1

Name the two major ligaments that support the weight of the mammary gland in the cow, goat and sheep. State where each connects to the body

Medial suspensory ligament attaches the muscle to the abdominal wall
Lateral suspensory ligament attaches to the pelvic wall

2

Name the vessel by which blood entering the bovine udder

Pudendal artery

3

Name the vessel by which the blood exits the bovine udder

Pudendal artery
Caudal superficial epigastric

4

Name the types of cells associated with the mammary gland

Mammary epithelial cells
Myoepithelial cells

5

What is mastitis

Inflammation in the udder caused by infection with bacteria or fungi

6

Name two types of penis and describe and what species has which penis

Musclo-cavernous
Increase of diameter is length due to engorgment
i.e. rats, dogs and humans
Fibro-elastic
Retractor muscle and sigmoid flexure extend due to the prupuce, small amount of increase in diameter
i.e. boar, bull and ram

7

What is the orientation of the cat penis

The cats penis direction is caudal

8

Semen consists of two main components. Name them and their sources

Sperm - located in the testis
Seminal fluids - located in the accessory gland make up 95% of semen

9

Name the accessory sex glands in the male reproductive tract

Seminal vesicle
Ampulla
Cowpers gland
Prostate gland

10

Name the cell in the testis that produce androgens

Leydig cells

11

Name the functions of the testis

Storage and production of sperm
Androgen production

12

Name the functions of the epididyimus

Transport of sperm
Maturation of sperm
Concentration of sperm
Secretion of nutrients
Storage of sperm

13

Name the function of the Vas Deferens

Transport of sperm to urethra

14

Name the function of the accessory gland

Production of the seminal fluid, makes up 95% of the semen

15

Fully name the tissue that lines the teat canal and purpose of it.

Keratinised stratified squamous epithelium
Acts as plug to prevent entry of bacteria or fungi in the teat canal

16

What is the function of the supramammary lymph nodes

Protection against infections
Drains the intersitial fluids

17

Whats another name for the 'milk vein'?

20

Whats the name of the hormone that stimulates the milk synthesis?

Prolactin

21

What is the name of the hormone that is secreted by the posterior pituitary gland?

Oxytocin

22

Whats another name of a Leydig cell?

Interstitial cells

23

The production of sperm in the seminferous tubules is controlled by what time of cell

Sertoli cells

24

What temperature range do most mammals sperm develop best?

34-35 degrees
