The pivot joint is present in the neck.
The pivot joint, as the name suggests, allows for rotational movement around a single axis. This is crucial for the neck's ability to rotate the head from side to side. The specific pivot joint in the neck is the atlantoaxial joint, located between the first and second cervical vertebrae (C1 and C2, also known as the atlas and axis, respectively).
Here's a breakdown:
-
Pivot Joint Definition: A joint that allows rotary movement around a single axis.
-
Location in the Neck: Specifically, the atlantoaxial joint between the atlas (C1) and axis (C2) vertebrae.
-
Function: Enables the head to rotate from side to side, facilitating movements like shaking your head "no." The reference states, "This type of joint is found in the neck."
-
Example: Shaking your head "no" is a primary example of the pivot joint in action in the neck.
