Question

Which one among the following is a cartilaginous joint?
A)Synchondrosis
B)Symphysis
C)Diarthrosis
D)Both A and B

Answer 1

Hint: It is a bone that is joined by hyaline cartilage. It is temporary and permanent and mostly found in the thoracic cage and other bones are joined by fibrocartilage and important in carrying heavy objects.

Complete answer:
Cartilaginous joint - these are the joints collected by cartilage i.e fibrocartilage or hyaline. These joints help in the movement of bones. In cartilaginous bones where the connective medium is hyaline is called as Synchondrosis or primary cartilaginous joint. These are the first sternocostal joints (the first rib meets the sternum).
-In cartilaginous bones where the connective medium is fibrocartilage is called Symphysis. It is a secondary cartilaginous joint, which is permanent and slightly movable. Pubic Symphysis is a more prominent Symphysis. It is the middle cartilaginous bones which unite the superior rami of the right and left pubic bones. It may also contain a fluid-filled cavity.

Additional Information: Pubic Symphysis is present above the vulva in females and above the penis in males and located anterior to the urinary bladder and superior to the external genitalia. When the legs are stretched, pubic Symphysis widens.
Diarthrosis - These are the synovial joints that include most of the joints in our body. These joints have a wide range of motion. These are freely movable joints with a joint cavity. A joint cavity consists of a joint capsule and a synovial membrane present inside the joint and produces a fluid known as synovial fluid. The joint having synovial fluid is called synovial joints. Synovial joints are of different types on the basis of their movement.

So, the correct answer is, "both A and B".

Note: The vertebral disc is present between adjacent vertebrae in the spine. To allow a slight movement of the vertebrae, each disc forms a cartilaginous joint and acts as a ligament to hold the vertebrae together.
Synovial joints are of four types- Nonaxial joints, Uniaxial or Mono-axial joints, Biaxial joints, and Triaxial joints.
