Q

upper facial muscles -innervation

Study These Flashcards
A

~ Upper facial muscles receive bilateral cortical innervation (both sides of the brain)

~ Brain injury – upper face is unaffected

25
lower facial muscles - innervation
~ Lower facial muscles receive contralateral cortical innervation (innervation from one side of the brain) ~ Brain injury – lower face is affected on the opposite side to where the damage is
26
tongue components
- body - tip - blade - dorsum - root (base)
27
tongue - tip (function)
- most anterior part - (t, d, z) sounds - pushes food for swallowing
28
Oral part (palatal surface)
- anterior 2/3 - tip, blade & dorsum composed of - Foramen cecum - Sulcus terminalis - Median sulcus - papillae
29
Pharyngeal part/surface
- posterior 1/3 - root composed of ~ Lingual tonsil (covers entire surface) ~ Epiglottis ~ Gloss epiglottic folds
30
types of papillae
- circumvallate - floiate - fungiform - filiform
31
tongue - sensory innervation
Mandibular nerve (CN V3) - Lingual (tongue) nerve Facial nerve (CN VII) - chorda tympani – joins lingual nerve to reach anterior 2/3 of tongue Glossopharyngeal nerve (CN IX) - Innervates posterior third of the tongue - (taste & general sensation)
32
extrinsic muscles of the tongue
- alter its position
33
intrinsic muscles of the tongue
- alter its shape
34
what nerve is the tongue innervated by
- all muscles = HYPOGLOSSAL (CNXII) - except for the palatoglossus which is innervated by the vagus nerve
35
tongue movements
- shortening & elongating - narrowing & widening - curling & flattening - elevation & depression - protrusion & retrusion
36
intrinsic muscles of the tongue
~ four paired muscles ~ alter the shape of the tongue ~ important for speech
37
intrinsic muscles of the tongue components
- Superior longitudinal - inferior longitudinal - transverse (elongates) - vertical (widens/flattens)
38
superior & inferior longitudinal
- both shorten tongue - SL = curls tip & sides superiorly - IL = curls tip inferiorly
39
transverse - tongue
elongates & narrows tongue
40
vertical tongue
widens & flattens tongue
41
extrinsic muscles of the tongue
~ Originate OUTSIDE the tongue ~ insert within the tongue ~ alter the position of the tongue
42
extrinsic muscles of the tongue components
- genioglossus - hyoglossus - styloglossus - palatoglossus
43
genioglossus
- Superior mental spine of mandible - Depresses, protrudes tongue
44
hyoglossus
- body & greater horn of hyoid bone - depresses & retracts tongue
45
styloglossus
- Styloid process of temporal bone - retracts tongue - curls sides superiorly for swallowing
46
palatoglossus
- soft palate - elevates posterior tongue
47
suprahyoid muscles
- 4 muscles paired - Located superior to the hyoid bone - elevate the hyoid bone when swallowing
48
Suprahyoid muscles
- mylohyoid - geniohyoid - stylohyoid - digastric
49
mylohyoid
Origin - Mylohyoid line of mandible Insertion - Body of hyoid bone Actions - Elevates hyoid bone - Elevates floor or oral cavity Innervation - indirect branch of mandibular nerve (CN V3)
50
Geniohyoid
Origin - Inferiors mental spine of mandible Insertion - Body of hyoid bone Actions - Elevates hyoid bone - Pulls hyoid bone anteriorly Innervation -C1 spinal nerve, via hypoglossal nerve (CN XII)
51
Stylohyoid
Origin - styloid process of temporal bone Insertion - Body of hyoid bone Actions - Elevates hyoid bone & Pulls it posteriorly Innervation - branch of facial nerve (CNVII)
52
digastric
origin - anterior belly = digastric fossa of mandible - posterior belly = mastoid notch of temporal bone insertion - body of hyoid bone via intermediate tendon actions - elevates hyoid bone - depresses mandible against resistance innervartion - Anterior belly = indirect branch of mandibular nerve (CN V3) - Posterior belly = Branch of facial nerve (CN VII)
53
velum soft palate
- Forms part of the roof of the oral cavity - can be depressed, elevated and tense
54
Musculo-membranous structure:
- Anterior 1/3: palatine aponeurosis (connective tissue) - Posterior 2/3: palatine muscles - important for closing off the upper airway (nasopharynx) during Swallowing - Velopharyngeal (or palatopharyngeal) closure
55
palatine muscles
- Tensor veli palatini - levator veli palatini - palatglossus - palatopharyngeus - musculus uvulae
56
palatine muscles - elevators
- LVP = elevates velum - musculus uvulae = elevates & shorterns uvula
57
palatine muscles - depressors
- Palatoglossus = depresses velum - Palatopharyngeal = elevates pharynx in swallowing
58
tensors
- TVP = tenses velum & opens auditory tube during swallowing
59
palatine muscles
- all palatine muscles (except TVP) are innervated by the vagus nerve (CN X) TVP = innervated by (CN V3)
