External carotid artery territory
Product code: HP0201
-
Single Side Left or right side of a region / system / organ.
The external carotid artery supplies blood to the majority of viscerocranium and associated soft tissue structures, and to the scalp, dura, bones of the neurocranium, thyroid gland, pharynx and parts of the larynx. This Silicone Plastinate reveals the position, course, and relations of the branches of the external carotid artery in the parapharyngeal space and infratemporal fossa. The median sagittal section enables exploration of the nasal and oral cavities, pharynx and larynx. Removal of the calvaria and brain reveals the cranial fossae, and the points of cranial nerve exit from and arterial entry into the cranial cavity.

- Branches and territory of the external carotid artery.
- Medial view of a median sagittal section of the head and neck.
- Superior part of calvaria and associated soft tissue removed to provide clear views of the base of skull.
- Most veins removed to provide clear views of underlying structures.
Head
- Cranial branches of the external carotid artery.
- Zygomatic arch and the ramus and angle of mandible removed to reveal the infratemporal fossa, and the maxillary artery and its branches.
- Brain removed to reveal the dura-lined cranial cavity and base of skull, and the sites of cranial nerve and blood vessel exit from/entry into the cranial cavity.

- Arterial supply to the face and part of the scalp.
Neck
- Cervical branches of the external carotid artery.
- Partial or complete removal of sternocleidomastoid, various hypaxial and epaxial muscles of the back, and most veins to provide clear views of the arteries, nerves, and deep muscles of the neck.

- Spinal cord in the vertebral canal, with its meningeal coverings and the epidural space.
- Suboccipital region and its contents, including regional muscles, triangles, and nerves.
- Apical region of thorax with parietal pleura removed to reveal the superior thoracic aperture and associated structures, including the root of the T1 spinal nerve and the thoracic sympathetic trunk and cervicothoracic (stellate) ganglia.
- Structure of the superior part of the thoracic wall, including the intercostal spaces, sternoclavicular joint, and medial clavicle.
