If the statement is false, change the underlined word or words to make the statement true. receptors in the eye respond to a different type of input than receptors in the skin. Pain is primarily a chemical and sometimes mechanical sense that interprets the presence of chemicals from tissue damage, or intense mechanical stimuli, through a nociceptor. (Consider that the deep pressure that reaches those deeper receptors would not need to be finely localized.) These injuries may result from sports or recreational activities, motor vehicle crashes, falls, physical assaults, and gunshot wounds.

Modality refers to the way that information is encoded into a perception. interoceptors Place the three regions of the ear in order from lateral to medial: - external ear - inner ear - middle ear 1. a) Vibration. Which layer of the eye contains the blood and lymph vessels? Thus, they also contribute to proprioception and kinesthesia. An individual sensory modality represents the sensation of a specific type of stimulus. This is because what type of receptors detect deep pressure and vibration? It is not surprising, then, that humans detect cold stimuli before they detect warm stimuli. f. Choroid Action potentials are transmitted out of the optic nerve. Solve a concrete slab is reinforced by 16mm16 -\mathrm{mm}16mm-diameter steel rods placed on 180mm180-\mathrm{mm}180mm centers as shown. Recall that the epidermis is the outermost layer of skin in mammals. Finally, a proprioceptor is a receptor located near a moving part of the body, such as a muscle or joint capsule, that interprets the positions of the tissues as they move. They are found in the bone periosteum, joint capsules, pancreas and other viscera, breast, and genitals. That makes them finely sensitive to edges and they come into use in tasks such as typing on a keyboard. Mechanoreceptors in the skin, muscles, or the walls of blood vessels are examples of this type. Three ways to classify receptors 1. type of stimulus 2. body location 3. structural complexity Mechanoreceptors respond to touch, pressure, vibration, and stretch Theremoreceptors sensitive to changes in temperature Photoreceptors respond to light energy (retina) Chemoreceptors respond to chemicals (e.g., smell, taste, changes in blood chemistry) __________ pain is a sensation associated with a body part that has been removed. Action potentials triggered by receptor cells, however, are indirect. c. Hyperopia Meissners corpuscles are rapidly-adapting, encapsulated neurons that responds to low-frequency vibrations and fine touch; they are located in the glabrous skin on fingertips and eyelids. The cranial nerves are connected to the same side of the brain from which the sensory information originates. Sensations can also be protective to the body, by registering environmental cold or warm, and painful needle prick, for example. Thermoreceptors are sensitive to temperature changes, and photoreceptors are sensitive to light energy. Mechanoreceptors - provides sensations of touch, pressure, vibration, proprioception, The sensory fibers connect to the spinal cord through the dorsal root, which is attached to the dorsal root ganglion. 6. perilymph of scala tympani Graded potentials in receptor cells are called receptor potentials. They will respond to the stimulus as long as it persists, and produce a continuous frequency of action potentials. 4 - The vestibular membrane begins to vibrate. (credit: modification of work by Wbensmith/Wikimedia Commons; scale-bar data from Matt Russell). 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. 2) Vascular tunic Stretch receptors monitor the stretching of tendons, muscles, and the components of joints.

Temperature receptors are stimulated when local temperatures differ from body temperature. Stretching of the skin is transduced by stretch receptors known as bulbous corpuscles. Unconscious proprioceptive signals run from the spinal cord to the cerebellum, the brain region that coordinates muscle contraction, rather than to the thalamus, like most other sensory information. As the number of cycles per second increases, the sound we perceive detect pressure, vibration.
