17
Q

What is the function of Mammary glands?

A

Colostrum contains antibodies, important for immune transfer

18
Q

What are Mammary glands made up from?

A

body (mammae) and a teat, collections of mammary glands are called udders- each gland contains one or more secretory units

19
Q

Supernumerary teats

A

any teat that is in excess to the normal amount, usually develops from extra buds

20
Q

What produces milk?

A

Mammary cuboidal epithelial cells that line the alveoli

21
Q

Alveoli are…

A

grouped into lobules and separated by connective tissue

22
Q

Lobules are…

A

Grouped into lobes and separated by Adipose tissue

23
Q

myoepithelial cells

A

muscle cells that surround alveoli and push milk out of the alveolus

24
Q

Intralobular ducts

A

drains the alveolus

25
Q

interlobular ducts

A

outside of the lobule

26
Q

lactiferous sinus

A

Where milk is stored (teat sinus and gland sinus)

27
Q

Function of smooth muscle sphincter

A

Prevents the leakage of milk

28
Q

Let down

A

When the myoepithelial cells contract and relax the taet sphincter muscle

29
Q

mucosal fold

A

marks the transition between gland and teat sinus

30
Q

When are mammary glands fully developed?

A

at the height of lactation, full size and function during pregnancy

31
Q

Keratin plug

A

During the dry period, stops material getting in

32
Q

median suspensory ligament

A

separates left and right side, has elasticity

33
Q

lateral suspensory ligaments

A

hold the outside of the glands

34
Q

How do birds lose heat?

A

respiratory evaporative cooling and the skin (vasodilation)

35
Q

Lipogenic epidermis

A

deposits lipid film onto feathers

36
Q

What 3 sebaceous glands do birds have?

A

Preen, Aural and Vent

37
Q

Function of the preen gland

A

Produces an oily secretion for waterproofing, feather care and antimicrobrial/ antiparasite function

38
Q

What happens if birds don’t groom properly

A

Vitamin D precursor not spread over feathers can lead to weak bones

39
