Mechanoreceptors in the skin, muscles, or the walls of blood vessels are examples of this type. *Stapes Below this, the much thicker dermis contains blood vessels, sweat glands, hair follicles, lymph vessels, and lipid-secreting sebaceous glands (Figure1). The most obvious omission from this list is balance. e. Lateral geniculate nucleus - It is a benign tumor Merkel's disk are slow-adapting, unencapsulated nerve endings that respond to light touch; they are present in the upper layers of skin that has hair or is glabrous. Mechanoreceptors respond to mechanical stimuli and are the basis for most aspects of somatosensation, as well as being the basis of audition and equilibrium in the inner ear. Such low frequency vibrations are sensed by mechanoreceptors called Merkel cells, also known as type I cutaneous mechanoreceptors. Deep pressure and vibration is transduced by lamellated (Pacinian) corpuscles, which are receptors with encapsulated endings found deep in the dermis, or subcutaneous tissue. 7. ends with the round window, free nerve endings are terminal branches of.

Lamellated corpuscles b. The brain can determine the static position of the head due to sensors in the - Neural layer of the retina b. Ampullae - Utricle. When strong enough to reach threshold they can directly trigger an action potential along the axon of the sensory neuron. 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). The cranial nerves can be strictly sensory fibers, such as the olfactory, optic, and vestibulocochlear nerves, or mixed sensory and motor nerves, such as the trigeminal, facial, glossopharyngeal, and vagus nerves. 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) c. Axons of ganglion cells from the retina of the right eye Krause end bulbs detect cold. The cells in the retina that respond to light stimuli are an example of a specialized receptor cell, a photoreceptor. The test uses radio frequency waves and a strong magnetic field to create the images of your veins. Several distinct receptor types form the somatosensory system including thermoreceptors (heat), nociceptors (pain), and mechanoreceptors (pressure). What causes Trachoma, a type of conjunctivitis? a.

Figure4. Some other organisms have receptors that humans lack, such as the heat sensors of snakes, the ultraviolet light sensors of bees, or magnetic receptors in migratory birds. detect deep pressure, vibration, position. In 2009, an eruption threw solid volcanic rocks that landed 1km1 \mathrm{~km}1km horizontally from the crater. They are slow-adapting, unencapsulated nerve endings, which respond to light touch. They are a cutaneous receptor found in the dermis or epidermis. It dissociates rhodopsin and changes 11-cis-retinal to all-trans-retinal. 7. basilar membrane, What ion is responsible for depolarization of hair cells of the spiral organ? has no output arguments. a. Na+ 4. vestibular membrane a.The brain gives preference to exteroreceptors. If strong enough, the graded potential causes the sensory neuron to produce an action potential that is relayed into the central nervous system (CNS), where it is integrated with other sensory informationand sometimes higher cognitive functionsto become a conscious perception of that stimulus. Order the regions of the ear from lateral to medial. What are the sense receptors for each of the 5 senses? Which structure is filled with pigment from melanocytes?

Somatosensation is considered a general sense, as opposed to the submodalities discussed in this section. what is a wild type receptor? Deep pressure and vibration is transduced by lamellated (Pacinian) corpuscles, which are receptors with encapsulated endings found deep in the dermis, or subcutaneous tissue. e. Detectable odors are actually combinations of a smaller number of primary odors. -Cochlea Pacini corpuscles are found in both glabrous and hairy skin. muscle systems has important sensory structures called stretch receptors, which monitor the state of the muscle and return the information to the central nervous system. d. Lacrimal punctum Deeper in the epidermis, near the base, are Ruffini endings, which are also known as bulbous corpuscles. Any deformation in the corpuscle causes action potentials to be generated by opening pressure-sensitive sodium ion channels in the axon membrane. a. Ossicles (Gauge pressure is the difference between the actual pressure and atmospheric pressure.). Follicles are also wrapped in a plexus of nerve endings known as the hair follicle plexus. Meissner corpuscles are dendrites encapsulated in connective tissue and respond to changes in texture and slow vibrations. Journals. __________ of the eye is receded into the orbit. In addition to these two types of deeper receptors, there are also rapidly adapting hair receptors, which are found on nerve endings that wrap around the base of hair follicles. Receptor cells can be classified into types on the basis of three different criteria: cell type, position, and function. Activated rhodopsin inhibits the production of glutamate by rods. These are slow-adapting, encapsulated mechanoreceptors that detect skin stretch and deformations within joints, so they provide valuable feedback for gripping objects and controlling finger position and movement. Gustatory cells have a __________ lifespan. photoreceptor: A specialized neuron able to detect and react to light. Neurons are not physically connected, but communicate via neurotransmitters secreted into synapses or gaps between communicating neurons. a. Incus -Aqueous humor, Indicate whether each item is composed of transparent (clear) material through which light passes, or if the item is an opaque structure not involved in the transmission of light. Pacinian corpuscles detect transient pressure and high-frequency vibration. Asama, Japan, is an active volcano. b. Sensory receptors are classified into five categories: mechanoreceptors, thermoreceptors, proprioceptors, pain receptors, and chemoreceptors. Each year in the United States, 10,000 new cases of spinal cord injury are reported. 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. Pacinian corpuscles, such as these visualized using bright field light microscopy, detect pressure (touch) and high-frequency vibration. The sensory fibers connect to the spinal cord through the dorsal root, which is attached to the dorsal root ganglion. The structural classifications are either based on the anatomy of the cell that is interacting with the stimulus (free nerve endings, encapsulated endings, or specialized receptor cell), or where the cell is located relative to the stimulus (interoceptor, exteroceptor, proprioceptor). Perilymph is located between the -Tensor tympani muscle For this reason, capsaicin can be used as a topical analgesic, such as in products like Icy Hot. What lobe of the brain processes auditory information? These modalities include pressure, vibration, light touch, tickle, itch, temperature, pain, proprioception, and kinesthesia. Tags: Question 22 . b. sensations. d. Fovea centralis After turning on a bright light in a previously dark room, it is difficult to see for a brief time. Modality refers to the way that information is encoded into a perception.

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. Meissners corpuscles, (shown in Figure3) also known as tactile corpuscles, are found in the upper dermis, but they project into the epidermis.
