Facial muscles, neck triangles & cranial cavity
Product code: HP0203

Single Side Left or right side of a region / system / organ.
The facial muscles play key roles in communication, feeding and maintenance of eye health. Their correct function is critical for normal functioning and wellbeing. A knowledge of their functions and pattern of innervation is essential in clinical examination and diagnosis. This Silicone Plastinate reveals key facial muscles and their pattern of innervation by the facial nerve, and the relationship of the facial nerve with the parotid gland. The boundaries and most contents of the anterior triangle of the neck, and of the medial part of the posterior triangle (lateral region) of the neck, are shown in their anatomical position.
