  • Depressor anguli oris
17
Q

What are the two main muscles of the eyelids

A
  • Orbicularis Oculi
  • Frontalis
18
Q

What muscle opens the eyelid

A

Frontalis

19
Q

What muscle closes the eyelid

A

Orbicularis oculi

20
Q

Key muscle involved in blowing air from mouth eg whistling

A

Buccinator

21
Q

Why is the parotid gland painful when inflamed?

A

Encased by a tough fascia

22
Q

Describe the location of the parotid gland

A
  • Anterior to the external acoustic meatus
  • Wedged between mandible and masseter anteriorly and SCM posteriorly
23
Q

The parotid gland pierces through what muscle before opening into the mouth opposite the brown of the second upper molar

A

Buccinator

24
Q

What structures are found within the parotid gland

A
  • Facial nerve
  • Retromandibular vein
  • External carotid artery
25
Q

Parasympathetic activation of the parotid gland (increase saliva) is via what nerve?

A

CN IX

Glosso pharyngeal

26
Q

Symptathetic innervation of the parotid gland (decrease in saliva) is via what nerve

A

Superior cervical ganglion

27
Q

There are many midline anastomoses between facial artery branches. What is the implication of this

A

Cut arteries bleed from both ends

28
Q

What are the main artery and vein which supply the face

A

Facial Artery

Facial Vein

29
Q

Hw can bacteria get into the deep brain via the face?

A

The facial vein communicates with the opthalmic vein at the medial canthus of eye, and the pterygoid plexus. Both drain into the cavernous sinus.

Q

Masseter Muscle:

  • Origin
  • Insert
  • Action
  • Nerve Supply
A
  • Originates zygomatic arch
  • Inserts lateral ramus of mandible inc. angle
  • Elevates mandible
  • Masseteric trunk V3
31
Q

Temporalis Muscle:

  • Origin
  • Insert
  • Action
  • Nerve supply
A
  • Floor of temporal fossa
  • Converges to a tendon which runs deep to the zygomatic arch then attaches to coronoid process and anterior border of ramus of mandible
  • Elevates mandible
  • Deep temporal branch V3
32
Q

Blood supply for the TMJ:

A

Maxillary and superficial temporal arteries and veins

33
Q

Sensory for the TMJ:

A

Auriculotemporal nerve of V3

34
Q

What are the three ligaments which attach the temporal bone to the mandible at the TMJ?

A
  • Lateral ligament
  • Spenomandibular ligament
  • Stylomandibular ligament
35
Q

What are the three articular surfaces involved in the TMJ

A
  • Articular tubercle
  • Mandibular fossa (temporal bone)
  • Condyle of the mandible
36
Q

What lines the TMJ capsule

A

Synovial membrane

37
Q

Where does the sphenomandibular ligament attach on the mandible?

A

Lingula
