What else can I help you with?
When impulses from various sources have an additive effect on a neuron the process is called?
When impulses from various sources have an additive effect on a neuron, the process is called summation. This can occur through temporal summation, where multiple impulses from the same source rapidly fire in succession, or spatial summation, where impulses from different sources converge at the same time to reach the neuron's threshold for firing.
Where are taste impulses from?
Taste impulses are from a region in the brain called the primary gustatory cortex. The sense of taste is ultimately felt on various areas of the tongue where taste buds are present.
What major mineral is required for transmission of nerve impulses?
neuro transmitter is essential for the transmission of nerve impulses in nerve fibres.it is a chemical which is present in the axon terminal bulb(ending of a neuron).
What carries cardiac impulses to the myocardium?
Cardiac impulses are carried to the myocardium via specialized muscle cells called Purkinje fibers. These fibers are part of the cardiac conduction system and help to transmit electrical signals rapidly and efficiently throughout the heart muscle.
Where does the interneuron carry impulses?
where does the unterneuron carry impulses
Are impulses conducted rapidly if neurotransmitters are present?
Myelin
Nerve impulses are conducted along an axon without decrement This means the action potentials are conducted without?
decreasing amplitude
Which is a very serious type of heart block in which no impulses are conducted to the ventricles?
third degree heart block
What is the present tense of conduct?
Conducted
Why does increasing the axon diameter also increase the speed of impulse conduction?
Larger diameter axons conduct impulses more rapidly than axons with a smaller diameter. Larger axons tend to be myelinated and conduct impulses rapidly. Myelin is a substance rich in lipid that forms an electrical insulation layer around the axon. This insulating myelin sheath allows impulses to be transmitted more rapidly then small diameter axons that are nonmyelinated.

At what speed are nerve impulses conducted in myelinated and unmyelinated neurons?
In thick well insulated (myelinated) neurones the impulse can travel in excess of 100m/s. In unmyelinated neurones the impulse can be conducted at less than 1m/s

What fibers are the most rapid nerve impulses conducted on?
These are nerves in animals. They include central and peripheral; peripheral include somatic and autonomic.
What is a difference between optic nerve and auditory nerve?
Optic nerve is found in the eye which sends the nerve impulses from the eye to the brain. The auditory nerve is present in the ear and sends the nerve impulses from the ear to the brain. They both have the same functions though they're present in different places.
Why electrical impulses are referred to as neural impulses?
Electrical impulses are referred to as neural impulses because a neural impulse cause electrical impulses. Neurons use electrical impulses to send messages.
