What else can I help you with?
The speed of nerve impulse transmission through the axon of a sensory neuron will be quickest in?
I'm guessing; "myelinated nerve fibres" contrary to the much slower "non-myelinated nerve fibres"
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
What are components of a nerve fiber?
A nerve fiber consists of the axon, which transmits nerve impulses, along with protective covering called myelin sheath, Schwann cells that produce myelin, and the endoneurium which surrounds individual nerve fibers.
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.
What influences the speed of a nerve impulse?
the diameter of an axon
What affects the speed of nerve transmission and how is it measured?
The speed of nerve transmission can be affected by factors such as the myelination of the nerve fiber, temperature, and the diameter of the nerve fiber. It is measured using techniques such as nerve conduction studies, where electrodes are placed on the skin to measure the speed of electrical impulses along a nerve.
What two factors affect the speed of nerve signals?
The diameter of the nerve fiber and the presence or absence of a myelin sheath are the two main factors that affect the speed of nerve signals. Larger diameter fibers and a myelin sheath help to increase the speed of nerve signal conduction.
What is required to maintain nerve fiber sheath?
required to maintain nerve fiber sheath
What is the difference between the contour and magnitude of single nerve fiber and nerve trunk?
What is the difference between the contour and magnitude of single nerve fiber and nerve trunk?
The speed of nerve impulse transmission through the axon of a sensory neuron will be quickest in?
I'm guessing; "myelinated nerve fibres" contrary to the much slower "non-myelinated nerve fibres"
COnduction speed of a nerve fiber would be the fastest in a?
Myelinated nerve fiber with a large diameter would have the fastest conduction speed. The myelin sheath allows for saltatory conduction, where the action potential jumps from one node of Ranvier to the next, speeding up conduction. A large diameter also reduces resistance to current flow, further increasing conduction speed.
What is c type of sensory nerve fibers detail?
C fiber sensory nerves have small diameter unmyelenated axons and carry the signals from pain receptors.
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.

What is the site where the muscle fiber and nerve fiber meet called?
Well of course they meet at the neuromuscular junction
What cause a nerve impulse move along the nerve fiber?
Electrical diferences.
What causes a nerve impulse move along the nerve fiber?
Electrical diferences.
