Anatomy
This structure is the distal most anatomic barrier for the teat
Streak canal or teat sphincter
The term for "endoscopy of the teat"
Theloscopy
Teat laceration
The number of layers required to close the teat
Three Layers
Name 2 complications of any teat/udder surgery (any surgery at all)
Surgical site infection, pain, inflammation, dehiscence
This structure marks the separation between the teat cistern and the gland cistern
Annular ring
This diagnostic test is particularly helpful to evaluate for communication between conjoined teats
Positive contrast radiography
Name 2 interventions for a supernumerary teat
Excise early in life, open the wall between conjoined teats, nothing if so desired
The suture properties desired for internal mammary tissue closure
The name for the proximal aspect of the streak canal
Rosette of Furstenberg
This diagnostic test should be performed despite a negative California Mastitis Test
Bacterial culture of milk
Indication for mastectomy in a cow
Salvage procedure secondary to gangrenous or chronic unresponsive mastitis
Simple interrupted - to prevent stenosis/stricture of the teat
Teat surgery can result in this conformation change resulting in decreased outflow
Stricture or Fibrosis
These are the 2 veins that drain the udder
Cranial epigastric vein
External pudendal vein (secondary)
This diagnostic is most helpful for surgical planning
Ultrasonography
The indication for using a "teat dilator" or "Lichty teat kinfe"
Hard/Slow milker: a cow with a normal udder but teats that are difficult to express milk from
Monocryl because it dissolves in milk
This complication arises from insufficient closure of the mucosa or the teat wall
Fistula formation
These are the 2 arteries that feed the udder
External pudendal artery
Mammary branch of ventral perineal artery (secondary)
Name 2 of the 5 udder abnormalities diagnosable via ultrasound
Fibrosis of the rosette of Furstenberg, Teat wall fibrosis, Mammary gland fibrosis, Verrucose veins, Conjoined teat communication
This is considered a surgical emergency (if you're going to have the best prognosis)
Teat laceration
Name the 5 layers of the teat wall outside to inside
Skin, smooth muscle, conjunctive layer, submucosa, double-layered mucosa
After laceration repair, handmilking should be stopped for at least 10 days because...
The uneven pressure from the hand can cause milk to re-open the wound
