18
Q

what is the terminal branches of the ECA

A

superficial temporal artery
maxillary artery

19
Q

what does the superficial artery supply

A

the scalp and face

20
Q

what does the maxillary artery supply

A

the teeth and head

21
Q

what does the superficial thyroid artery supply

A

the thyroid gland
the larynx

22
Q

what are the pulse point

A

the carotid arteries
the superficial temporal artery
the facial artery

23
Q

where could you feel the carotid arteries pulse

A

1 at the bellow angle of mandible
2 on the side of the neck
3 infront of the sternomastoid muscle

24
Q

where to feel the facial artery

A

against the base of mandible

25
Q

where to feel superficial artery

A

anterior to the ear
against zygomatic arch

26
Q

where does the internal jagular vein start

A

at the jagular FORAMEN

27
Q

what is the course of IJV

A

it descends in the neck deep to sternomastoid
it descends with the carotid sheath along the CCA , ICA and the last 4 cranial nerves

28
Q

where does the IJV end

A

it UNITES with subclavian vein to form brachiocephalic vein

29
Q

what are the TRUBUTARIES of IJV

A

1 inferior petrosal sinus
2 common fascial vein
3 lingual vein
4 pharyngeal vein
5 superior thyroid vein
6 ** middle** thyroid vein

30
Q

what is the function of IJV

A

insetion of central venous catheter

31
Q

what is the EJV formed of

A

posterior auricular vein
posterior division of retro mandibular vein { posterior division of posterior facial vein }

32
Q

what is the course of EJV

A

it desceds superficial to sternomastoid
it pierces the deep fascia of the neck ABOVE clavicle

33
Q

where is the end of EJV

A

it drains in sub clavian vein

34
Q

what are the differences between the IJV and EJV

A

internal is deep to sternomastoid but external is superficial to sternomastoid
internal unites with subclavian V but external drains in sub clavian vein
internal is in the carotid sheath but external is not in the carotid sheath
