the paw Flashcards
digitigrade
Only distal end of metacarpals/ metatarsals and digits in contact with ground
3 pads
digital
metacarpsal/ metatarsal
carpal (no tarsal pad)
Digital pads
- Digit 1 not in contact with ground
- Digit 2-5 touch ground
- Pad is under distal interphalangeal joint
metacarpal/ metatarsal pad
- Large
- Under MC/ MT - phalangeal joints
- Main weight bearing pad
Carpal pad
- Forelimb only
- Under carpo-metacarpal joint
- May contact ground while sprinting
- Subcutaneous fibro-elastic tissue
- Fat pad
- Sweat glands (dogs don’t have sweat gland over body but do on pads)
- See homologies between pads of different animals
pads are
thick, tough, densely cornfield skin
Carpal pad function
Absorb shock
Axis runs between
digits 3 and 4
Axial
Axial; near to axis
Abaxial;
Abaxial; away from axis
On palmar side of forepaw we have which artery
median
median artery in paw goes through _______ and breaks into multiple arteries:
carpal canal
common digital arteries (there are palmar and dorsal common digital arteries)
_______ are deep to the common digital arteries
Metacarpal arteries (also have dorsal and palmar pairs)
the common digital arteries Divide at start
of digits and become proper digital arteries and go down axial and abaxial side of each digit
how to name arteries at the MC/ MT level
it goes from top to bottom:
dorsal common digital arteries
dorsal metacarpal arteries
palmar metacarpal arteries
palmar common digital arteries
groups of 4 inbetween each of the digits
