What is the difference between the axon and axonal terminal and synaptic knob?
Axon is branch of neuron that conducts impulse , axonal terminal and synaptic knob are same , it is bulb like and makes a synapse .
Along a neuron the correct pathway for impulse conduction is?
It is heat transfer by the collision of atoms within our atmosphere.
Are axons bidirectional or are they one-way?
The axon needs proteins that are generated in the soma, to aid the synaptic knob or even serve as ion channels, and the proteins travel distally to get there. Other substances need to be disposed of or recycled, and they travel back to the soma, proximally. Therefore materials travel down and up the axon which makes it bidirectional.
What region of the cell secretes neurotransmitters?
an axon terminal
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 does not belong axon terminal synaptic knob bouton axon collateral?
axon collateral
What is the difference between the axon and axonal terminal and synaptic knob?
Axon is branch of neuron that conducts impulse , axonal terminal and synaptic knob are same , it is bulb like and makes a synapse .
Neurotransmitters are released from vesicles located in knob-like terminals on the?
Axon
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!
Along a neuron the correct pathway for impulse conduction is?
It is heat transfer by the collision of atoms within our atmosphere.
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 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)
Part of neuron that sends message through the neuron?
The dendrites are the "input" portion of the neuron, collecting signals from other neurons. However, the axon is the "output" portion of the neuron, sending signals to other neurons.
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?
A knob or ball; an object resembling a ball in form, The knob on the hilt of a sword., The knob or protuberant part of a saddlebow., The top (of the head)., A knob forming the finial of a turret or pavilion., To beat soundly, as with the pommel of a sword, or with something knoblike; hence, to beat with the fists.
