seminal gland

Examples of seminal gland in the following topics:

• Accessory Sex Glands

  • The accessory sex glands produce seminal fluid and clean and lubricate the urethra.
  • The accessory sex glands, including the seminal, prostate glands, and bulbourethral glands, produce seminal fluid and clean and lubricate the urethra.
  • Each seminal gland forms as an outward growth of the wall of ampulla of each vas deferens.
  • The excretory duct of the seminal gland opens into the vas deferens as it enters the prostate gland.
  • The bulbourethral glands are compound tubulo-alveolar glands, each approximately the size of a pea.

• Semen

  • Semen is an organic fluid, also known as seminal fluid, that may contain spermatozoa.
  • It is secreted by the gonads (sexual glands) and can fertilize female ova.
  • Semen is produced and originates from the seminal vesicles, located in the pelvis.
  • During the process of ejaculation, sperm pass through the ejaculatory ducts and mix with fluids from the seminal vesicle, the prostate, and the bulbourethral glands to form semen.
  • The bulbourethral glands secrete a clear fluid to lubricate the lumen of the urethra.

• Anatomy of the Male Reproductive System

  • They include the vas deferens, seminal vesicles, prostate gland, and bulbourethral (Cowper's) glands.
  • Seminal vesicles: Sac-like pouches that attach to the vas deferens near the base of the bladder.
  • The seminal vesicle fluid makes up most of the volume of a man's ejaculate.
  • Bulbourethral (Cowper's) glands: Pea-sized structures located on the sides of the urethra just below the prostate gland.
  • These glands produce a clear, slippery fluid that empties directly into the urethra.

• Testes Ducts

  • The sperm are transferred from the vas deferens into the urethra, collecting secretions from the male accessory sex glands such as the seminal vesicles, prostate gland, and bulbourethral glands, which provide the bulk of semen.

• Male Sexual Response

  • The muscles of the pelvic floor, the ductus deferens (between the testes and the prostate), the seminal vesicles, and the prostate gland may begin to contract in a way that forces sperm and semen into the urethra inside the penis.

• Premature Ejaculation

  • It involves deposition of seminal fluid from the ampullary vas deferens, seminal vesicles, and prostate gland into the posterior urethra.

• Overview of the Male and Female Reproductive Systems

  • One important type of parental care is the use of the mammary glands in the female breasts to nurse the baby.
  • The second category, the ejaculatory fluid-producing glands, includes the seminal vesicles, prostate, and vas deferens.
  • The final category, used for copulation and deposition of the spermatozoa (sperm) within the female, includes the penis, urethra, vas deferens, and Cowper's gland.
  • One of the most significant features of the human penis is the coronal ridge underneath the gland around the circumference of the shaft.
  • During intercourse, this area is lubricated by mucus secreted by the Bartholin's glands.

• Overview of the Adrenal Glands

  • In mammals, the adrenal glands (also known as the suprarenal glands) are endocrine glands that sit atop the kidneys.
  • In mammals, the adrenal glands (also known as the suprarenal glands) are endocrine glands that sit atop the kidneys.
  • In humans, the right adrenal gland is triangular shaped, while the left adrenal gland is semilunar shaped.
  • Each adrenal gland has two distinct structures, the outer adrenal cortex and the inner medulla—both produce hormones.
  • The adrenal glands are triangular-shaped organs on top of the kidneys.

• Sweat (Sudoriferous) Glands

  • Sweat glands, also known as sudoriferous glands, are distributed over most of the body surface.
  • Sweat glands, also called sudoriferous glands, are simple tubular glands found almost everywhere on our body. 
  • The other kind of sweat glands are known as apocrine glands. 
  • Unlike eccrine glands, the exact function of apocrine glands is unknown and debated.

• Overview of the Parathyroid Glands

  • The parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone.
  • The parathyroid glands are small endocrine glands—approximately the size of a grain of rice—in the neck that produce parathyroid hormone.
  • Humans usually have four parathyroid glands, which are usually located on the posterior surface of the thyroid gland, or, in rare cases, within the thyroid gland itself or in the chest.
  • The two parathyroid glands on each side that are positioned higher are called the superior parathyroid glands, while the lower two are called the inferior parathyroid glands.
  • The parathyroid gland in relation to the thyroid gland.
