Question

Which of the following joints will allow no movement?
a) Ball and socket Joint
b) Fibrous Joint
c) Cartilaginous Joint
d) Synovial Joint

Answer 1

Joint meaning 'Arthrosis' or 'Articulation'. In simple words, Joint is the connection between two bones. These are responsible for Movement and Locomotion.

Complete answer:
A joint is a point of contact between two bones. These joints not only permit movement and locomotion but also provide mechanical support to the skeletal system.
The joints can be classified Structurally or Functionally. Structural classification explains how the bones are connected with each other and Functional classification explains the degree of the movement. The structures of the articulating bones will affect the degree of movement also.
Thus Structurally and Functionally the bones) are classified as

1. Fibrous Joints or Immovable Joints are Synarthroses (Syn-Fused)
2. Cartilaginous joints or Slightly movable Joints or Amphiarthroses (Amphi- Both)
3. Synovial joints or Completely movable Joints are Diarthroses (Dia-Movable).

Fibrous joints show presence of fibrous connective tissue in between the bones. This tissue is mainly collagen. Thus the movement is restricted. Thus it is an Immovable joint or Synarthroses (Syn- Fused and Arthrosis- Fused). Examples are Sutures in the skull, Gomphoses (Joint between teeth and the alveolar bone).

Thus the Answer is B.

Additional information:
Cartilaginous joint examples are Intervertebral disc, Pubic symphysis. Synovial joints are ball and socket, Hinge joints, Pivot joints, Saddle joints, Condyloid joint, etc.

Note: Sutures are seen in the cranium. These are not seen in newborn babies. Spaces are present instead of the sutures. The spaces are fontanelles. These help during the parturition process. Later on the sutures are formed.
