Back to paper

In humans, the neck is joined to the head by which of the following joints?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. Pivotal joint.

In humans, the neck is joined to the head by a pivotal joint (also known as a pivot joint). This joint allows the head to rotate from side to side, as seen in the atlas and axis vertebrae of the cervical spine.

Other options:

  • Ball and socket joint: Found in the shoulder and hip, allows movement in all directions.

  • Hinge joint: Found in elbows and knees, allows movement in one direction.

  • Fixed joint: Found in skull sutures, where no movement occurs.
