0:10 What is a Fascia?
2:22 Content
3:04 Temporal Fascia
4:06 Masseter Fascia and Parotid Fascia
4:51 Buccopharyngeal Fascia
5:59 Cervical Fascia
Fascia Functions:
- Stabilizes and separates muscles from other internal organs
- Form compartments
- Passage for Nerve, Blood vessels and lymph
- Storage medium for fat and water
- Three types of Fascia:
β Superficial Fascia
β Deep Fascia
β Visceral Fascia
Fascia of the Head
- Temporal Fascia
β Starts at the Superior Temporal Line
β Splits into 2 Layers
- Deep Layer
Lamina Profunda
- Superficial Layer
Lamina superficialis
- Parotid Fascia
β Covers the Parotid Gland
- Masseteric Fascia
β Covers the Masseter Muscle
- Buccopharyngeal Fascia
β Covers buccinator muscle
β Goes behind the pharynx
β Fuses with pterygomandibular raphe
Fascia of the Neck
- Cervical Fascia
β Superficial Layer
- Covers the surface of the neck
- Envelops the Sternocleidomastoid and Trapezius
- Platysma is superficial to the fascia
β Pretracheal Layer
- Envelops infrahyoid muscles
- It forms the Carotid Sheath
(surrounds neurovascular bundle)
β Prevertebral Layer
- Covers the deep cervical muscles
