Does a neurotransmitter carry ATP across a synapse?
no
How long does neurotransmitter stay in the synapse What is the rate of removal of neurotransmitter Is it an exponential decay?
Neurotransmitter stay for few milliseconds only in the synapse. The rate is difficult to define, but then the decay is most probably exponential decay. The acetylcholine is destroyed by the enzyme acetylcholinestarage. The noradrenaline is taken up back by the neuron, which has secreted it.
What do you call the chemical released by the axon that travels across a synapse and binds on the dendrites of the other neurons or body cells?
The chemical released by the axon that travels across a synapse and binds to dendrites or cells is called a neurotransmitter. Neurotransmitters play a crucial role in transmitting signals between neurons and regulating various physiological processes in the body.
Drugs act at the synapse by?
affecting neurotransmitter release, blocking neurotransmitter reuptake, or binding to neurotransmitter receptors. This alters the signaling between neurons and can have various effects on mood, behavior, and other physiological processes.
Does sweat glands contain cholinergic receptors?
All the post-ganglionic parasympathatic reseptors are cholinergic (muscarinic) . and all the post-ganglionic sympaythatic reseptors are adrenergic . Except for sweat glands , Piloerecter muscles , and a few blood vessels they use sympathatic nerves but a cholinergic resepotrs . -Note that all the pre-ganglionic ( sympathatic and para sympathatic ) reseptors are cholinergic ( Nicotinic ). -Note that the sweat glands on the palms of the hand are adrenergic , but the rest of the sweat glands are cholinergic.
Which neurotransmitter is secreted by a cholinergic fiber?
acetylcholine
What type of synapse uses neurotransmitter?
Chemical Synapse
What is cholinergic and anti cholinergic drugs?
Cholinergic drugs are used for urinary retention, myasthenia gravis, glaucoma. Cholinergic drugs act like the neurotransmitter ACh (acetylcholine). Anti Cholinergic (also called Cholinergic blocking) drugs block the action of the ACh. Anti Cholinergic drugs are used foe pylorospasm & peptic ulcers, bladder overactivity, parkinson's disease
Cholinergic synapses release what neurotransmitter?
acetylcholine (ACh)
What is the role of neurotransmitter at a chemical synapse?
exocytosis
Does a neurotransmitter carry ATP across a synapse?
no
What is the chemical secreted into the gap between neurons at the synapse?
The answer is NEUROTRANSMITTER.
What is the relationship between a synapse and neurotransmitter?
Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. At a chemical synapse, one neuron releases a neurotransmitter into a small space (the synapse) that is adjacent to another neuron.
Describe the innervation of the blood vessel?
Most of the blood vessels are innervated by sympathetic sympathetic adrenergic nerves.It releases norepinephrine which act as a neurotransmitter. The skin and few areas of body have both sympathetic cholinergic and parasympathetic cholinergic nerves which release acetylcholine,which act as a primary neurotransmitter.
What would happen if the re-uptake of a stimulatory neurotransmitter was blocked?
The action of the excitatory neurotransmitter will increase, since its concentration in the synapse will rise.
Which of the following helps carry nerve impulses across the synapse?
neurotransmitter carries the nerve impulses from neuron to neuron across a synapse
How long does neurotransmitter stay in the synapse What is the rate of removal of neurotransmitter Is it an exponential decay?
Neurotransmitter stay for few milliseconds only in the synapse. The rate is difficult to define, but then the decay is most probably exponential decay. The acetylcholine is destroyed by the enzyme acetylcholinestarage. The noradrenaline is taken up back by the neuron, which has secreted it.
