which is correct: median nerve or medial nerve?

which is correct: median artery or medial artery?
mediaN nerve

mediaN artery
Main drainage of forelimb?
cephalic vein
Main blood supply to carpus/manus?
medial palmar artery
1. provides main innervation to structures of the manus ?

2. divides above carpus into ____ which descend the limb
The median n.

divides above carpus into medial and lateral palmar nerves
Medial and lateral palmar metacarpal nerves are the branches of
Deep branch of the lateral palmar nerve / lateral palmar nerve (With some contribution of ulnar nerve)
Major nerves supplying the palmar aspect of the distal forelimb are
Median nerve and ulnar nerve.
Nerves supplying the dorsal aspect of the distal forelimb (antebrachium and on) are: (name four)
1. Dorsal branch of the ulnar nerve
2. medial cutaneous antebrachial nerve (branch of musculocutaneous n.)
3&4. dorsal branches from medial and lateral palmar (proper) digital nn.
~last couple are only nerves to dorsal aspect of digits
____ descending limb generally overlaps the median n. . in supply to muscles.
But only a little contribution is made to innervation of the manus by way of ________.
ulnar nerve

But only a little contribution is made to innervation of the manus by way of a PALMAR branch.
medial palmar n. descends the forefoot, lying between _____ and _____.
medial palmar n. descends the forefoot, lying between the interosseus muscle and deep flexor tendon.
In middle portion of metacarpus, the medial palmar n. sends a communicating branch obliquely and ventrolaterally to _____.
lateral palmar n.
just above fetlock, medial palmar n. becomes the _______..
just above fetlock, medial palmar n. becomes the *medial (palmar proper) digital n.*

(runs along side of lateral palmar proper digital n. on abaxial side)
Palmar / Plantar digital nerve Anesthesia what nerves blocked?
Medial and lateral palmar/plantar proper digital nn.
Ring (field) block blocks what nerve(s) In the Forelimb?
Plamar/plantar proper digital nerves, and
In the Forelimb :
dorsal branches of the above
Flexors of the carpus and digits innervated by:
Mainly innervated by the MEDIAN and ULNAR nerves.
when/where does axillary a. start?
Subclavian a. becomes axillary a. after subscapular a. splits off
when/where does axillary a. become brachial a.?
axillary a. becomes brachial a. ,,,,after common interosseus a. breaks off
Main artery of the manus (forefoot)
Medial palmar artery
Lateral and medial palmar arteries are the branches of
Median artery – Medial Palmar artery
Lateral palmar – from the deep palmar arch
Lateral and medial palmar metacarpal arteries come from
anastomosis of branch from radial a. and palmar branch of the median a. i.e Deep palmar arch
Lateral and medial palmar proper digital arteries are branches of -------
Medial palmar artery
The nerves to the manus come from the
Median and
Ulnar nerves.
the pulse of the artery can be felt here, especially in
laminitis condition
digital arteries give off dorsal branches to where?
dorsal surfaces of the proximal and middle phalanges.
proper digital aa. pass through the sole foramina into the sole canal, and they anastomose to form
The proper digital aa. pass through sole foramina into sole canal, and they anastomose to form *terminal arch*.
the coronary venous plexus located in the coronary cushion overlying the what?
overlying the common (or long) digital extensor tendon, and abaxial surfaces of the cartilages of the distal phalanx.
This plexus anastomoses with the palmar (plantar) plexus via _____
via foramina in the cartilages.
Digital veins ->_____ -> cephalic v.
palmar v.
Blood vessels in the digital area arranged in the order of what cranially? caudally?
Blood vessels in the digital area arranged in the order of VEIN, cranially, then artery and nerve (VAN).
Median a. gives off what 2 br. proximal to carpus/hock?

What is called after it gives off these two branches?
listed medial to lateral:
1. radial a.
2. palmar branch of median a.

> continues distally as the main artery of the manus (forefoot) - MEDIAL PALMER A.
Where do med./lat. palmar metacarpal a. arise from?
(very complicated)
--basically these form deep branches close to palmar aspect of metacarpal bone, deep to med./lat. palmar arteries
------
* first radial a. and palmar br. of median a. travel deep
* a branch forms between them (deep palmar arch)
* but continue as med./lat. palmar metacarpal a.
* both rejoin medial palmar a. prox. to fetlock
