- Operculum (in pregnancy), the cervical mucus plug that blocks the cervix of the uterus after conception
- Operculum (brain), the part of the brain covering the insula
- Operculum (dentistry), a small flap of tissue which may cover an erupting or partially erupted molar
In animal biology:
- Operculum (animal), a structure resembling a lid or a small door that opens and closes
- Operculum (fish), a flap of the bony fish covering the gills
- Operculum (gastropod), a sort of trapdoor used to close the aperture of some snails
- Operculum (bird), a structure which covers the nares of some birds
- Operculum (bryozoa), a lid on the orifice of some bryozoans
- Operculum, the anterior end of the fruit fly puparium, through which the adult fly emerges
In botany:
- Operculum (botany), various lids and flaps pertaining to plants, algae and fungi

- Rule and similarity in grammar: Their interplay and individual differences in the brain.
- Hauser MF, Hofmann J, Opitz B.AbstractPrevious research on artificial grammar has indicated that the human ability to classify sentences or letter strings according to grammaticality relies on two types of knowledge. One is a superficial, familiarity-based understanding of a grammar the other is the knowledge of rules and critical features underlying a grammar. The fundamentally different characteristics of these systems permit an analysis of receiver-operating characteristics (ROC), which measures the extent to which each type of knowledge is used in grammaticality judgments. Furthermore, violations of a grammar can be divided into hierarchical and local violations. The present study is the first to combine the use of ROC analyses, fMRI and a grammaticality dichotomy. Based on previous neuroimaging studies, it was hypothesized that judgments based on rule knowledge, as extracted from individual ROC analyses, involve the left inferior frontal gyrus (IFG), whereas similarity would involve right IFG, as well as left hippocampal regions. With regards to violation types, it was hypothesized that hierarchical violations would recruit the opercular part of the left IFG as well as the posterior operculum, whereas local violations would bilaterally activate the premotor cortex (PMC). Results indicated that for greater reliance on rule knowledge, a ventral part of the left PMC was activated for ungrammatical items, whereas other PMC areas show a differentiated response for grammaticality for individuals less reliant on similarity. The right IFG was related to ungrammatical items as a function of similarity. Results are discussed with regards to possible error detection systems and differentiated efficiencies for respective classification strategies.

- … Differences in females were seen in the posterior processes of the genital operculum, shape of the genital flap, and medial spinules on the first exopodal segment of the fifth leg, and those in males were in the shape of the first exopodal segment of the fifth left leg, and position of the medial process on the third exopodal segment of the fifth right leg. … Among these morphologies, the length of the genital operculum process discretely separated each group, but variations in the other morphometric characters were overlapping. …
