Spermatic cord, vas deferens, and seminal vesicles: A detailed analysis of the structure and secondary sexual characteristics of the male internal reproductive organs.

(5) Spermatic cord, vas deferens, and ejaculatory duct: The spermatic cord originates from the testis...

A circular cord-like structure extending from the upper end of the testicle to the abdominal ring of the inguinal canal. Spermatic cord.

It originates from the internal inguinal ring and terminates at the posterior border of the testis, forming the suspended testis.

The soft septum of the testicle and epididymis, one on each side, with a total length of 14 cm.

Approximately 1 meter long. The spermatic cord contains the vas deferens, arteries, veins, and...

Nerves and celluloid tissue. Arteries include the testicular artery and the vas deferens artery.

The spermatic cord is formed by the pampiniform plexus of veins.

The blood and lymphatic circulation pathways of the testes, epididymis, and vas deferens are also...

It is the main factor in ensuring the spermatogenic function of the testes and the transport of mature sperm.

The pathway. The vas deferens is one of the main structures within the spermatic cord, originating from...

The tail of the epididymis enters the pelvic cavity via the inguinal canal. The vas deferens terminates in the vas deferens.

The ureter runs midway between the bladder and the urethra, and its distal end dilates.

It forms the ampulla of the vas deferens and eventually merges with the seminal vesicle duct. Its end...

The ejaculatory duct merges with the excretory duct of the seminal vesicle to form the ejaculatory duct, which passes through the prostate gland.

The gland opens into the urethra, has thick walls, and is approximately 40–46 cm in length.

It is about 2-3 millimeters in diameter and is the vas deferens. The vas deferens is where sperm travels from the epididymis.

The ejaculatory duct is the only passageway through which semen is transported to the prostatic urethra.

The continuation of the vas deferens after its ductal fossa joins the seminal vesicle duct. Ejaculatory duct.

It is very short, only about 2 centimeters long, and the tube wall is very thin.

(6) Seminal vesicles, prostate gland, and bulbourethral glands: Seminal vesicles

It consists of a pair of flat, elongated, sac-like glands, one on the left and one on the right, with concave surfaces.

The surface is uneven and nodular, located on the outer side of the distal end of the vas deferens and the bladder.

Below and behind, its thin end is the excretory duct of the seminal vesicle, which...

The ends of the vas deferens merge to form the ejaculatory ducts, which are located in the prostatic urethra.

The seminal vesicle opens into the urethra. It is approximately 4-5 cm long and 2 cm wide.

Rice, with a volume of approximately 4 ml. The seminal vesicle is a tortuous glandular sac, its...

The secretion is mainly seminal fluid, accounting for about 70% of semen.

It plays an important role in sperm survival. The prostate gland is like an chestnut.

The gland is shaped like a log, with a central groove and raised sides.

It connects upwards to the bladder, and its tip points downwards to the superior fascia of the urogenital diaphragm.

It weighs approximately 18 grams. The prostate gland secretes prostatic fluid, mainly...

Seminal fluid contains various trace elements and enzymes.

Proximal to the caruncle, the smooth muscle strengthens and forms what is known as the anterior prostatic sphincter.

It has the function of preventing retrograde ejaculation. Bulbourethral glands: left and right.

One of each, located in the deep perineal sac between the superior and inferior fascia of the urogenital diaphragm.

It opens into the proximal bulbar urethra. It can secrete a small amount of fluid, which is a component of seminal plasma.

What are the secondary sexual characteristics of men?

Secondary sexual characteristics, also called accessory sexual characteristics, refer to those other than the genitals.

In terms of appearance (body shape, posture, appearance, voice, etc.)

Differences in appearance (on the face) are external manifestations of sexual development. (Just now)

Is a newborn baby a boy or a girl? The sex is determined by the genitals.

Official: Those with a penis are boys, those with a vagina are girls. Thus, the penis and vagina become secondary sexual characteristics.

--Characteristics that differ between the sexes. Reproductive organs that are formed at birth are called...

Principal sexual characteristics, or primary sexual characteristics.

Besides the physiological differences in the structure of the reproductive systems of men and women

Besides being clearly different, the characteristics they form are also significantly different.

Similarly, men are often taller, stronger, and more muscular.

Powerful, with a prominent Adam's apple, a deep voice, and thick, long hair.

Facial hair and other physical features are more pronounced in men compared to women, particularly in the shoulders and chest.

Well-developed bones and muscles, with shoulders wider than hips. These constitute male secondary sexual characteristics.

**5.** What is the **third** sexual characteristic?

Tertiary sexual characteristics are a new concept proposed by some medical experts.

Some experts believe that third sexual characteristics refer to the physical characteristics of men and women beyond their biological...

In addition to the differences in physical aspects, there are also differences in social psychology.

It is a gender characteristic that gradually forms due to social influences, such as hair

Differences in style, adornment, gait, and personality

Points. These differences between men and women are the result of acquired social and cultural influences.

It was gradually formed under the influence of the environment; some people call this...

It is referred to as "tertiary sexual characteristics" to distinguish it from primary and secondary sexual characteristics.

Primary and secondary sexual characteristics are natural biological sex characteristics.

Tertiary sexual characteristics, on the other hand, are artificial and social, and can change on their own.

In daily life, the distinction between male and female genders is often based on "tertiary sexual characteristics".
