Bursa and Tendonsheets in Equine FL and HL

Question 1

Tendon sheets

Answer 1

= Vagina Tendinis
Tendon sheets:
- Thin Walled
- Double layered
- Fluid filled

Function:
Protection of tendons

Main tendonsheets eq:
FL= 3
1. TS of M.ex.dig.communis
-> Vaginalis tendinis M. extensorius digit communis

2. Proximal
   - > Vaginalis synovialis communis mm flexorum proximalis
3. Distal
   - > Vaginalis synovialis communis mm flexorum Distalis

HL=4

Question 2

Bursa

Answer 2

= Small fluid filled (synovial) sac
-> In places of friction to avioid it
FUNCTOIN:
- Faciliate Grinding of skin, muscle or tendon.

TYPES:

• Sub muscular
• Sub tendinous
• Sub ligamentous
• Sub fascial
• Sub cutaneous

Question 3

MAIN BURSA´S on the FL

Answer 3

(*6 main ones)

1. BURSA Subtendinea M. infraspinati
   - Tendon of M. Infraspinati –> caudal end of Tub. Major
2. BURSA Intertubercularis (Bicipitalis)
   - Underlies biceps brachii tendon btw Tub major/minor.
   - Inflamation —> Shoulder lameness.
3. BURSA Subtendinea M.Brachialis
   - Btw insertion tendon of Brachialis –> Radius.
4. BURSA Subtendinea M. Tricipitis Brachii
   - btw tendon of triceps-> Olecranon
5. BURSA Musculi extensor digitorum communis
6. BURSA Podotrochlearis (Navicularis)
   - -> Frictionless movemts btw Deep dig. flex and dist SB.
