Use the function with the points (1.5, 3), (9, 10.5), Photoreceptors in the rods and cones in the retina respond to light. Finally, vision involves the activation of photoreceptors. When strong enough to reach threshold they can directly trigger an action potential along the axon of the sensory neuron. Merkels disks are found in the upper layers of skin near the base of the epidermis, both in skin that has hair and on glabrous skin; that is, the hairless skin found on the palms and fingers, the soles of the feet, and the lips of humans and other primates.

A third classification of receptors is by how the receptor transduces stimuli into membrane potential changes. An individual sensory modality represents the sensation of a specific type of stimulus. Another physical stimulus that has its own type of receptor is temperature, which is sensed through a thermoreceptor that is either sensitive to temperatures above (heat) or below (cold) normal body temperature.

A fifth type of mechanoreceptor, Krause end bulbs, are found only in specialized regions. This information is detected by sensory receptors in our muscles, ligaments, and joints, and then processed through the central nervous system. Sensations can also be protective to the body, by registering environmental cold or warm, and painful needle prick, for example. Through which cranial nerves does gustatory information travel? Trans-retinal disassociates from opsin and opsin becomes activated They can also be classified functionally on the basis of the transduction of stimuli, or how the mechanical stimulus, light, or chemical changed the cell membrane potential. 4.

Determine the angle that the transmission axis of the polarizing sheet makes with the horizontal. Merkel's discs detect sustained touch and pressure. They may be massed together to form a sense organ, such as the eye or ear, or they may be scattered, as are those of the skin and viscera. 2) Photoreceptors .

What chamber is between the iris and cornea? a. medial geniculate nucleus. 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. Humans can perceive various types of sensations, and with this information, our motor movement is determined. The general senses can be divided into somatosensation, which is commonly considered touch, but includes tactile, pressure, vibration, temperature, and pain perception. Krause end bulbs detect cold. 6. perilymph of scala tympani Muscle spindles are stretch receptors that detect the amount of stretch, or lengthening of muscles. Somatosensory Receptors | Biology for Majors II - Lumen Learning Mechanoreceptors in the skin are described as encapsulated (that is, surrounded by a capsule) or unencapsulated (a group that includes free nerve endings). In this demonstration, two sharp points, such as two thumbtacks, are brought into contact with the subjects skin (though not hard enough to cause pain or break the skin). Describing sensory function with the term sensation or perception is a deliberate distinction. the triangle, given the coordinates of its vertices. d. Cone a. basilar membrane. Nociceptors (pain receptors)- These receptors identify any extreme thermal or mechanical stimuli, which can be damaging. They are a cutaneous receptor found in the dermis or epidermis. They respond to fine touch and pressure, but they also respond to low-frequency vibration or flutter. These modalities include pressure, vibration, light touch, tickle, itch, temperature, pain, proprioception, and kinesthesia. 1. Optic nerve The cells that interpret information about the environment can be either (1) a neuron that has a free nerve ending(dendrites) embedded in tissue that would receive a sensation; (2) a neuron that has anencapsulated ending in which the dendrites are encapsulated in connective tissue that enhances their sensitivity; or (3) a specialized receptor cell, which has distinct structural components that interpret a specific type of stimulus (Figure 13.1.1). * saccharine, EXs associated w/ what taste sensation? David N. Shier, Jackie L. Butler, Ricki Lewis. The Lymphatic and Immune System, Chapter 26. Which auditory ossicle contacts the oval window? In skeletal muscle tissue, these stretch receptors are called muscle spindles. Such stretch receptors can also prevent over-contraction of a muscle. For example, the general sense of touch, which is known as somatosensation, can be separated into light pressure, deep pressure, vibration, itch, pain, temperature, or hair movement. The central integration may then lead to a motor response. The dynamics of capsaicin binding with this transmembrane ion channel is unusual in that the molecule remains bound for a long time. a.
