Preferred Label : cervical loop;
Uberon definition : The cervical loop is the location on an enamel organ in a developing tooth where the
outer enamel epithelium and the inner enamel epithelium join. The cervical loop is
a histologic term indicating a specific epithelial structure at the apical side of
the tooth germ, consisting of loosely aggregated stellate reticulum in the center
surrounded by stratum intermedium. These tissues are enveloped by a basal layer of
epithelium known on the outside of the tooth as outer enamel epithelium and on the
inside as inner enamel epithelium. During root formation the inner layers of epithelium
disappear and only the basal layers are left creating Hertwig's Epithelial Root Sheath
(HERS). At this point it is usually referred to as HERS instead of the cervical loop
to indicate the structural difference[WP].;
