Question

The characteristics and an example of a synovial joint in humans are:

A

Fluid-filled between two joints, provides cushion; Skull bones

B

Lymph filled between two bones, limited motion; Gliding joint between carpals

C

Fluid-filled synovial cavity between two bones; Joint between atlas and axis

D

Fluid cartilage between two bones, limited motion; Knee joint

Step-by-Step Solution

synovial joints are uniquely characterised by the presence of a fluid-filled synovial cavity situated between the articulating surfaces of two bones . This specific anatomical arrangement allows for considerable movement, playing a vital role in locomotion . The pivot joint between the atlas and axis is explicitly cited as an example of a synovial joint . Other options are incorrect because skull bones are connected by fibrous joints that permit no movement , and the fluid within these joints is synovial fluid, not lymph .

Exam Context & Concepts Covered

This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Locomotion and Movement. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
