Descriptions for Clinical findings and disorders Disorders should follow the naming guidelines for Body structures if they are to be used within the Clinical finding/disorder concept.

Concepts describing limbs are abundant, and the use of limb in the FSN and the synonyms of upper/lower extremity, arm/leg should be followed.

For example, 

• • 249945007 |Monoparesis of lower limb (disorder)|

Because the finding site is 61685007 |Lower limb structure (body structure)|, which follows the anatomical guidelines, the disorder concept reflects lower limb in the FSN, while using synonyms of Monoparesis of leg and Monoparesis of lower extremity.  

Disorder

 In the disorder hierarchy, the following naming conventions apply:

...

The term cerebral is used in clinical language to mean both cerebrum, and more broadly, brain.   

• If the condition is limited to the cerebrum, the FSN, PT, and finding site will reflect the cerebrum.  A synonym will remain with the term cerebral. 
• If the condition refers more broadly to the brain, the FSN, PT, and finding site will reflect the brain – unless the proper name of the condition uses the term cerebral, as in Cerebral palsy.    A synonym will remain with the term cerebral if it is commonly used to refer to the condition.

The term Disorder

 The word disorder should be singular, so Disorder of nose, not Disorders of nose.

• When the concept is a general grouping of disorders of a body system, body site, or other broad category, the word disorder is preferred over the word disease for the FSN, e.g. Disorder of reproductive system, not Disease of reproductive system. This does not apply at the leaf level.
