spermatocyte

 [sper-mat´o-sīt]
the mother cell of a spermatid.
primary spermatocyte the original large diploid cell into which a spermatogonium develops; it can later undergo the first meiotic division into the secondary spermatocyte.
secondary spermatocyte a haploid cell produced by meiotic division of the primary spermatocyte; it can then develop into the spermatid.

sper·ma·to·cyte

(sper'mă-tō-sīt'),
Parent cell of a spermatid, derived by mitotic division from a spermatogonium.
[spermato- + G. kytos, cell]

spermatocyte

/sper·ma·to·cyte/ (sper-mat´o-sīt) a cell developed from a spermatogonium in spermatogenesis.spermatocy´talspermatocyt´ic
primary spermatocyte  a diploid cell that has derived from a spermatogonium and can subsequently begin meiosis and divide into two haploid secondary spermatocytes.
secondary spermatocyte  one of the two haploid cells into which a primary spermatocyte divides, and which in turn gives origin to spermatids.

spermatocyte

(spər-măt′ə-sīt′, spûr′mə-tə-)
n.
A diploid cell that undergoes meiosis to form four spermatids. A primary spermatocyte divides into two secondary spermatocytes, which in turn divide to form the spermatids.

spermatocyte

[spur′mətōsīt′]
Etymology: Gk, sperma + kytos, cell
a male germ cell that arises from a spermatogonium. Each spermatocyte gives rise to two haploid secondary spermatocytes that become spermatids.

sper·ma·to·cyte

(spĕr-mat'ō-sīt)
Parent cell of a spermatid, derived by mitotic division from a spermatogonium.
[spermato- + G. kytos, cell]

spermatocyte

A cell of the seminiferous tubules of the testis that is converted by MEIOSIS into four SPERMATIDS.

spermatocyte

a diploid or haploid stage in male GAMETOGENESIS.

spermatocyte

the mother cell of a spermatid.

primary spermatocyte
daughter cell of a spermatogonium (an incongruous nomenclature in such an intensely masculine context). It undergoes the first meiotic division.
secondary spermatocyte
a cell produced by meiotic division of the primary spermatocyte, and which gives rise to the spermatid.
