Joints found at the vertebrae are:
- A
Gliding joints
- B
Sliding joints
- C
Partially moveable joints
- D
Fixed joints
- E
Pivot joints
Gliding joints are present between vertebrates.
Gliding joints, also known as planar joints, allow for limited movement between the surfaces of the vertebrae, particularly at the facet joints (zygapophyseal joints).
Sliding joints is not a recognized term in anatomical classifications. This option may confuse students as it is often used colloquially to describe gliding joints, which do not specifically refer to the vertebral column.
Partially movable joints, also called cartilaginous joints. These joints allow limited movement while providing stability, making them essential for the flexibility of the spine. Hence, this option is incorrect.
Fixed joints, or synarthroses, do not allow any movement and are exemplified by the joints in the skull. They are not found in the vertebral column, which requires flexibility and movement.
Pivot joints are designed for rotational movement, such as in the neck and forearm. They do not play a significant role in the movement between vertebrae, which primarily involve partially movable joints.
