Relating to or situated on the outside; external or outer in anatomical position.
From Greek ektos 'outside' + -al suffix meaning 'relating to.' A direct adjectival form used in medical and biological terminology to describe external or outer structures.
Ectal is to anatomy what 'outer' is to everyday language, but it's specifically used when you need to sound scientific—doctors prefer ectal layers when describing skin structure, meaning the outermost parts of tissues.
