module 7 head and neck 1 Flashcards
Endocrine glands in the head and neck
pineal pituitary hypothalamus thyroid parathyroid
exocrine glands in the head and neck
salivary sweat ceruminous mucous sebaceous
5 layers of scalp. SCALP
S: skin: large number of sebaceous glands
C: connective tissue, passageway for nerves and vessels
A: apicranial aponeurosis: insertion point for occipital-frontalis muscles.
L: loose areolar tissue: allows the 3 above layers to move
P: pericranium, periosteum of cranial bones
arteries and veins of the scalp
supratroclear and supraorbital - both frontal above eyes. superficial temporal - in front of ear posterior auricular - behind ear and up occipital Occipital
anterior lymphatic drainage of scalp
lymph nodes
- parotid
- submandibular
- cervical
posterior lymphatic drainage of scalp
lymph nodes
- posterior auricular
- occipital
Sagittal suture
between the parietal bones
coronal suture
between frontal and parietal bones
lambdoid suture
between parietal and occipital bones
posterior fontanelle closes
2-3 months
sphenoidal fontanelle closes
6 months
mastoid fontanelle closes
6-18 months
anterior fontanelle closes
12-15 months
salivary glands
parotid: anterior to the ear, above the mandible
submandibular: medial to mandible at the angle of the jaw
sublingual: anterior floor of mouth
thyroid location
isthmus lies over tracheal rings 2-4
- should move with swallowing.
thyroid enlargement
bruit may be heard
assess CNVII by asking pt to
smile
frown
wrinkle forehead
puff out cheeks
assess strength of muscles CNV
have pt clench teeth
try to open pt mouth, have them resist.
assess sensation CNV
assess bilaterally on
forehead
cheeks
chin
cardarelli’s sign
palpable pulsations with displacement of thyroid cartilage to the left
- s/s of aneurysm
oliver’s sign
downward tug with upward displacement of cricoid cartilage
ROM in neck
6 directions
- flexion: chin down
- extension: head back
- right lateral
- left lateral
- left rotation
- right rotation
6 steps to feel for nodes of head
- occipital nodes at base of skull
- postauricular: superficial to the mastoid process
- preauricular: just in front of ear
- parotid and retopharyngeal: angle of the mandible
- submandibular: halfway between the angle and the tip of mandible
- submental: midline behind tip of mandible
4 steps to feel for nodes of neck
- superficial cervical: sternocleidomastoid muscle
- posterior cervical: along the anterior border of the trapezius muscle
- deep cervical: deep to the sternocleidomastoid
- supraclavicular: probing deeply in the angle formed by the clavicle and the sternocleidomastoid muscle.
headaches patho
pain in the head
common concern
headaches subjective
description: constant, severe, recurrent
associated: tearing
exposures: meds?
headaches objective
no physical findings in many cases neurologic deficits in some cases abnormal gait papiledema nystagmus
salivary gland tumor patho
tumor in any of the salivary glands, but most commonly in the parotid
salivary gland tumor subjective
slow growing painless lumps, either in front of ear or under jaw
difficulty opening the mouth
tongue numbness or weakness
salivary gland tumor objective
benign tumors usually smooth, malignant often irregular facial weakness fixation of the lump sensory loss ulceration
primary hypothyroidism
thyroid gland produces insufficient amounts of thyroid hormone
secondary hypothyroidism
insufficient TH secretion due to inadequate secretion of either TSH from the pituitary gland or TRH from th hypothalamus
myxedema patho
skin and tissue disorder usually due to severe prolong hypothyroidism
- dec metabolic rate
- > accumulation of hyaluronic acid and chondroitin sulfate in dermis
- deposition of glycosaminoglycan leads to mucinous edema of facial features
myxedema subjective
cognitive impairment, slowed mentation, poor concentration, dec. short term memory, depressed mood
constipation
muscle pain
hearing problems, deafness
myxedema objective
coarse thick skin, thickening nose, swollen lips, puffy eyes.
slow speech
mental dullness, lethargy, mental problems
weight gain
thin brittle hair, with bald patches
graves disease patho
overactive thyroid caused by autoimmune antibodies to TSH receptor
graves disease subjective
palpitations heat intolerance wt loss fatigue inc. appetite, tachycardia
graves disease objective
diffuse thyroid enlargement, prominent eyes
hashimoto disease patho
underactive thyroid caused by autoimmune antibodies against thyroid gland
hashimoto disease subjective
wt gain
nausea
fatigue
hashimoto objective
enlarged nontender smooth thyroid
