Deep Cervical Fascia
The deep cervical fascia is a layer of connective tissue that envelops the neck muscles and other structures. It is a continuation of the pretracheal fascia and extends from the hyoid bone to the clavicle and scapula.
Attachments and Modifications
-
The deep cervical fascia attaches to the following structures:
- Hyoid bone
- Thyroid cartilage
- Laryngeal cartilages
- Trachea
- Esophagus
- Prevertebral muscles
- Sternocleidomastoid muscle
- Trapezius muscle
- Cervical vertebrae
-
The deep cervical fascia has the following modifications:
- Pretracheal fascia
- Prevertebral fascia
- Carotid sheath
- Alar fascia
- Occipital fascia
Applied Anatomy
- The deep cervical fascia plays a crucial role in the movement and stability of the neck.
- It provides support to the trachea, esophagus, and other vital structures.
- The fascia also aids in the transmission of forces between the hyoid bone and the laryngeal cartilages.
- The carotid sheath, a modification of the deep cervical fascia, encloses the common carotid artery, internal jugular vein, and vagus nerve.
- Injuries to the deep cervical fascia can lead to hemorrhage, nerve damage, and other complications.
Key Points
The deep cervical fascia is a complex layer of connective tissue that plays a vital role in the anatomy of the neck. Its attachments and modifications are crucial for the movement and stability of the neck, and its applied anatomy has significant implications for clinical practice.
