Nyob rau xyoo 1902, Emilio Veratti ua cov lus piav qhia tseeb tshaj plaws, los ntawm lub teeb microscopy, ntawm cov qauv reticular hauv sarcoplasm. Txawm li cas los xij, cov qauv no yuav luag ploj mus rau tus txiv neej txoj kev paub ntau dua 50 xyoo thiab tau rov tshawb pom dua thaum xyoo 1960, tom qab kev taw qhia ntawm electron microscopy.
Sarcoplasmic reticulum nyob qhov twg?
Lub sarcoplasmic reticulum (SR) yog ib daim ntawv ntawm cov nqaij mos endoplasmic reticulum (ER) pom nyob rau hauv pob txha pob txha uas ua haujlwm ua tus tswj hwm ntawm Ca 2 + cia thiab tso homeostasis thaum lub sij hawm thiab tom qab cov leeg nqaij contraction [51].
Vim li cas nws thiaj hu ua sarcoplasmic reticulum?
Lub sarcoplasmic reticulum (SR) yog cov txheej txheem membrane-bound nyob rau hauv cov leeg hlwb uas zoo ib yam li cov endoplasmic reticulum du nyob rau hauv lwm lub hlwb. … Yog li ntawd, nws yog tseem ceeb heev uas calcium ion qib tswj nruj, thiab tuaj yeem tso rau hauv lub cell thaum tsim nyog thiab tom qab ntawd tshem tawm ntawm tes.
Dab tsi yog qhov tshwj xeeb ntawm sarcoplasmic reticulum?
Lub sarcoplasmic reticulum (SR) tsim lub ntsiab ntawm cov calcium hauv lub cev hauv cov leeg nqaij striated thiab ua lub luag haujlwm tseem ceeb hauv kev tswj hwm ntawm excitation-contraction-coupling (ECC) thiab ntawm intracellular. calcium concentrations thaum contraction thiab so.
Pom dab tsi hauv sarcoplasm?
Sarcoplasm yog lub cytoplasm ntawm cov leeg nqaij. Nws yogCov kua dej uas muaj ATP thiab phosphagens, nrog rau cov enzymes thiab nruab nrab thiab cov khoom lag luam molecules koom nrog ntau yam kev cuam tshuam metabolic. Cov hlau ntau tshaj plaws hauv sarcoplasm yog potassium.
