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.
 Lingual artery
 Facial 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
Thyrocervical trunk
 Second part
Costocervical trunk
 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
