The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...
A.—Diagram of the primitive urogenital organs, from 'Diagrams to show the development of male and female generative organs from a common type' * w, w. Right and left Wolffian ducts. The observable, visual differences become apparent between male or the female reproductive organs are not seen initially.
The ejaculatory ducts pass through the prostate gland before opening separately into the verumontanum of the prostatic urethra. [2] The vesicles are between 5–10 cm in size, 3–5 cm in diameter, and have a volume of around 13 mL. [3] The vesicles receive blood supply from the vesiculodeferential artery, and also from the inferior vesical artery.
m, m. Right and left Müllerian ducts uniting together and running with the Wolffian ducts in gc, the genital cord: m. Müllerian duct, the upper part of which remains as the hydatid of Morgagni; the lower part, represented by a dotted line descending to the prostatic utricle, constitutes the occasionally existing cornu and tube of the uterus ...
The internal genitalia consist of two accessory ducts: mesonephric ducts (male) and paramesonephric ducts (female). The mesonephric system is the precursor to the male genitalia and the paramesonephric to the female reproductive system. [8] As development proceeds, one of the pairs of ducts develops while the other regresses.
The mesonephric duct, also known as the Wolffian duct, archinephric duct, Leydig's duct or nephric duct, is a paired organ that develops in the early stages of embryonic development in humans and other mammals. It is an important structure that plays a critical role in the formation of male reproductive organs.
The ejaculatory ducts (ductus ejaculatorii) are paired structures in the male reproductive system. [1] Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. [2] They pass through the prostate, and open into the urethra above the seminal colliculus.
The septa testis are fibrous partitions of the testis dividing the testis into compartments - the lobules of the testis.The septa are formed by extensions of the tunica albuginea - the dense fibrous connective tissue surface covering of the testis - into the substance of the testis.
