Answer 1

Correct Answer - Option 3 : 4

A saddle joint is a synovial joint where one of the bones forming the joint is shaped like a saddle with the other bone resting on it like a rider on a horse. Saddle joints provide stability to the bones.

 

Fibrous Joints:-

• These joints are also called fixed or immovable joints because they do not move.
• They are joined by dense irregular connective tissue that is rich in collagen fibers. These joints have no cavity.
• These joints include:-
  • Bone of Forearm
  • Leg

Ball and Socket Joint:-

• These joints are a type of synovial joint where the spheroid articular surface of one bone sits within a cup-like depression of another bone.
  • These joints include:- 
  • Glenohumeral Joint 
  • Hip Joint

Malleus Joint:-

• This joint is also called the incudomellear joint, is the joint between the incus and the malleus.
• The joint's function is to transfer vibrations between the ossicles in the middle ear, which is perceived as sound.
