Our brain gets an enormous amount of information about the texture of objects that we encounter through our fingertips because the ridges that make up our fingerprints are full of these skin sensitive mechanoreceptors. Mechanoreceptors are found to be the most sensitive touch receptors because they are placed in non-hairy skin area such as the palms, lips, tongue, fingertips and the face. Thermoreceptors are as their name suggests receptors that perceive sensations
A simple task when looked at on a different level gives us an idea of how the body and mind works to produce an action and a result. For instance, there are perceptive processes within the vital steps during a jump shot. Shooting a basketball whilst may seem like a trivial task, requires hand-eye co-ordination as well as visual, depth and touch perception. This essay will focus specifically on one fluid motion; the moment the player bends his knees through to when the ball is released from his fingertips
Motion Sickness Ever felt carsick, airsick or seasick? Motion sickness is the most common medical problem associated with travel. As a child I was always told that "it was in my head," that if I wanted to, I could make it go away. I was made to believe that motion sickness was a psychological problem. To certain extend it is true that it is in my head, but it is not a psychological defect, but rather, a disorder that occurs when conflicting sensory information is sent to the brain. This mild
defined in the lab manual as the sense of touch. The four types of mechanoreceptors that were discussed in class were the Merkel complexes, Ruffini endings, Meissner’s corpuscle, and the Pacinian corpuscle (Lab Manual). The Merkel complexes were slow adapting mechanoreceptors whose primary function was to discriminate the texture, or pattern of an object (Lab Manual). The Ruffini endings were also slow adapting mechanoreceptors, but their primary function was to differentiate finger position and
Definition A sensory receptor is a structure that reacts to a physical stimulus in the environment, whether internal or external. It is a sensory nerve ending that receives information and conducts a process of generating nerve impulses to be transmitted to the brain for interpretation and perception. Sensory receptors vary in classifications but generally initiate the same process of registering stimuli and creating nerve signals. Classifications Stimulus modality is defined as an aspect of a stimulus
2003). Joint position sense and kinetic sense are essential for proper joint function in daily activities. Mechanoreceptors are peripheral afferents and transmit signals that the joint position and kinetic senses identify (Lephart & Fu, 1995). Mechanoreceptors are located in spindle endings and tendonn organs in muscles, or Ruffini spray endings in deeper tissue (Stillman, 2002). Mechanoreceptors can act at different speeds, and conscious proprioception can pl...
Electroreception of monotremes is partially comparable to that in fish. The bill of the platypus, Ornithorhynchus anatinus, and the beaks of the echidnas, Tachyglossus aculeatus and Zaglossus bruijni, all contain three types of receptors: push-rod mechanoreceptors, serous gland electroreceptors, and mucous gland electroreceptors. The information collected by these receptors is sent to the somatosensory cortex. The platypus, whose electroreceptive system is more complex than that of the echidna, uses electroreception
called the Somatosensory System. A system of which is responsible for all of the feelings we feel physically, how can it be simple? Well, it’s not. Four different typed of receptors make us this Somatosensory System. They are listed as follows: mechanoreceptors, pain receptors, proprioceptors, and ther... ... middle of paper ... ...ritis, and the list goes on. Treatment is rather simple, yet it has no promising effects. Doctors recommend the patient to ice the wrists, keep the wrist activity down
Touch Receptors are the nerves cells that tell your brain about tactile sensations. There are several types of touch receptors, but they can be divided into two groups. Mechanoreceptors that give the sensations of pushing, pulling or movement, and thermoreceptors that tell you about sensations of temperature. The mechanoreceptors contain the most types of touch receptors. Free nerve endings inform the brain about pain, and they are located over the entire body. Located in the deep layers of dermis
The Five Senses When humans were evolving a key to their development was The Five Main Senses that we knew today as Hearing, Sight, Smell, Taste and Touch. The loss of any of these could have affected the survival of our Ancestors, but in modern times, the partial to total loss of any of The Five Main Senses does not carry the same danger. However today, losing one of our main senses can be uncomfortable and isolating, but it does not mean that our useful lives are over. The loss of each
metaboreflex works as a significant blood pressure elevating response during the trainings and functions so it can redistribute blood flow and also help for blood volume. As a result, the mechanoreflex is a reflex triggered by stimulation of a mechanoreceptor. Exercising is a good source to prevent obesity and cardiovascular disease. The Scientist Ligia M. Antunes and her coworkers performed different methods for this experiment such as: studying the population, measures and procedures, musclemechanoreflex
In 1973, Dr. Kenso Kase created Kinesiology Tape (KT-Tape) in order to reduce physiology effects such as pain, joint misalignment, and to further support the range of motion in muscles (Kase et al., 1998). Since then the fields of physical and alternative therapy have been using it to complement their patient’s exercise programs. This form of treatment has been found promising for sport injuries and musculoskeletal disorders, but also as treatment for side effects of cancer (Smykla, 2013). In
environment (2011). One form of sensory is electroreception, which is the detection of electrical currents or fields in aquatic mammals and mechanoreceptors are specialized to respond to different types of mechanical stimuli, such as touch, taste, smell, etc. (2011). The platypus (Ornithorhynchus anatinus) exhibits electroreception with the help of mechanoreceptors to detect prey item while submerged in water. In general, electroreceptive fishes are categorized into non-electric fishes and electric fishes
Human Anatomy & Physiology. 10th ed. N.p.: Pearson Education, 2016. Pg. 279-314. Print. 3. Describe the stimuli and controls of digestive activity. Digestive activities within the GI tract are triggered by mechanical and chemical stimuli (mechanoreceptors and chemoreceptors that respond to stretch, changes in osmolarity and pH, as well as the presence of substrate and end products of digestion). External stimuli (sight, smell, taste, thought of food). Controls of the digestive activity are both
My favorite type of cell is the Merkel cell, also known as the “touch cell”. Merkel cells are found in the outer layer of the skin, or the epidermis. Named after Friedrich Merkel, the German anatomist discovered these cells in the late nineteenth century while studying rats, which have large quantities of Merkel cells in their paws (“What is a Merkel Cell?”). Not much is known for certain about these cells to this day, but one thing is for sure: they function as touch receptors by signaling sensations
"Oww! &%$%!" Pathways of Pain and Alternative Methods of Pain Relief Have you ever wondered why when you stub your toe on the chair in the living room, it helps tremendously to yell out an expletive or two and vigorously rub the area? I may not be able to discuss the basis for such language in this paper, but we will explore the analgesic response to rubbing that toe, in addition to the mechanism of pain and alternative treatments such as acupuncture and transcutaneous electrical nerve stimulation
In some cases, automatic top-down processing of stimuli even seems obligatory. J. R. Stroop (1935) first demonstrated the obligatory nature of reading. In the study, subjects were presented with a list of words of various colors: red, green, blue, brown, and purple. The words were presented in color so that each word was not printed in its representative color; that is, the word “red” could appear in blue ink, or the word “brown” in green ink. The subjects were then asked to relay the color of the
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system. The sensory system’s organs are the sense organs of the body. The purpose of the sensory system is to allow us to experience outside stimuli and identify alterations in the environment
Proprioception refers to the unconscious awareness and perception of joint and body movement, as well as the position of the body in space (Sherrington, 1906; as cited in Fisher et al., 1991:84). It is the “the sensory information caused by the contraction and stretching of muscles and by the bending, straightening, pulling and compression of the joints between bones” (Ayres, 2005:41). The muscles and joints constantly send information to the brain about the position of the body in space. However
is believed to cause chronic back pain (Weiner & Nordin, 2010). It occurs when there is an extrusion of disc material into the surrounding tissue (Weiner & Nordin, 2010). It is also suggested that abnormal stress of the ligaments, muscles and mechanoreceptors contribute to back pain (Weiner & Nordin, 2010). The main cause of chronic back pain has not been identified, but there are many suggested issues that are believed to contribute to chronic back pain. Symptomology: Simple musculoskeletal back
