CH 10 Integumentary System (nails, claws, hooves) Flashcards
1
Q
Wall
A
- epidermal tissue that includes the toe (front), quarters (sides), and heels (back)
- usually located dorsal and lateral to the distal phalanx
2
Q
Sole
A
- softer hoof tissue located on the on the ventral surface of the hoof (bottom of the hand)
- located ventral to the distal phalanx and is usually flakey
3
Q
Tori
A
- aka footpads
- provide cushioning and protection for the bones of the foot
- thick and composed of keratinized epithelium
4
Q
The subcutaneous layer of the tori contains
A
- many adipose cells
- elastic connective tissue
- sweat glands are also found in most mammalian foot pads
5
Q
Digital pads
A
-Dogs and cats have these on the palmar and plantar surfaces of the phalanges
6
Q
Metacarpal and metatarsal pads
A
singular pads located on the palmar and plantar surface of the metacarpal/metatarsal area
7
Q
Carpal pads
A
- located on the palmar surface of each carpus
- do not bear weight when the animal is standing
8
Q
Digitigrade
A
- animals that walk on their toes
- only the digital and metacarpal/metatarsal pads making contact with the ground
9
Q
Plantigrade
A
- footpads as those in primates
- animals walk with phalanges, metacarpals/metatarsals, and carpal/tarsal bones making contact with the ground
10
Q
Coronary band (of the horse)
A
- region where hoof meets the skin
- analgous to the cuticle of the human nail
- site of coronet growth
11
Q
Peripole (of the horse)
A
- flakey tissue band located at junction of the coronary band and the hoof wall and extends distally
- widens at the heel to cover the bulbs of the heels
12
Q
Quick
A
- tissue in the claw that contains numerous blood vessels and nerve endings
13
Q
Quicking
A
- trimming the nail or claw to the level of the dermis
- results in bleeding and pain
14
Q
Claw and hoof combining forms
A
claw - onych/o
hoof - ungul/o
15
Q
Corium
A
the dermis to the hoof
- located under the epidermal surface of the hoof wall, sole, and frog
- corresponds to the quick
