Face, Scalp and Parotid Gland Flashcards
Muscles of Mastication?
Massiter, temporalis, medial and lateral (abduction) pterygoid
What are the 5 layers of the skull?
Skin, CT, Aponeurosis, Loose CT and Pericranium
What muscles does the apopneurosis connect
Frontalis and occipitalis
Function of the loose CT
Allows the skin to slide over the pericranium
Structure of Face
Similar to SCALP yet no loose CT and Apopneurosis is muscle
Characteristics of Muscles surrounding orrifaces
Will originate at bone and attach t skin to allow movement and convey facial expression
Branches of External Carotid Artery before terminal branches
Before entering the cranium will give off 6 branches 1. Superior Thyroid 2. Lingual 3. Facial 4. Occipital 5. Posterior Auricular 6. Ascending Pharyngeal Terminal Branches = Superior temporal and Maxillary
Branches of ECA inferior to superior
From inferior to superior
- Ascending pharengeal
- Superior thyroid
- Lingual
- Occipital
- Facial
- Posterior auricular
- Maxillary
- Superficial temporal
What foramen does the middle meningeal artery pass through? and what does it branch off? what does it supply?
The Foramen Spinosum and branches from maxillary artery (3rd branch) and will supply the dura mater
What does the superficial temporal supply?
Scalp in the CT layer
What branches supply the face but don’t arise from ECA?
Supra-orbital artery and Supratrochlear artery
and both branch off the opthalmic artery from the ICA
What are the lymph nodes of the face
- Submental
- Submandibular
- Pre-auricle and parotid nodes
- Mastoid nodes
- Occipital nodes
Define the location of the Parotid
Ramus of mandible anteriorly and the mastoid process posteriorly, will then pass over the massiter and pierce the buccinator to enter the mouth
