Ndeipi iyo tsanangudzo  yeanatomy yedu yeganda modhi?

Artery uye Vein Structure Model

Tsigiro yakakosha yekunzwisisa musiyano pakati pe artery uye vein histology. Mune iyi-chidimbu modhi imwe tsinga uye tsinga mbiri dzinomiririrwa zvakadzama. Imwe tsinga yakakamurwa kureba kuratidza mavharuvhu akavharika uye akazaruka; tsinga uye tsinga yekurudyi zvakapatsanurwa kuitira kuti zvidimbu zvakasiyana, senge tunica media, elastic membrane uye tunica adventitia, inogona kuzivikanwa nyore. 20X hupenyu saizi.

Kukura: 25 * 10 * 55cm,         Kurema: 2.7kgs

MC-YA/HB111  Gastroenterological Endoscope Model

3 zvikamu modhi kuratidza Gastroenterological Endoscope yemukati chimiro.

MC-YA/HB131  Mutevedzeri Wemutauro Wevanhu

Inenge 20x hupenyu saizi. Histological maficha erurimi anoratidzwa, anosanganisira kuravira buds, lingual uye mucous glands, uye yakanaka chimiro chemusculature. Imwe yakaparadzana yehupenyu-saizi modhi yemutauro wakasimba - ine palatine uye lingual tonsils uye epiglottis - inosanganisirwa. Yakaiswa pane yakasimba polymer base. 

Kukura: 33 * 23 * 11cm,            Kurema: 2.8kgs

MC-YA/HB133  Mitosis Model

Iyo mitosis ine 8 modhi kuratidza yayo yese yekukamura kosi. Iyo yekutanga modhi inoratidza yakajairika nucleus modhi. Mhando yechipiri neyechitatu inoratidza kuti hakuna homologous chromosomes inoshanduka zvinoreva mitosis. Kubva pamuenzaniso wechina, inotanga kuratidza mitosis kosi. Centromere haisi pandiro yemetaphase inova pre-period ye mitosis, ipapo centromeres inoiswa nguva dzose pametaphase plate inova nguva yepakati ye mitosis. Yechinomwe modhi inoratidza nucleus itsva haisati yasikwa inova nguva yepamberi ye mitosis uye modhi yekupedzisira inoratidza nucleus mbiri itsva dzapera inova nguva yekupedzisira ye mitosis. Iyi ndiyo nzira yose yekuvandudza mitosis.

MC-YA/HB134  Meiosis Model

Iyo meiosis modhi ine 9 mhando. Mhando yekutanga neyechipiri inoratidza kune homologous chromosomes inoshanduka, inova chikamu chekutanga che meiosis. Yechitatu modhi inoratidza machromosome pairing asi haigone kuudza sisi chromatid, inova meiosis joint period. Mumuenzaniso wechina, 4 chromatids inogona kuonekwa mumakromosomes akabatanidzwa, inova nguva yezvikamu zvina zve meiosis. Mumuenzaniso we5, centromeres iri pedyo nemativi maviri emetaphase plate inoreva kuti tetrad iri paplate ye metaphase, iyo iri pakati penguva ye meiosis I. Muchitanhatu chemuenzaniso, centromeres inofamba kuenda kumatanda maviri kubva paplate ye metaphase, iyo inguva yepamberi ye meiosis I. Mumuenzaniso wechinomwe, centromeres plateti inotangira mutsara, iyo centromeres isati yatanga mutsara we metaphase. pre-nguva uye yepakati-nguva ye meiosis II. Mumuenzaniso wechi8, nucleus miviri mitsva haisati yaumbwa, inova nguva yepamberi ye meiosis. Mumuenzaniso we9, nucleus mbiri dzakaumbwa iyo ndiyo nguva yekupedzisira ye meiosis.
