  • Label the diagram.

    Label the diagram.

  • The scrotum is separated into two compartments, by what muscle?

    The dartos muscle.

  • What us the temperature required for spermatozoa to survive?

    2-3 degrees

  • What is the temperature of the testes controlled by?

    Cremaster muscle

  • When the dartos muscle contracts what happens to the scrotum?

    The scrotum becomes tight to reduce heat loss.

  • What is the condition called when the testes fail to descend through the inguinal canals?

    Cryptochidism

  • What is the outermost layer of the testes?

    Tunica vaginalis

  • Where are sperm cells made (spermatogenesis)?

    In the testes, particularly inside the seminiferous tubules in the tunica albunigea.

  • Label this diagram.

    Label this diagram.

  • Where does sperm mature?

    The epididymis.

  • What do sustentacular cells do?

    - Nourish spermatocytes, spermatids and spermatozoa

    - Mediate the effects of testosterone and FSH

    - Secrete fluid for sperm transport (semen)

    - Breaks down cytoplasm of spermatids to turn into sperm cells

  • Label this diagram.

    Label this diagram.

  • What does luteinizing hormone (LH) do?

    Stimulates cells in the testes to produce testosterone.

  • How does testosterone affect spermatogenesis?

    The more testosterone the more sperm is produce, therefore it stimulates spermatogenesis.

  • Describe the pathway of sperm.

    Seminiferous tubules (created) > straight tubules > rete testis > efferent ducts > epididymis > ductus deferens

  • What do the seminal vesicles secrete?

    An alkaline, viscous fluid called semen.

  • What is the purpose of semen?

    - To transport spermatozoa

    - Provides nutrients and ATP

    - Neutralizes the acidity in the female vagina

  • An erection is a ___ reflex.

    parasympathetic

  • Ejaculation is a ___ reflex.

    sympathetic

  • What are the accessory sex glands and what do they do?

    - seminal vesicles

    - prostate

    - bulbourethral glands

    Produce semen
