: connect seminiferous tubules to effert ducts
: Connect rete testis to head of epididymis
What cells are found in the Parenchyma?
: Develop male gamete
: Produce testosterone
1. Ovary (Follicle)
2. Broad Ligament
What are the 3 parts of the oviduct and their location?
: End of Oviduct
: Closer to Infundibulum
: From Ampulla to Uterus
What are the functions of the 3 parts of the oviduct?
: First picks up the egg
: Site of fertilization
: thinner portion
What is the Broad Ligament?
Suspensory tissue that supports the female reproductive tract
Houses vascular network, lymphatic drainage, and nerves
What are the 3 components of the Broad Ligament and what do they support?

What Hormone is release from the PVN of the hypothalamus?
What hormones are produced from the Anterior Pituitary Gland?
FSH and LH
What hormones are released from the Posterior Pituitary Gland?
Oxytocin (stored and released but produced in PVN)
What is the function of the Cervix?
Passageway for sperm following breeding
Seals off uterus in pregnancy
Passageway for fetus at birth
1. Corpus Luteum
What is the function of the Uterus?
Passage way for sperm
Houses developing embryo/fetus
What are the 3 layers (from outside to in) of the Uterus and what are their functions?
: Contraction for sperm movement and birth
: Houses carnucles and glands
What is the function of the Vagina?
Receives penis during Copulation
Secretes small amounts of mucus
Passageway for fetus at birth
1. Layers of Testicular Capsule
What are the 2 layers of the Testicular Capsule?
1. Visceral Vaginal Tunica

What is the pathway of sperm in the male tract?
Head of Epididymis
Body of Epididymis
Tail of Epididymis
Is this a sow or a gilt? How do you know the difference?
Gilt: Has a smaller reproductive tract and the ovaries have less structures present on them
What is the function of the Vulva?
Passageway for urine
Receptor for penis during copulation
Passageway for fetus during birth
Protection - prevents material from environment from entering tract
What are the functions the the Epididymis?
Receive sperm from testis
Transports sperm to urethra
What are the 3 parts of the Epididymis and their functions?
: Receive sperm from testes; Concentrates sperm
: Sperm maturation
: Sperm storage
What does the Testes produce?
Produce male gamete
What are the 3 parts of Spermatic Cord?
1. Pampiniform Plexus
2. Cremaster Muscle
3. Vas Deferens
What are the functions of the Spermatic Cord?
Provide attachment and support of the testis to the body
Provide vascular, nervous, and lymphatic connection to body
Pulse pressure eliminator
What are functions of the Paniform Plexus?
What are functions of the Cremaster Muscle?
Aid in temperature control
Primary muscle supporting the testis
*Not responsible for long-term raising
What are the functions of the Vas Deferens?
: Steady smooth contractions
: Increase contractions (strength and number)
What is the function of the Urethra?
Transport of sperm from vas deferens to the outside environment
What are 3 glands in the Male?

2. Prostate Glands
3. Bulbourethral Glands
What is the function of Vesicular Glands?
Add volume to ejaculate
What are the functions of the Prostate Gland?
Secrete fluid to clean and lubricate urethra
Add small amount of volume to semen
What is the function of the Bulbourethral Glands?
Produce viscous secretion that will cause seminal plasma to coagulate following ejaculation
What is the function of the Penis?
Male organ of copulation
What is the Sigmoid Flexure?
Part of Penis that has a S-shaped configuration
What are Retractor Penile Muscles?
Found in the Sigmoid Flexure
: Extended, relaxed
