Investing Fascia also splits around two salivary glands the _________ and __________, and also splits around two muscles, the __________ and _____________, enclosing them completely.

Back 17

- submandibular and parotid glands

Carotid Sheath

Front 19

The Carotid Sheath houses the _________ and _________ arteries and the _________ vein as well as the __________ nerve

Back 19

- internal carotid and common carotid arteries
- internal jugular vein
- tenth cranial or vagus nerve.

Front 20

______________ is deep to the carotid sheath and is a single midline tube of deep cervical fascia running inferiorly along the neck.

Back 20

Visceral fascia

Front 21

Visceral fascia surrounds the air and food passageways including the

Back 21

trachea, esophagus, and thyroid gland

Front 22

________________ is the term for the visceral fascia located posterior and lateral to the pharnyx that is nearer to the skull.

Back 22

Buccopharyngeal fascia

Front 23

The Buccopharyngeal fascia layer encloses the entire superior portion of the __________ and is continuous with the fascia on the surface of the _____________ muscle

Back 23

- alimentary canal
- buccinator muscle

Front 24

The ____________ is the deepest layer of the deep cervical fascia and covers the vertebrae, spinal column, and associated muscles.

Back 24

Vertebral Fascia

Front 25

The ____________ is the term for the potential spaces that are created between the layers of fascia of the body because of the sheetlike nature of the fascia.

Back 25

Fascial Spaces

Front 26

Fascial Spaces are not actually empty spaces in healthy patients because they contain

Back 26

loose connective tissue.

Front 27

The dental professional must have thorough knowledge of ________________ and the anatomical aspects because they can be involved in infections arising in dental tissues

Back 27

Facial Spaces of Head and Neck

Front 28

The major spaces _____________ include the vestibular spaces of the maxilla and mandible; the canine, parotid, buccal, and masticatory spaces; the space of the body of the mandible; and the submental, submandibular, and sublingual spaces.

Back 28

Facial Spaces of the Face and Jaws

Front 29

Facial Spaces of the Face and Jaws can communicate with each other and with the

Back 29

cervical fascial aspects

Front 30

True or False
Unlike the neck, the spaces of the face and jaws are often defined by arrangement of muscles and bones in addition to fasciae and therefore many of the spaces are not considered fascial spaces.

Back 30

True

Front 31

The major space of the ______________ include: parapharyngeal space, retropharyngeal space, previsceral space

Back 31

Cervical Fascial Spaces

Front 32

True or False
The fascial spaces of the neck can communicate with the spaces of the face and jaws as well as with each other. These spaces connect the spaces of the head and neck with those of the thorax, allowing dental infections to spread to vital organs such as the heart and lungs
