Somatosensory system

They explain how the activity system define a group of people who share a common goal or motive. I completely agree on how an activity system allow certain communities are structurally connected. This is a great way to help you understand community relationships. Activity system is a good system because it “sees all aspects of activity as shaped over time by people’s social interactions with each other and the tools they use” (1). Everyone is in an activity system even if you don’t realize it.…

How Shake Shingle Metal Roofing Compares To Wood Shakes If you love the look of a wood shake roof but hate the thought of all the maintenance a wood roof needs, then you should consider getting a shake shingle metal roof instead. You'll have the look you like, but none of the upkeep required for real wood. Here's how the two types of roofing compare. Appearance You may imagine metal roofing to be in long sheets like you see on barns, but it actually comes in different forms. The metal can be…

Fundamentals of a Roof Warranty Learn the basics of roof warranties and what homeowners should know before they buy. Roofing contractors and roofing material manufacturers both offer a variety of warranties designed to protect their customers from incurring excessive costs in the event of roof damage. However, it is essential for homeowners to understand a few basics about warranties, including what they are and are not, why reading the fine print is important, and how a warranty can benefit…

shows the motor and sensory topographic organization through the use of a homunculus. The homunculus in the motor system figure is correct in both pathways due its somatosensory nature. There is evidence though that while this map technically is correct in broad terms, the M1 somatotopic map is much more complex and non-linear then this. It was originally thought that the motor system had sequential operations that were encoded at each step by a different neuronal population and its only role…

3 major types of neurons? How are they functionally different? Why are the functional differences important? There are 3 major neurons that the nervous system uses to carry information throughout the body; sensory neurons, interneurons, and motor neurons. Each type of neuron, all functionally different, interacts with the central nervous system, the brain, and the muscles of the body. Some vary in shape and sizes as well as differ in simplicity and complexity. Neurons play a big role in…

20-40 years old, 40-60 years old and 60+ year old are all tested then the youngest age group of 0-20s year old will have the higher timed results than the eldest age group 60+ year olds because age affects balance related senses such as vestibular system. The vestibular cells die with age and the cerebellum cells can also be affected by age and drugs for arthritic pain. The results showed that the highest average result was the 0-20 year olds (47.75 seconds), then the 40-60 year olds (40.5…

summarized by the theory of across-neuron response pattern (ANRP). Which states a stimulus will activate a uniquely different set of patterns to discriminate between another stimuli. This is depicted by the absolute difference of neural mass. Somatosensory system codes for the experience of three main types of exteroceptive input; mechanical stimuli (touch), thermal stimuli (temperature) and nociceptive stimuli (pain). Which all require a distinct process. Conscious exteroceptive input is…

brainstem and it controls motor activity, appetite, and sleep arousal responses. After the midbrain comes the limbic system it is found in the most inner, central portion of the brain or cortex. The limbic system controls emotion reactivity, attachment, affect regulation, and long-term memory. The limbic system is actually one of my favorite aspects or lobe of the brain. The limbic system is one of my favorites because it is the part that makes us human. It holds our memories, emotions, and…

This is what helps people detect emotions of themselves and others. There is one amygdala on each side of the brain, they are a part of the limbic system, which is responsible for memory and survival mode. They help to store memories that we may not remember, and also to control aggression. http://study.com/academy/lesson/the-amygdala-definition-role-function.html The hypothalamus is a part of the…

Humans have five basic senses: hearing, vision, smell, taste, and touch. The definition of a “sense” is “any system that consists of a group of sensory cell types that respond to a specific physical phenomenon and corresponds to a particular group of regions within the brain where the signals are received and interpreted.” In this paper I will be taking about sensory deprivation which is the lessening or complete loss of senses. I will discuss what hearing, vision, smell, taste, and touch is and…
