About Cross Section

Where the answers come from

One dataset of two hundred keys: a question catalog plus structured tables – the combining
forms and suffixes of medical terminology, which organ belongs to which system, all twelve
cranial nerves, and the body’s countable numbers. Two independent authors filled in every key
without seeing each other’s work, and the two copies were compared value by value: all two
hundred agreed. Where authors cannot both vouch for an answer, the site asks no question.

What this site is not

It is not a medical resource. Every question here is textbook anatomy and nomenclature –
what a structure is called, where it sits, what system it belongs to. Nothing on this site
diagnoses, treats, or advises; nothing should be read as guidance about any person’s health.
Students use pages like these to drill for anatomy class, and that is the whole intent.
