skeletal structure
cranium is composed of 22 bones supporting the soft tissue structures of the head
anatomy of head
contains:
- muscles
- blood supply
- nerve supply
- salivary glands
blood supply to the head
- carotid arteries
- temporal artery
- internal and external jugular veins
nerve supply to face
cranial nerve V - facial nerve
salivary glands
parotid
submandibular
sublingual
CN VIII can interfere with
vestibulocochlear nerve can interfere with balance
facial nerve innervates ear which can
interfere with balance
facial muscles are responsible for
all movement of the face
CN V responsible for movement
any injury to ear
effects coordination and hearing
brainstem injury
very disoriented and confused
anatomy of the nose
- allows air to enter the respiratory tract
- primary organ for smell
- nerve and blood supply consits of CN 5, 7, 9, and 10, internal and external carotid arteries, and kiesselbach plexus
- lymphatic drainage
kiesselbach plexus
blood supply to the nose, most common for nose bleeds
ethmoid bone
only bone separating brain from nose
if ethmoid bone breaks
risk for infection, leakage of cerebrospinal fluid
sigmoid bone
helps protect against infection
sinuses all come together to form
osteomeatal complex
sinus anatomy
frontal sinus
maxillary sinus
ethmoid sinus
most common site of anterior nose bleeds
kiesselbach
common in cases of trauma, should stop with pressure
mouth
- eat, taste, chewing, speech
- very vascular tongue
- salivary glands
- teeth and gums
vascularity of tongue allows for
sublingual meds
quick acting meds
tongue
- muscle (most vascular muscle)
- front 2/3 should be covered in tastebuds
salivary glands
- produce 2-4 L/day of saliva
- affected by aging and certain meds, xerostomia, chemo
issues with salivary gland causes
harder to swallow food, and protection
xerostomia
dry mouth
