Focuses on the cranium, face, thyroid gland, and lymph nodes contained within the head and neck
Normocephalic
Normal head size
Cranium bones
Frontal (1 bone)
Parietal (2 bones)
Temporal (2 bones)
Occipital (1 bone)
Ethmoid (1 bone)
Sphenoid (1 bone)

Maxilla (2 bones)
Zygomatic (cheek) (2 bones)
Inferior chonchae (2 bones)
Nasal (2 bones)
Lacrimal (2 bones)

Infants
Fontanels ("soft spots") – anterior and posterior fontanels
Voluntary head control should be present by about 6 months of age
Neck muscles and cervical vertebrae
Sternocleidomastoid muscle – rotates and flexes the head
Trapezius muscle – extends the head and move the shoulders
11th cranial nerve (spinal accessory nerve) – responsible for muscle movements that permits shrugging of the shoulders
Cervical vertebrae – C1(atlas), C2 (axis) up to C7
Neck blood vessels
Internal and/or external jugular vein
Carotid arteries
Nursing consideration
Avoid bilaterally compressing the carotid arteries when assessing the neck as it might reduce blood supply to the brain
Thyroid gland
Largest endocrine gland producing thyroid hormones (T3, T4 and Thyrocalcitonin) that increase metabolic rate of most body cells
Thyroid gland palpation
Points of reference - the trachea, cricoid cartilage and the thyroid cartilage ("Adam's apple" for male clients)
Common thyroid disorders
Hypothyroidism
Hyperthyroidism (thyrotoxicosis)
Lymph nodes
They filter lymph - a clear substance composed mostly of excess tissue fluid which may or may not contain bacteria or tumor cells; they also produce lymphocytes and antibodies as defense against foreign microbes of substances
Lymph nodes
Normally not palpable but may become overwhelmed with filtrates or microbes leading to painful swelling on palpation
Types of lymph nodes
Preauricular
Postauricular
Tonsillar
Occipital
Submandibular
Submental
Superficial cervical
Posterior cervical
Deep cervical
Supraclavicular
T3
Stimulates the nervous system resulting in increased wakefulness, alertness, and responsiveness to external stimuli. Active, can impact your cells and your metabolism.
T4
Increases numerous enzymes that produce energy for the body. Inactive, it doesn't affect your body's cells. Converts into T3.
Thyrocalcitonin
Also called calcitonin, lowers the levels of calcium and phosphate in the blood and promotes the formation of bone.
