What else can I help you with?
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter.
What is the gap between a neuron and its effector?
The gap between a neuron and its effector is called a synaptic cleft. Neurotransmitters are released from the neuron into this gap and then bind to receptors on the effector cell to transmit the signal.
Axons terminate in a series of fine extensions known as?
Axon terminals, also known as synaptic boutons or end bulbs, are the fine extensions at the end of an axon that transmit signals to other neurons or effector cells. These terminals contain neurotransmitters that are released into the synaptic cleft to communicate with the target cell.
When electrical signal reaches end of nerve fiber a chemical what is secreted?
When the action potential (electrochemical signal) reaches the end of the nerve, calcium channels open, causing synaptic vesicles containing neurotransmitters to bind with the neuronal membrane. When this happens, the neurotransmitters are released into the synaptic cleft (process is called exocytosis). Once in the synaptic cleft, they can bind with postsynaptic neuron or muscle cell receptors.
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.
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from a neuron to an effector cell?
Neurotransmitter.
What is the gap between a neuron and its effector?
The gap between a neuron and its effector is called a synaptic cleft. Neurotransmitters are released from the neuron into this gap and then bind to receptors on the effector cell to transmit the signal.
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from one neuron to an effector cell?
a neurotransmitter such as acetylcholine, or dopamine. Even a neuropeptide.They will cause a receptor gated channel to open post synaptically
The tiny sacs in the synapse are called?
The tiny sacs in the synapse are called synaptic vesicles. These vesicles store neurotransmitters, which are released into the synaptic cleft to facilitate communication between neurons.
What is the function of synaptic knob of axon terminal?
"When a nerve impulse reaches the synaptic knob at the end of an axon, synaptic vesicles release a neurotransmitter that diffuses across the synaptic cleft and binds to specific receptors on the postsyanptic membrane" Above From:Hole's essentials of Human Anatomy & Physiology (tenth edition) page=220, figure9.9 Quick definition of the "Synaptic knob- Tiny enlargement at the end of an axon that secretes a neurotransmitter." Above From: Same book as before (Hole's essentials of Human...) page= 584 (Glossary)
What is accomplished by synaptic transmission?
Synaptic transmission, also called neurotransmission, refers to the process wherein neurotransmitters are released by a neuron to activate the receptors of another neuron. Communication between two nerve cells is accomplished by synaptic transmission.
What is the function of normal synaptic vesicles in neuronal communication?
Normal synaptic vesicles in neuronal communication function to store and release neurotransmitters, which are chemical messengers that transmit signals between neurons. When an action potential reaches the synaptic terminal, the vesicles release neurotransmitters into the synaptic cleft, allowing for communication between neurons.
Axons terminate in a series of fine extensions known as?
Axon terminals, also known as synaptic boutons or end bulbs, are the fine extensions at the end of an axon that transmit signals to other neurons or effector cells. These terminals contain neurotransmitters that are released into the synaptic cleft to communicate with the target cell.

When this happens, the neurotransmitters are released into the synaptic cleft (process is called exocytosis). Once in the synaptic cleft, they can bind with postsynaptic neuron or muscle cell receptors.
What is autocrine communication?
Any form of "crine" communication involves hormones, the basic chemical form of communication (similar to how synaptic communication works), in this cause auto meaning self regulatory or to put it another way, The hormone released alters(communicates with) the functions of the cell that released the hormone in the first place.
What gap is called into which the chemical is released?
A synaptic cleft is the gap into which a chemical is released.
A synaptic knob would be located on a?
A synaptic knob is a tiny bulge at the end of a terminal branch of a presynaptic neuron's axon!
