Answer :
Final answer:
None of the conditions listed are classified as arthritis by the VA. Arthritis involves inflammation and cartilage breakdown, while the conditions mentioned are more related to spinal disc and vertebrae issues.
Explanation:
Regarding the conditions considered arthritis by the VA, none of the options listed - herniated disc, degenerative disc disease, or spondylolisthesis - are classified strictly as arthritis. Arthritis is characterized by inflammation, pain, and swelling of the joints due to the breakdown of cartilage. In particular, osteoarthritis is associated with "wear and tear" of cartilage. Conditions such as herniated discs and degenerative disc diseases involve spinal issues related to the intervertebral discs and vertebrae but are not classified as arthritis by the VA.
The joint between adjacent vertebrae that includes an intervertebral disc is classified as an amphiarthrosis joint, which allows for a slight amount of movement and is more stable than freely movable joints.
