Anatomy and Functions of the Male Reproductive System

1. What is the German term 'der Hoden' commonly referring to?

Liver

Organ where sperm is made

Heart

Knee joint

Der Hoden in German refers to the testis/testicle which is the organ where sperm is made.

Explanation

Der Hoden in German refers to the testis/testicle which is the organ where sperm is made.

2. What are the functions of the penis?

C. It is solely responsible for producing hormones.

B. It has only urinary function.

D. It is used for digestion purposes.

A. It has only reproductive function.

The penis serves both reproductive and urinary functions, allowing males to engage in sexual intercourse and pass urine. It is not responsible for hormone production or digestion.

Explanation

The penis serves both reproductive and urinary functions, allowing males to engage in sexual intercourse and pass urine. It is not responsible for hormone production or digestion.

3. What is sperm in terms of biology?

D) A type of hormone produced in the pituitary gland

Male sex cell or gamete (product of meiosis)

C) The smallest bone in the human body located in the ear

A) Female sex cell or gamete (product of mitosis)

B) A type of virus that infects the reproductive system

Sperm, also known as spermatozoon or sperm cell, is the male sex cell or gamete resulting from the process of meiosis. It is involved in sexual reproduction.

Explanation

Sperm, also known as spermatozoon or sperm cell, is the male sex cell or gamete resulting from the process of meiosis. It is involved in sexual reproduction.

4. What is the function of the epididymis?

B. Transport of urine to the bladder.

C. Production of seminal fluid.

A. Production of testosterone.

D. Removal of waste products from the blood.

Sperm is stored and matures here

The epididymis is a highly coiled tube located behind each testicle where sperm is stored, matures, and gains motility before ejaculation. It is not involved in the production of testosterone, transport of urine, production of seminal fluid, or removal of waste products from the blood.

Explanation

The epididymis is a highly coiled tube located behind each testicle where sperm is stored, matures, and gains motility before ejaculation. It is not involved in the production of testosterone, transport of urine, production of seminal fluid, or removal of waste products from the blood.

5. What is the function of seminal vesicles?

C) Aid in the production of saliva for digestion.

A) Produce testosterone to stimulate sperm production.

B) Store urine before it is expelled from the body.

Seminal vesicles are responsible for secreting fluid that contributes to the majority of semen volume during ejaculation, providing nutrients and enzymes for sperm cells.

Explanation

Seminal vesicles are responsible for secreting fluid that contributes to the majority of semen volume during ejaculation, providing nutrients and enzymes for sperm cells.

6. What is semen in German?

Protein-rich food.

Seed of a plant.

Growth hormone.

FLUID made by the glands; it helps sperm live longer, travel better and feeds them

Semen, or 'der Samen' in German, refers to the fluid made by the glands that aids in the survival and transportation of sperm.

Explanation

Semen, or 'der Samen' in German, refers to the fluid made by the glands that aids in the survival and transportation of sperm.

7. What is the function of the urethra / die Harnsamenröhre?

Sac that stores urine in the body

Muscle that controls bladder function

Vessel that carries blood to the kidneys

Tube inside the penis that allows passage of urine and semen

The urethra is a tube inside the penis that allows the passage of both urine and semen, not blood to the kidneys, a muscle controlling bladder function, or a sac storing urine.

Explanation

The urethra is a tube inside the penis that allows the passage of both urine and semen, not blood to the kidneys, a muscle controlling bladder function, or a sac storing urine.

8. What is the function of the bulbourethral gland (Cowper's)?

Secretes mucus to aid in digestion.

Helps in the production of testosterone.

Makes acidic fluid that cleans the urethra (from urine) to protect sperm

Produces hormones that regulate urinary functions.

The bulbourethral gland, also known as Cowper's gland, is responsible for producing an acidic fluid that cleans the urethra from urine to protect sperm during ejaculation.

Explanation

The bulbourethral gland, also known as Cowper's gland, is responsible for producing an acidic fluid that cleans the urethra from urine to protect sperm during ejaculation.

9. What is the role of the prostate?

Aids in digestion by producing enzymes.

Produces about 20-30% of the milky fluid in semen

Filters waste products from the blood.

Regulates body temperature by controlling sweat production.

The prostate, a gland in the male reproductive system, produces fluid that mixes with sperm and other fluids during ejaculation to form semen. This fluid helps nourish and protect sperm cells.

Explanation

The prostate, a gland in the male reproductive system, produces fluid that mixes with sperm and other fluids during ejaculation to form semen. This fluid helps nourish and protect sperm cells.

10. Scrotum / der Hodensack

A type of citrus fruit

Sac that holds testicles and controls their temperature

A type of hat

A type of facial hair style

The scrotum, also known as der Hodensack in German, is a sac that holds the testicles and regulates their temperature to ensure proper sperm development.

Explanation

The scrotum, also known as der Hodensack in German, is a sac that holds the testicles and regulates their temperature to ensure proper sperm development.

11. What is the definition of glans (die Eichel)?

A geological formation made of limestone.

A type of nuts commonly found in the Amazon rainforest.

Head of penis and opening of the urethra; attaches to foreskin (Forehaut) or prepuce

An organ found in the digestive system.

The glans refers to the head of the penis in male anatomy and is an important part of the reproductive system. It plays a role in sexual stimulation and houses the opening of the urethra for urine and semen. It is often covered by the foreskin or prepuce.
