Our most popular brain model reproduces the brain of a right-handed person, employing contrasting colors and hand-lettered captions to locate and identify motor and sensory functional centers. In addition to focusing on the intellectual role of the dominant left brain, and the creative role of the right, the model highlights the emotional, sexual, memory and learning functions of the limbic system.

Sensory regions and centers receptive to 20 specific body regions are distinguished, as are the motor centers controlling 19 body regions. More than 120 features, hand-numbered on the model, are identified in the corresponding key.

Overall dimensions: 8x8x10 inches (20x20x25cm). Nested on special display base which afford simultaneous observation of their superior, inferior and lateral aspects. Simply life them off their bases for disassembly and hands-on study.

Cast in nonbreakable vinyl plastic, our deluxe Human Brain model incorporates the arterial blood supply complete with termini of the internal carotids, basilar artery, and Circle of Willis. Cranial nerves and a dissectible brain stem are featured as well. The right hemisphere divides in two, while the left splits into four segments, including half of the brain stem and half of the cerebellum. Also detachable are the pituitary and the basilar artery.

Safe for pass-around - because all detachable components are secured with pins - the brain won?t come apart until pulled apart. Resting on its molded display base which permits simultaneous observation of its superior, inferior and lateral aspects, the brain simply lifts off its base for disassembly and hands-on study.

115 features, including the twelve cranial nerves, are numbered on the model and are identified in the accompany key. Overall dimensions: 6x5x7 inches (14x13x18cm).

Extra Value Feature: Supplied with this model is a set of reproducible copy masters for producing illustrated study/quiz sheets with multiple views of the brain, its ventricles, meninges and sinuses.

Portraying the base of the human head, this life-size nonbreakable replica features a detailed brain, complete with arterial blood vessels, including the basilar artery and Circle of Willis, cranial nerves, and dissectible brain stem.

The entire brain can be lifted from the cranial vault and separated in seven parts. The right cerebral hemisphere divides along its length following the border of the corpus callosum, while the left can be split to expose the posterior horn of the lateral ventricle and hippocampus. Dissections of the cranial floor expose the eyeball, its muscles, lacrimal gland, optic nerve, and the middle and inner ear. 107 hand numbered features are identified in the accompanying key.

This amazing working model of the human heart and circulatory system will bring your lecture to life! A complete schematic model of the human circulatory system with "blood" (colored water) that flows through transparent veins, arteries, capillaries and heart chambers. This model's special design portrays venous blood, a deep reddish purple and arterial blood, a bright red to give visual reinforcement to the oxygenation and deoxygenation of hemoglobin as it travels the body's vascular network. The functional heart and circulatory system are mounted on a baseboard with support legs and supplied with teacher's guide, red dye and syringe for refilling the system.

With this model the functions of the human eye can be taught very effectively. By moving the retina, the shape of the eye can be changed. The lens and ciliary body are made of silicone to allow the change of form and thickness of the lens. Pictures can be projected on the retina that allows you to demonstrate:

• Accommodation of the lens
• Near point of vision
• Myopia (near sightedness)
• Hypermetropia
• Presbyopia
• How to correct these problems with glasses

Comes with detailed instruction manual.

Demonstrates how the vertebrae of the human spinal column react when heavy objects are lifted correctly and incorrectly. The manikin will lift a weight from either of two position. If the correct posture is used, the spine is undistorted (no spaces between the vertebrae). The incorrect posture causes obvious visible strain to the simulated vertebrae. The rugged base features anatomical illustrations of the effect on the spine. Designed by a physical therapist.

Free booklet entitled "Safe Manual Handling" is included. Size: On a 5-1/2" x 9" base; 16-1/2" tall when standing.
