Ayyuka na da tsoka nama daban-daban jinsunan bambanta dan kadan. Kuma tsarin ma.

Ina tsoka nama a cikin jikin mutum?

Muscle nama daban-daban jinsunan zauna wurin daban a jikin dabbobi da mutane. Saboda haka, daga cikin zuciya tsoka, kamar yadda sunan ya nuna, an gina zuciya.

Daga cikin striated kwarangwal tsokoki kafa tsoka nama.

Smooth tsokoki layi da ciki rami, wanda dole ne a rage. Wannan, misali, hanjinsu, mafitsara, mahaifa, ciki, da dai sauransu

tsoka tsarin jinsuna daban dabam. A ta magana a more daki-daki gaba.

Ta yaya tsoka nama?

Ya ƙunshi wani manyan-sized Kwayoyin - tsoka Kwayoyin. Su ma suna kuma kira fiber. Muscle Kwayoyin mallaka Multi-core da yawa mitochondria - wasu gabbansa da alhakin samar da makamashi.

Bugu da ƙari kuma, tsarin da tsoka na mutum tsokoki da dabbobi ya shafi kasancewar wani karamin adadin intercellular abu dauke da collagen, wanda ya bada elasticity tsokoki.

Bari mu dubi tsarin da kuma aiki na da tsoka nama na jinsuna daban daban.

A tsarin da kuma rawar da santsi tsoka nama

Wannan masana'anta ne sarrafawa da autonomic juyayi tsarin. Saboda haka, ba wanda zai iya rage tsoka sane gina daga m masana'anta.

An kafa daga mesenchyme. Yana da wani irin tayi connective nama.

Rage wannan nama ne da yawa kasa aiki da sauri fiye da striated.

Santsi da masana'anta da aka gina na myocytes fusiform siffar da nuna iyakar. A tsawon wadannan Kwayoyin iya zama daga 100 zuwa 500 micrometers, da kuma kauri - na game da 10 micrometers. Kwayoyin na nama ne mononuclear. A tsakiya aka located in tsakiyar myocyte. Bugu da ƙari kuma, da kyau-ɓullo da wasu gabbansa kamar mitochondria da agranular EPS. Har ila yau a cikin m tsoka nama Kwayoyin suna da babban adadin glycogen inclusions, wanda sune reserves na gina jiki.

A kashi cewa samar da rage tsoka nama jinsin, suna myofilaments. Su za a iya gina na biyu contractile sunadaran actin da myosin. Diamita myofilaments cewa kunshi myosin, shi ne 17 nanometers, kuma wadanda wanda aka gina daga actin - 7 nanometers. Akwai kuma matsakaici myofilaments wanda diamita ne 10 nanometers. Wayarwa tsaye myofibrils.

A tsarin da irin wannan tsoka nama kuma ya hada da extracellular matrix na collagen, wanda ya samar da sadarwa a tsakanin mutum myocytes.

Ayyuka na da tsoka nama na wannan irin:

• Sphincter. Shin cewa na m tsoka kyallen takarda shirya a wani madauwari gudãnar da abun ciki na wani sauyin jiki zuwa wani, ko daga wani sashi na jiki zuwa wani.
• Fitarwa. Yana ta'allaka ne da cewa santsi tsokoki taimaka jiki excrete sharar kayayyakin, kazalika da shiga a cikin aiwatar da haihuwa.
• Samar da wani jijiyoyin bugun gini lumen.
• Formation na ligamentous na'ura. Godiya ga shi, dama gabobin, kamar kodan, aka gudanar a wuri.

Yanzu bari mu dubi cikin irin tsoka nama.

Striated

Yana ke kula da da somatic juyayi tsarin. Saboda haka, mutum zai iya sani tsara irin wannan tsoka. Daga cikin striated kwarangwal tsoka nama yana kafa.

Wannan nama kunshi zaruruwa. Waɗannan su ne Kwayoyin wanda da jam'i na tsakiya zubar kusa da jini membrane. Bugu da kari, suna dauke da manyan yawa na glycogen inclusions. Well-ɓullo da wasu gabbansa kamar mitochondria. Su ne kusa da contractile sel da abubuwa. All sauran wasu gabbansa suna located kusa da nuclei da talauci ci gaba.

Tsarin ta hanyar abin da giciye-taguwar masana'anta an rage, ne myofibrils. Su diamita ne tsakanin daya da kuma biyu micrometers. Myofibrils zauna mafi daga cikin cell da kuma sanya shi a cikin hedkwatarsu. Wayarwa tsaye myofibrils. Suna sanya sama na haske da duhu woje, alternating, wanda halitta giciye "Taguwar" masana'anta.

Ayyuka na da tsoka nama na da irin wannan:

• Samar da jiki motsi a cikin sarari.
• Alhakin da motsi na da sassan jiki zumunta da juna.
• Da ikon ya kula da jikinsa ta hali.
• Da hannu a cikin tsari na zazzabi: da rage aiki tsokoki, da hakan da yawan zafin jiki. Lokacin da misãlin striated tsokoki iya fara zuwa mu'ãmalar involuntarily. Wannan bayyana rawar jiki na jiki.
• Ku bauta wa wani m aiki. Wannan Gaskiya ne, na ciki tsokoki, da abin da na tsare da yawa ciki gabobin daga lalacewa.
• Aiki a matsayin mai depot na ruwa da kuma salts.

Cardiac tsoka nama

Wannan masana'anta shi ne irin wannan duka a cikin striated, kuma m. Kazalika da santsi, shi ne kayyade ta autonomic juyayi tsarin. Duk da haka, sun yi ƙunci shi a matsayin rayayye a matsayin striated.

Ya kunshi Kwayoyin kira cardiomyocytes.

Ayyuka na da tsoka nama na da irin wannan:

• Yana daya ne kawai: to a tabbatar da motsi na jini ta cikin jiki.
