What arteries supply the Scalp?

Occipital, Posterior Auricular, Superficial Temporal, Supraorbital, and Supratrochlear

What veins drain the face?

Primarily, Facial Vein

Describe the Venous Drainage of Facial Vein

Angular --> Facial --> Deep Facial drains Pterygoid Venous Plexus into Facial --> Internal Jugular

Describe Formation of External/Internal Jugular Vein

Superficial Temporal and Maxillary Vein = Retromandibular
Posterior Retromandibular + Posterior Auricular = External JV
Anterior Retromandibular + Facial Vein = IJV

What other veins drain the face?

Occipital, Superficial Temporal, Supraorbital, Supratrochlear, and Deep Temporal Veins

What does the skin of the scalp contain?

sweat, sebaceous glands, and hair follicles

What does the P in scalp stand for?

Pericranium

What is the parotid sheath derived from?

Investing Layer of Deep Cervical Fascia

Where does the Parotid Gland enter the mouth?

Across from the 2nd molar in the top of the mouth

Where is the parotid gland located?

Parotid bed between Ramus of the Mandible and Mastoid Process

What is embedded in the Parotid Gland from Superficial to Deep?

Parotid Plexus of Facial Nerve, Retromandibular Vein, and External Carotid Artery

What is the Innervation to the Parotid Gland?

Greater Auricular Nerve (C2,C3) Sensory
Auriculotemporal Nerve (CN V3) Sensory
Glossopharyngeal Nerve (CN IX) para/pre

What is the course the para/pre fibers take from the Glossopharyngeal Nerve (CN IX)?

para/pre to the Otic Ganglion --> para/post course with Auriculotemporal Nerve to Parotid Gland

Where do the Sympathetic Fibers derive from?

External Carotid Nerve Plexus

Where does Lymph Initially drain to in the Face and Scalp?

Superficial Ring

What lymph nodes are in the superficial ring?

Submental, Submandibular, Parotid, Mastoid, and Occipital
Superficial Cervical may or may not be grouped

Where does lymph from the Superficial Cervical Lymph Nodes drain?

Deep Cervical Lymph Nodes

Where are the deep cervical lymph nodes found?

Along the Internal Jugular Vein

Where does Lymph flow from the Deep Cervical Lymph Nodes?

Thoracic Duct (L) or Right Lymphatic Duct (R)

What is the general principal for lymph flow?

Superficial to Deep and Superior to Inferior

lymph from lateral face drains to?

Parotid Lymph Nodes

lymph from deep parotid lymph nodes drains to?

deep cervical lymph nodes

lymph from upper lip and lateral lower lip drains to?

submandibular lymph nodes

lymph from chin and central part of lower lip drains to?

submental lymph nodes

What is the function of the Anterior Belly of the Occipitofrontalis muscle?

Retract/Protract the Scalp and Raise the Eye Brows

What provides cutaneous sensory innervation to the face?

Trigeminal Nerve (CN 5)

What provides motor innervation to the facial msucles?

Facial Nerve (CN 7)

What provides motor innervation to the muscles of mastication?

Mandibular Nerve (CN V3)

What are the three large groups of peripheral processes off the Trigeminal Ganglion?

1. Opthalmic Nerve (V1)

Where does the Facial Nerve exit the Cranium?

Stylomastoid Foramen

What muscles does the Fascial Nerve innervate?

auricular, fascial expression, posterior belly of the digastric muscle, and stylohyoid muscles

Where does the Facial Artery originate?

External Carotid Artery

What are the branches off the Facial Artery?

Superior Labial Artery

External Carotid Artery

What branches off the Superficial Temporal Artery?

Transverse Facial Artery

The Superficial Temporal and Transverse Facial supply what areas of the Face?

Temporal Region, Parotid Gland, skin of the face, and will anastomose with the facial artery
