What is prevertebral?

What is Pretracheal?

The pretracheal (ie, anterior visceral) space is enclosed by the visceral division of the middle layer of the deep cervical fascia and lies immediately anterior to the trachea. It extends from the thyroid cartilage to the superior mediastinum.

• Superficial Fascia, which is mostly associated with the skin;
• Deep Fascia, which is mostly associated with the muscles, bones, nerves and blood vessels; and.
• Visceral (or Subserous) Fascia, which is mostly associated with the internal organs.

What is prevertebral layer?

Prevertebral layer As the name implies, this layer of the deep cervical fascia forms a tubular sheath for the vertebral column and the muscles (such as the longus colli and longus capitis) associated with the vertebral column.

What is fascia made of?

Fasciae are similar to ligaments and tendons as they are all made of collagen except that ligaments join one bone to another bone, tendons join muscle to bone and fasciae surround muscles or other structures. The video below gives a fascinating introduction to fascia.

What is fascia Colli?

Anatomical terminology. The deep cervical fascia (or fascia colli in older texts) lies under cover of the platysma, and invests the muscles of the neck; it also forms sheaths for the carotid vessels, and for the structures situated in front of the vertebral column.

What fascia covers the thyroid?

The thyroid gland is ensheathed by the visceral fascia, a division of the middle layer of deep cervical fascia, which attaches it firmly to the laryngoskeleton. The anterior suspensory ligament extends from the superior-medial aspect of each thyroid lobe to the cricoid and thyroid cartilage.
