Synaptic Cleft.
synaptic cleft, where neurotransmitters are released by the synaptic terminal and bind to receptors on the muscle fiber to trigger a muscle contraction.
neurotransmitters
The small space separating pre and post-synaptic neurons is called the synaptic cleft. This cleft allows for the transmission of chemical signals, known as neurotransmitters, from the pre-synaptic neuron to the post-synaptic neuron to occur. The neurotransmitters are released by the pre-synaptic neuron and bind to receptors on the post-synaptic neuron to transmit the signal.
Synaptic cleft .
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.
c) neuromuscular junction, d) synaptic cleft.
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.
The gap between the axon terminal and muscle cell is called the synaptic cleft. It is defined as the small gap, measured in nanometers, between an axon terminal and any of the cell membranes in the immediate vicinity.
Ca2+
Neurotransmitters are broken down in the synaptic cleft by enzymes called monoamine oxidase and catechol-O-methyltransferase, depending on the type of neurotransmitter. These enzymes break down neurotransmitters into metabolites that are either taken back up by the pre-synaptic neuron for recycling or diffused away.
