2
Q
- Identify the branches of the carotid on a cadaveric image
A
- External carotid a.
- Posterior auricular a.
- Occipital a.
- Internal carotid a.
- Carotid sinus
- Common carotid a.
- Facial a.
- Submental a.
- Facial a.
- Ascending pharyngeal a.
- Lingual a.
- External carotid a.
- Superior thyroid a.
- Superior laryngeal a
3
Q
- Carotid body is what type of receptor?
A
- Chemoreceptor
- Senses O2 content-this information is conveyed centrally by the glossopharyngeal n. (w/ possible involvement of the vagus n.)
4
Q
- Carotid sinus is what type of receptor?
A
- Baroreceptor
- Senses changes in blood pressure
5
Q
- Carotid Sinus Hypersensitivity Syndrome
A
- Pressure over carotid a. causes inappropriate and intense vagal discharge
- Syncope related to head turning, shaving and wearing a tight collar
- Carotid sinus pressure causes a reflexive decrease in heart rate and blood pressure
- Predominantly affects older males
6
Q
- Identify the labeled branches of the subclavian a.
A
- Deep cervical a.
- Vertebral a.
- Ascending cervical a.
- Inferior thyroid a.
- Thyrocervical trunk
- Subclavian a.
7
Q
- Identify the structure
A
- Spinal accessory n. (XI)
8
Q
- Identify the branches of the subclavian
A
- Ascending cervical a.
- Inferior thyroid a.
- Vertebral a.
- Thyrocervical trunk
- Subclavian a.
- Transverse cervival a.
- Deep cervical a.
9
Q
- Identify the veins
A
- Posterior auricular v.
- External jugular v.
- Internal jugular v.
- Transverse cervical v.
- Anterior jugular v.
10
Q
- Subclavian v. puncture
A
- Often where central lines are placed
11
Q
- Internal jugular v. puncture
A
- Used for diagnostic of therapeutic purposes
- Right internal jugular v is preferred because it is longer and straighter
12
Q
- Central line placement
A
- Usually done on the subclavian v.
- Used to administer medications, nutrition, and for measuring central venous pressure
13
Q
- External jugular venous pressure
A
- The External Jugular V. may serve as an “internal barometer” since when venous pressure rises the External Jugular V. is much more prominent along it’s course on the lateral Neck.
- This can be used a s a diagnostic tool for conditions such as heart failure, Superior Vena Cava obstruction, enlarged Supraclavicular Lymph Nodes or increased intrathoracic pressure.
14
Q
- Identify the superficial lymph nodes
- Where do they drain?
A
- Superficial parotid LNs
- Anterior superficial LNs
- Occipital LNs
- Mastoid LNs
- Lateral Superficial LNs
Drain into the deep LNs
15
Q
- Identify the deep LNs
A
- Submental nodes
- Infrahyoid nodes
- Pretracheal nodes
- Thyroid nodes
- Paratracheal nodes
- Deep parotid nodes
- Superior deep nodes
- Submandibular nodes
- Retropharyngeal nodes
- Inferior deep nodes
16
Q
- Superficial nodes drain into _ nodes
A
- Inferior deep LNs
