5. Scapula Of Horse Scapularspine Little Further Backword To Anterrior Border Spine (1:3) Subscapularfossa Is Deeper And Well Marked Tuber Scapulae Is Further Away From Glenoid Cavity Corocoid Process Is Better Devloped Acromion Process Is Absent Nutrient Foramen Is Placed At Distal Third Of Infraspinous Fossa

7. Scapula Of Pig Spine (1:0.8) Spine Is Wide And Further Backward Glenoid Notch Is Absent (Cavity Is Rounded) Corocoid Process Is Absent Acromion Process Is Rudimentary Scapular Cartilage Is Not Extensive

8. Scapula Of Fowl Scapula Is Narrow, Thin Elogated And Flate Long Bone Situated Parallel To The Vertibral Colum It Present Pneumatic Foramean Near Acromian Process

9. Humerus Long Bone Downward Backward Between Shoulder Joint And Elbo Joint Shaft And Two Exteremties 4surface (Lateral, medial, anterior, posterior) 2ends( proximal,distal )

10. Cattle Humerus Twisted Shaft Anterior Surface Is Triangular Wide And Smooth Proximally And Narrow , Rough Distally Posterior Surface Rounded , At Middle Of Distal Third Nutrient Foramen Present Medial Surface Teres Tubercle Lateral Surface Muscular Spiral Groove , Deltoid Ridgh , Deltoid Tuberosity Proximal End :- Head , Neck , L- tuberosity (Large),m- tuberosity (Small), Bispital Groove Distal End :- 2 Condyles And 2 Epicodyles ( L And M) , Coronoid Fossa , Olecranon Fossa , Olecranon Process

11. Humerus Of Horse Deloid Tuberosity Is More Prominent Biciptalgroove Divided By Ridge Olecranon And Coronoid Fossa Are Shallower L-m Tuberosities Are More Prominent Nutrient Foramen Placed At Distal Third Of Medial Surface

12. Humerus Of Pig Teres Tubercle Is Absent Condyles Are Equal Size Shaft Is Laterally Compressed And Flat On Medial Side Muscular Spiral Groove Is Shallow Deltoid Tuberosity Is Small Coronoid Fossa Is More Prominent

13. Humerus Of Dog Musculospiral Groove Is Shallow L- tuberosity Is Undivided Deltoid Tuberosity Is In The Form Of Ridge Coronoid And Olecranon Fossa Communicate With Each Other Through Large Supra- trochlear Foramen Humerus Of Fowl Bone Directed Parallel To Thorasic Vertebre When Wing Is At Rest Proximal End Present On Medial Aspect , Opening Leading Into Air Cavity In Its Shaft

14. Radius And Unla Radius:- Large Bone Situted At Vertical Direction Forms Elbo Joint With Humerus Above And Carpal Joint With Carpal Bones Below Unla :-long Bone Fused With Radius Anterior Surface Is Fused With Posteriolateral Aspect Of Radius

15. Radius And Unla Cattle Proximal End Of Unla :- Olecranon Process, Anconeous Process Semilunar Notch Radius:- Coronoid Process , Radial Tuberosity Proximal Interosseous Space Distal Interosseous Space Styloid Process Carpel Facet

16. Radius And Unla Horse Unla Of Horse Is Less Developed And Shorter Than Ox Radial Tuberosity Is More Prominent Distal Iterossesous Gape Absent Semilunar Notch Is More Extensive Radius And Unla Pig Radius is comparatively thin and short Unla is massive and curved backward Interosseous space is very narrow due to very close of both bone

17. Radius And Unla Dog They are two separate bone in contacts of two ends Interosseous spae is narrow and extended through length of bone Small tubercles present near olecranon process Radius And Unla Fowl Unla Is Comparatively Massive Both Bones Are Contact At Two Ends Introsseous Space Is Wide Semilunar Notch Is Not Well Marked

18. carpals Six short bone arranged in two row between radius and unla Proximal row:- radial , intermediate , unla , accessory Distal row:- 1,2,3,4 carpal Cattle:-6 Horse:-7 Dog:-7 Pig:-8 Fowl:-2

19. Cattle Metacarpal 2 Metacarpal Bones In Cattle Large Metacarpal And Small Metacarpal Large Meta Carpal:- (Canon Bone) It Represents 3 And 4 Metacarpal Shaft Is Irregularly Cylindrical Two Surface (A ,P) Anterior Surface :- 2 Foramen Present Proximal And Distal Posterior Surface:-vertical Groove And Two Foramen Present For Sesamoidbone Proximal End :- 2 Articular Facet Tuberosity Present At Anteriomedial Aspect Distal End :-Divided By Cleft Into 2 Condyle Each Condyle Divided By Ridge

20. Horse Metacarpal 1 large metacarpal and 2 small metacarpal Largemetacarpal :- vacular groove absent Medial condyle of articular area for 1 phalanx is slightly larger than lateral Pig Metacarpal 4 bones 1 st is absent 3 rd and 4 th are large and carry chief digits 2 nd and 5 th are much smaller and bear accessory digits

21. DOG Metacarpal FOWL Metacarpal 5 Bones 1 st Is Shortest 3 rd And 4 th Are Longest 2 nd Is Longer Than 5 th Matacarpus includes 3 bony elements it fuse with distal row of carpal it known as carpo metacarpus

22. Phalanges Cattle Double Digit 3 Phalanges 1 st Phalanx (Long Bone) Placed Downward Forward Between Large Meta Carpal Above And 2 nd Phalanx Below , 2 Facet For Sesamoid Bone 2 nd Phalanx Placed Between 1 And 3 Phalanges (Long Bone) 3 rd Phalanx (Short Bone) 4 Surface And 1 Angel Between 2 nd And 3 rd Phalanges Small Facet For Distal Sesamoid Bone

23. Horse Phalanges Single digit 3 phalanges 1 st phalanx present v shape area 2 nd is short and wide 3 rd phalanx has 3surface 3 border and 2 angel Pig Phalanges Each Digit Has 3 Phalanges 3 rd And 4 th Well Developed 2 nd And 5 th Digit Are Small

24. Dog Phalanges 5 Digit 3 rd And 4 th Longest 1 st Phalanx Is Chief Digit Have 4side Shaft 3 rd Phalanx Correspond To Shape Of Calws Fowl Phalanges 3digit 1 st And 3 rd Have 2 Phalanges 2 nd Have Only One Sesamoid Bone Absent

25. Sesamoid Bone Cattle :-(6) Proximal 2 Each Digit Distal 1 Each Digit Horse:-(3) Proximal 2 Distal 1 Pig:-(12) 4metacarpal × 2 Foramen=8 4phalanges=4 Dog:-(14) Proximal-(9)(posterior) 1 st Digit =1 2 nd 3 rd 4 th 5 th Digit=8 Distal-(5)(anterior)
