Examples of Using OTIC in a Sentence

• Researchers have identified eyes, cranial cartilages, at least six to nine gill arches, possible nasal sacs and otic capsules from its head.
• The ear develops from the first pharyngeal pouch and six small swellings that develop in the early embryo called otic placodes, which are derived from the ectoderm.
• The otic ganglion is a small (2–3 mm), oval shaped, flattened parasympathetic ganglion of a reddish-grey color, located immediately below the foramen ovale in the infratemporal fossa and on the medial surface of the mandibular nerve.
• It is one of four parasympathetic ganglia of the head and neck, (the others being the submandibular, otic, and ciliary ganglion).
• The nerve also conveys post-ganglionic parasympathetic fibres from the otic ganglion to the parotid gland.
• Among its primitive features, Diadectes has a large otic notch (a feature found in all labyrinthodonts, but not in reptiles) with an ossified tympanum.
• Lesser petrosal nerve (also known as the lesser superficial petrosal nerve) from the geniculate ganglion to the otic ganglion.
• As with the entirety of the inner ear organs and associated sensory organs, the vestibular ganglion is established from a sole embryonic source, the otic placode and is formed during neurogenesis.
• Ericiolacerta parva was described as a small, fossilized reptile preserved extremely well, despite the skull being partially crushed before it was buried, resulting in distortion of the occipital, otic, and mandibular bones, as well as the loss of part of the premaxillae and zygoma.
• The infratemporal fossa contains the mandibular nerve, the inferior alveolar nerve, the lingual nerve, the buccal nerve, the chorda tympani nerve, and the otic ganglion.
• It also contains parasympathetic axons which continue as the lesser petrosal nerve to the otic ganglion, which itself gives off postganglionic parasympathetic neurons.
• The lesser petrosal nerve (also known as the small superficial petrosal nerve) is the general visceral efferent (GVE) nerve conveying pre-ganglionic parasympathetic secretomotor fibers for the parotid gland from the tympanic plexus to the otic ganglion (where they synapse).
• It issues 1-2 twigs which traverse the otic ganglion (without synapsing) to reach and innervate the tensor tympani muscle, and tensor veli palatini muscle.
• Other diagnostic features of the skull include: long and narrow nasals, whose length is equivalent to approximately one third of the midline length of the skull; posteriorly closed otic notch; parietal is large and extends anteriorly beyond margin of orbit; parietals are longer than the frontals; postfrontal length is greater than twice its width and equal to the length of the supratemporal; cheek is steeply inclined and meets the skull table at nearly right angle.
• It possessed large otic (spiracular) notches, probably accommodating a spiracle rather than a tympanic membrane.
• A fracture classification system in which temporal bone fractures detected by computed tomography are delineated based on disruption of the otic capsule has been found to be predictive for complications of temporal bone trauma such as facial nerve injury, sensorineural deafness and cerebrospinal fluid otorrhea.
• The central part of the otic vesicle represents the membranous vestibule, and is subdivided by a constriction into a smaller ventral part, the saccule, and a larger dorsal and posterior part, the utricle.
• Like the parotid and buccal glands, the labial glands are innervated by parasympathetic fibres that arise in the inferior salivatory nucleus, travel with the glossopharyngeal nerve and lesser petrosal nerve to the otic ganglion, where they synapse and then continue to the labial glands.
• The uncrushed braincase of Dwykaselachus indicates that symmoriiforms are members of Holocephali, as much of the internal anatomy, including the otic labyrinth and brain space configuration are similar to those of chimaeras.
• Stethacanthids are medium-sized cladodont shark-like holocephalians with a short rostrum, broad supraorbital region, and short otic region.
