Transcript of Head and neck blood vessels 2
Artery
Veins
Two main arteries:
External Carotid Artery
Subclavian Artery
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
Branches:
Ascending Pharyngeal artery.
Superior thyroid artery.
Lingual artery
Facial artery
Posterior auricular artery
Occipital artery
Superficial temporal artery
Maxillary artery
Ascending
pharyngeal artery
Occipital artery
Posterior auricular
artery
Superior thyroid artery
Lingual artery
Facial artery
Ascending
pharyngeal artery
Ascends the wall of the pharynx
Supplies pharynx and palatine tonsil
Superior thyroid
artery
Passes along with the external laryngeal nerve
Supplies thyroid gland
Gives superior laryngeal artery
Lingual artery
Passes towards
the tongue deep to
the hyoglossus
muscle
Divided into three
parts
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
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
Occipital artery
Passes posteriorly along the
lower border of the posterior
belly of the digastric muscle
Supplies posterior quadrant
of the scalp
Occipital artery
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.
Maxillary Artery
Terminal branch of the external carotid artery
Divided into 3 parts by the lateral pterygoid muscle. Pterygoid part:
Mandibular part
Pterygomaxillary part
Maxillary Artery
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.
Divided by the scalenus
anterior
First part
Vertebral artery
Internal thoracic artery
Thyrocervical trunk
Second part
Costocervical trunk
Third part
Dorsal scapular artery.
Internal Jugular
vein.
External Jugular
vein.
Retromandibular
vein.
Facial vein
Continuation of the sigmoid sinus
Descends along with the internal carotid , common carotid artery and the vagus nerve
Terminates by joining the subclavian vein
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
