-Assist with thermoregulation and keeping animals dry and clean
-Examples: bristles on a pig, horse mane, cow tail, featherings on legs and tail of dogs
Wool Hair - answers✔✔-Thin, wavy and usually shorter than guard hairs
-Creates a soft undercoat under the guard hairs
-Examples: sheep, angora and cashmere goats, angora rabbits, and aplacas
Tactile Hair - answers✔✔-Very thick and much taller than surrounding guard hairs
-Follicles are very deep in subcutis - sometimes even into underlying muscle
-Most often on the face
-Example: cat whiskers
Subcutis - answers✔✔-Deep to the dermis
-Made up of very loose connective tissue and fat
-Different depending on the species
-Often used to determine dehydration in animals
Footpads - answers✔✔-The cushions that animals walk on
-Often covered by a very thick hairless epidermal layer
-Dogs and cats: only digital and metacarpal pads are functional (bonus pad: carpal pad, on forelimb)
-Herbivores (digital pads, bulb-ruminants and pigs, frog-horse)
Claws (carnivores) - answers✔✔-Similar to the nail of a primate but more compressed into a sharp

Hooves (equine) - answers✔✔-Curved walls (bars, heels, quarters, toe)
-Weight is distributed along the wall on the frog
-Sole: between the frog and the wall
-White line is where the wall and sole meet
-Periople is the band of soft tissue that covers the most proximal surface of the hoof wall where it
joins the skin
Lamellae/Laminae - answers✔✔-Interdigitations between the dermis and epidermis keeping the
nail/hoof on the digit
-More pronounced and important in horses
Hooves (ruminants and swine) - answers✔✔-Similar to the horse in that there is a wall and both
epidermal and dermal laminae/lamellae but:
-They walk on two digits
-There is a much smaller sole
-The footpad is much larger and softer
-The laminae are less developed
Horns - answers✔✔-Have a bony base that is an extension of the frontal bone of the skull (frontal
sinus extends into it)
-Dermis is tightly adhered to the bony origin
-The horn tissue itself is produced by the epidermis
-NOT antlers (permanent, grow continuously and in both females and males)
What is a bone? - answers✔✔-Major skeletal tissue
-Contains Ca, P, other minerals
-Bone is living tissue
-Ways to classify: location and shape
Axial - answers✔✔-Trunk
