Interstitial cell is present in the region outside the seminiferous tubule calledinterstitialspaces.Reason : Interstitial cells provide nutrition to the sertoli cells.

Name of cells scattered in connective tissue and lying between seminiferous tubules

Where does spermatogenesis take place and what cells support this process:Group of answer choicesThe seminiferous tubules are the sites of spermatogenesis and contain sertoli cells which support this processThe epididymis is the site of spermatogenesis and contain Leydig cells which support this processSperm are produced in the prostate and are supported by the sertoli cellsSperm are produced in the seminiferous tubules where spermatogonia reside to support this process

All cells of the body live in essentially the same environment called the internal environment of the body, which one of the following fluids makes up the internal environmentSelect one:a. Transcellular fluidb. Intracellular fluidc. Extracellular fluidd. Interstitial fluid

select one or more statement correctly describe how inner cells can be distinguished from outer cells in the pre-implantation mouse embryo Outer cells are sealed via zippering of actin rings, inner cells are not sealed. Hippo signalling is off in the outer cells, but on in the inner cells.Outer cells are pluripotent (= giving rise to any organ of the adult body), inner cells are determined to give rise to extraembryonic tissue only Inner cells have a “contact-free” surface, outside cells are entirely surrounded by neighbour cells.

The boundary between the interior and exterior of all cells is called the plasma
