Study Notes

Face

Patient presented with burning/boiling sensation in face.
Possible diagnoses: occipital neuralgia, facial palsy, trigeminal neuralgia, multiple sclerosis.
Pulsations felt above zygomatic arch, in front of the ear are from the superficial temporal artery.
Patient lost cutaneous sensation over angle of mandible; the likely injured nerve is the great auricular nerve.
A branch of the facial artery is the transverse facial artery.
Muscles not supplied by facial nerve: anterior belly of digastric.

Scalp

Nerves supplying occipital belly of occipito-frontalis muscle: posterior auricular branch of facial nerve.
Branch of internal carotid artery supplying scalp: superficial temporal artery.
Veins connecting inside to outside of scalp: emissary veins.
Nerves not supplying scalp: auriculotemporal nerve.
Layers containing vessels and nerves of scalp: skin, connective tissue, aponeurotic, loose areolar tissue layer.
Layer of scalp for cranial cavity infection spread: pericranium.
Arteries supplying scalp (except): infratrochlear artery.
Muscles innervated by greater occipital nerve.
Horizontal skin tension lines of forehead: determined by occipito-frontalis muscle.
Muscle innervated by great auricular nerve.

Skull

Fracture of pterion leads to epidural hematoma; middle meningeal artery is most likely affected.
The only movable bone of the skull: mandible.
Bones of nasal septum: nasal and vomer.
Primary function of facial bones: surround and protect brain, form nasal cavity, orbits, support teeth.
Bones forming norma occipitalis: parietal, temporal, occipital.

Neck Viscera

Fascia enclosing thyroid gland: pretracheal fascia.
Shape of thyroid gland lobes: oval.
Structures that move with swallowing due to enclosure by fascia: carotid sheath, superficial fascia, pretracheal fascia, prevertebral fascia.
Arterial supply of thyroid gland: common carotid artery, superior thyroid, inferior thyroid, thyroidea ima arteries.
Vein draining thyroid into left brachiocephalic vein: inferior thyroid vein.
Apex of thyroid extends up to: oblique line of thyroid cartilage.
Lymphatic drainage destinations: deep cervical and submental nodes, paratracheal and deep cervical nodes, pretracheal and submandibular nodes, submandibular and occipital nodes.
Nerve closely related to medial surface of thyroid gland: recurrent laryngeal nerve.
Where trachea bifurcates: sternal angle.
Structure anterior to trachea: esophagus.
Structure lateral to trachea: carotid sheath.
Fascia covering trachea: pretracheal fascia.
Length of esophagus: 25-30 cm (10-12 inches).
Arterial supply to cervical esophagus (derived from): inferior thyroid artery.
Nerve supply of cervical esophagus (provided by): recurrent laryngeal and sympathetic trunk.
Structure posterior to cervical esophagus: vertebral column.

General

Symptoms from face can spread to the cavernous sinus via the superior ophthalmic vein.
Common facial vein drains into the internal jugular vein.
Sensations from the skin of the lower eyelid are carried by the infraorbital nerve.
Superficial temporal and maxillary veins join to form the retromandibular vein.
The frontal belly of the occipito-frontalis muscle is supplied by the supratrochlear nerve.
Superficial temporal artery is a branch of the external carotid artery.
The facial artery lies anterior to the facial vein.
The facial artery pulsation is palpable against the mandible.
The facial artery divides into supraorbital and supratrocheal branches.
