What does MM refer to in a veterinary examination?

In a veterinary examination, "MM" stands for moist mucous membranes. This term is used to describe the condition of the mucous membranes in a patient's mouth or other areas. Assessing the moisture of these membranes is an important part of a physical examination, as it can provide valuable information about the animal's hydration status and overall health.

Moist mucous membranes indicate proper hydration and good circulation, while dry or tacky membranes could suggest dehydration or other health issues. By evaluating the appearance and moisture level of the mucous membranes, veterinarians can gain insights into the animal's systemic health and potential underlying conditions that may require further investigation or intervention.

The other options listed do not accurately reflect a commonly recognized term in veterinary practice. Therefore, moist mucous membranes is the most relevant choice in this context.
