What is the difference between the axon and axonal terminal and synaptic knob?
The axon is a long, slender projection that carries electrical impulses away from the cell body. The axonal terminal, or synaptic knob, is the end of the axon that forms a synapse with another neuron or target cell. The synaptic knob contains neurotransmitter vesicles that are released into the synapse to communicate with the next cell.
Along a neuron the correct pathway for impulse conduction is?
Impulses are conducted along a neuron in one direction, from the dendrites to the cell body, then through the axon and to the axon terminals. This pathway ensures that signals are transmitted efficiently and effectively from one neuron to another or to an effector cell.
Is and axon bulb and an axon hillock the same thing?
axon hillock = where cell body meets the axon axon bulb = end of the axon...lies very close to the dendrites of another neuron so impulses can pass over the synapse. AP Biology student *
What are the function of the nerve fibers?
Arevbranching fibers at the end of the axon that lead the nervous impulse from the axon to the synapse
The axon of each motor neuron has numerous endings are called what?
The tip of a neuron's axon culminates in several endings call terminal buttons. When an action potential is conducted down the axon, this is where it goes.
What does not belong axon terminal synaptic knob bouton axon collateral?
Bouton does not belong as it refers to a swollen region along an axon where synapses are found, while axon terminal, synaptic knob, and axon collateral are all parts of the structure of a neuron.

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!
Neurotransmitters are released from vesicles located in knob-like terminals on the?
end of axons in the synapse.
Along a neuron the correct pathway for impulse conduction is?
Impulses are conducted along a neuron in one direction, from the dendrites to the cell body, then through the axon and to the axon terminals. This pathway ensures that signals are transmitted efficiently and effectively from one neuron to another or to an effector cell.
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 the difference between the terminal button and the axon terminal?
The terminal button, also known as the synaptic knob, is a small structure at the end of an axon that releases neurotransmitters into the synapse during neuronal communication. The axon terminal refers to the broader region at the end of the axon that includes the terminal button and the surrounding structures involved in synaptic transmission. While both terms are often used interchangeably, the axon terminal encompasses the entire end section of the axon, whereas the terminal button specifically refers to the site of neurotransmitter release.
What is the structure at the end of an axon that produces neurotransmitters?
The axon is a single process extending from the axon hillock, sometimes covered by a fatty layer called a myelin sheath that conducts nerve impulses away from the cell body of the neuron.Distal tips of axons are telodendria, each of which terminates in a synaptic knob.
What word that starts with k meaning boss?
it could mean "knob" or "knoblike" depending on the meaning of the word "boss"
What is the meaning of pummel?

What is the meaning of stitch width knob?
The stitch width knob is usually located on the front of a sewing machine to determine the side-to-side motion of the needle as it stitches.
Is and axon bulb and an axon hillock the same thing?
