	~~'''~~Deep Cervical Fascia''' is a fibrous layer of tissue that envelops the structures of the neck, including the [[thyroid gland]], [[trachea]], [[esophagus]], and [[carotid arteries]]. It is part of the [[fascia]], a network of connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, binding some structures together, while permitting others to slide smoothly over each other.		{{DISPLAYTITLE:Deep Cervical Fascia}}

	==~~Structure~~==		==Deep Cervical Fascia==
	The deep cervical fascia is ~~divided into three layers:~~ the ~~superficial~~, ~~middle~~, and ~~deep layers~~.		The '''deep cervical fascia''' is a complex layer of [[fascia]] in the [[neck]] that plays a crucial role in compartmentalizing the neck structures and providing a pathway for the spread of infections. It is an important anatomical structure for medical students to understand due to its implications in [[surgery]], [[anatomy]], and [[pathology]].

	* The '''superficial layer''' (also known as the investing layer) encloses the entire neck and includes the [[~~sternocleidomastoid muscle]] and [[trapezius muscle]]~~.		[[File:Gray384.png\|thumb\|right\|Diagram of the deep cervical fascia]]
	* The '''middle layer''' (or pretracheal layer) envelops the ~~[[viscera~~]] ~~of the neck, such as the thyroid gland, trachea, and esophagus.~~
	* The '''deep layer''' (or prevertebral layer) surrounds the vertebral column and muscles associated with the vertebral column.

	==~~Function~~==		===Anatomy===
	The deep cervical fascia plays a crucial role in the movement and support of the structures within the neck. It allows for the smooth sliding of muscles and organs against each other and provides a protective barrier against infection spreading from the neck to other parts of the body.		The deep cervical fascia is divided into three main layers:

	==~~Clinical Significance~~==		====Investing Layer====
	~~Understanding~~ the ~~anatomy~~ of the deep cervical fascia ~~is essential in surgical procedures involving~~ the neck. ~~It is~~ also ~~significant in~~ the ~~spread~~ of [[~~cervical lymphadenopathy~~]] and [[~~deep~~ neck ~~infection~~]].		The investing layer is the most superficial of the deep cervical fascia. It surrounds the entire neck, enclosing the [[sternocleidomastoid]] and [[trapezius]] muscles. This layer also forms the roof of the [[anterior triangle of the neck]] and the [[posterior triangle of the neck]].

	==~~See Also~~==		====Pretracheal Layer====
			The pretracheal layer is located anteriorly in the neck and is divided into a muscular part and a visceral part. The muscular part encloses the [[infrahyoid muscles]], while the visceral part surrounds the [[thyroid gland]], [[trachea]], and [[esophagus]].

			====Prevertebral Layer====
			The prevertebral layer forms a sheath for the [[vertebral column]] and the associated muscles, such as the [[longus colli]] and [[longus capitis]]. It extends laterally to form the [[axillary sheath]] and surrounds the [[brachial plexus]].

			===Clinical Significance===
			The deep cervical fascia is significant in the spread of infections and [[tumors]] within the neck. Understanding the fascial planes is crucial for surgeons to avoid complications during [[surgical procedures]].

			====Infections====
			Infections can spread along the fascial planes, leading to conditions such as [[Ludwig's angina]] or [[retropharyngeal abscess]]. The fascial layers can act as barriers or conduits for the spread of these infections.

			====Surgical Considerations====
			During surgical procedures, such as [[thyroidectomy]] or [[neck dissection]], knowledge of the deep cervical fascia is essential to avoid damaging vital structures and to ensure proper access to the surgical site.

'''Deep Cervical Fascia''' is a fibrous layer of tissue that envelops the structures of the neck, including the [[thyroid gland]], [[trachea]], [[esophagus]], and [[carotid arteries]]. It is part of the [[fascia]], a network of connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, binding some structures together, while permitting others to slide smoothly over each other.

==Structure==
The deep cervical fascia is divided into three layers: the superficial, middle, and deep layers.

* The '''superficial layer''' (also known as the investing layer) encloses the entire neck and includes the [[sternocleidomastoid muscle]] and [[trapezius muscle]].
* The '''middle layer''' (or pretracheal layer) envelops the [[viscera]] of the neck, such as the thyroid gland, trachea, and esophagus.
* The '''deep layer''' (or prevertebral layer) surrounds the vertebral column and muscles associated with the vertebral column.

==Function==
The deep cervical fascia plays a crucial role in the movement and support of the structures within the neck. It allows for the smooth sliding of muscles and organs against each other and provides a protective barrier against infection spreading from the neck to other parts of the body.

==Clinical Significance==
Understanding the anatomy of the deep cervical fascia is essential in surgical procedures involving the neck. It is also significant in the spread of [[cervical lymphadenopathy]] and [[deep neck infection]].
