LESSON #3 (6 HOURS)
Theme: Temporal bone. Maxilla. Palatine bone. Nasal, lacrimal, zygomatic, bones. Inferior nasal concha, vomer, mandible. Hyoid bone.
Aim. To study structure of the temporal bone and its parts, to elucidate way of the canals.
To study structure, location and correlation viscerocranium elements with adjacent bones of face.
Professional orientation of students: knowledge the structure of temporal bone and its parts allows to understand morphological peculiarities of cavities for external, middle and internal ear, passage the cranial nerves also important vessels. The correct structure and position of temporal bone are very important for normal functioning of hearing and balansing sensority, innervating different organs. knowledge the structure of facial portion of the skull allows to understand morphological peculiarities of cavities for eyes, nose, mouth, pharynx and cranial nerves also important vessels, action of the mastication and neck muscles. The correct structure and position of viscerocranium elements are very important for normal functioning of oral digestive and respiratory organs. Understanding the structure is a fundamental base for the neurosurgical, and therapeutical practice also traumatology and ENT specialist.
Structure of thoracic vertebrae, roman (Latin) terminology.
I. Practical work – 9:00-12:00 am (4 hours)
1) Illustrative materialss:
Training X-ray film, CT scans and MRI.
2) Methodology of Practical Class.
Work 1.. Studying anatomy of temporal bone
After the consultation, using textbooks and atlases, to learn an anatomy of temporal bones on separate preparations, sections and on skull.
Work 2: . Studying anatomy of facial skull
After the active teacher’s consultation, using textbooks and atlases, to learn an anatomy of facial skull bones on separate preparations and on skull.
3) Demonstrate on preparations:
Skull: topografy of the temporal fossa.
Temporal bone: petrous, tympanic and sguamous parts. Petrosguamous, petrotympanic, tympanomastoid, tympanosguamous fissure. Petrous part: surfaces, grooves, foramens, fossas, processes. Tympanic part: external acoustic opening. Sguamous part: margins, surfaces, grooves, processes. Canals: carotid, musculotubal, facial; canaliculus: for chorda tympani, tympanic, mastoid.
Temporal bone: facial canal, walls of the tympanic cavity, osseous labyrinth.
Maxilla: body, orbital, infratemporal, nasal and anterior surfaces. Frontal process, alveolar process, palatine and zygomatic process.
Palatine bone: horizontal and perpendicular plate; ethmoid and conchal crests; orbital, sphenoidal and pyramidal processes; palatine canal.
Mandible: body, base, mental protuberance, mental spine; digastric, sublingual and submandibular fossaes; mylohyoid line, alveolar arch, dental alveoli, interalveolar septa, alveolar yokes. Ramus of the mandible: angle, masseteric and pterygoid tuberosity, coronoid process, mandibular notch, mandibular foramen, condylar process, head and neck of the mandible.
Zygomatic bone: lateral, temporal and orbital surfaces; temporal and frontal process; zygomaticofacial, zygomaticoorbital and zygomaticotemporal foramens.
Nasal bone: ethmoid groove.
Lacrimal bone: posterior lacrimal crest, lacrimal groove.
Inferior nasal concha: lacrimal, maxillar and ethmoidal processes.
Vomer: wing of the vomer.
Hyoid bone: body, greater and lesser horns.
