    Cutaneous receptors are sensory receptors located in the dermis‚ which is a layer of the skin. These receptors are responsible for sensations of touch‚ pressure‚ heat‚ cold‚ and pain. They are classified asmechanoreceptors which are associated with pressure‚ thermoreceptors which are associated with temperature‚ and nociceptors which are associated with pain (Brodal). Functional Anatomy There are five mechanoreceptors‚ free nerve endings‚ Meissner’s corpuscles‚ Pacinian Corpuscles‚ Merkel’s

    Increasing the stimulus amplitude will increase the contraction force. Due to two conditions being satisfied: (1) the strength of the contraction force is changed through varying the number of muscle cells utilized for the contraction and/or varying the frequency of the stimulus‚ and (2) there is a distribution of the stimulus amplitude necessary to cause an action potential in the muscle cells‚ increasing the stimulus amplitude makes it likely that a potentially larger number of muscle cells will

    concluded my discovery of space worm touch receptors is definite. Regardless of the type‚ sensory receptors are influenced by physical actions and various stimulus. My research and experiments show that space worm touch receptors are no different. Stimulus is a change discernible by the body (Sherwood 2004) or in my case‚ a space worm. Certain receptors like touch receptors respond to stimulus weakly or strongly when involved with a different stimulus (Sherwood 2004). This perfectly related to

    in the visceral region. An example is Irritable Bowel Syndrome (IBS) which has chronic pain as a symptom. A receptor that has been seen to be present and upregulated in this disease are Transient Receptor Potential (TRP) channels‚ and in particular‚ Transient Receptor Potential Vanilloid type 1 (TRPV1) and Transient Receptor Potential Ankyrin Type 1 (TRPA1)(15‚18). In this review‚ TRPV1 and other channels‚ such as TRPA1 induced pain are looked at. As possible drug targets‚ there have been studies

    1. What is modality? Modality is concerned with expressing opinions and attitudes. Modality in general is defined similarly in many reference books. For example Quirk‚ Greenbaum‚ Leech and Svartvik (1985) claim‚ that “at its most general‚ modality may be defined as the manner in which the meaning of a clause is qualified so as to reflect the speaker’s judgment of the likelihood of the proposition it expresses being true” (p. 219). However‚ the authors deal with the term modality mainly in connection

    How do skin receptors’ distribution change one’s reaction to pain in different areas of your body? Aim: Our senses are responsible for receiving information in the outside environment and sending it to our central nervous system‚ where this information is then interpreted. Organs such as the skin‚ known as sense organs‚ have specific neurons named receptorswhich are each responsible for responding to specific types of stimulus. The receptors responsible for identifying our sense of touch are distributed
