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.

The spermatids stained increasingly darker than the secondary spermatocyte as a result of the complete condensation of the heterochromatin, which obscured the nucleus under normal light microscopy.
After several divisions they give rise to cysts of secondary spermatogorila that enter meiosis to produce successively primary and secondary spermatocytes.
Rounded spermatids have a nucleus similar in shape and staining properties to that of secondary spermatocytes, but they are smaller (1.
In secondary spermatocytes, heterochromatin is present in peripheral areas of the nucleus, forming occasional projections towards its center.
In recrudescence, there was renewal of spermatogenic cells characterized by spermatogonial divisions and primary and secondary spermatocytes were occasionally present.
Secondary spermatocytes are abundant, a few spermatids may be present; (3) Late recrudescence, secondary spermatocytes and spermatids predominate; no sperm are present; (4) Early spermiogenesis, clusters of metamorphosing spermatids line portions of the lumina of the seminiferous tubules, occasional spermatozoa are seen; (5) Spermiogenesis, borders of seminiferous tubules are lined by rows of metamorphosing spermatids and spermatozoa are abundant.
Males followed a seasonal testicular cycle (Table 1) in which three stages were represented: (1) Regression (non-reproductive) in which the germinal epithelium is exhausted and the predominant cells are Sertoli cells and spermatogonia; (2) Recrudescence (recovery) characterized by renewal of the germinal epithelium for the next period of sperm formation; primary and secondary spermatocytes are the predominant cells; (3) Spermiogenesis (sperm production) in which the seminiferous tubules are lined by clusters of spermatozoa and metamorphosing spermatids; the epididymides are packed with sperm.
