Reticular ho okumu. Ka pilina me ka Hawaii reactions

Brainstem reticular ho okumu i ke kahua o ka plexiform, ai iiiaanoaa o neural hale, Aia ma Central māhele (thalami, midbrain a me ka medulla). Neurons e e ia mai, oko a ma ka nui, neurite loa, 'ole. Kaulana lākou anuanu ulana i.

Oihana o ka reticular kahua

Ho okumu ua pili i ka cerebellum, spinalʻaha, cortex i loko o ka cerebral hemispheres, ka limbic (ina na reactions loa nui i loko o ke kino) nenoaiu. Ma ke kahua o ka hei launa pū 'pii (afferent) a iho (efferent) lāʻau ikiʻai wale. Nā lāʻau ikiʻai wale ke kūhōhō, a paa hou mai la neural wahi i puhi ai. Ma keia hihia, ikaika manaʻo pīhoihoi ua hoakaka ia ma ka reticular kahua neurons ma kekahi pae. I ka hopena o ka kekahi ka hoʻokô 'ana i ka hana ana i kekahi mau Oihana o ka Central ko mākou hopohopo nenoaiu. Ka hōʻoiaʻana i ka degere o ka excitation o ka hei kahua ua lawe wauke hemispheres.

Reticular ho okumu maupaʻa wahi hiki o ka hoʻolako 'ole e pono ai ka inhibitory hopena ma spinal Hawaii reactions.

No ka mea manawa mua i ka pilina ma waena o ka spinal reflexes a me stimulation o kekahi mau wahi o ka hei ho okumu i ike I. M. Sechenovym. A laila, i ka American neurophysiologist Megounom me ke kōkua o ke kookoo i pono ia manaʻo ma ka ke kilo o Sechenov.

Penei, ka wā uila stimulation o ka medial kahua ma anesthetized monkeys a me nā pōpoki aia mea he piha cessation o ka neʻe, me he reflex, a me ke kumu no stimulation o Hawaii cii o ka cerebral cortex. Pela a pau wāwahi kŰia e hoʻonāukiukiʻana mai o ka reticular kahua, ua undergone mea ukiuki loa, iʻeluaʻaoʻao ma ka ano.

I ka wa olohelohe ia lakou i ka kīloi paʻewa reticular kahua ciia ma ka periphery, ka lawe 'ana i ka inhibitory ai ka māhele' akomi e pono ai ia ma luna o spinal Hawaii hope.

Ke reticular ho okumu mea hiki ke hana ma kekahi spinal hoʻonaʻauao.

It E e hoʻomaopopo i ka wahi o ka hei kahua, ai e pono ai ia ma luna o Hawaii hope kŰlń ao anteriorly. Penei, ka mea uhi ole wale i ka wahi o ka medulla oblongata, akā, i ka midbrain a me pons.

Upena hoʻonaʻauao ke aloha ia Muscle leo. Ua hamama kūlana R. māpala. Kuekene neurophysiologist hōʻike i ka reticular kahua e loli ai i ka ha awina o ka gamma Hawaii neurons. Lākou mau axons kekahi, ma ka ai-kapaia "intrafuzarnym" Muscle olona, a me ka hana nui i kūlana ma ka rula o ka pae ana o ke kino neʻe, a kulou.

Kekahi mau wahi o ka reticular kahua hiki i ka noho haumāna kahi ole ma ka generalized 'ano o ka cerebral cortex, ka hana' ana me nā mea a pau o kona wahi.

Malama ana i kaʻupena nae ho okumu hope a me ka pā lonoaʻili i kela Nine Inch hehee wale ai hoʻolahaʻia i loko o ke koko ua lawe mai ma humoral aʻe (i carbon dioxide, catecholamines, a pela aku ..). Kēia, ma ka huli, ka poʻea pau i ka hoʻohui 'ana o ka reticular ho okumu i ka rula o kekahi autonomic hana.

It E e hoʻomaopopo i ka hoʻopaʻa 'ana i ka pilina o ka hei kahua a me nā subcortical hale, e ae mai, e hoomaemae ae la i ka waiwai o neurophysiological maomeka o ke' ano o ke kanaka Hawaii (ka eha, Pa, hiamoe, makaʻala, mea naʻau a me ka motivational Hawaii a me na mea e ae). Hoʻohana 'ia ma Medicine haʻawina hōʻike kanaka therapies o CNS pathologies, hoakaka i ka hou e hoʻokokoke i kekahi mau' inikua pilikia.
