The isthmus of the thyroid gland lies over the 2nd, 3rd and 4th Tracheal ring

Superior Parathyroid gland?

Correct! Wrong!

Schindylesis suture is present between which bones?

Correct! Wrong!

Schindylesis is an articulation in which two bones are joined by fitting the ridge of one bone into the groove of another. Also known as a "wedge-and-groove" joint, the name is derived from the Greek 'skhindulesis', meaning "to cleave", as in cutting with a stump with an axe. This fibrous suture joint can be found between the vomer and the perpendicular plate of the ethmoid bone as well as between the vomer and the gap between the maxilla and palatine.

Parathyroid Hyperplasia involves?

Correct! Wrong!

The proliferation involves chief cells, clear cells, and oxyphil cells, which are arranged in sheets, trabeculae, or acini.

Inion is?

Correct! Wrong!

The inion is the tip of the external occipital protuberance (EOP), the midline bony prominence in the occipital bone from which the ligamentum nuchae and trapezius muscle attach. It is usually easily palpable. It is the surface marking of the internal attachment of the tentorium cerebelli. It is one of the skull landmarks, craniometric points for radiological or anthropological skull measurement.

Which of the following is not a pneumatic bone?

Correct! Wrong!

Pneumatic bones are those which enclose an air filled cavity. They are seen in relation to the nasal cavity (paranasal sinuses) and the middle ear. The pneumatic bones are: 1: Frontal 2: Sphenoid 3: Ethmoid 4: Maxilla 5: Temporal (mastoid air cells)

Medial Canthal Ligament attachment?

Correct! Wrong!

The medial palpebral ligament (medial canthal tendon) is about 4 mm in length and 2 mm in breadth. Its anterior attachment is to the frontal process of the maxilla in front of the lacrimal groove, and its posterior attachment is the lacrimal bone.

True regarding superior parathyroid gland?

Correct! Wrong!

The majority of parathyroid glands receive their blood supply from the inferior thyroid artery; however, the superior parathyroid gland may get its own blood supply through the superior thyroid vessels.

Which of the following is supplied by mandibular nerve?

Correct! Wrong!

The masseteric nerve crosses the posterior part of the mandibular notch with the masseteric vessels to enter the deep surface of the masseter, to which it supplies motor fibers. It also provides a sensory branch to the TMJ.

Which bone ossifies by both Secondary Ossification and Enchondral Ossification?

Correct! Wrong!

Mandible is formed by both intramembranous and endochondral ossification. • Part of the mandible between mental and mandibu-lar foramina ossifies in membrane from mesenchy-mal sheath of Meckel's cartilage (first arch cartilage). • Part of the mandible medial to mental foramen os-sifies directly from Meckel's cartilage (endochon-dral ossification). • Coronoid and condylar processes ossify from secondary cartilages not related to Meckel's cartilage.

Sensation of lower teeth carried by?

Correct! Wrong!

The inferior alveolar nerve (sometimes called the inferior dental nerve) is a branch of the mandibular nerve, which is itself the third branch of the trigeminal nerve. The inferior alveolar nerves supply sensation to the lower teeth.

True regarding superior parathyroid glands?

Correct! Wrong!

The majority of parathyroid glands receive their blood supply from the inferior thyroid artery; however, the superior parathyroid gland may get its own blood supply through the superior thyroid vessels.

Regarding parathroid what is correct?

Correct! Wrong!

The majority of parathyroid glands receive their blood supply from the inferior thyroid artery; however, the superior parathyroid gland may get its own blood supply through the superior thyroid vessels.

True about superior parathyroid gland?

Correct! Wrong!

In adult bone formation occurs at all except?

Correct! Wrong!

Sympathetic fibres are present in?

Correct! Wrong!

Patient is presented with Trigeminal Neuralgia? Anasthseia given to block Trigeminal nerve in?

Correct! Wrong!

Trigeminal nerve can be blocked utilizing an extra oral approach via the coronoid notch into the pterygopalatine fossa.
