nerve fiber possesses the fastest speed of impulse propagation?
Myelinated A fibers have the fastest speed of impulse propagation among nerve fibers.
What cause a nerve impulse move along the nerve fiber?
Electrical diferences.
What causes a nerve impulse move along the nerve fiber?
Electrical diferences.
What is the difference in transmission between myelinated and unmyelinated fibers?
Impulse transmission on an unmyelinated nerve fiber is much slower than the impulse transmission on a myelinated nerve fiber.
Which of the following does not factor into the rate of impulse propagation?
One factor that does not influence the rate of impulse propagation is the size of the neuron. The rate of impulse propagation is determined mainly by the myelination of the axon, the presence of nodes of Ranvier, and the diameter of the axon.
What are mircroscopic fiber that carries the nervous impulse along a nerve cell?
axon
Would conduction speed of a nerve fiber be the fastest in a large or small myelinated fiber?
The conduction speed of a nerve fiber is fastest in large myelinated fibers. This is because myelin acts as an insulator, allowing for faster propagation of the action potential by saltatory conduction in large fibers compared to small unmyelinated fibers.
What is impulse propagation?
Impulse propagation refers to the transmission of information or signals along a biological or artificial network, such as nerve cells in the human body or electronic circuits. In the context of nerve cells, it typically involves the propagation of action potentials along the axon of a neuron to transmit electrical signals. Impulse propagation plays a crucial role in communication and coordination within biological systems as well as in the functioning of electronic devices.
What is quicker a nerve impulse or a hormone?
nerve impulse
Nerve fiber arising from a slight elevation of the cell body that conducts an impulse away from the cell body?
axon
What affects nerve impulse speed?
Nerve impulse speed is affected by the diameter of the nerve fiber (larger fibers conduct faster), the presence of myelin sheath (myelinated fibers conduct faster), and temperature (warmer temperatures enhance conduction speed). Additionally, the refractory period of the neuron and the strength of the stimulus can also influence nerve impulse speed.
Mechanism of nerve conduction?
Nerve conduction involves the transmission of electrical impulses along the length of a nerve fiber. When a nerve is stimulated, sodium ions rush into the nerve cell, causing a change in electrical charge. This creates an action potential that travels down the nerve fiber, activating adjacent areas and allowing the signal to be transmitted. Once the impulse reaches its destination, neurotransmitters are released to stimulate the next nerve cell or muscle fiber.
