There are two metacarpal bones in ox and they are small metacarpal and large metacarpal bone. You will find variation in number of metacarpal bone in different animals.
Hello, welcome back and thanks for getting into this article at anatomy learner. If you are looking for the complete anatomy of metacarpal bone of ox then this article is going to be best guide for you.
Fine, in this article I am going to share the most important osteological features from metacarpal bone of ox. I will also show you the main important osteological features that differ from the metacarpal bones of ox.
After completing this article you will able to identify the different osteological features from metacarpal bone of ox. You will also able to differentiate metacarpal bone from metatarsal bones of ox.
Here in this article I will also share some information about the metacarpal bone of other species like horse, dog and pig.
So if you are interest to learn the anatomy of metacarpal bone of different animals then you might continue this article.
Metacarpal bone of ox
Here I am going to enlist the important anatomical structure from metacarpal bone of ox. You should identify these structures from the metacarpal bone of ox.
#1. Large and small metacarpal bones of ox
#2. Shaft of metacarpal of ox
#3. Dorsal and palmar surface of metacarpal of ox
#4. Dorsal vertical groove on metacarpal of ox
#5. Two foramina (proximal and distal) at dorsal vertical groove of metacarpal in ox
#6. Articular surface at proximal extremity of metacarpal in ox
#7. Metacarpal tuberosity at proximal end of metacarpal in ox
#8. Inter-condyloid cleft in distal extremity of ox metacarpal
#9. Four facets at palmar aspect of metacarpal of ox
Hope you will able to find out all these structures from the metacarpal labeled picture of ox.
Details anatomy of metacarpal bone of ox
You know the metacarpal bone of ox consists – the larger metacarpal bone (III and IV) and lateral small metacarpal bone (V). The larger metacarpal bone in ox, also known as the cannon bone in animal.
You will find the shaft or body and two extremities in metacarpal of ox. The shaft or body of metacarpal of ox is irregular cylindrical in shaped. Body of metacarpal presents two surfaces and two borders in ox.
The dorsal surface of metacarpal body of ox is convex and smooth in appearance. You will find a vertical groove at the dorsal surface of ox metacarpal. This vertical groove also known as longitudinal groove of metacarpal. Again, there are two foramina present at the dorsal vertical groove – proximal foramina and distal foramina. The palmar surface of metacarpal of ox is flat and have vertical groove with foramina.
In the proximal extremity of metacarpal bone of ox, you will find two important structures – articular surface and metacarpal tuberosity. The lateral articular surface is small and the medial articular surface is larger in metacarpal of ox. Again the metacarpal tuberosity is located at the dorso-medial surface of metacarpal (proximal end).
In distal extremity you will find the lateral and medial condyle in metacarpal bones of ox. The space between lateral and medial condyles is known as inter-condyloid cleft of metacarpal. Again, in each condyle you will find two articular areas which are divided by ridge.
In posterior aspect of distal extremity of ox metacarpal, there are four depressions for accommodation of proximal sesamoid bones.
The small metacarpal bone of ox is a small elongated pieces of bone at postero-lateral aspect of large metacarpal bone.
Metatarsal bone of ox
There are also two metatarsal bone of ox – large metatarsal (III, IV) and small metatarsal bone (II). These metatarsal bones are compressed transversely and four sided in ox. The dorsal vertical or longitudinal groove is deep and wide in ox.
The planter surface of large metatarsal bone of ox is marked by variable grooves and bears proximal foramen.
Difference between metacarpal and metatarsal bone in ox
The length of metatarsal bone is more than the metacarpal bone (about one seventh longer than metacarpal in runimnant and one-sixth longer than metacarpal in horse)
Metatarsal bone compressed transversely and distinctly four sided in animals. In metatarsal bone of ox, the dorsal longitudinal groove is deep and wide.
Again, in metatarsal bone, the medio-planter angle of proximal end bears facet for articulation with small metatarsal bone in animals.
Metacarpal bone of horse
In horse, you will find one large metacarpal (IiI) and two small metacarpal bones (II and IV). The large metacarpal bone in horse also known as the splint bone. The nutrient foramen present in the junction of proximal and distal third of the horse metacarpal bone. Again, the metacarpal tuberosity in horse metacarpal is prominent.
Metacarpal in dog
You will find five separated metacarpal bones in dog; III and IV are larger. The II and IV metacarpal are almost of equal in length.
Metacarpal of pig
There are four metacarpal bones found in pig. The first metacarpal is absent and second, fifth are small in pig.
Digits and phalanges in ox
There are two developed (III and IV) digits found in ox anatomy. The II and V digits are rudiment (known as dew claws) in ox anatomy. Each of these digits contains three phalanges – proximal, middle and distal phalange

As I used to update the different labeled images (like metacarpal or metatarsal bone of ox) there in a regular basis.
Hope you got an idea about the most important osteological features of metacarpal bone of ox. Now you will able to identify the osteological features from metacarpal of ox. Hope, you also learn how you will differentiate the metacarpal bone from the metatarsal bone of ox.
