What is synaptic connection in human?
It's the connection point between pieces of the nerves. It's where 2 nerves pass on a signal.
What is the association of axons with nerves?
Axons conduct the nerve impulses, or action potentials, to the axon terminals and the synaptic cleft.
What is the space between the nerve and muscle called?
The synapse is the name of the space between two nerves.
What is synaptic potential?
synaptic potential
The are sack-like structures found inside the synaptic knob containing chemicals?
synaptic vesicles
What is the small space separating pre and post-synaptic neurons?
synaptic cleft (also known as "synaptic gap")
What causes calcium ions to enter the synaptic bulb?
The nerve signal arrives at a synaptic knob and causes calcium channels to open. This allows the calcium ions to enter the synaptic knob. Calcium ions entry into the synaptic knob triggers exocytosis of synaptic vesicles, which release acetylcholine into the synaptic cleft.
Is synaptic transmission always from pre to post synaptic?
Yes
What are synaptic gaps?
Synaptic gaps are the spaces between neurons.
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.
Synaptic signaling between adjacent neurons is like hormone signaling in which way?
Nerves communicate at specialized cell junctions known as synapses. In response to some stimuli, in many cases an action potential, the pre-synaptic nerve releases signal molecules into the space between the two cells (the synaptic cleft). The signaling molecule is then bound by a receptor on the post-synaptic neuron. In this fashion "instructions" can be communicated between neurons. Generally binding of the messenger signal leads to the opening of an ion channel in the post-synaptic nerve causing that nerve to either become more or less excited. In the case of more excited the post-synaptic neuron will approach being able to fire its own action potential if it is excited enough.
How is synaptic potential associated with pain?
What is the role of synaptic potentials in the perception of pain? What kind of reaction might you expect if synaptic potentials were removed?
