Substance released at axonal endings to stimulate a nervous impulse is?
a neurotransmitter
Which structure contains vesicles with acetylcholine?
Synaptic vesicles in the axon terminals of neurons contain acetylcholine. Acetylcholine is a neurotransmitter that is released from these vesicles into the synaptic cleft to transmit signals to target cells or other neurons.
Where is neurotransmitter stored?
Neurotransmitters are stored in synaptic vesicles located at the terminals of presynaptic neurons. When an action potential reaches the terminal, these vesicles release neurotransmitters into the synaptic cleft to facilitate communication between neurons.
Are neurotransmitters stored within motor neuron endings?
No, neurotransmitters are stored in vesicles within motor neuron endings. When an action potential travels down the neuron, these vesicles release neurotransmitters into the synaptic cleft to transmit signals to target cells.
What chemical is released when the nerve impulses reaches the nerve endings?
When a nerve impulse reaches the nerve endings, neurotransmitters such as acetylcholine, dopamine, serotonin, or norepinephrine are released into the synapse to transmit the signal to the next neuron or target cell. These neurotransmitters bind to receptors on the receiving cell, initiating a response.
What is the neurotransmitter that is released into the synaptic cleft?
The neurotransmitter that is typically released into the synaptic cleft is acetylcholine, although there are many others such as dopamine, serotonin, and glutamate. These neurotransmitters carry signals across the synapse from one neuron to another.
Is acetylcholine the substance released by axonal endings of the somatic efferent fibers and by the parasympathetic nerve fiber endings?
Yes, it does. In contrast, the sympathetic nerves release adrenaline
Select the option that lists the steps of normal nerve function in the correct order?
ACh is produced at the intercellular level and is stored in vesicles at nerve endings. nerve endings release ACh ACh attavhes to the receptor site at the receiving nerve ACh is broken down by AChE to prevent accumulation
How does the botulinum toxin act in humans?
Botulinum toxin latches onto specific proteins in nerve endings and irreversibly destroys them. These proteins control the release of acetylcholine, a neurotransmitter that stimulates muscle cells.
How many wed endings are there?
How many wed endings are there?
When was Alternate Endings created?
Alternate Endings was created in 2004.
What is the upper region of the dermis containing parallel rows of tiny bumps is called?
The upper region of the dermis containing parallel rows of tiny bumps is called the papillary layer of the dermis. It contains blood vessels, nerve endings, and dermal papillae that help anchor the epidermis to the dermis.
