1

Name the branches of the external carotids:

1. superior thyroid
2. ascending cervical
3.Lingual
4. Facial
5. Occipital
6.Posterior auricular
7.Maxillary
8.Superficial temporal

2

What is the origin of the middle meningeal artery?

maxillary artery (external carotid)

3

Which branch of the EC can be damaged around the mandible?

Facial artery

4

What nerve supplies the majority of the pharyngeal muscles?

Vagus muscle
EXCEPT: stylopharyngeal is innervated by the glossopharyngeus

5

What are the pharyngeal muscles composed by

The pharyngeal muscles consist of three constrictors (superior, middle and inferior) and three longitudinal muscles:
1. Stylophargeus
2.palatopharyngeus
3.Salpingophargeus (DON't need to know)

6

In addition to the tubal tonsils,* there are three more. What are they?:

1. the lingual
2. the palatine tonsil
3. the pharyngeal tonsil

7

What is the function of the palatopharyngeal and the palatoglossus

the both depress the soft pallet

8

What is the innervation of the pharynx?

- VAGUS AND GLOSSOPHARGEUS

EXPEPTION some of the nasopharynx is innervated by the maxillary nerve V2

9

Describe the sensory innervation to the anterior 2/3 of the tongue

TASTE: is the facial nerve (chorda tympany joins the lingual nerve)

SENSATION: Lingual nerve (Trigeminal V3)

10

Describe the sensory innervation to the posterior 1/3 of the tongue:

GLOSSOPHARYNGEAL

11

What nerve supplies the epiglottic vallecula?:

VAGUS

12

What nerves supply the motor component of the tongue?

Hypoglossal - cranial nerve 12

ALL BUT the Palatoglossus - Vagus

13

Name the four tongue muscles and describe their action:

KEEP IN MIND the tongue has extrinsic and intrisic muscles
1. Palatoglossus
2. Styloglossus
3. Hyoglossus
4. Genioglossus

14

Name the four tongue muscles and describe their action:

KEEP IN MIND the tongue has extrinsic and intrisic muscles
1. Palatoglossus- does not do much with the tingue seals off the cavity
2. Styloglossus - elevates and retracts
3. Hyoglossus - depresses tongue
4. Genioglossus - protrude the tongue (attaches to the mandible)

15

What are the two actions of the temporo-mandibular joint?

hinge and glide movements

16

What anatomical structures form the temporomandibular joint?

1. head of the mandible
into the mandibular fossa created by teh articular tubercle

17

Name the attachments and function of the temporalis muscle:

Attaches to the temporal fossa and the coronoid process of the mandible

FUNCTION: elevation and retraction

18

Name the attachments and function of the masseter muscle:

Attacments: Zygomatic arch and the lateral surface of the ramus of the mandible

FUNCTION: elevation

19

Name the functions of the medial pterygoids:

Attachments: lateral pteroid plate and sphenoid - neck of the mandible


Function: protraction and depression

20

Name the functions of the lateral pterygoids:

Attachement: lateral pterygoid plate and maxilla and angle of the mandible

Function: elevation and protraction and lateral movement

21

Name the branches of V3:

1. Long buccal (anterior division)
2. lingual (posterior)
3. inferior alveolar (posterior)

22

Describe the sensory innervation of the face by the 3 divisions of the trigeminal:

V1 (frontal nerve): forehead, upper eyelid
V2. skin of middle of the face (including teeth, gums and upper lips)
V3. (buccal nerve) middle part of the temple cheeks and the floor of the mouth

23

Name four muscles innervated by the anterior branch of V3:

Masseter
temporalis
pterygoids
suprahyoid (via mylohyoid nerve from the inferior alveolar nerve)

24

What are the 5 branches of the facial nerve which supply the muscles of facial expression?:

Temporal
Zygomatic
Buccal
Mandibular
Cervical

25

What is Bell’s palsy and how does it present?:

ipsylateral facial drooping

26

Name the 3 salivary glands, their innervation and type of secretion:

Sublingual - facial nerve
Submandibular -facial nerve
Parotid - glossopharyngeal

27

Through which foramen does the chorda tympani exit the skull?:

pterotympanic fissure

28

The chorda tympani enters what fossa to join the lingual nerve?

infra temporal fossa

29

What is the name of the ganglion, which the VII taste fibres of the lingual nerve bypass on their way to the anterior 2/3 of the tongue?:

once they reach the lingual nerve they travel to the submandibular ganglion
and provide innervation to the
- submandibular gland
- sublingual gland
- anterior 1/3 of the tongue

30

After the VII parasympathetic fibres of the lingual nerve synapse at the aforementioned ganglion, what two structures do they go on to innervate?

salivary glands
tongue (anterior 2/3 of the tongue)
