ANATOMY

Detailed explanation-1: -So, the correct answer is ‘Saddle joint ’.

Detailed explanation-2: -Metacarpophalangeal Joint (MP) The MP joint is where the hand bone, called the metacarpal, meets the finger bones, called the phalanges. A single finger bone is called a phalanx.

Detailed explanation-3: -Examples of saddle joints in the human body include the carpometacarpal joint of the thumb, the sternoclavicular joint of the thorax, the incudomalleolar joint of the middle ear, and the calcaneocuboid joint of the heel.

Detailed explanation-4: -It connects the trapezium and the metacarpal bone of your thumb. The flexion-extension and abduction-adduction characteristics of this joint allow your thumb to spread out wide to help grasp large objects, while also allowing it to move inward, to tightly touch each of your other fingers.

Detailed explanation-5: -Synovial: Condyloid This type of joint is biaxial because it permits two axes of movement: flexion/extension and medial/lateral (abduction/adduction). An example is the metacarpophalangeal joints of the hand between the distal metacarpal and proximal phalanx, commonly known as the knuckle.
