Where do the superficial cervical lnn. in the horse drain to?
Efferent vessels enter caudal deep cervical lnn. (some may enter jugular v.)
Where do the axillary lnn. in the horse drain to?
Efferent vessels course to caudal deep cervical lymph nodes
Where do the cubital lnn. in the horse drain to?
Efferent vessels course to axillary lymph nodes
Where do the superficial cervical lnn. in the ox drain to?
Efferent vessels drain to tracheal trunk or thoracic duct
Where do the axillary lnn. in the ox drain to?
Efferent vessels course to the axillary lymph nodes of first rib, caudal deep cervical lnn. or jugular v.
Where do the cubital lnn. in the ox drain to?
Efferent vessels course to the axillary lymph nodes of first rib, caudal deep cervical lnn. or jugular v.
What are the branches off of axillary a. in the horse?
External thoracic a.
Suprascapular a.
Subscapular a.
-Thoracodorsal a.
-Caudal circumflex humeral a.
What are the branches off of brachial a. in the horse?
Cranial circumflex humeral a.
Deep brachial a.
Bicipital a.
Collateral ulnar a.
Transverse cubital a.
Common interosseous a
What are the branches off of median a. in the horse?
Median a. (15)
Deep antebrachial a. (16)
Proximal radial a. (17)
Radial a. (18)
-Deep palmar br. (19) contributes to the deep palmar arch
Palmar br. (20)
-Deep br. joins radial a. to form the deep palmar arch
-Superficial br. rarely developed – contributes to superficial palmar arch
Medial palmar a. (21)
-Continuation of median a. after radial a. and palmar br.
-Gives rise to medial and lateral palmar digital aa.
What forms the deep palmar arch in the horse and what does it give rise to?
Formed by deep br. of palmar branch of median a. and deep palmar br. of radial a (also off of median a).

Gives rise to medial and lateral palmar metacarpal II and III aa. which course deep to interosseus and then unite distally and join the lateral palmar digital a.
What is the main blood supply of the distal thoracic limb in the horse? What is this artery a continuation of?
Medial palmar a is main blood supply to distal part of the limb. This artery is an extension of the palmar br off of median a.

This is important to know.
What does the medial palmar a. in the horse thoracic limb branch into? What is their clinical significance?
Branch into the medial and lateral palmar digital a. You can take the pulse here.
What is the blood supply to PI of the horse thoracic limb?
Dorsal and palmar brs of palmar digital a.
What is the blood supply to coronary corium of the horse thoracic limb?
Dorsal and palmar branches to PII from palmar digital aa
What is the blood supply to laminar corium of the horse thoracic limb?
Dorsal br. to PIII
Through alar foramen to supply laminar corium
What is the structure through with the terminal arch supplies PIII in the equine thoracic limb?
Sole foramina
When you hear metacarpal something do you think deep or superficial?

What means the opposite?
metacarpal - deep

Common - superficial
Where does the cephalic v end?
External jugular v.
What are the veins of the proximal thoracic limb in the horse?

Which is the most important?
Axillary v. (1)
-Suprascapular v. (2)
-Subscapular v. (3)
--Caudal circumflex humeral v. (4)
--Thoracodorsal vv. (6, 6’, 6”)
---Superficial thoracic v. (7)

Brachial vv. (8, 8’)
-Deep brachial v. (9)

Cephalic v. (11, 12) (most important)

Median cubital v. (13)
-Joins cephalic and brachial vv
Where is the palmar venous plexus?
In sole corium, around toe, between sole and digital cushion
What is the plexus of the laminar corium of the equine hoof?
Dorsal venous plexus
What is the plexus at the coronet in the equine hoof? Where does it drain? What is the significance?
Coronary venous plexus
At coronet – in coronary and perioplic corium
Drains into digital veins
Cuts at coronet bleed
What are the arteries coming from axillary a. in the ruminant?
Axillary a. (1.)
-External thoracic a.
-Suprascapular a. (ox) (2.)
-Subscapular a. (3.)
--Thoracodorsal a. (5.)
--Caudal circumflex humeral a. (8.)
What are the arteries branching off of brachial a. in the ruminant?
Brachial a. (6.)
-Cranial circumflex humeral a. (7.)
-Deep brachial a. (9.)
-Bicipital a.
-Collateral ulnar a. (11.)
-Transverse cubital a. (10.)
-Common interosseous a. (13)
In the ruminant, suprascapular comes from axillary a, where does it come from in the small ruminant?
suprascap comes from superficial cervical a. of subclavian a
What are the branches off of median a. in the thoracic limb of the ruminant?

What does median a. become?
Median a. (7)
-Deep antebrachial a.
-Radial a. (8)

Becomes: Palmar common digital a. III (9)
What are the veins of the ruminant thoracic limb?
Axillary v.
