Order these structures from superficial to deep. c. Perilymph The . c. Hyperopia Listing all the different sensory modalities, which can number as many as 17, involves separating the five major senses into more specific categories, or submodalities, of the larger sense. Free nerve endings are sensitive to painful stimuli, to hot and cold, and to light touch. They contain mechanically gated ion channels whose gates open or close in response to pressure, touch, stretching, and sound. There are four primary tactile mechanoreceptors in human skin: Merkels disks, Meissners corpuscles, Ruffini endings, and Pacinian corpuscle; two are located toward the surface of the skin and two are located deeper. a. bony and membranous labyrinths.

Middle: The sensory fibers connect to the spinal cord through the dorsal root, which is attached to the dorsal root ganglion. Summarize Rutherfords model of the atom, and explain how he developed this model based on the results of his famous gold-foil experiment. transparent & avascular Specific types of receptors called _____ detect stimuli in the internal organs. Buds SURVEY . Barorecptors detect pressure changes in an organ. a. complex in structure : -Choroid - DARK - They are unmyelinated c - Inferior colliculus The papillae that are fewest in number, but contain the most taste buds, are the _________ papillae. e. Detectable odors are actually combinations of a smaller number of primary odors. They respond to fine touch and pressure, but they also respond to low-frequency vibration or flutter. There are four primary tactile mechanoreceptors in human skin: Merkels disks, Meissners corpuscles, Ruffini endings, and Pacinian corpuscle; two are located toward the surface of the skin and two are located deeper. A third classification of receptors is by how the receptor transduces stimuli into membrane potential changes. Tags: Question 22 .

What structure is attached to the oval window and transfers vibration of the tympanic membrane to the inner ear? 5. Thus, they also contribute to proprioception and kinesthesia. It is not surprising, then, that humans detect cold stimuli before they detect warm stimuli. Light touch is transduced by the encapsulated endings known as tactile (Meissners) corpuscles. c. Axons of ganglion cells from the retina of the right eye We will discuss the special senses, which include smell, taste, vision, hearing and the vestibular system, in chapter 15. Merkel's discs detect sustained touch and pressure. 6 - Scala vestibuli These categories are based on the nature of stimuli each receptor class transduces. Accordingly, cell type-specific deletion of PAR2 in myeloid immune cells resulted in a curtailed skin inflammation and hapten-specific T cell response in CHS mice. During hearing, the last structure(s) to vibrate is/are the Mechanoreceptors - provides sensations of touch, pressure, vibration, proprioception, Order the layers of the eye from superficial to deep.
