anatomical head model 3d

Detailed anatomical human head model for educational purposes, showing layered structure with removable parts. Include: outer facial muscles (masseter, temporalis, orbicularis oculi, zygomaticus, frontalis) with realistic muscle fiber texture, eyeballs with iris and sclera texture, brain with gyri and sulci surface detail with pink-gray texture, skull/cranium with bone texture visible underneath, parotid and submandibular glands, major nerves (facial nerve branches, trigeminal nerve). Each anatomical layer should be a separate mesh/part. Muscle tissue texture (red-pink striated fibers), bone texture (off-white porous surface), brain texture (pink-gray folded cortex), eye texture (realistic iris pattern). Medical illustration style, highly detailed, educational anatomical model, cross-section ready, no skin layer on one side to reveal underlying structures.
