- A. Main source of oxygenated blood to palatine tonsil
- B. Is a branch of internal carotid artery
- C. Supplies branches to both upper and lower lips
- D. Conveys post ganglionic sympathetic nerve fibres to the submandibular gland
Explanation: The facial artery is a branch of the external carotid artery, not the internal carotid artery.
Correct answer: Is a branch of internal carotid artery- A. Inferior petrosal sinus
- B. Pterygoid venous plexus
- C. Veins in orbit
- D. Sigmoid and straight sinus
Explanation: The cavernous sinus communicates with the inferior petrosal sinus, orbital veins and the pterygoid plexus through emissary veins.
Correct answer: Sigmoid and straight sinus- A. Middle cerebral artery
- B. External carotid artery
- C. Internal carotid artery
- D. Ophthamic artery
Explanation: The posterior communicating artery arises from the internal carotid artery and runs posteriorly to join the posterior cerebral artery.
Correct answer: Internal carotid artery- A. Above the line joining tragus to the nasal fold
- B. Area drained by angular facial vein
- C. Spheno - ethmoidal recess
- D. All of the above
Explanation: The dangerous area of the face is clinically important because the facial vein communicates through the angular and ophthalmic veins with…
Correct answer: Area drained by angular facial vein- A. Intra cavernous
- B. Intra petrous
- C. Intra cerebral
- D. Extra cranial
Explanation: The ophthalmic artery arises from the intracranial, or cerebral/supraclinoid, part of the internal carotid artery after it emerges from…
Correct answer: Intra cerebral- A. Ascending pharyngeal
- B. Middle meningeal
- C. Artery of pterygoid canal
- D. All of the above
Explanation: The auditory tube receives arterial branches from the ascending pharyngeal artery, middle meningeal artery and artery of the pterygoid…
Correct answer: All of the above- A. Stage - I
- B. Stage - II
- C. Stage - III
- D. Stage - IV
Explanation: The first stage of swallowing transfers the bolus from the mouth into the oropharynx and is under voluntary control.
Correct answer: Stage - I- A. Cavernous sinus
- B. Superior petrosal
- C. Transverse sinus
- D. All of the above
Explanation: The cavernous, superior petrosal and transverse sinuses are all paired dural venous sinuses, with right and left members.
Correct answer: All of the above- A. Vagus nerve
- B. Internal carotid artery
- C. Common carotid artery
- D. External carotid artery
- E. Internal jugular vein
Explanation: The carotid sheath encloses the common or internal carotid artery, internal jugular vein and vagus nerve.
Correct answer: External carotid artery- A. Superficial temporal
- B. Maxillary
- C. Facial
- D. Internal carotid artery
Explanation: The transverse facial artery arises from the superficial temporal artery within the parotid gland and runs forward across the face.
Correct answer: Superficial temporal- A. Superficial temporal and maxillary veins
- B. Superficial temporal and internal jugular vein
- C. Superficial temporal and supratrochlear
- D. Maxillary and posterior auricular
Explanation: The retromandibular vein forms within the parotid gland by the union of the superficial temporal and maxillary veins.
Correct answer: Superficial temporal and maxillary veins- A. aboe hyoid bone
- B. Hyoid bone
- C. Above Styloid process
- D. Below hyoid bone
Explanation: The facial artery arises from the external carotid artery just above the greater horn of the hyoid bone.
Correct answer: aboe hyoid bone- A. Transverse facial vein
- B. Superior ophthalmic vein
- C. Maxillary vein
- D. Ethmoidal vein
Explanation: The facial vein communicates with the cavernous sinus through the angular vein and the superior ophthalmic vein.
Correct answer: Superior ophthalmic vein- A. Sub mandibular nodes
- B. Deep cervical nodes
- C. Retro pharyngeal nodes
- D. Sub mental nodes
Explanation: Dental lymph usually reaches the submandibular, submental and deep cervical nodes, depending on the tooth involved.
Correct answer: Retro pharyngeal nodes- A. Lingual artery
- B. Superior thyroid artery
- C. Facial artery
- D. Pharyngeal artery
Explanation: The tonsil receives its main arterial supply from the tonsillar branch of the facial artery, with contributions from several neighbouring…
Correct answer: Facial artery- A. ovale
- B. Rotundum
- C. Stylomastoid
- D. Spinosum
Explanation: The middle meningeal artery enters the cranial cavity through the foramen spinosum.
Correct answer: Spinosum- A. Superficial temporal and transverse facial
- B. Transverse facial and maxillary
- C. Posterior auricular and maxillary
- D. Superficial temporal and maxillary
Explanation: The external carotid artery ends by dividing into the superficial temporal and maxillary arteries within the parotid gland.

- B. Inferior ophthalmic vein
- C. Connecting pterygoid plexus
- D. None of the above
Explanation: The angular continuation of the facial vein communicates with the cavernous sinus through the superior ophthalmic vein.

- B. Internal carotid artery
- C. Trigeminal artery
- D. Facial artery
Explanation: The maxillary artery is one of the two terminal branches of the external carotid artery, the other being the superficial temporal artery.
