Tshuaj synapses tso cai rau cov neurons tsim cov hluav taws xob hauv lub hauv paus paj hlwb. Lawv tso cai rau lub paj hlwb txuas rau thiab tswj hwm lwm cov kab ke ntawm lub cev. Ntawm a tshuaj lom neeg , ib tug neuron tso tawm neurotransmitter molecules rau hauv ib qho chaw me me (the synaptic cleft) uas nyob ib sab mus rau lwm lub neuron.

Yog li ntawd, chemical synapse yog dab tsi?

Tshuaj synapses yog kev sib koom tshwj xeeb los ntawm cov xovtooj ntawm lub paj hlwb ua rau ib leeg thiab rau cov tsis yog cov leeg hlwb xws li nqaij lossis qog. A tshuaj lom neeg nruab nrab ntawm lub cev muaj zog neuron thiab cov leeg nqaij hu ua neuromuscular hlws ris.

Ib tug kuj yuav nug, dab tsi yog qhov zoo ntawm cov tshuaj synapses? Tshuaj synapses muaj ob qho tseem ceeb qhov zoo hla cov hluav taws xob hauv kev sib kis ntawm impulses los ntawm presynaptic cell. Thawj yog teeb liab ua kom nrov nrov, uas tshwm sim ntawm cov leeg leeg synapses.

dab tsi yog synapse thiab nws ua dab tsi?

Hauv lub paj hlwb, a synapse yog ib tug qauv uas tso cai rau ib tug neuron (los yog paj hlwb) kom dhau ib tug hluav taws xob los yog tshuaj teeb liab mus rau lwm neuron los yog mus rau lub hom phiaj effector cell.

Cov tshuaj tiv thaiv kab mob sib kis yog dab tsi?

Cov qauv ntawm cov tshuaj synapse raug los hauv peb ntu:

Lub pre-synaptic davhlau ya nyob twg feem ntau yog nyob rau ntawm axon.
Lub synaptic membrane ntawm post-synaptic cell feem ntau yog nyob rau ntawm lub dendrite ntawm cov neuron tom ntej.
Synaptic cleft yog qhov me me nyob hauv nruab nrab ntawm ob daim nyias nyias.
