1

Cranial Bones

Frontal, Parietal, Occipital, Temporal

2

2 pairs of salivary glands are accessible to examination on the face

Parotid glands are in cheeks over mandible, anterior to and below ear; the largest of salivary glands, they are not normally palpable
Submandibular glands beneath mandible at angle of jaw

3

Structures of the head

Cranial bones
Sutures
Facial bones
Facial muscles
Salivary glands

4

Internal carotid branches off wearing and supplies what?

Branches off common carotid and runs inward and upward to supply the brain

5

External carotid supplies what?

face, salivary glands, and superficial temporal area

6

Cranial Nerve XI

Innervates major neck muscles sternomastoid and trapezius

7

Sternomastoid

enables head rotation and flexion and divides each side of neck into two triangles: anterior and posterior triangles

8

Thyroid gland

Synthesizes and secretes thyroxine (T4) and triiodothyronine (T3), which are hormones that stimulate rate of cellular metabolism

9

Thyroid gland location

an important endocrine gland straddles trachea in middle of the neck
The gland has two lobes, connected in middle by a thin isthmus and above that by the cricoid cartilage or upper tracheal ring

10

What are you looking for when you are looking at the thyroid, trachea, carotid arteries and lymph nodes

Thyroid gland: looking for right size, no tenderness
Trachea: central
Carotid arteries: palpable, even pulse, strength of pulse
Lymph nodes: no swollen, not palpable (sometimes there is one in children)

11

Lymphatic system function

extensive vessel system, is major part of immune system, which detects and eliminates foreign substances from body

12

Where is the greatest supply of the lymph nodes?

Head and Neck and Breasts
Nodes are small, oval clusters of lymphatic tissue that filter lymph and engulf pathogens, preventing potentially harmful substances from entering the circulation

13

Locations and names of lymph nodes

-Preauricular, in front of ear
-Posterior auricular (mastoid), superficial to mastoid process
-Occipital, at base of skull
-Submental, midline, behind tip of mandible
-Submandibular, halfway between angle and tip of mandible
-Jugulodigastric, under angle of mandible
-Superficial cervical, overlying sternomastoid muscle
-Deep cervical, deep under sternomastoid muscle
-Posterior cervical, in posterior triangle along edge of trapezius muscle
-Supraclavicular, just above and behind clavicle, at sternomastoid muscle

14

Where do lymph nodes drain to?

Cervical chain

15

Cephalohematoma

is when there's bleeding in the brain on one side (it doesn’t pass the suture lines) that leads to a collection of blood shaping the head, but the breakdown of blood vessels can lead to jaundice.

16

Caput Succadaneum

general fluid buildup, usually more dispersed

17

When do babies have control of their head?

at 3 - 4 months

18

Is head or chest larger for newborn at birth

Head is bigger

19

Pregnant woman consideration with thyroid

Thyroid gland is slightly enlarged during pregnancy as a result of hyperplasia of the tissue

20

Aging adult consideration with skin and face

Facial bones and orbits appear more prominent
Facial skin sags as a result of decreased elasticity, decreased subcutaneous fat and decreased moisture in the skin

21

Palpebral Fissures

opening between top and bottom eyelids

22

Nasolabial folds

Smile lines

23

How to palpate temporomandibular joint

As the person opens the mouth, and note normally smooth movement with no limitation or tenderness

24

Cranial nerve XI

spinal accessory

25

How to test muscle strength in the neck

Push on shoulders and they push against resustance
Have them turn their head towards you to press against your hand and do to the other side

26

What to notice in jugular veins?

Distension because distension can mean heart failure

27

Way to inspect and palpate the Thyroid gland

Posterior approach
Anterior approach
Auscultate (with bell of stethoscope) thyroid for bruit (Abnormal blood flow to the area usually caused by a an obstruction), if enlarged

28

How to examine Lymph Nodes

Using a gentle circular motion of finger pads, palpate lymph nodes
Beginning with preauricular lymph nodes in front of ear, palpate the 10 groups of lymph nodes in routine order

29

Are lymph nodes normally palpable in children

Yes they are, usually do to ear infections

30

During what semester does chloasma usually show in a pregnant mom

Second semester
