What else can I help you with?
The a synaptic knob b motor end plate c neuromuscular junction d synaptic cleft e transverse tubule contains vesicles filled with acetylcholine?
c) neuromuscular junction, d) synaptic cleft.
What is contained inside a synaptic terminal?
A synaptic terminal contains synaptic vesicles filled with neurotransmitters, which are chemical messengers that transmit signals between neurons. It also includes mitochondria for energy production, endoplasmic reticulum for protein synthesis, and other organelles necessary for synaptic function.
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 organelle stores things like neurotransmitters used in nerve cells?
The organelle that stores neurotransmitters used in nerve cells is called the synaptic vesicle. These vesicles hold neurotransmitters like dopamine, serotonin, and acetylcholine before they are released into the synapse to facilitate communication between nerve cells.
What is the structure at the end of an axon that produces neurotransmitters?
The structure at the end of an axon that produces neurotransmitters is called the synaptic terminal or synaptic bulb. It contains vesicles filled with neurotransmitters that are released into the synaptic cleft to communicate with the next neuron or target cell.
What are vesicles filled with?
Serum
Where is the point on axon that a signal can be transmitted?
Signals are transmitted along the axon at the axon terminals or synaptic boutons. These structures are located at the ends of axon branches and contain neurotransmitter-filled vesicles that are released into the synapse to communicate with neighboring cells.
Why is it that the electrical impulse cannot pass from neuron the muscle cell?
There is a space (synapsis) between the neuron and the muscle cell. The electrical impulse can not pass over that. Chemical neurotransmitters are manufactured by neurons in the soma, then stored in little bundles called synaptic vesicles and transferred to the synapses. The release of the neurotransmitter is required for a nerve to simulate the muscle. This is what crosses the space.
What is the function of synaptic knob of axon terminal?
The synaptic knob of the axon terminal is responsible for releasing neurotransmitters into the synaptic cleft to facilitate communication with the receiving neuron or effector cell. This release of neurotransmitters allows for the transmission of signals from one neuron to another, or from a neuron to an effector cell.
How do you use the word vesicles used in a sentence?
A vesicle is a small fluid-filled sac.
What organelle in the cell produces vesicles?
A vesicle is a fluid-filled cavity or an air-filled sac. The processes of budding and endocytosis produce vesicles. These processes involve the folding of the cell membrane over itself to make a pouch.
What separates axon terminals?
The synaptic cleft, a small gap filled with extracellular fluid, separates axon terminals from the postsynaptic membrane of the neighboring neuron. This separation allows for the release of neurotransmitters from the axon terminal to signal the next neuron.
