Scrotum
A flat, muscular sheet adhered to the inner surface of the scrotal skin that contracts and moves the testes toward the body for warming and relaxes and moves the testes away from the body for cooling
Tunica dartos
Contains the vas deferens, cremaster muscle, and pampiniform plexus and provides a pathway to the testis for vasculature, lymphatics, and nerves
Spermatic cord
What surrounds the vas deferens and pampiniform plexus?
parietal vaginal tunic
The strip of muscle that lends support to the testis and moves the testes closer tothe body for temperature regulation and contractions assist with the movement of blood through the pampiniform plexus
Cremaster Muscle
The dense connective tissue covering the testis
Tunica albuginea

seminiferous tubules
“Nurse cells” that help sperm to develop and mature and secrete fluid for sperm transport
Sertoli cells
Sperm with the head and tail visible
Spermatozoa
Spermatozoa are produced in the ______
Testes
Interstitial endocrine cells in the testes that produce androgens such as testosterone and are found outside of the seminiferous tubules in the interstitial space
Leydig Cells
Leydig cells are _____ cells
Endocrine
A duct that functions in transport, maturation, and storage of sperm.
Epididymis
A straight tube with a thick muscular wall that carries sperm from the epididymis to the urethra and expulses semen during maturation.
Vas Deferens
Dilation of the vas deferens where it joins the urethra that functions as an accessory sex gland. Which species does not have this?
- Ampulla
- Boar
The accessory sex gland that adds fluid to add bulk and nutrients such as fructose to the ejaculate. Which species does not have this?
- Seminal Vesicles
- Canine
A compound exocrine gland that is a single, unpaired gland. It is H-shaped in the _____ and is the primary accessory sex gland in the _____.
- Prostate gland
- Stallion
- Dog
What are the two accessory sex glands in the dog?
Ampulla and prostate
Exocrine gland that lubricates the urethra, adds the gel-like component of boar semen that forms a cervical plug in naturally bred females. In ____ they are large.
- Bulbourethral gland
- Boars
The free end of the penis that is heavily populated with sensory nerve endings. Stimulation results in ejaculation.
Glans Penis
Which species have a fibroelastic penis?
Bull, boar, ram
