Sensory receptors respond to: light touch: tactile (Meissner) corpuscles, in dermal papil- lae. 3) Lacrimal sac Cis-retinal and opsin re-form rhodopsin. Asama, Japan, is an active volcano. Below this, the much thicker dermis contains blood vessels, sweat glands, hair follicles, lymph vessels, and lipid-secreting sebaceous glands (Figure1).

K+, What neurotransmitter is released from depolarized hair cells to stimulate fibers of the vestibulocochlear nerve? In other words, they are detecting _________ -Sclera 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. Which of these is most vulnerable to irreversible damage caused by a very loud noise? d. tympanic membrane. - Exposure to acid on the skin They are rapidly- adapting, fluid-filled, encapsulated neurons with small, well-defined borders which are responsive to fine details. Note that these warmth detectors are situated deeper in the skin than are the cold detectors. E-Book Overview INTRODUCTION TO HEALTH CARE, 3E provides learners with an easy-to-read foundation in the profession of health care. That makes them finely sensitive to edges and they come into use in tasks such as typing on a keyboard. (Note that the special senses are all primarily part of the somatic nervous system in that they are consciously perceived through cerebral processes, though some special senses contribute to autonomic function). Receptors are the structures (and sometimes whole cells) that detect sensations. b) Heat. Middle ear 3. b. Visceral pain can be so great that it causes somatic pain. The lacrimal gland is made of two parts, the palpebral part and the __________ part. The nociceptive receptorsthose that detect painare located near the surface. In this chapter we will discuss the general senses which include pain, temperature, touch, pressure, vibration and proprioception. The sphincter pupillae is controlled by the __________ division of the nervous system. For example, the sensation of pain or heat associated with spicy foods involves capsaicin, the active molecule in hot peppers. For example, a molecule in food can serve as a ligand for taste receptors. How does light affect rhodopsin?
What is the receptor of deep pressure? - AnswersAll Which layer of the eye contains the blood and lymph vessels? A detached retina is caused by a separation between which two layers? 3. What type of receptor monitors changes in position? d. gets lower. 4.
Deep pressure and vibration are detected by which of the following? A Bulbous corpuscles are also present in joint capsules, where they measure stretch in the components of the skeletal system within the joint. Which layer of the retina provides vitamin A for the photoreceptor cells? 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). c. hair cells of spiral organ. Perception is dependent on sensation, but not all sensations are perceived. All of the following are . The receptive fields of Merkels disks are small with well-defined borders. -Iris e. stapes. b. Pigmented layer of retina d. Fibers of the cochlear nerve - Pharyngotympanic tube Drag and drop the labels into the appropriate location on the figure. Golgi tendon organs similarly transduce the stretch levels of tendons. Ask anyone what the senses are, and they are likely to list the five major sensestaste, smell, touch, hearing, and sight. Myopia a. medial geniculate nucleus. deep pressure and vibration: lamellar (Pacinian) corpus- cles, in reticular layer. 2. Both primary somatosensory cortex and secondary cortical areas are responsible for processing the complex picture of stimuli transmitted from the interplay of mechanoreceptors. interoceptors Place the three regions of the ear in order from lateral to medial: - external ear - inner ear - middle ear 1. This allows sodium ions to flow into the cell, creating a receptor potential. The main sensory modalities can be described on the basis of how each stimulus is transduced and perceived. Order the auditory ossicles from lateral to medial. The distribution of touch receptors in human skin is not consistent over the body. 3. perilymph of scala vestibule Merkels disks, which are unencapsulated, respond to light touch. There are fewer Pacinian corpuscles and Ruffini endings in skin than there are Merkels disks and Meissners corpuscles. Sensory receptors in the utricle detect the position of the: __________ occurs when impulses from an organ are perceived as originating from the skin. Graded potentials in free and encapsulated nerve endings are called generator potentials. Taste buds are made of gustatory cells, supporting cells, and __________ cells. c. Norepinephrine The Cardiovascular System: Blood Vessels and Circulation, Chapter 21. An exteroceptor is a receptor that is located near a stimulus in the external environment, such as the somatosensory receptors that are located in the skin. What is the magnitude of the block's acceleration vector? b. inferior colliculus. To view close objects, the ciliary muscle will _____, the suspensory ligament will _____, and the lens will become more _______. Q. Rods continuously release the neurotransmitter glutamate. Lies deep to dermis. a - Thalamus The cells in the retina that respond to light stimuli are an example of a specialized receptor cell, a photoreceptor. c.primary auditory cortex. Neurons are not physically connected, but communicate via neurotransmitters secreted into synapses or gaps between communicating neurons. That makes them very sensitive to edges; they come into use in tasks such as typing on a keyboard. Both the upper and lower layers of the skin hold rapidly and slowly adapting receptors. Farsightedness disorder in which the cornea and lens system is optically too weak or the eyeball is too short. 7. basilar membrane 3) Horizontal cells a. Semicircular canal b. * caffeine d. Reduced lens flexibility, Photoreceptors in the retina of the eye detect changes in light intensity and wavelength. Ruffini endings are slow adapting, encapsulated receptors that respond to skin stretch and are present in both the glabrous and hairy skin. Why is visceral pain sometimes localized incorrectly? In 2009, an eruption threw solid volcanic rocks that landed 1km1 \mathrm{~km}1km horizontally from the crater. c. primary auditory cortex. the general sense of touch, which is known as somatosensation, can be separated into light pressure, deep pressure, vibration, itch, pain, temperature, or hair . Overlapping between Wound Healing Occurring in Tumor Growth and in Central Nervous System Neurodegenerative Diseases.
Types of Sensory Receptors and the Sensory Stimuli They Detect __________ of the eye is receded into the orbit.

What structure is the dividing line between the anterior and posterior chambers? Which of the following muscles are located within the middle ear? The points could then be moved closer and re-tested until the subject reports feeling only one point, and the size of the receptive field of a single receptor could be estimated from that distance. Note that these warmth detectors are situated deeper in the skin than are the cold detectors. - LIGHT 6. Figure3.
