Triangles of the neck
Product code: HP0209
-
Single Side Left or right side of a region / system / organ.
For descriptive purposes and to aid clinical examination, the neck is divided into a series regions or triangles, each of which has a combination of muscular and/or osseous borders. Each triangle/region contains different collections of muscles, neurovasculature, lymphatics and organs, with structures distributed in layers and across different fascial planes (compartments/spaces). This Silicone Plastinate enables the boundaries and contents (some) of the neck triangles/regions to be explored, alongside their communication with the head, thorax, and axilla.

- Borders and contents (some) of the triangles/regions of the neck.
- Medial view of a median sagittal section of the neck.
- Sagittal section through the shoulder joint, revealing its relationship with the rotator cuff muscles, deltoid and coracoacromial arch.
- Most superficial veins removed to provide clear views of underlying structures.
- Internal jugular and subclavian veins retained.

- Posterior triangle (lateral region) of the neck and its sub-triangles (regions), and contents.
- Various hypaxial and epaxial muscles of the posterior neck and back of thorax (superior part).
- Suprahyoid and infrahyoid muscles.
- Inferior part of tongue and floor (inferior region) of mouth.
- Submandibular gland and its anatomical relations.
- Inferior part of parotid gland, and its relationship with the masseter and the mandible (superficial and deep parts).
