2. Artery
Veins

3. Two main arteries:
External Carotid Artery
Subclavian Artery

4. Terminal branch of the
common carotid artery
Level of the upper border
of the thyroid cartilage
Terminates within the
parotid gland at the level
of the neck of the
mandible

5. Branches:
Ascending Pharyngeal artery.
Superior thyroid artery.

Posterior auricular artery
Occipital artery
Superficial temporal artery
Maxillary artery

6. Ascending
pharyngeal artery
Occipital artery
Posterior auricular
artery
Superior thyroid artery
Lingual artery
Facial artery

7. Ascending
pharyngeal artery
Ascends the wall of
the pharynx
Supplies pharynx
and palatine tonsil

8. Superior thyroid
artery
Passes along with
the external
laryngeal nerve
Supplies thyroid
gland
Gives superior
laryngeal artery

9. Lingual artery
Passes towards
the tongue deep to
the hyoglossus
muscle
Divided into three
parts

10. Facial Artery
Branches in the neck
Ascending palatine
artery
Tonsillar artery
Submental artery
Glandular branches
Branches in the face
Inferior labial artery
Superior labial artery
Lateral nasal artery

11. Posterior auricular
artery
Passes posteriorly
along the upper
border of the
posterior belly of
the digastric
muscle
Supplies the
external ear and
posterior quadrant
of the scalp

12. Occipital artery
Passes posteriorly along the
lower border of the posterior
belly of the digastric muscle
Supplies posterior quadrant
of the scalp

13. Occipital artery

14. Superficial temporal artery
Terminal branch of the
external carotid artery
Gives the transverse
facial artery
Supplies the temporal
region and anterior
quadrant of the scalp.

15. Maxillary Artery
Terminal branch of the
external carotid artery
Divided into 3 parts by
the lateral pterygoid
muscle.
Pterygoid part:
Mandibular part
Pterygomaxillary part

16. Maxillary Artery

17. Origin
Rt. Side –brachiocephalic
trunk
Lt. Side –direct branch from
the arch of aorta
Course
Arches laterally in the root of
the neck in front of the apex
of the lung
Ends at the outer border of
the first rib.

18. Divided by the scalenus
anterior
First part
Vertebral artery
Internal thoracic artery
Thyrocervicaltrunk
Second part
Costocervicaltrunk
Third part
Dorsal scapular artery.

20. Internal Jugular
vein.
External Jugular
vein.
Retromandibular
vein.
Facial vein

21. Continuation of the
sigmoid sinus
Descends along with the
internal carotid , common
carotid artery and the
vagus nerve
Terminates by joining the
subclavian vein

24. Formation: Union of posterior division of the
retromandibular vein and posterior auricular vein
Descends along the sternocleidomastoid muscle,
pierces the deep fascia and terminates into
subclavian vein
