detect pressure, vibration. Optic disc We will discuss the special senses, which include smell, taste, vision, hearing and the vestibular system, in chapter 15. A special sense (discussed in Chapter 15)is one that has a specific organ devoted to it, namely the eye, inner ear, tongue, or nose. Sensory receptors are classified into five categories: mechanoreceptors, thermoreceptors, proprioceptors, pain receptors, and chemoreceptors. Begins in the oval window Electrical sensors and stimulators can help quadriplegic victims flex their limbs. The __________, the black hole in the eye, is surrounded by the colorful _________. The receptive fields of Merkels disks are small with well-defined borders. a. gets louder. Somatosensation is also known as tactile sense, or more familiarly, as the sense of touch. a. Lacrimal gland e. Sclera The Cardiovascular System: Blood Vessels and Circulation, Chapter 21. Three types of receptors detect touch: Meissner corpuscles, Merkel disks, and free nerve endings. Glutamate inhibits the bipolar cells that synapse with the rods. (a) To explain how to cure paralysis, (b) To persuade people to wear helmets, (c) To describe the effects of spinal injuries, (d) To describe different types of paralysis. What type of receptors detect deep pressure and vibration? Paraplegia, paralysis of both lower limbs, is caused by an injury lower on the spinal column. Various feature extraction methods have been proposed in the literature. An interoceptor is one that detects stimuli from internal organs and tissues, such as the receptors that sense the increase in blood pressure in the aorta or carotid sinus. Merkels disks are abundant on the fingertips and lips. { "36.01:_Sensory_Processes_-_Reception" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.

Q. They are found in the walls of the carotid artery and the aorta where they monitor blood pressure, and in the lungs where they detect the degree of lung expansion. Pressure, vibration, muscle stretch, and the movement of hair by an external stimulus, are all sensed by mechanoreceptors and perceived as touch or proprioception. -Pinna (auricle) Which of the following are functions of the inner ear? b. How does light affect rhodopsin? There are fewer Pacinian corpuscles and Ruffini endings in skin than there are Merkels disks and Meissners corpuscles. 7. ends with the round window, free nerve endings are terminal branches of. Deep pressure and vibration is transduced by lamellated (Pacinian) corpuscles, which are receptors with encapsulated endings found deep in the dermis, or subcutaneous tissue.
