A comprehensive presentation of the construction, biology and function of the human body in three volumes. Volume III comprises the Eye and Vision, Ear and Auditory Mechanism, Sense of Equilibrium, Sensory Perception: Smell, Taste, Touch, Perception of Temperature and Movement, Hormones and Hormone Systems. These atlases of human biology and life science are of great value for teaching in schools, colleges and universities, in the training of nurses, medical technicians and for the students of physiotherapy and physical education.

CONTENTS:

• 27 Overhead-Transparencies, size 22 x 28 cm, comprising 75 colour pictures, mostly with several component figures (anatomical pictures, photomicro- and macrographs, nature photographs, human photographs, electron micrographs, X-ray photographs, drawings, diagrams, tables, scenes, test data and results). The colour pictures were prepared by university illustrators specialising in this field.
• Sketch and work-sheets with semi-diagrammatic designs and texts. Teacher may take photocopies from the sheets and use for classroom work and tests.
• Brochure with depictured explanatory comments for the teacher. All in strong plastic file with ring-mechanism.

Eye and Vision - Range of visible light in the electromagnetic spectrum - The human eye. Eyeball, eye muscles, eyelid, sagittal section - Human retina, t.s. detail view. Rods, cones, bipolar cells, ganglion cells, photomicrograph - Human retina. Chief synaptic connections, diagram - Retina, t.s. for detail of rods and cones - Orbital muscles of the eyeball - Optic pathways, optic chiasm, diagram - Retina seen through the ophthalmoscope. Central fovea, optic disc - Formation of an image in a normal eye - The eye as a camera - Accommodation for distant and near vision - Pupillary light reflex - Image produced by "normal" and astigmatic glasses - Eye with pathological turbidity of the lens (cataract) - Defects of vision: short-sighted and far-sighted eye - Image produced by an astigmatic cornea - Tests for colour-blindness. Red-green deficiency and blue weakness - Optical illusions by ambiguous information - Optical illusions caused by the influence of the surrounding areas - Optical illusions caused by non-conformity of rational interpretation and optical perception - Trichromatic triangle. Different combinations of three primary colours give all other colours - Spectral sensitivity of rods and cones (dominator system), three pigment colour vision (modulator system).

Ear and Auditory Mechanism, Sense of Equilibrium - The formation of sound waves. Areas of rarefaction and areas of compression caused by a tuning fork. - Anatomy of the human ear. Ear concha, external auditory canal, middle ear, internal ear - Movement of the eardrum, auditory ossicles, oval window and round window - Position of epithelia of the internal ear - Organ of Corti, diagram - Movement of Reissner’s membrane and basilar membrane. Stimulation of the hair cells by the hairs in the tectorial membrane - Broadening of the basilar membrane from the base of the cochlea to the helicotrema - Formation of damped waves in the membraneous labyrinth - Displacement of the membraneous labyrinth by the waves generated by sound vibrations - Amplitude pattern of vibration of the membraneous labyrinth for high and low frequencies - Detection of sound direction by the time difference between the entry of sound into the ears - Diagram of main auditory pathways. Acoustic centres in the brain - Function of the vestibular system.

Sensory Perception: Smell, Taste, Touch, Perception of Temperature and Movement - Section through nasal cavity and pharyngeal cavity - Location of the olfactory mucous membrane and respiratory pathway - Nasal conchae of human and deer. Microsmates, macrosmates - Olfactory and respiratory mucous membrane t.s. - Detail view of olfactory epithelium with sensory cilia - Tongue of rabbit, t.s. of papilla foliata with taste buds - Human skin from palm, v.s. showing cornified epidermis, germinative zone, sweat glands, diagram - Human scalp, vertical section showing l.s. of hair follicles, sebaceous glands, epidermis - Human skin with cutaneous receptors of touch, pressure and thermal sensation - Tactile hair, median l.s. and t.s. - Ruffini’s warmth receptor - Krause’s corpuscle, cold receptor - Meissner’s corpuscle from human finger - Back of human hand marked with warmth and cold spots - Sensitivity differences caused by touch-stimulation: excitation nearby or far away, weak or strong - Proprioceptors: muscle spindle and Golgi tendon apparatus. Conscious awareness of the position and movements of the joints.
