SAS11 Flashcards
What artery is a branch of the external carotid artery that supplies the jaw bones and teeth?
Internal maxillary artery
The internal maxillary artery is crucial for providing blood supply to the dental structures.
Which artery supplies the lower jaw?
Inferior alveolar artery
The inferior alveolar artery branches into the mental and incisive arteries.
What are the branches of the inferior alveolar artery?
- Mental artery
- Incisive artery
The mental artery supplies tissues of the chin and lower lip, while the incisive artery supplies the mandibular anterior teeth.
What artery supplies the upper jaw?
Superior alveolar artery
The superior alveolar artery has branches that supply different sections of the upper jaw.
List the branches of the superior alveolar artery.
- Posterior superior alveolar artery (PSA)
- Middle superior alveolar artery (MSA)
- Anterior superior alveolar artery (ASA)
These branches supply the maxillary molars, premolars, and anterior teeth respectively.
What does the descending palatine artery supply?
Bone, glands, and mucosa of the posterior 2/3 of the hard palate
It also supplies the bone and mucosa of the alveolar process.
What are the branches of the sphenopalatine artery?
- Short nasopalatine artery
- Long nasopalatine artery
The short nasopalatine artery supplies the nasal cavity, while the long nasopalatine artery supplies the anterior 1/3 of the hard palate.
What is the sensory nerve supply to the jaws and teeth derived from?
Maxillary and mandibular branches of the 5th cranial or trigeminal nerve
The trigeminal nerve is essential for dental sensation.
Fill in the blank: The mnemonic for the exit of the branches of the trigeminal nerve is _______.
Standing Room Only
This helps remember the pathways of the trigeminal nerve branches.
What are the exit points of the branches of the trigeminal nerve?
- Ophthalmic branch - Superior orbital fissure
- Maxillary branch - Foramen rotundum
- Mandibular branch - Foramen ovale
These exit points are crucial for understanding the anatomy of the trigeminal nerve.
Which branch of the maxillary nerve supplies the hard palate and palatal gingiva as far as the canine?
Anterior palatine branch
This branch is significant for the sensory supply of the anterior hard palate.
What does the inferior alveolar nerve (IAN) supply?
Inferior dental branch entering the individual tooth roots and interdental branches supplying the alveolar bone, periodontal membrane, and gingiva
The IAN is vital for the innervation of the lower teeth.
What does the mental nerve supply?
Lower lip and chin
The mental nerve is important for sensory innervation in the facial region.
True or False: The lingual nerve supplies the mucosa and gingiva of the tongue.
True
The lingual nerve is responsible for sensory innervation in the lingual region.
What nerve innervates the central incisor teeth and periodontal membrane?
Mylohyoid nerve
The mylohyoid nerve is involved in the sensory supply of specific teeth.
