10 Questions2 MinutesCreated by LearningExplorer372

Each of the following statements concerning the spermatogenetic stage of proliferation is true, EXCEPT

Stem cells divide to give rise to two daughter cells: one remains as a stem cell, the other is committed spermatogonium

Stem cells undergo meiotic divisions

Committed spermatogonia undergo several successive divisions to increase their number;

The daughter cells of committed spermatogonium remain connected by cytoplasmic bridges

The following transformations of the spermatid take place in spermiogenesis (stage of formation), EXCEPT

The nucleus becomes decondensed

Mitochondria form the helical sheath round the axonemal complex

The distal centriole initiates formation of the axonemal complex, the proximal centriole remains near the nucleus

Each of the following statements concerning the testicular myoid cells is true, EXCEPT:

Their cytoplasm is rich in myofilaments;

Are surrounded by the basal laminae

Are not capable of collagen synthesis

Are involved in selective transport into and out of the seminiferous tubules.

Each of the following statements concerning the testicular Sertoli cells is true, EXCEPT:

Their basal portions rest on the basal lamina

Their apical portions have processes extending into the tubule lumen

Possess centrioles and are capable of division

Their plasma membranes have receptors for FSH and testosterone

Each of the following statements concerning the testicular Sertoli cell functions is true, EXCEPT:

Support spermatogenic cells

Provide the exchange of substances between spermatogenic cells and blood

Eliminate residual bodies and abnormal sperms

Provide peristaltic contractions of the seminiferous tubules

Each of the following statements concerning the compartmentalization of the seminiferous tubules is true, EXCEPT

Sertoli-Sertoli tight junctions establish basal and luminal compartments

Spermatogonia are in the basal compartment

Meiosis and spermiogenesis occur in the basal compartment

Primary spermatocytes pass from the basal compartment to the lumenal one due to the formation of a new transitional compartment

Each of the following statements concerning the testicular Leydig cells is true, EXCEPT

Are parts of the seminiferous epithelium;

Their cytoplasm is rich in sER, Golgi complex, vesicular mitochondria, and lipid droplets

Produce androgens, mainly testosterone

Their plasma membranes possess receptors for LH and estrogens

Each of the following statements concerning the hormonal regulation of the testis is true, EXCEPT:

FSH effects on the Sertoli cells and they produce ABP in testicular fluid

LH effects on the Leydig cells and they secrete testosterone

ABP concentrates testosterone within the tubules to regulate sperm maturation

Inhibin from Sertoli cells provides feedback with LH

Each of the following statements concerning the epididymis is true, EXCEPT

Has the head, body, and tail;

Sperm maturation in it is not androgen-dependent;

Sperms acquire motility passing through it;

Its epithelial cells secrete glycoproteins that are added to the sperm glycocalyx preventing from premature acrosomal reaction

Each of the following statements concerning the prostate gland is true, EXCEPT:

Surrounds the ejaculatory duct;

Its glands are mucosal, submucosal, and peripheral

The glandular epithelium depends on testosterone;

Its alveoli often contain concretions, especially in elderly males.
