Deluxe Dual-Sex Human Muscle Torso Model, 31-part

A top-of-the-range anatomy torso that shows both the superficial and deep muscles; the two main muscles — the deltoid and gluteus maximus — can be removed for closer study. The model also lets you examine the vertebrae, spinal cord, spinal nerves and vertebral arteries, exchange the male and female genital inserts, and explore the internal structures of the brain. Removable parts include a 6-part head, the chest and abdominal wall with muscles, the 7th thoracic vertebra, the female mammary gland, the gluteus maximus and deltoid, two lungs, a 2-part heart, a 2-part stomach, the liver with gall bladder, a 4-part intestinal tract, the front half of a kidney, a 3-part female genital insert with fetus and a 4-part male genital insert. Every organ is hand-painted, making the position of the human organs easy to learn.
