Human Sacrum and Coccyx
Human Sacrum and Coccyx (Product Code: SLE/A/62) is a life-size, one-part model of the lowest section of the vertebral column: the wedge-shaped sacrum and the small tailbone below it. Anatomy, physiotherapy and nursing students use it to learn the landmarks of this region without handling a full skeleton, and it is a convenient desk piece when a complete human skeleton model is shared by a large class. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Typical Use
Osteology practicals usually ask students to identify the sacral promontory, the sacral foramina through which nerves pass, the auricular surfaces that meet the hip bones and the joint between sacrum and coccyx. A single-piece, life-size model lets each student turn the bone in the hand, compare the anterior and posterior surfaces and sketch them, then return it for the next group. At 0.2 kg it is light enough for repeated handling during a long practical.
Physiotherapy and sports-science tutors use the same model to explain low back and tailbone pain, the sacroiliac joint and the attachment points of pelvic muscles. It also works as an item of school biology lab equipment when senior students study the regions of the spine, because it shows clearly how several vertebrae fuse into one bone. Store it in a closed cupboard to keep it free of dust.
Manufacturer
The sacrum and coccyx model is part of the anatomy range made by Jain Scientific Equipments Private Limited, a company in Ambala, Haryana that sells its products under the ScienceLab brand. You can read how the company works on the profile page.
