After completing chapter 35, you will be able to: Describe the general functions of hormones and the endocrine system; identify the hormones released by the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and other hormone-producing organs, and give the functions of each; explain the effect of stressors on the body; describe the causes, signs and symptoms, and treatments of various endocrine disorders. | 35 Special Senses Learning Outcomes (cont.) Describe the anatomy of the nose and the function of each part. Describe the anatomy of the tongue and the function of each part. Describe the anatomy of the eye and the function of each part, including the accessory structures and their functions. Learning Outcomes (cont.) Explain the visual pathway through the eye and to the brain for interpretation. Describe the causes, signs and symptoms, and treatments of various disorders of the eyes. Describe the anatomy of the ear and the function of each part, and the role of the ear in maintaining equilibrium. Learning Outcomes (cont.)

Introduction Special senses – receptors in the head Nose Tongue Eyes Ears Touch is a generalized sense Stimulus nervous system brain response The special senses are smell, taste, vision, hearing, and equilibrium. These are special senses because their sensory receptors are located within relatively large sensory organs in the head. Touch is not considered a special sense but a generalized one. No matter how a stimulus starts, it is sent, via the nervous system, to the brain for interpretation and then reaction, if necessary. The Nose and the Sense of Smell Olfactory receptors Chemoreceptors – respond to changes in chemical concentrations Chemicals must be dissolved in mucus Located in the olfactory organ Learning Outcome: Describe the anatomy of the nose and the function of each part. Chemicals that activate smell receptors must be dissolved in the mucus of the nose. Smell receptors are located in the olfactory organ, found in the upper part of the nasal cavity. Chemicals must diffuse all the way up the nasal cavity in order to activate smell receptors. The Nose and the Sense of Smell (cont.) The .
