The tiny knob at the end of each axon is called a synaptic terminal or axon terminal. These terminals are responsible for releasing neurotransmitters into the synaptic cleft, allowing for communication between neurons. They play a crucial role in transmitting signals across synapses and influencing the activity of other neurons or target cells.
What else can I help you with?
What is the tiny space between each axon tip and the next dendrite or muscle called?
The tiny space between each axon tip and the next dendrite or muscle is called a synapse. At the synapse, electrical signals from the axon are transmitted to the dendrite or muscle through the release of chemical messengers called neurotransmitters.
What are tiny puches or sacs in the axon terminals?
The tiny pouches or sacs in the axon terminals are called synaptic vesicles. These vesicles store neurotransmitters, which are chemical messengers that transmit signals between neurons at synapses. When an action potential reaches the axon terminal, the vesicles fuse with the presynaptic membrane and release their contents into the synaptic cleft, facilitating communication between neurons.
What are the tiny branches at the end of a motor neurone called?
The tiny branches at the end of a motor neuron are called axon terminals or synaptic terminals. They are responsible for transmitting signals to target cells, such as muscle cells or other neurons, through the release of neurotransmitters at synaptic connections.
Where is the synaptic gap located?
The synaptic gap isn't a region of the brain itself, but a term used to describe the tiny space between an axon terminal and the axon or tissue it is communicating with; so synaptic gaps are spread right throughout both the central and peripheral nervous systems.
Describe parts of the neuron?
The neuron consists of three main parts: the cell body or soma, dendrites, and an axon. The cell body contains the nucleus and other organelles. Dendrites receive incoming signals from other neurons, while the axon carries signals away from the cell body to transmit to other neurons.
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!
What is the tiny space between each axon tip and the next dendrite or muscle called?
The tiny space between each axon tip and the next dendrite or muscle is called a synapse. At the synapse, electrical signals from the axon are transmitted to the dendrite or muscle through the release of chemical messengers called neurotransmitters.
What are tiny puches or sacs in the axon terminals?

When an action potential reaches the axon terminal, the vesicles fuse with the presynaptic membrane and release their contents into the synaptic cleft, facilitating 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 Are tiny sacs in an axon terminal that release chemicals into the synapse?
The tiny sacs in an axon terminal that release chemicals into the synapse are called synaptic vesicles. These vesicles contain neurotransmitters, which are chemical messengers that transmit signals between neurons. When an action potential reaches the axon terminal, the synaptic vesicles fuse with the presynaptic membrane, releasing their contents into the synaptic cleft to facilitate communication with the next neuron.
What is the tiny space that lies between one axon and a dendrite?
Synapse.
The tiny space between the axon terminal and the dendrite of another neuron is called the?
Synaptic Cleft.
What are the tiny branches at the end of a motor neurone called?
The tiny branches at the end of a motor neuron are called axon terminals or synaptic terminals. They are responsible for transmitting signals to target cells, such as muscle cells or other neurons, through the release of neurotransmitters at synaptic connections.
What are the tiny sacs found within the terminal button which release chemicals into the synapse?
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.
When a nerve impulse reaches the end of the axon the tiny sacs that store the neurotransmitters move to the surface and release the neurotranmistters These tiny sacs that store the neurotransmitters?
are called synaptic vesicles. They contain specific neurotransmitters that are released into the synaptic cleft when the nerve impulse reaches the end of the axon. The neurotransmitters then bind to receptors on the neighboring neuron, continuing the signal transmission.
What is the name of the tiny gap the neurotransmitter has to diffuse across to reach the membrane of the postsynaptic neuron?
The tiny gap that the neurotransmitter has to diffuse across to reach the membrane of the postsynaptic neuron is called the synaptic cleft. It separates the axon terminal of the presynaptic neuron from the dendrite of the postsynaptic neuron.
What are men reproductive cells called?
Men's reproductive cells are called, "Spermatazoa" (spurm-uh-tuh-ZOE-uh) A single cell is called a, "Spermatazoon" (spurm-uh-tuh-ZOE-on) For short, both are often called, "Sperm cells". Sperm cells are very, very tiny, needing a microscope to even see them. They each have a long 'tail' called a flagellum used to swim to where they need to go.
