0:00:00.750,0:00:04.480
Axırıncı vidyodan bilirk ki,[br]əzələ hüceyrəsi içərisində

0:00:04.480,0:00:09.040
yüksək kalsiyum konsantrasiyası olsa,[br]bu kalsiyum iyonu gedib troponin zülalına

0:00:09.040,0:00:13.500
bağlanacaq, bununla onun forması[br]elə dəyişəcək ki,

0:00:13.500,0:00:17.140
tropomiyozin ortalıqdan çəkiləcək

0:00:17.140,0:00:20.580
və beləliklə miyozinin başı[br]aktin sapları üzərində

0:00:20.580,0:00:23.310
sürünəbiləcək və bununla da əslində

0:00:23.310,0:00:24.950
əzələ büzülməsi baş verəcək.

0:00:24.950,0:00:29.140
Deməli yuxarı kalsiyum konsantrasiyası,[br]ya da kalsiyum iyon konsantrasiyası,

0:00:29.140,0:00:30.850
əzələ büzülməsi deməkdir.

0:00:30.850,0:00:35.560
Aşağı kalsiyum iyon konsantrasiyası, bu[br]troponin zülallarının standard vəziyətinə

0:00:35.560,0:00:39.060
qayıtmasına və tropomiyozinlərin geriyə

0:00:39.060,0:00:42.600
qayıtmasına səbəb olur

0:00:42.600,0:00:44.165
və büzülmə baş vermir.

0:00:53.750,0:00:57.140
Bundan sonraki əsas sual budur ki,[br]əzələ

0:00:57.140,0:00:59.850
yüksək kasiyum konsantrasiyası[br]və büzülməni ya da ki

0:00:59.850,0:01:03.350
aşağı kalsiyum konsantrasiyası və[br]rahatlamanı necə tənzimliyir? Ya da daha

0:01:03.350,0:01:04.940
yaxşı bir sual, sinir sistemi

0:01:04.940,0:01:05.830
bunu necə edir?

0:01:05.830,0:01:09.490
Sinir sistemi əzələyə büzülməsini,kalsiyum

0:01:09.490,0:01:11.550
konsantrasiyasını yülksəldərək büzülməsini

0:01:11.550,0:01:14.010
ya da aşağı salaraq rahatlamasını necə deyir?

0:01:14.010,0:01:17.900
Bunu başa düşmək üçün[br]neyron vidyosunda

0:01:17.900,0:01:20.790
öyrəndiklərmizi bir az təkrar edək.

0:01:20.790,0:01:24.000
Bir aksonun terminal qovşağını

0:01:24.000,0:01:27.500
burada çəkim.

0:01:27.500,0:01:30.540
Başqa bir sinirin dentrində[br]sinaps eləməkdənsə,

0:01:30.540,0:01:32.890
gedib həqiqi əzələ hüceyrəsi ilə

0:01:32.890,0:01:35.130
sinaps eliyəcək.

0:01:35.130,0:01:37.145
Yəni bu onun əzələ hüceyrə ilə sinapsıdır.

0:01:44.420,0:01:47.170
Bu həqiqi əzələ hüceyrəsi ilə sinapsdır.

0:01:47.170,0:01:50.070
Gəl hər şeyi adlandırım ki [br]qarışdırmıyasan.

0:01:50.070,0:01:51.470
Bu aksondur.

0:01:51.470,0:01:53.470
Bunu aksonun terminal ucu[br]adlandıra bilərik

0:01:57.610,0:01:58.860
Bu sinapsdır.

0:02:05.440,0:02:08.150
Neyron vidyosundan balaca bir [br]terminologiya- bu bölgə

0:02:08.150,0:02:10.210
sinaptik yarıqdır.

0:02:10.210,0:02:13.650
Bu presinaptik neyrondur.

0:02:13.650,0:02:15.430
Bu

0:02:15.430,0:02:16.830
postsinpatik hüceyrədir

0:02:16.830,0:02:19.050
Bu da nöyrondur.

0:02:19.050,0:02:21.090
Və bu da əzələ hüceyrəsinin

0:02:21.090,0:02:30.240
membranıdır.

0:02:30.240,0:02:32.540
Və çox güman ki[br]bundan sonraki video ya da ondan

0:02:32.540,0:02:34.530
sonrakində[br]əzələ hüceyrəsinin anatomiyasını

0:02:34.530,0:02:35.610
göstərəcəm.
