A sensory stimulus can generate a neural impulse, as can repeated or multiple inputs of neural signals from other neurons.
A neural signal is transmitted from one neuron to anotheracross a synapse via chemicals called neurotransmitters, and a neural impulse is transmitted along an axon of a neuron by either an action potential (in an unmyelinated axon) or by saltatory conduction (in a myelinated axon).
What else can I help you with?
What is the nerve impulse from your foot to your leg called?
The nerve impulse from your foot to your leg is called a sensory nerve signal or proprioceptive feedback. It helps transmit information about sensations such as touch, pressure, and position to the brain.
What is the Impulse generator and transmitter in the nervous system?
In the nervous system axons generate and transmit impulses.
Is conducting stimulus strong enough to generate a nerve impulse?
Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.
What is the space through which a nerve impulse passes from one nerve cell to another called?
The space through which a nerve impulse passes from one nerve cell to another is called a synapse. It is a small gap between neurons where neurotransmitters are released to transmit signals between the cells.
What is quicker a nerve impulse or a hormone?
nerve impulse
What transmits a nerve impulse at the highest rate?
Myelinated nerve fibers transmit nerve impulses at the highest rate due to the presence of insulation provided by the myelin sheath. This insulation helps the nerve impulse jump quickly from one node of Ranvier to the next, allowing for rapid transmission.
How does a nerve pass along messages?
Nerves transmit messages through electrical impulses known as action potentials. When a nerve is stimulated, ion channels in its membrane open, allowing sodium ions to flow in, which depolarizes the membrane. This change in voltage triggers adjacent ion channels to open, propagating the impulse along the nerve fiber. Once the impulse reaches the end of the nerve, it typically causes the release of neurotransmitters, which transmit the signal to the next nerve or target cell.
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
What is the defference between membrane irritability and membrane conductivity?
Irritablity is the ability to respond to stimuli and convert it to nerve impulses. Conductivity is the ability to transmit that impulse.
What nervous tissue has the ability to respond to the a stimulus and covert it in to a nerve impulse?
Neurons are the type of nervous tissue that can respond to stimuli and convert them into nerve impulses. They are specialized cells that transmit information throughout the body by generating and conducting electrical signals. Neurons have various structures, including dendrites, which receive stimuli, and axons, which propagate the nerve impulse to other neurons, muscles, or glands. This ability to transmit signals is fundamental to the functioning of the nervous system.
A nerve impulse is carried across a synapse by?
neurotransmitters, which are chemical messengers that transmit signals between neurons. When a nerve impulse reaches the end of a neuron, it triggers the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the neighboring neuron, initiating a new nerve impulse to continue the signal transmission.
How does a nerve impulse follow all or nothing principle?
How does a nerve impulse follow the all-or-nothing principle???
