1
Q

The fluid secreted by the seminiferous tubule’s and the epididymis account for only what percent of the volume of semen

A

5

2
Q

The fluid components of semen is a mixture of secretions from what glands

A

Seminal glands
Prostate gland
Bulbourethral glands

3
Q

The major function of
Seminal glands
Prostate gland
Bulbourethral glands

A
  1. Activating spermatozoa
  2. Providing the nutrients spermatozoa need for motility
  3. Propelling spermatozoa and fluids along the reproductive tract
  4. Producing buffers that counteract the acidity of the urethral and vaginal environments
4
Q

The vas deferens on each side ends at the junction between the ampulla and the duct that drains the

A

Seminal gland

5
Q

The seminal gland also called the seminal vesicles are

A

Tubular glands embedded in connective tissue on either side of the midline between the posterior wall of the bladder and the rectum.

15 cm

6
Q

The seminal glands secrete about—-% of the volume of semen.

A

60

7
Q

The glandular fluid has the same osmotic concentration as that of

A

Blood plasma

8
Q

The secretion of the seminal glands contains

A
  1. Higher concentrations of fructose
  2. Prostaglandins, which can stimulate smooth muscle contractions
  3. Fibrinogen, which after ejaculation forms a semen clot in the vagina
9
Q

When mixed with the secretions of the seminal glands, spermatozoa undergo the first step in

A

Capacitation and begin beating their flagella

10
Q

The secretions of the seminal glands are discharged into the ejaculatory duct at

A

Emission: when peristaltic contractions are underway in the ductus deferens, seminal glands, and prostate gland.

These contractions are under the control of the sympathetic nervous system

11
Q

Prostate gland

A
  1. Muscular, round, 4 cm in diameter.
  2. In circles the proximal portion of the urethra.
  3. Glandular tissue of the prostate consists of a cluster of 30 to 50 compound Tubuloalveolar glands.
  4. These glands are surrounded by a thick blanket of smooth muscle fibers.
12
Q

Prostatic fluid

A
  1. Slightly Acidic
  2. Makes up 20 to 30% of volume of semen
  3. Contains Seminalplasmin
13
Q

Seminalplasmin

A

A protein with antibiotic properties that help prevent urinary tract infection

14
Q

Prostatitis

A
  1. Can result from bacterial infections

2. Symptoms: lower back pain, perineum or rectum pain, painful urination, discharge of mucus from urethral opening

15
Q

Bulbourethral glands or Cowper’s glands

A
  1. Compound tubular mucous glands located at the base of the penis
  2. Round, diameter is nearly 10 mm.
  3. The duct of each gland travels alongside the penile urethra for 3 to 4 cm before emptying into the urethral lumen.
16
Q

Bulbourethral glands or Cowper’s glands secretion

A
  1. Thick, alkaline mucus
  2. Helps neutralize any urinary acid
  3. Lubricate the glans penis, or tip of penis
