How many bones do horses have?

52
110
205
Most horses have 205 bones, although some breeds – such as the Arabian – may have one fewer vertebrae and one less pair of ribs. There are 54 bones in the vertebral column, 40 bones in each leg, 36 ribs, 34 bones in the skull, and one sternum.
425

Which of these is NOT a bone?

Ileum
The ileum is the third segment of the small intestine while the ilium is one of three pelvic bones (to help remember which is which, think of “ilium” and “hip” both having an “i.”)
Manubrium
Xphiod
Ethmoid

The “withers” are made up of long, thin bones extending up from the thoracic vertebrae.

True
You and your saddle are sitting on a series of bony spikes that originate from thoracic vertebrae. Also known as dorsal spinous processes, when these long, thin bones override or impinge on one another it’s called “kissing spine.”
False

Name the two bones within the hoof: _______________________________ and ___________________________

Click here to find out if you knew the answer!
The larger bone in the hoof, the coffin bone, is the third phalanx or digit and is also called P3. The smaller bone in the hoof is actually the distal sesamoid and goes by the common name navicular bone.

Do horses have a clavicle (collarbone)?

Yes
No
Horses do not have a clavicle or collarbone. This means their fore limbs are not directly attached to the spinal column like the hind limbs but instead are suspended by soft tissues (muscles, tendons, ligaments). This arrangement is referred to as the “thoracic sling.”

Which has more bones in the horse, the knee or the hock?

Knee
The knee or carpus joint has 7-8 bones while the hock or tarsus joint only has 6 bones. The knee of the horse is equivalent to the wrist of a human while the hock is comparable to the human ankle.
Hock

If ligaments attach bone to bone, then tendons attach bone to___________________________?

Tendons attach bone to muscle and are what enables us to move as muscles contract and pull on bones. Ligaments attach bone to bone, serving to hold joints together, stabilizing them.

Put these minerals in order from highest to lowest concentration in bones: phosphorus, calcium, and magnesium.

Calcium makes up about 35% of equine bone followed by Phosphorus at 14 to 17%. Magnesium is the third most abundant mineral within bones.

Sunlight
Genetics
Proper nutrition
The two prime elements involved in the production of strong bones are the correct kind of exercise and nutrition. Appropriate exercise provides mechanical stress on the bone resulting in new bone being laid down as long as the nutritional building blocks are available in the sufficient quantities and ratios.

Bone is the only tissue capable of entirely reconstituting itself.

True
Bones are themselves living structures with a generous blood supply and a sophisticated remodeling process that continues during the lifespan of the animal. Not unlike road construction where a section of pavement is torn up and then replaced, osteoCLASTS dissolve damaged bone while osteoBLASTS fill in the area with new material.
