Reproductive Anatomy- Lecture 2

Question 1

Testes

Answer 1

gametes and hormones (testosterone)

Question 1

Infundibulum

Answer 1

Holds the fimbriae and is able to help “catch” the ovulated egg

Question 2

Bicornuate uterus

Answer 2

Poor to moderately developed uterine horns. Seen in mares and cows or Highly developed uterine horns. Seen in dogs, cats, sows

Question 2

Board ligament

Answer 2

Supports uterine track. Made up of: mesometrium, mesosalpinx, mesovarium.

Question 3

Penis

Answer 3

copulatory organ and semen deposition

Question 4

Epididymides

Answer 4

sperm maturation and transport

Question 4

Os

Answer 4

An opening. Examples: os penis, os external cervix

Question 5

Pampiniform plexus

Answer 5

network of many small veins found in the spermatic cord

Question 7

Uterus

Answer 7

environment for sperm transport, embryogenesis and attachment of the conceptus

Question 7

Vas deferens

Answer 7

Functions to transport sperm. Attached at tail of epididymus

Question 8

Sigmoid flexure

Answer 8

An S shaped curve in the penises of rams and bulls.

Question 9

Accessory sex glands

Answer 9

production of seminal plasma

Question 10

Pelvic urethra

Answer 10

semen transport

Question 12

Simplex uterus

Answer 12

No uterine horns. Seen in primates

Question 13

Polytocous

Answer 13

Litter bearing animals

Question 14

Monotocous

Answer 14

Animals bearing only one offspring at a time. Twins and triplets a rarity

Question 15

Oviducts

Answer 15

environment for fertilization and development of the embryo

Question 16

Non-equine vs equine ovary makeup

Answer 16

Non-equine: cortex on outside, medulla on inside Equine: cortex on inside, medulla on outside. with ovulation fossa

Question 17

Prostate

Answer 17

All species we study in reproduction have prostates.

Question 18

Spermatic cord

Answer 18

Testicular artery, vein, and nerve. Ductus deferens. Cremaster muscle. Lympathic tissue. Pampiniform plexus.

Question 19

Layers of testis (superficial to deep)

Answer 19

visceral layer of tunica vaginalis tunica albuginea (capsule of testis) seminiferous tubules mediastinum testis (aka: hilum of testis)- efferent ductules and rete testis

Question 20

Ampulla vs. Isthmus

Answer 20

Parts of uterine tube. Ampulla has a much wider diameter then the isthmus portion

Question 22

Ovaries

Answer 22

gametes and hormones

Question 24

Cervix

Answer 24

mucus secretion (estrus); cervical seal ( during pregnancy)

Question 25

Vagina

Answer 25

copulatory organ

Question 26

Follicle to Corpus Albicans

Answer 26

primordial follicle, primary follicle, secondary follicle, antral follicle, corpus luteum, corpus albicans

Question 27

Ovarian bursa

Answer 27

a pouch formed by the mesosalpinx and the mesovarium that encloses the infundibulum of the uterine tube and the ovary. It is shallow in the mare and does not enclose the ovary. It is capacious in sows and deep with a fat-filled wall in the bitch.

Question 28

External genitalia

Answer 28

Vulva between dorsal and ventral commissure. Cuntaneous bridge is the space between the vulva and anus.

Question 29

Fimbriae

Answer 29

Finger-like projections from the infundibulum that “catch” the egg and direct it toward ovarian bursa
