increased and modulated(8)‚ such as 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

What .is the role of acetylcholine in a skeletal muscle contraction? Skeletal muscle fiber-Skeletal muscle fibers are the individual cells that are bound together in fascicles. Many fascicles are bound together to make a muscle Motor unit-A motor unit consists of a motor neuron and all of the muscle

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

Activity 2 7) In addition to what you saw‚ did you detect any smells? Describe them. At what point in the observation process did you detect them? Yes. In a little far distant I smell only gasoline when the car driven around and also when filling gasoline to my car. 8) If you used the candle‚ what color was the molten wax? If you looked at something in the environment (a dog‚ bird‚ the sky‚ clouds)‚ provide details...color‚ texture‚ shape‚ size‚ etc. I believe the candle contains carbon

transmitter in the central nervous system. Some species have evolved to block motor activity of their prey by releasing toxins. Some others from coral and plants use different blockage that is induced by cholinergic agents for protect themselves from predation. The high affinity and selectivity of these toxins enabled the type of ACh receptors to emerge as the first chemically characterized neurotransmitter receptor. 2.

months of research and experiments‚ I have 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
