57
Where most animals have intercostal arteries, birds have...
Intersegmental Arteries
59
Which nerve is found between the middle and caudal liver sector?

Yes
61
The bird cerebrum lacks...
Gyri
62
Which part of the brain is well developed in birds?
Cerebellum
## Footnote
*in order to control flight*
63

Complete decussation
## Footnote
*Mammals have semi-decussation*
64
Describe the avian medulla spinalis
* Similar to mammals until S1
* At S2 , canalis centralis travels dorsally
* to the substantia grisea
* It is encapsulated by corpus gelatinosa
65
Avian brachial plexus is divided into...
* Fasciculus dorsalis → Extensor muscles
* Fasciculus ventralis → Flexor muscles
66
Why can kidney stones cause limping in birds?
* The kidney is adjacent to the ischiadic nerve
* Stones cause pressure on the nerve and therefore pain
67
Marek's disease
* α-herpes virus
* Causes enlargement of the ischiadic nerve
