Q

Infrahyoid Muscles function?

A

lower the the hyoid bone during speaking and swallowing

17
Q

What separates the carotid triangle from the muscular triangle

A

Superior belly of the omohyoid muscle

18
Q

What cervical compartment is formed by the carotid sheath?

A

The neurovascular compartment

19
Q

The neck is divided into compartments. Surrounded by a musculofascial collar. What is found in the vertebral compartment?

Visceral compartment?

Neurovascular compartment?

Muscular compartment?

A

Vertebral compartment contains the muscles of the vertebral column.

Visceral compartment contains the Pharynx, larynx, esophagus, trachea, and glands.

Neurovascular compartment contains blood vessels and nerves.

Muscular compartment contains muscles.

20
Q

Sternocleidomastoid muscle divides neck:

A

Anterior cervical triangle

Posterior cervical triangle

21
Q

What is the posterior cervicle triangle?

A

It is the space between the muscles and the clavicle.

22
Q

The anterior scalene muscle is considered a ______ muscle.

A

A Landmark muscle.

The subclavian vein lies anterior to the muscle and the subclavian artery lies posterior to the muscle along with the subclavian artery. The subclavian artery and brachial plexus separates the anterior and middle scalene muscles.

23
Q

Which triangle is the ONLY unpaired triangle of the neck?

A

The submental triangle is the only unpaired triangle of the neck.

24
Q

Where are the palantine tonsils located?

A

Palantine tonsils are located in the tonsillar bed on the lateral walls between the anterior and posterior fold.

25
Q

What is the isthmus of fauces?

A

It is the entrance into the fauces or throat formed by the anterior tonsillar arch (pillars).

26
Q

What is the significance of the piriform recess?

A

Ingested objects can become trapped or lodged in the recess.

27
Q

What is the significance of the median cricothyroid ligament?

A

It is the entrance point for an emergency airway procedure

28
Q

What is the difference between a cricothrotomy and a tracheotomy?

A

Cricothrotomy is the incision of the skin and the median cricothyroid ligament for emergency entrance into the airway. Tracheotomy is the incision of the skin and membrane separating the cartilages of the trachea for emergency entrance into the airway.

29
Q

What is the rima glottidis?

A

small-slit opening between the vocal folds.

30
Q

Vocal ligaments vs. vestibular folds?

A

The vocal ligaments produce sound, while closure of the vestibular folds prevents the movement of air into and out of the larynx.

Closure of the vestibular folds increase abdominal pressure for exercise and excretory functions.
