The period during which no new action potential can be fired is called the absolute refractory period. [43] [44] [45] At longer times, after some but not all of the ion channels have recovered, the axon can be stimulated to produce another action potential, but with a higher threshold, requiring a much stronger depolarization, e.g., to −30 mV.
A sentence consisting of at least one dependent clause and at least two independent clauses may be called a complex-compound sentence or compound-complex sentence. Sentence 1 is an example of a simple sentence. Sentence 2 is compound because "so" is considered a coordinating conjunction in English, and sentence 3 is complex.
Artistic interpretation of the major elements in chemical synaptic transmission. An electrochemical wave called an action potential travels along the axon of a neuron.When the action potential reaches the presynaptic terminal, it provokes the release of a synaptic vesicle, secreting its quanta of neurotransmitter molecules.
Axon terminals (also called terminal boutons, synaptic boutons, end-feet, or presynaptic terminals) are distal terminations of the branches of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those ...
Latin word order is relatively free. The verb may be found at the beginning, in the middle, or at the end of a sentence; an adjective may precede or follow its noun (vir bonus or bonus vir both mean 'a good man'); [5] and a genitive may precede or follow its noun ('the enemies' camp' can be both hostium castra and castra hostium; the latter is more common). [6]
The verb sum "I am" (or its parts) is an exception to the rule that verbs tend to come at the end of the sentence in Caesar and Cicero. According to one investigation, in Caesar, when the verb is sum, only 10% of main clauses end with the verb. With other verbs, the figure is 90%. [60]
The idea that you cannot end a sentence with a preposition is an idle pedantry that I shall not put UP WITH." Another called back to those rule books, saying, "I'd like to formally request a ...
The potential mood is a mood of probability indicating that, in the opinion of the speaker, the action or occurrence is considered likely. It is used in Finnish , in Japanese , in Sanskrit (where the so-called optative mood can serve equally well as a potential mood), in Northern Wu , [ 10 ] and in the Sami languages .
