Most of the joints in the appendicular skeleton are __________ joints.
Semmy [17]

Most of the joints in the appendicular skeleton are synovial joints.

So, the correct option is (c).

  • A joint, sometimes referred to as an articulation, is where two or more bones come together. The names of two bones are included in each articulation.
  •  Immobile joints are ones that do not permit movement at the joint sites .These joints don't have a joint cavity; instead, dense fibrous connective tissue, typically collagen, holds the bones physically together.
  • A synovial membrane-lined joint capsule that produces synovial fluid surrounds and protects the two of them.
  • Specialized joints known as cartilaginous joints can be identified by their structural characteristics.
  • In fibrous joints, white connective tissue  fibres that travel from one articulating portion to the next separate the articulating parts.
