|
the platysma muscle is located in which layer of neck fascia?
|
superficial
|
|
|
What layers comprise the deep cervical fascia?
|
Superficial (investing) layer
Pretracheal Prevertebral Carotid Sheath |
|
|
What structures are found within the superficial layer of the deep cervical fascia
|
the superficial layer of the deep cervical fascia envelops the trapezius and SCM's
|
|
|
What two layers comprise the pretracehal fascia of the deep cervical fascia? What structures are found within these?
|
muscular layer-encoles infrahyoid muscles
visceral layer-encloses thyroid and parathyroids, traceha, and esophagus, contains the buccopharynegeal fascia which is the posterior section of the visceral layer that separates the esophagus from the prevertebral fascia |
|
|
Which structures are contained in the prevertebral layer of the deep cervical fascia
|
the prevertebral fascia envelops the vertebral column and associate muscles (scalenes) and the roots of the brachial and cervical plexuses, within this layer is the alar fascia which is the anterior lamina of the prevertebral fascia
|
|
|
which structures are contained within the carotid sheath of the deep cervical fascia
|
internal carotid a. , vagus n., common carotid, internal jugular v.
hint: I see 10 CC's in the IV |
|
|
Where is the retropharyngeal space? What are it's borders? How far would an infection go if it dissected this space
|
the retropharyngeal spaces is a potential space between the buccopharyngeal (of the visceral layer) and the alar (of the prevertebral layer) layers of deep cervical fascia. An infection can funnel down all the way into the thoracic cavity because the fascia layers are continuous
|
|
|
What is the isthmus of the thyorid gland
|
connection between lobes, tightly attached to trachea rings 2 and 3
|
|
|
What are the borders of the anterior triangle
|
SCM, Mandible, Midline of neck
|
|
|
What are the 4 subtriangles of the anterior triangle
|
1. muscular
2. carotid 3. submandibular 4. submental |
|
|

Contents? |
Borders- hyoid, superior belly of omohyoid, SCM, midline of neck
contents-infrahyoid muscles, thyroid and parathyroid glands |
|
|
What are the border of the carotid triangle of the anterior triangle?
Contents? |
Borders- post. belly of digastric, superior belly of omohyoid, SCM

|
|
What are the borders of the submandibular triangle of the anterior triangle?
Contents? |

|
|
What are the borders of the posterior triangle
|

|
|
|
what are the two subtriangles of the posterior triangle
|
1. omoclavicular
2. occipital |
|
|
What are the borders and contents of the omoclavicular triangle of the posterior triangle
|
Borders: inferior belly of omohyoid, clavicle, SCM
Contents- subclavian artery, subclavian v. , suprascapular a. , suprascapular lymph nodes |
|
|

Contents- external jugular v., branches of cervical plexus, accessory n., trunks of brachial plexus, transverse cervical a., cervical lymph nodes, phrenic n. |
|
|
What is the pretracheal fascia continuous with as it leaves the neck
|
the pretracheal fascia extends inferiorly from the hyoid bone into the thorax where it blends with the fibrous pericardium
|
|
|
The borders of the retropharyngeal space are the buccopharyngeal fascia anteriorly, the alar fascia posteriorly, and the carotid sheath laterally. What is the inferior border of this space?
|
The inferior border is T1/T2 where the pretracheal fascia becomes continuous with the fibrous pericardium of the heart
