Which branch of external carotid artery enters Pterygopalatine fossa?

maxillary artery
The maxillary artery, the larger of the two terminal branches of the external carotid artery, arises behind the neck of the mandible, and is at first imbedded in the substance of the parotid gland; it passes forward between the ramus of the mandible and the sphenomandibular ligament, and then runs, either superficial …

Which branch starts from Maxillaris in its first part?

mandibular division
The mandibular division (1st part) – named as such because it winds around deep to the neck of the mandible.

Which branch starts with Maxillaris in its 3 part?

It supplies the deep structures of the face. The maxillary artery is divided into three portions by its relation to the lateral pterygoid muscle: first (mandibular) part: posterior to lateral pterygoid muscle (five branches) second (pterygoid or muscular) part: within lateral pterygoid muscle (five branches)

What are the 3 different parts of the maxillary artery?

Pterygopalatine (3 part) of the maxillary artery[4]:

  • Pharyngeal artery: enters the palatovaginal canal.
  • Greater palatine artery: enters the greater palatine foramen.
  • Artery of the pterygoid canal.
  • Sphenopalatine artery: enters the sphenopalatine foramen.
  • Posterior superior alveolar artery.

What are the 3 branches of the external carotid artery?

The facial, maxillary and superficial temporal arteries form the major branches of note.

Which nerve Innervates the maxillary first and second premolars?

Posterior superior alveolar nerve
The posterior superior alveolar nerve innervates the second and third maxillary molars, and two of the three roots of the maxillary first molar (all but the mesiobuccal root)….

Anatomical terms of neuroanatomy

What bone makes up the medial wall of the pterygopalatine fossa?

the palatine bone
The walls of the pterygopalatine fossa are as follows: medial: perpendicular plate of the palatine bone.

What is pterygopalatine fossa?

The pterygopalatine fossa (PPF) is a cone-shaped depression deep to the infratemporal fossa and posterior to the maxilla on both sides of the skull. The fossa is located between the pterygoid process and the maxillary tuberosity, close to the orbital apex.

What are the 4 branches of the external carotid artery?


  • superior thyroid artery.
  • ascending pharyngeal artery.
  • lingual artery.
  • facial artery.
  • occipital artery.
  • posterior auricular artery.

What are the 8 branches of the external carotid artery?

The major ECA branches are the superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior auricular, superficial temporal, and maxillary arteries.

What nerve Innervates maxillary teeth?

The superior alveolar nerves, anterior, and posterior, form a loop within the maxilla. From this loop dental and gingival branches arise that supply the upper teeth, and the upper gums. The maxillary nerve also gives off palatine and nasopalatine branches that supply the palate, and parts of the nasal cavity.

Which nerve Innervates the maxillary centrals laterals and canines?

Answer. The anterior superior alveolar (ASA) nerve block anesthetizes the maxillary canine, the central and lateral incisors, and the mucosa above these teeth, with occasional crossover to the contralateral maxillary incisors (see image below).
