Ngawaphi amaphiko anceda iintlanzi ukuba ziqhubele phambili?

Intshayelelo: Ukuqonda iiFizi zeentlanzi

Iintlanzi zeentlanzi zi-appendages eziphuma emzimbeni wentlanzi kwaye zisetyenziselwa ukuhamba kunye nokuzinza emanzini. La maphiko adlala indima ebalulekileyo kubomi beentlanzi, ezinceda ekudadeni, ekuqhubeni nasekugcineni ulungelelwano ngelixa zihamba emanzini. Ubume kunye nobukhulu bamaphiko entlanzi bunokwahluka ngokuxhomekeke kwiintlobo zabo, indawo yokuhlala kunye nendlela yokuphila.

Ukubaluleka kweeFizi zeentlanzi ekuqubheni

Amaphiko entlanzi ayimfuneko xa equbha. Zivumela iintlanzi ukuba zihambe emanzini ngokunika ukuhamba, ukuqhubela phambili kunye nokuzinza. Ngaphandle kwamaphiko, iintlanzi beziya kusokola ukudada ngokufanelekileyo, kwaye amathuba azo okuphila kwindawo yazo yendalo ebeya kuncitshiswa kakhulu. Iintlanzi ezinamaphiko angaphuhliswanga kakuhle zinokukufumanisa kunzima ukubamba ixhoba, ukubaleka amarhamncwa, okanye zifudukele kwiindawo ezintsha zokuhlala.

Isishwankathelo seeNdidi zeeFins

Iintlanzi zineentlobo ezintlanu ezahlukeneyo zamaphiko: amaphiko e-caudal, amaphiko omqolo, amaphiko, amaphiko e-pelvic, kunye ne-pectoral fins. Uhlobo ngalunye lwe-fin lunomsebenzi othile, kwaye ukumila kunye nobukhulu bazo ziyahluka ngokusekelwe kwiintlobo zentlanzi, indlela yokuphila kunye nendawo yokuhlala.

Amanqaku aphezulu eNtshukumo ePhambili

I-Caudal, i-pectoral, kunye ne-anal fins ngamaphiko aphezulu okuhamba phambili. La maphiko anoxanduva lokudala i-thrust kunye nokutyhala intlanzi emanzini. Ngelixa amaphiko e-dorsal nawo anokuba negalelo ekuhambeni phambili, owona msebenzi wabo uphambili kukubonelela ngozinzo kunye nokuthintela intlanzi ekuqengqelekeni.

I-Caudal Fins kunye nendima yabo kwi-Propulsion

I-Caudal fins, ekwaziwa ngokuba ngamaphiko omsila, yenye yezona maphiko zibalulekileyo ekuqhubeni iintlanzi. Zisetyenziselwa ukutyhala amanzi emva kweentlanzi, ziqhubela phambili. Ubume kunye nobukhulu be-caudal fin iyahluka ngokuxhomekeke kwiintlobo zentlanzi, kunye nentlanzi enomsila owenziwe ngefolokhwe, ngelixa ezinye zinomsila ongqukuva okanye otsolo.

Iipectoral Fins kunye neGalelo Lazo kwiNtshukumo ePhambili

Amaphiko ePectoral afumaneka kumacala omabini omzimba wentlanzi kwaye asetyenziselwa ukulawula, ukumisa, kunye nokuhambisa intlanzi emanzini. Zibaluleke kakhulu kwiintlanzi ezidada kufutshane nasezantsi okanye kwiindawo ezinemisinga enamandla apho kufuneka zigcine uzinzo. Amaphiko ePectoral enza ukuphakamisa kunye nokutyhala phambili, evumela intlanzi ukuba idade ngokufanelekileyo.

I-Dorsal Fins: Ngaba ziyanceda iintlanzi ukuba ziqhubele phambili?

Amaphiko eDorsal abekwe phezu komzimba wentlanzi kwaye asetyenziselwa ikakhulu ukuzinza kunye nokulingana. Ngelixa banokunceda iintlanzi ukuba ziqhubele phambili, umsebenzi wazo ophambili kukuthintela intlanzi ukuba ingaqengqeleki. Ezinye iintlanzi, ezinjengookrebe, zinokusebenzisa amaphiko azo ukuze zinciphise ukutsala nokunyuka kwesantya.

Iimpundu: Umba oBalulekileyo wokuHamba phambili

Amaphiko ezimpundu abekwe emazantsi omzimba wentlanzi kwaye asetyenziselwa ukuzinzisa intlanzi njengoko idada. Zikwabonelela ngokuphakamisa kunye nokutyhalela phambili, okunegalelo ekuqhubelekeni ngokubanzi kwentlanzi emanzini.

Indlela Iintlanzi Ezisebenzisa Ngayo Iiphiko Lazo Ukuqhubela Phambili

Iintlanzi zisebenzisa amaphiko azo ukuqhubela phambili ngokuvelisa ukutyhala kunye nokuziqhubela emanzini. La maphiko asebenza kunye ukuze aphakamise, azinze aze alungelelanise indlela, nto leyo evumela ukuba intlanzi idade ngokufanelekileyo. Iintlanzi zisenokuhlengahlengisa i-engile kunye nendawo ezikuyo amaphiko azo ukuze zitshintshe icala okanye isantya.

Imiba echaphazela iNtshukumo yokuPhambili yeeNtlanzi

Ziliqela izinto ezinokuchaphazela isantya sokuya phambili kwentlanzi, kuquka ubungakanani nokumila kwamaphiko ayo, ubushushu bamanzi, ukuxinana kwamanzi nobunzima bomzimba wentlanzi. Iintlanzi ezinzima kakhulu okanye ezingaphumi kakuhle amaphiko zisenokusokola ukudada ngokufanelekileyo, ngelixa iintlanzi ezinomzimba olungeleleneyo kunye namaphiko anamandla zilungele ukuqubha imigama emide.

Ukuqukumbela: Awona Magqibelo aBalaseleyo oKuqubha ngokuLungileyo

I-Caudal, i-pectoral, kunye ne-anal fins zezona zipho zibalaseleyo zokuqubha ngokufanelekileyo. La maphiko asebenza kunye ukuze akwazi ukutyhalela phambili, azinze, aze alathise icala, nto leyo evumela ukuba iintlanzi zikwazi ukudada emanzini. Nangona kunjalo, ubukhulu kunye nokumila kwamaphiko kunokwahluka ngokuxhomekeke kwiintlobo zentlanzi, indawo yokuhlala kunye nendlela yokuphila.

Iingcebiso zokukhetha iiFins zezilwanyana zasemanzini

Xa ukhetha amaphiko kwizilwanyana zasemanzini, kubalulekile ukuqwalasela iintlobo zezilwanyana, ubungakanani kunye nendawo yokuhlala. Umzekelo, iintlanzi eziqubha kufutshane nasezantsi zinokufuna amaphiko amakhulu e-pectoral ukuzinza, ngelixa iintlanzi ezidada emanzini avulekileyo zinokuzuza kumzimba olungelelanisiweyo kunye ne-caudal fin enamandla yokuqhubela phambili. Ukukhetha amaphiko afanelekileyo kunokunceda izilwanyana zasemanzini zidade ngokufanelekileyo nangokukhululeka kwindawo yazo yendalo.
