27
Where is the descending doudenum at
The right side
28
Label the following
29
What is Cecotroph
* Night feces
* They eat their night feces to absorb different nutrients than what is found in pellets they produce in the am
* Allows them to get AAs, lipids, etc. that is needed for survival
* Is a normal behavior
30
define coprophagy
feces ingestions
31
Which is cecotropes
The one on the left
32
Label the following:
33
Describe the rabbit female repro system
* Have two cervixes
* Main blood supply is the vaginal a & ovarian a.
* Very delicate duplex uterus
34
Label the following
35
What is the arrow pointing to
Uterine left horn
36
What are the differences in rabbit female repro than small carnivores
* 2 cervices
* Abundant adipose in the broad ligament
* Numerous large vessels in the broad lig
* Lacking a thick suspensory lig
37
What is the arrow pointing to
Ovary of a doe (female rabbit)
38
Label the following
39
Describe the male repro system
* Have a fat bed in the inguinal region ( if damaged or torn can cause herniation of the inguinal canal)
* Very elongated testis found lateral to the penis
* Route of the sperm is the same found in canine & equine
40
Label the following
41
Label the following
42
What are the differences in rat/chinchilla skulls compared to rabbit skulss
* Incisors
* Cheek teeth
* Chinchillas have a huge tympanic bulla & external pinna
* Have hyposdont teeth like seen in rabbits & equine; are prone to patho on their teeth too
* Single incisor in ea quadrant
* Rostral surface of the teeth has thicker enamel than the enamel on the lateral/caudal surface (also causes weird shape b/c of uneven wear)
43
Label the following:
44
Label the following
45
Label the following
46
Who has elodont & hypsodont teeth
* Chinchillas
* Guinea pig
47
Define elodont
Incisor teeth that are continuously growing through the life of the mammal
48
Define hypsodont
High crowns to teeth; irregular occlusal surfaces, enamel crests & dentinal grooves, cheek teeth, & both premolars & molars
49
What is the arrows pointing to
Elodont teeth
50
Which teeth are elodont in rabbits & rodents
The incisors
51
What is harder enamel or dentin? Why is this important
Enamel b/c it is thicker & does not wear down as fast as dentin does
52
What teeth are found in gerbils, hamsters, mice, & rats
* Anelodont
* Elodont
* Brachyodont
53
What are anelodont teeth
* Pre molars & molars
* Are rooted but they do not grow throughout life
54
What are brachyodont teeth
* Low crowns seen on the teeth
* Premolars & molars
* Enamel over entire occlusal surfaces
55
What is the arrow point to
Anelodont & brachyodont teeth
56
Describe hypsodont teeth
* High crowns to teeth
* Irregular occlusal surfaces
* Enamel crests & dentinal grooves
* Cheek teeth
* Are both premolars & molars
57
Why do rodents have a white enamel on their incisors while rabbits have a orange/yellow tinge to them
B/c the enamel on the rats incisors is much thinner than the enamel found on rabbits incisors
58
Describe the digestive system of rodents:
* Simple
* Not fermenters
* Single chamber stomach

* Have a omnivorous type of digestive system
59

Label the following
65
Label the following
66

68
Label the following
69
Label the following
70
Label the following
71
How many mammary glands do rats have
* 6 pairs of mammary glands
* 12 glands total
72
Label the following
73
What needs to occur in guinea pigs for parturition
* Needs to occur young in life
* Pubic symphysis ligaments open prior to delivery of large feti
* If sow has litter before fusion of the pubic symphysis then cartilage union forms & persists for life
* Cartilage union expands to allow passage of larger feti
* Need to have their first litter by 9 months
74
Label the following
75
Describe dystocias in guinea pigs & chinchilla
* Precocious & large feti
* If sow doesn't have a litter prior to fusion of pubic symphysis by 6 to 9 moths dystocia will be common
* If they don't have at least one litter before 9 months the pelvic symphysis will ossify making parturition difficult
