Pou synapses a me kā lākou mau hiʻona

Synapses i hana kūikawā ooieoeiiaeuiuo hui 'ana, a i hoonohonoho ma waena o excitable keena. Ka mea, hoʻolele a hoʻololi i ka likeʻole no lepa. Synapses hou i loko o ka palapala o thickenings ma nā wēlau o nā aʻalolo olona. Me kā lākou kōkua nā aʻalolo impulses hoʻopulapula i ka hoalauna keena. O ka papa kuhikuhi hana o ka synapse mea he intercellular EYI o nā aʻalolo impulses.

Mea Maluna, a he manawa pōkole hōʻikeʻano

E like me ke 'ano o nā lāʻau ikiʻai wale i kahi i hui pūʻia, Nine Inch a me ka pou synapses. Nine e lawelawe ai neaiae EYI i kekahi ala e hiki aku, a amplifies mea, e like me depolarize postsynaptic hyperpolarizes a poepoe. Me ke kōkua o Nine Inch synapses maoli ka plasticity ma ka hōʻikeʻana,ʻo ia hoʻi, he kanaka? Ienoai iaiyoe a me ka mämä holo o ka hoʻonaʻauao. Ka uila EYI kahi waiho synaptic kali hou aku, a me ka neaiae ua lawe mai i loko o nāʻaoʻao. lāʻau ikiʻai wale EYI Ua kuokoa mai ka ona o ka presynapticʻili lahilahi. Eia hou kekahi, pou synapses e hoʻopale i ka haʻahaʻa mahana, e like me kekahi hopena mai o ka hale kūʻai lāʻau lapaʻau. huiʻano synapses i kekahi hiʻona. Ka mea, e ia laua i ka Nine Inch a me ka uila ka hōʻikeʻana.

He aha mea he uila synapse?

Pou synapses - Ua intercellular ho okumu ma i hōʻoiaʻiʻo EYI o ka excitation lāʻau ikiʻai wale. Kēia kaʻina ia lŘlŘ aie i ka helehelena o ka uila pono ma waena o nā oihana elua kapaia presynaptic a me ka postsynaptic. ʻO ko mākou hopohopo nenoaiu o invertebrates mai he nui helu o ka pou synapses, oiai ma ka mammals ka mea, ua kokoke ma laila. Together me ka pou synapses i loa a pau mawaena o na holoholona kiʻekiʻe. Ma mau, ka mea, i loko o ka naʻau, akepaa, nāʻiʻo, e like me ia ma ka epithelium a me ka glandular'aʻaʻa. Synaptic mauae ma ka pou synapses mea nuiʻololī ma mua o ka Nine Inch. An pono o kēia 'ano o ka synapse o ka mea i waena o ka pre- a me ka postsynaptic membranes like paha i kahi o ka uapo o ke kumuʻiʻo nā lātoma.

Nui uila synapses hana type

Waiwai o ka pou synapses e like penei:

• hookeai hana (nui i oi haʻawina i loko o Nine Inch type synapses);
• maule kumumea 'ole (summation o ka mea i hahai ana ka mea mamuli o kekahi lāʻau ikiʻai wale kokoke ole);
• ike loea EYI o excitation;
• kiʻekiʻe ductility;
• hoolilo i kekahi a me nāʻaoʻaoʻelua.

Hiʻona o ka 'ole

Ka 'ole o ka pou impulse hoʻomaka me ka postsynapticʻili lahilahi. Next mea he haiki synaptic mauae, a he o transverse tubules haku o ke kumuʻiʻo nā lātoma. Ma hope o ka slit kahi presynapticʻili lahilahi. Ma ka waena o ka semicircular synaptic plaque. Oblong synaptic pau ana - i ka hope hehee ai i loko o ka 'ole o ka pila nui synapse. Aie i ke alo o ke kumuʻiʻo nā lātoma kaha ma waena o pre- a me ka postsynaptic keena,'okanikaʻole Ion, a me ka mea uuku nā lātoma e hiki ke neʻe mai kekahi aeea i kekahi. Oia synapse i ka loa haʻahaʻa uila e kū'ē'ē mai. Ma lalo o kēia mau rula, o ka he noi i ka presynaptic postsynaptic keena, a aneane pio.

I Kekahi Mau ooieoeiiaeuiuo waiwai

I ka pou synapses, loaʻa nō i ka helu o ka hanana ooieoeiiaeuiuo hiʻona. Synaptic kali hou aku; o ka aneane, aole. Impulse hele mai i loko o ka presynaptic maʻi, a laila, koke postsynaptic Loaʻaʻia ke kaʻina kānāwai. I ka wā mawaena ma waena o kēia mau hana ua nalowale. Pou synapses i EYI kaʻina hana wale - no excitation. Ma keia ano o ka synapse ua malamaʻeluaʻaoʻao mamua o ka mea i aie ai i na ano o stereometric hoʻokō 'ia' ana ma kekahi ala loa ka maiau. Ke Kula Kaiapuni 'aʻe (pharmacological, thermal, etc.) iʻaneʻane ole ia ma luna o nā synapses o ka pila nui type.

Pehea ka pīhoihoi ma ka pou synapses? Ke kaʻina hana a me ke kapuai

E mālama nei i kahua (PD) - i ka papa kuhikuhi hana i lawe i ka pou synapse. Keʻano papa hana o kēia kaʻina mea i 'ano like me ka PDP ma synapses i loko o nā aʻalolo olona. I ka wā o ka excitation mea hoʻololi i ka hoʻomaka 'ana mua, he reversal o ka uku ole hoʻomaka presynapticʻili lahilahi. E like me ka hopena, he uilaʻikena, i loli ai ka postsynapticʻili lahilahi, keʻano ukiuki o ia a me ke kumu no ia e paha PD. Conduction o excitation i loko o ka pou synapse mea i ka luna 'physiological kaʻina hana e ia lŘlŘ i loko o kekahi mau kahua o ka hoʻonaʻauao. Presynapticʻili lahilahi hanaʻia i ka hou 'ana o ka uila pāpaʻa i ka Nine Inch, i ka noho ma luna o postsynaptic papa hou e holo ana i loko o ka uila maika i.

Kekahi mau mā ma ka pou synapses

I loko nō o ka mea e lawe mai pou synapses he 'ano mea kaʻina hana o ka excitation hoolilo, ka mea, i kekahi nui flaws. A e'āhewa wale i ka stereotype o ko lākou mau hana. I ka manawa kūpono o ka pololei hoolilo i loihi keena pīhoihoi ma laila. Pre- a postsynaptic keena e pili synapses uila type, ka mea e mau i loko o ka hookahi excitation. ke peleki pāʻana i ka helehelena ole i ke Akua. E like me ka hopena o nā mea a pau i ka luna o ia wā i loko o ke keiki lolo mea,ʻaʻole he wahi lihi iki o ka pou synapses, no ka mea i loko o ka makua e loa he mau i loko o ka retina o ka maka, i ka lolo kumu a me ka aa o ke vestibular i hoʻomākaukauʻia.

A like, akā, i loko o ka palapala o ka pathologicalʻano papa hana o ka excitation mea he hopena o ka maʻi a i pili i degeneration o ka axon palena. Nolaila, ke excitation kaʻina "Lele" mai kekahi i kekahi axon, a e alakai i ka waiʻona ma hoopunipuni. No ka laʻana, i ke ano o ka waiʻona ma o ka eha, hoʻowahāwahā i ka ia kāna o kaʻike ākea eha receptors kānāwai no ka mea, o "hops" excitation.
