LA Prosection Flashcards
How does the Scapula of horse compare to carnivores?
- more triangular shape
- tuber spine present
- acromion process is absent
- supraglenoid tubercle is larger and further from the glenoid cavity
How does the humerus of horse compare to carnivores?
Shorter, wider and more robust
Horse has an intermediate tubercle in the tubercular groove
Which tubercle of the humerus makes up the ‘point of shoulder’ a palpable landmark? l
Lateral/Greater
A groove spirals over the lateral aspect of the humerus. What muscle sits in this
groove?
Brachialis
What are the differences between the radius and ulna in the horse and ox?
Ox - radius and ulna are fused
Horse - only the upper end of the ulna remains distinct
How many carpal bones are there in the equine carpus?
7
Which metacarpal bones are present in the equine distal limb? Which are weight bearing?
2 and 4 are splint bones
MC3 is weight bearing
How would you describe the coronary band?
The junction between the skin and the hoof
Which parts the hoof are in contact with the ground?
Frog
Distal edges of the hoof wall
How would you describe the microscopic divisions of the sensitive laminae in
Horse and ruminants?
- Horses have primary and secondary sensitive laminae
- Ruminants only have primary sensitive laminae
What is the ‘white line’?
The junction between the sole and the wall
Bovine – Which digit is larger in the forelimb?
Lateral - more weight bearing
Overgrowth is a common cause of bovine lameness. Trimming must occur regularly to prevent
overextension of which joint and therefore tension of which tendon insertion?
Coffin
DDFT
Where does the common digital extensor tendon insert onto?
Limited attachments onto P1 and P2, before receiving the extensor branches of the
interosseus (suspensory) ligament and ending on P3
At which level does the SDFT form a sleeve around the DDFT?
At the level of the proximal sesamoid bones (metacarpophalangeal joint)
