2- INTERGUMENTARY Flashcards
Types of Hair
Guard hair
Wool hair
Tylotrich haie
Long Hair
Bristles
The hair type of
the fleece of sheep
Wool hairs
large hair
follicles are rapidly adapting
mechanoreceptors
Tylotrich hair
the long hair of the
horse –forelock, mane, tail and “feathers”
(behind the fetlock)
Long (horse) hair
the hair coat of the pig
Bristles
(eyelashes)
Cilia
(hairs of the nostrils)
vibrissa
(hair of the submandibular
region ) of the goat
Beard
Lacks guard hairs so that the fleece is soft and curly,
made up of long fine hairs
Wool of sheep
acquired from sheep (merino and
rambouillet)
Commercial wool
lanolin (wool grease/wool wax)
a product of cutaneous sebaceous glands
This animal has compound hair follicles with single
primary hair and a group of smaller
secondary hairs
Dog
Animal that has a single hair follicle
Horses and cattle
Animal that has single follicles grouped in clusters
Pig
Animal that has single follicle with primary guard hair
surrounded by clusters of compound
follicles
Cat
hoof pads or bulbs are
comparable to the digital pads of
carnivores
Ruminant
at medial canthus of eye,
larger in rams than in ewes; used for marking
Infraorbital Pouches
– on the midline above the hoofs between the digits of all four feet; used as trail markers
Interdigital Pouches
near the base of the udder or scrotum
Inguinal Pouches
Sebaceous Glands in Farm Animals:
In Goats:
caudal to the base of the horn, secretion is increased during breeding season and
especially pungent in bucks
Horn glands
Sebaceous Glands in Farm Animals:
In goats:
two glands below the tail responsible for the bucks characteristic smell
Sub-caudal glands
Sebaceous Glands in Farm Animals
In Pigs
on the mediopalmar aspect
of the carpus; Produce sexual pheromones,
marking the sow during mating
Carpal Glands
Sebaceous Glands in Farm Animals (pigs)
wart-like skin eminence on the chin; has both tactile and secretory (marking) function
Mental (chin) glands
Sebaceous Glands in Farm Animals (pigs)
in all domestic
species; in the wall of the external auditory
canal; produce “ear wax” which protects
the tympanic membrane from foreign bodies
Ceruminous glands
only in cats; in
the skin around the mouth esp the lower lip;
called “cleaning glands” but functional
significance is probably for marking
Circumoral/perioral glands
secretions mix with
degenerated cells to form a substance
called smegma in horses
Preputial glands
