What Molecules of what substances are stored in synaptic terminals?
Synaptic terminals store neurotransmitter molecules, which are essential for communication between neurons. Common neurotransmitters include acetylcholine, dopamine, serotonin, and glutamate. These molecules are released into the synaptic cleft during synaptic transmission, facilitating the transmission of signals across the synapse. Additionally, some terminals may store neuropeptides, which also play roles in modulating synaptic activity.
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 neurotransmitters are stored in synaptic vesicles?
Synaptic vesicles primarily store neurotransmitters such as acetylcholine, dopamine, serotonin, norepinephrine, and gamma-aminobutyric acid (GABA). These chemical messengers are released into the synaptic cleft during neurotransmission, facilitating communication between neurons. The specific neurotransmitter stored in a vesicle depends on the type of neuron and its function within the nervous system.
Which factors increase synaptic transmission?
Several factors can increase synaptic transmission, including the availability of neurotransmitters, the sensitivity of receptors on the postsynaptic neuron, and the frequency of action potentials in the presynaptic neuron. Enhanced calcium ion influx during action potentials also promotes neurotransmitter release. Additionally, the presence of neuromodulators, such as serotonin or dopamine, can facilitate synaptic strength and efficacy. Improved neuronal health and myelination can further support efficient synaptic communication.
What causes vesicles to move toward membrane of an axon?
Vesicles in an axon move towards the membrane due to the activity of molecular motors such as kinesin and dynein. These motors use ATP to move along microtubules in the cytoskeleton, carrying vesicles to their destination at the axon terminal. This movement is essential for the release of neurotransmitters during synaptic transmission.
Which component has a role in the post synaptic cell during synaptic activity?
Chemically Gated Channels.

Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
The ability of the body's circulatory and respiratory systems to supply fuel and oxygen during sustained physical activity is which component of physical fitness?
Cardiorespiratory endurance
What is the normal sequence of events that occur during synaptic transmission at a motor end plate?
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.

What does a dream about a hairless friendly pet rat mean I would NEVER have a rat for a pet?
All you can really know for certain from a dream is that somewhere you thought of it, or had a memory of it. A dream is simply your brain trying to make sense of random synaptic activity during REM sleep. Your waking thoughts and memories are often shuffled around during this process which is what makes for such buzzer happenings.
Do not around the room during an activity?
Perhaps "Do not MOVE around the room during an activity".
Does RNA polymerase have exonuclease activity during transcription?
No, RNA polymerase does not have exonuclease activity during transcription.
