The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
What gland produces sperm and testosterone?
The two testicles (or testes) produce sperm and the male sex hormone testosterone.
Which gland controls sperm production?
Within the brain, the hypothalamus and anterior pituitary control sperm production. The hypothalamus secretes gonadotropin-releasing hormone (GnRH), which acts on the anterior pituitary gland, stimulating it to release follicle stimulating hormone (FSH) and leutinizing hormone (LH).
What is the epididymis?
The epididymis is a long, coiled tube that transports sperm from the testes to the vas deferens . The epididymis consists of three parts, the caput (head), corpus (body), and cauda (tail.) During their journey through the various parts of the epididymis, sperm mature and gain the ability to swim.
Is salivary gland an endocrine gland?

The external male genitalia include the penis , urethra, and scrotum. The internal male genitalia include the seminal vesicle, testes, vas deferens, epididymis, prostate, bulbourethral gland, and ejaculatory duct. The penis is the main part of external male genitalia, which has both sexual and bodily functions.
What is severed in a vasectomy?
During the surgery, 2 tubes called the vas deferens are cut and sealed. The vas deferens carry sperm from testicles to the urethra. The urethra is the tube inside the penis. Once they are cut, sperm can’t get into the semen or out of the body.
Which glands are both endocrine and exocrine called?
The pancreas and liver are both endocrine AND exocrine organs. As an endocrine organ, the pancreas secretes the hormones insulin and glucagon. As an exocrine organ, it secretes several enzymes that are essential for digestion in the small intestine.
Which is master gland?
The pituitary gland is sometimes called the “master” gland of the endocrine system because it controls the functions of many of the other endocrine glands.
What is vas deferens?
The ductus deferens, or vas deferens, is a fibromuscular tube that is continuation of the epididymis and is an excretory duct of the testis . Each ductus is 30-45 cm in length and serves to transport sperms cells from the respective epididymis to the ipsilateral ejaculatory duct.
What is submandibular gland?
The submandibular gland is the second largest of the three main salivary glands , which also include the parotid and sublingual glands. The submandibular glands are paired major salivary glands that lie in the submandibular triangle.
How is testosterone produced?
Testosterone is produced by the gonads (by the Leydig cells in testes in men and by the ovaries in women), although small quantities are also produced by the adrenal glands in both sexes. It is an androgen, meaning that it stimulates the development of male characteristics.
Are testes glands?
The testes are two oval-shaped male reproductive glands that produce sperm and the hormone testosterone.
Where is testosterone created?
The brain’s hypothalamus and pituitary gland control testosterone production, which is produced in the gonads where the Leydig cells make and secrete testosterone.
Which glands release sweat and saliva?

What are endocrine glands?
An organ that makes hormones that are released directly into the blood and travel to tissues and organs all over the body . Endocrine glands help control many body functions, including growth and development, metabolism, and fertility. Some examples of endocrine glands are the pituitary, thyroid, and adrenal glands.
What gland produces aldosterone?
Adrenal glands produce hormones required for healthy life. The adrenal cortex produces hormones that controls sex (androgens, estrogens), salt balance in the blood (aldosterone), and sugar balance (cortisol).
Which hormone is secreted by pituitary gland?
There are four hormones secreted by the anterior pituitary gland that control the functions of other endocrine glands. These hormones include thyroid-stimulating hormone (TSH) , adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH).
What are the 8 hormones produced by the pituitary gland?

- FSH: Follicle-stimulating hormone. ...
- LH: Luteinizing hormone. ...
- GH: Growth hormone. ...
- PRL: Prolactin. ...
- TSH: Thyroid-stimulating hormone.
What is the posterior pituitary gland?
The posterior pituitary (or neurohypophysis) comprises the posterior lobe of the pituitary gland and is part of the endocrine system. Hormones known as posterior pituitary hormones are synthesized by the hypothalamus, and include oxytocin and antidiuretic hormone.
What is the name of girl private part?
The vulva is the part of your genitals on the outside of your body — your labia, clitoris, vaginal opening, and the opening to the urethra (the hole you pee out of). While vaginas are just one part of the vulva, many people say “vagina” when they really mean the vulva.

The likelihood of getting pregnant after a vasectomy is almost zero when couples wait at least 3 months following the procedure to have sex without birth control. After a vasectomy, a doctor will test the semen to assess whether there are sperm present.
What’s the seminal vesicle?
seminal vesicle, either of two elongated saclike glands that secrete their fluid contents into the ejaculatory ducts of some male mammals . ... The secretion of the seminal vesicles constitutes the bulk of the seminal fluid (semen).
What are the accessory glands?
The accessory glands of the male reproductive system are the seminal vesicles, prostate gland, and the bulbourethral glands . These glands secrete fluids that enter the urethra.
Which gland has both endocrine and exocrine functions quizlet?

Does a vasectomy make your balls sag?
When performed by our highly skilled doctors an open-ended vasectomy procedure should cause little to no scarring, and certainly will not visibly change the size or shape of your testicles . The aim is to only interrupt the plumbing that transports the sperm and not interfere with blood vessels.
What is ejaculatory duct?
Definition of ejaculatory duct
: a duct through which semen is ejaculated specifically : either of the paired ducts in the human male that are formed by the junction of the duct from the seminal vesicle with the vas deferens and that pass through the prostate to empty into the urethra.
Which gland is known as dual gland?
Pancreas Essentials
The pancreas is unique in that it’s both an endocrine and exocrine gland. In other words, the pancreas has the dual function of secreting hormones into blood (endocrine) and secreting enzymes through ducts (exocrine).
Which gland makes oxytocin?
The peripheral actions of oxytocin mainly reflect secretion from the pituitary gland .
What is anterior pituitary gland?
A major organ of the endocrine system, the anterior pituitary (also called the adenohypophysis or pars anterior) is the glandular, anterior lobe that together with the posterior lobe (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis).
What are Submaxillary nodes?
Anatomical terminology. The submandibular lymph nodes (submaxillary glands in older texts), three to six in number, are lymph nodes beneath the body of the mandible in the submandibular triangle , and rest on the superficial surface of the submandibular gland.

What is parotid duct?
The parotid duct, or Stensen duct, is the major duct of the parotid gland , which is the major salivary gland. This duct serves as a conduit for saliva between the substance of the parotid gland and the oral cavity.
