(BQ) Part 2 book "Guyton and hall: Textbook of medical physiology" presents the following contents: General organization, the tactile and position senses; pain, headache, and thermal sensations; optics of vision; receptor and neural function of the retina,. Invite you to consult. | CHAPTER 48 Somatic Sensations I. General Organization the Tactile and Position Senses UNIT IX e somatic senses are the nervous mechanisms that collect sensory information from all over the body. ese senses are in contradistinction to the special senses which mean specifically vision hearing smell taste and equilibrium. CLASSIFICATION OF SOMATIC SENSES e somatic senses can be classified into three physiological types 1 the mechanoreceptive somatic senses which include both tactile and position sensations that are stimulated by mechanical displacement of some tissue of the body 2 the thermoreceptive senses which detect heat and cold and 3 the pain sense which is activated by factors that damage the tissues. is chapter deals with the mechanoreceptive tactile and position senses. In Chapter 49 the thermoreceptive and pain senses are discussed. e tactile senses include touch pressure vibration and tickle senses and the position senses include static position and rate of movement senses. Other Classifications of Somatic Sensations. Somatic sensations are also often grouped together in other classes as follows Exteroreceptive sensations are those from the surface of the body. Proprioceptive sensations are those relating to the physical state of the body including position sensations tendon and muscle sensations pressure sensations from the bottom of the feet and even the sensation of equilibrium which is often considered a special sensation rather than a somatic sensation . Visceral sensations are those from the viscera of the body in using this term one usually refers specifically to sensations from the internal organs. Deep sensations are those that come from deep tissues such as from fasciae muscles and bone. ese sensations include mainly deep pressure pain and vibration. DETECTION AND TRANSMISSION OF TACTILE SENSATIONS Interrelations Among the Tactile Sensations of Touch Pressure and Vibration. Although touch pressure and vibration are frequently classified as .
