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 |
