The transport mechanism for a neurotransmitter across the synaptic cleft is called?
The transport mechanism for a neurotransmitter across the synaptic cleft is called exocytosis. During exocytosis, neurotransmitter-filled vesicles fuse with the presynaptic membrane, releasing the neurotransmitter into the synaptic cleft where it can then bind to receptors on the postsynaptic membrane.
What causes the synaptic delay?
The cause of synaptic delay is attributed mainly to the time needed for the synaptic vesicles to release neurotransmitter into the synaptic cleft. While it can be considered a combination of binding to the presynaptic membrane (which is relatively a transient process) and subsequent exocytosis of the neurotransmitter, the main factor is release. Additionally, it does take a very short period of time for the neurotransmitter to diffuse across the synaptic cleft and bind to to its receptors on the post-synaptic membrane.
The signal to excite a muscle cell must cross the neuromuscular junction by the diffusion of acetylcholine across the?
The signal to excite a muscle cell involves the release of acetylcholine from the motor neuron into the synaptic cleft at the neuromuscular junction. Acetylcholine diffuses across the synaptic cleft and binds to receptors on the muscle cell membrane, leading to depolarization and muscle contraction. This process is crucial for transmitting signals from the nervous system to the muscle for movement.
How do electrical impulses go across synapses?
An electrial nerve impulse travels across a synapse by diffusion. The neurotransmitter substance from the pre-synaptic cleft travels across the synapse via diffusion. This is then received by receptors in the post synaptic cleft
The narrow space between the synaptic terminal and the muscle fiber is the?
synaptic cleft, where neurotransmitters are released by the synaptic terminal and bind to receptors on the muscle fiber to trigger a muscle contraction.

What is the substance released into the synaptic cleft?
Neurotransmitters are the substances released into the synaptic cleft. They are chemical messengers that transmit signals across the synapse from one neuron to another.
What reactions leap across synapses?
Reactions don't leap across synapses but neurotransmitters will diffuse across the synaptic cleft.
What carries electrical signals across the synaptic cleft between an axon and a receiving cell?
if the gap is too small, electric impulses are directly transmited and in case of relatively large gaps, chemical transmitters helpe in transmitting the impulse
The tiny space between the axon terminal and the dendrite of another neuron is called the?
Synaptic Cleft.
How are synapses adapted for diffusion?
Synapses are adapted for diffusion through the presence of neurotransmitter receptors on the postsynaptic membrane, which allow for the binding of neurotransmitters released from the presynaptic neuron. The synaptic cleft, a small gap between the pre- and postsynaptic neurons, ensures that neurotransmitters can diffuse across and bind to receptors efficiently. Additionally, the presence of enzymes in the synaptic cleft helps to degrade neurotransmitters after they have exerted their effects, allowing for precise control of neurotransmission.
What is the space between neurons across which chemical messages pass?
The space between neurons is called the synaptic cleft. It is where neurotransmitters are released by the presynaptic neuron, travel across the cleft, and bind to receptors on the postsynaptic neuron to transmit chemical messages.
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.
The narrow space between the synaptic terminal and the muscle fiber is the?
synaptic cleft, where neurotransmitters are released by the synaptic terminal and bind to receptors on the muscle fiber to trigger a muscle contraction.
