mandibular canal การใช้

• A fatty pad on the mandibular canal suggests that eomysticetids could hear underwater.
• The mandibular canal, with the mental foramen opening from it, is closer to the alveolar border.
• When placed in the mandibular canal with the inferior alveolar nerve exposed there have been reports of neurotoxic effects.
• With age and tooth loss, the alveolar process is absorbed so that the mandibular canal becomes nearer the superior border.
• Furthermore, the most important factor for inferior alveolar nerve-injury prediction is the proximity of the root tips to the mandibular canal.
• In human anatomy, the "'mandibular canal "'is a canal within the alveoli and communicates with them by small openings.
• The mental foramen opens midway between the upper and lower borders of the bone, and the mandibular canal runs nearly parallel with the mylohyoid line.
• Although superficially similar to thalassotherian chaeomysticetes, their large mandibular canal indicates that they were incapable of lunge-feeding as in modern-day balaenopterids.
• Sometimes with excessive alveolar process absorption, the mandibular canal disappears entirely and leaves the inferior alveolar nerve without its bony protection, although it is still covered by soft tissue.
• It runs along the mandibular canal in the substance of the bone, accompanied by the nerve, and opposite the first premolar tooth divides into two branches, incisor and mental.
• The mandibular canal, after the second dentition, is situated just above the level of the mylohyoid line; and the mental foramen occupies the position usual to it in the adult.
• The mandibular canal runs obliquely downward and forward in the ramus, and then horizontally forward in the body, where it is placed under the alveoli and communicates with them by small openings.
• Page 237 includes : " In " Steropodon ", the mandibular canal suggests the presence of a bill, with a bill also known in " Ornithorhynchus anatinus " ."
• The mandibular incisive canal ( indicated here by coral green arrows ) continuing anteriorly ( to the right ) from the mandibular canal ( purple arrows ) after the mental foramen ( light green circle)
• Rarely, a bifid inferior alveolar nerve may be present, in which case a second mandibular foramen, more inferiorly placed, exists and can be detected by noting a doubled mandibular canal on a radiograph.
• While in the mandibular canal within the mandible, it supplies the mandibular ( lower ) teeth ( molars and second premolar ) with sensory branches that form into the inferior dental plexus and give off small gingival and dental nerves to the teeth.
• The mandibular canal is of large size and runs near the lower border of the bone; the mental foramen opens beneath the socket of the first deciduous coronoid process is of comparatively large size, and projects above the level of the condyle.
• One branch of it, the inferior alveolar nerve as well as the inferior alveolar artery enter the foramen traveling through the body in the mandibular canal and exit at the mental foramen on the anterior mandible at which point the nerve is known as the mental nerve.
• "Dalanistes " is similar to but 20 % larger than " Remingtonocetus "; the external nares are located more anteriorly ( above C 1 ); the sagittal crest is much higher; the rostrum is angled down 20?relative to the main axis of the braincase; the mandibular symphysis is relatively open ( ends at P 3 ) and the mandibular canals fail to unite at the symphysis.
