|
What cavity is present at distal end of scapula ?
|
glenoid cavity
|
|
What is absent from scapula of horse?
|
absence of the acromion in scapula, also no acromion head of deltoideus m.
|
|
Head of the humerus - ____ than glenoid cavity, and therefore, affords a ___ movement.
|
Head of the humerus - larger than glenoid cavity, and therefore, affords a gliding movement.
|
|
present between the tendon of origin of the biceps brachii m. @ joint cavity?
|
Interposed intertubercular bursa
(tendon is mostly fibrocartilaginous) and the joint capsule. |
|
tendons of which of these muscles does NOT stabilize shoulder joint?
supraspinatus, teres major, infraspinatus, subscapularis, teres minor and biceps brachii muscles |
teres major m. is NOT involved
others stabilize this joint as they pass over and attach close to it. |
|
Main mov't of shoulder joint?
|
Mostly flexion and extension. Some abduction, adduction and rotation permissible
|
|
Shoulder is normally flexed at what angle?
Therefore it helps in what aspect? |
Joint normally partially flexed (115 degrees), hence provides an excellent anti-concussion mechanism in the forelimb
|
|
Another name of elbow joint?
What type of joint is this? |
CUBITAL
Compound Synovial, hinge (ginglymus) |
|
The forelimb bears ____ of the body weight?
|
between 55% and 60%
|
|
About 95% of the lameness problems are said to occur where?
|
below the carpus.
|
|
Bones present in elbow?
|
Distal end of humerus (condyle), the fovea capitis of head of radius and the trochlear notch of the ulna.
|
|
Where does common digital extensor insert?
|
P3
|
|
Where does DDF insert?
|
P3
|
|
Where does SDF insert?
(edit response) |
bunch of places, it forks over DDF creating manica flexoria
(edit response) |
|
Pastern joint
Coffin joint |
PIP
DIP |
|
_____ ligament also, along with _____tendon, prevents buckling forward of pastern joint when foot hits the ground.
|
Oblique Sesamoiden ligament along with SDF tendon prevents buckling FORWARD of pastern joint (PIP) when foot hits ground.
|
|
thought to be distal continuations of the interosseus muscle.
|
The distal sesamoidean ligaments
|
|
two bands of fibres, crossing each other, from bases of sesamoids to opposite eminence on proximal end of first phalanx.
|
the deep (or cruciate) sesamoidean ligament
assist interosseus muscle in support of the fetlock joint. |
|
Two ligaments running from axial sides of the bases of sesamoid bone to the abaxial side of eminence of the proximal phalanx.
|
Short sesamoidean ligaments
|
|
extends from the sesamoid bones and intersesamoidean ligament to fibrocartilage lip on palmar aspect of proximal end of middle (2nd) phalanx. Straight fibres;
long. |
superficial (straight) sesamoidean ligament:
|
|
formerly suspensory ligament; also known as the superior sesamoidean ligament
|
The interosseus muscle : little muscle in the foal, and entirely tendinous in the adult horse. Well formed, |
|
Where does interosseus muscle aka suspensory ligament insert?
|
Divides/forks at distal 1/4 of cannon bone into two
Each division inserts on abaxial surface of each proximal sesamoid bone another pair of branches comes off and goes dorsally to dorsal surface of proximal phalanx. |
|
what are dorsal branches of interosseus muscles called?
where does it go? |
<extensor slip> to the common digital extensor tendon over dorsal surface of proximal phalanx.
|
|
support of the fetlock,
preventing over-extension (dorsal flexion) of the joint when foot on the ground the dorsal branch limits flexion of the joint, and prevents deep flexor tendon from flexing the joint as a result of tension on it (deep flexor), when limb is on the ground and joint is extended. |
functions of extensor slip
|
|
extends from the bases of the sesamoid bones to palmar surface of proximal phalanx.
|
middle (or oblique) sesamoidean ligament
|
|
hardest worked joint in forelimb?
most often injured (more stressed)? |
hock/carpus
1st: fetlock joint 2nd: coffin joint (DIP) |
|
what do proximal sesamoid bones articulate with?
|
only distal end of canon (MC3)
|
|
what connects navicular bone to P3?
|
distal sesamoidean impar (navicular) ligament
|
|
"cry first"
|
Fracture of the proximal sesamoid bone(s)
|
|
What are the ligaments of the fetlock joint?
|
Collateral ligaments (deep and superficial)
Collateral sesamoidean ligaments |
