| auditory pits | Paired depressions, one on either side of the head of the embryo, marking the location of the future auditory vesicles. Synonym: otic pits. (05 Mar 2000) |

| granular pits | Pits on the inner surface of the skull, along the course of the superior sagittal sinus, in which are lodged the arachnoidal granulations. Synonym: foveolae granulares, pacchionian depressions. (05 Mar 2000) |
| coated pits, cell-membrane | Specialised regions of the cell membrane composed of pits coated with a bristle covering made of the protein clathrin. These pits are the entry route for macromolecules bound by cell surface receptors. The pits are then internalised into the cytoplasm to form the coated vesicles. (12 Dec 1998) |
| commisural pits | Similar to lip pits but found at the labial commisures. (05 Mar 2000) |
| nail pits | Small punctate depressions on the surface of the nail plate due to defective nail formation; seen in psoriasis and other disorders. See: geographic stippling of nails. (05 Mar 2000) |
| nasal pits | The paired depressions formed when the nasal placodes come to lie below the general external contour of the developing face as a result of the rapid growth of the adjacent nasal elevations; the pit's are the primordia of the rostral portions of the nasal chambers. Synonym: olfactory pits. (05 Mar 2000) |
| iris pits | Colobomas affecting the stroma of the iris with pigment epithelium intact. (05 Mar 2000) |
| olfactory pits | The paired depressions formed when the nasal placodes come to lie below the general external contour of the developing face as a result of the rapid growth of the adjacent nasal elevations; the pit's are the primordia of the rostral portions of the nasal chambers. Synonym: olfactory pits. (05 Mar 2000) |
| lens pits | The paired depressions formed in the superficial ectoderm of the embryonic head as the lens placodes sink in toward the optic cup; the external openings of the pit's are closed as the lens vesicles are formed. (05 Mar 2000) |
| lip pits | Malformations of the lip seen in unilateral or bilateral depressions or fistulae. May be hereditary or associated with cleft lip and/or palate. (05 Mar 2000) |
| barotrauma, otic | See: Barotitis. (12 Dec 1998) |
| communicating branch of otic ganglion to auriculotemporal nerve | <anatomy, nerve> A branch of the otic ganglion joining the roots of the auriculotemporal nerve to convey postsynaptic parasympathetic fibres to the parotid gland. Synonym: ramus communicans ganglii otici cum nervo auriculotemporali. (05 Mar 2000) |
| communicating branch of otic ganglion to chorda tympani | A small branch of the otic ganglion conveying sensory fibres to the chorda tympani. Synonym: ramus communicans cum chorda tympani. (05 Mar 2000) |
| communicating branch of otic ganglion with medial pterygoid nerve | <anatomy, nerve> Branch of otic ganglion joining the nerve to the medial pterygoid muscle. Synonym: ramus communicans ganglii otici cum nervo pterygoideo mediali. (05 Mar 2000) |
| communicating branch of otic ganglion with meningeal branch of mandibular nerve | <anatomy, nerve> A branch of otic ganglion to the meningeal branch of mandibular nerve conveying postsynaptic parasympathetic fibres which run back to the main stem of the mandibular nerve for distribution to the parotid gland via the auriculotemporal nerve. Synonym: ramus communicans ganglii otici cum ramo meningeo nervi mandibularis. (05 Mar 2000) |
