What are the three types of joints found in the horse’s body?

Horses have three types of joints:

• Fibrous joints. These joints don’t allow for any movement at all (such as the joints between the bones in your horse’s skull).
• Cartilaginous joints. These joints are connected by cartilage and allow for limited movement (such as the joints in your horse’s backbone).
• Synovial joints.

Is the elbow joint a saddle joint?

Hinge joints: These joints only permit flexion and extension and are also uniaxial. An example of this type of joint is the elbow joint. Saddle joints: These joints are as the name suggests shaped like a saddle, and permit movement in two separate planes and are termed biaxial joints.

Which of the 3 joints in the elbow the main elbow joint and is a hinge joint which permits flexion and extension to occur?

The humeroulnar and the humeroradial joints are the joints that give the elbow its characteristic hinge like properties. The rounded surfaces of the trochlea and capitulum of the humerus rotate against the concave surfaces of the trochlear notch of the ulna and head of the radius.

What are the 3 elbow ligaments?
