The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine
The signal to excite a muscle cell must cross the neuromuscular junction by the diffusion of acetylcholine across the?
synaptic cleft
What part of nerve cell is adjacent to neuromuscular junction?
The axon terminal of a nerve cell is adjacent to the neuromuscular junction. The axon terminal releases neurotransmitters that transmit signals across the synapse to the muscle fiber. This signal triggers muscle contraction.
Neuromuscular junction is also known as the what?
The NMJ is the region where the efferent motor nerves connect with muscle tissue. When a signal is sent from the brain, down the spinal cord, to the nerve, neurotransmitters are released into the synaptic cleft (primary acetylcholine), which cause the muscle to contract.
What is neural signal?
It is the explanation of signal transfer along a nerve cell or neuron.

Neural transmission across a mammalian synaptic gap is accomplished by?
impulses causing the release of a chemical signal and its diffusion across the synapse.

How does botulisma serious form of food poisoningcause muscle paralysis?
Botulinum toxin (aka. Botox, produced by the bacteria Clostridium Botulinum) causes paralysis by disrupting exocytosis of acetylcholine into the neuromuscular junction. When a nerve impulse reaches the neuromuscular junction, it normally triggers vesicles storing acetylcholine to fuse with the axonal membrane, releasing its contents into the junction where acetylcholine can trigger an action potential in the muscle fibre. Failure of the vesicle to fuse and release its contents into the junction deprives the muscle of any kind of signal that would cause contraction, thereby paralyzing it.
What is the Black widow spider venoms effect at neuromuscular junction?
A black widow spider venom acts on Ach which is a neurotransmitter and stops the normal cascade which then causes the muscles to not get the signal to move, causing paralysis and potential death
Can neurotransmitters cross the synaptic cleft?
Yes, neurotransmitters diffuse across the synaptic cleft to transmit a neural signal; the actual neural impulse(spike) occurs when the neuron fires in response to a sufficiency of signals received.
What is neural signal?
It is the explanation of signal transfer along a nerve cell or neuron.
What are the two elements needed for neural communication to happen?
Neural communication requires an electrical signal to travel down the axon of a neuron, which is generated by changes in ion concentrations across the cell membrane. At the synapse, neurotransmitters are released from the presynaptic neuron and received by receptors on the postsynaptic neuron to transmit the signal.
What component develops the output signal in a common emitter amplifier?
The voltage drop across the emitter-collector junction develops the output signal with the help of a resistor or two in series. The output is 'seen' at the collector.
What creates the electrical signal in your heart?
neural impulses from the brain
