Question

What fascias form the carotid sheath?

1) The prevertebral fascia
2) The carotid fascia
3) The parotid fascia
4) d) The pharyngeal fascia

Answer 1

1) The prevertebral fascia, 2) The carotid fascia, 3) The parotid fascia

The carotid sheath is formed by the prevertebral fascia, carotid fascia, and parotid fascia.

Step-by-step explanation:

The carotid sheath is a connective tissue structure located in the neck that contains the common carotid artery, internal jugular vein, and vagus nerve. It is formed by three fascias:

1. The prevertebral fascia: It surrounds the vertebral column and forms the posterior part of the carotid sheath.
2. The carotid fascia: It surrounds the common carotid artery, internal jugular vein, and vagus nerve and forms the middle part of the carotid sheath.
3. The parotid fascia: It surrounds the parotid gland and forms the anterior part of the carotid sheath.

So the correct answer would be options 1), 2), and 3).
