Research Question
What is the impact of the distribution of skin receptors in different areas of the body?
Or
How do skin receptors' distribution change in different areas of your body?

Background Research:
Our Skin is the barrier that protects and keeps our internal organs from the outside. It is composed of three different layers:
The Epidermis
The dermis
The Hypodermis
The Epidermis Is the topmost layer, with a main objective of not letting anything that is possibly dangerous from entering our body.
The Dermis is the second layer of skin. It is located below the Epidermis and contains our hair follicles (which sprout on the Epidermis).
The Hypodermis is the lowest and largest layer, containing fat and connective tissues.

The different types of sensory receptors through the skin allow us to sense contact. These receptors provide important information to the brain through sensory neurons. With this, the brain is able to analyze the temperature, pain and pressure of the object which had contact to the skin.
The largest touch sensors we have is the Pacinian Corpuscle or lamellar Corpuscle located on the lowest layer of skin - the hypodermis.
It responds to vibrations on the skin, allowing the sensory neurons (which originate in the spinal cord and stay at the bottom of …show more content…

They are the two most sensitive mechanoreceptors out of all 4, as they have to respond to small and quick vibrations. Merkel's disks are slowly adapting receptors that react to 10-15 Hz vibration, while meissner's corpuscles are rapidly adapting, they react from 20 to 50 Hz vibration. The biggest concentration of mechanoreceptors are on the ridges of the fingertips as lots of vibrations tend to happen daily in these locations. The more the number of mechanoreceptors, the easier it is for the brain to get a lot of information about the object we are having contact with and its

Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell.

The reflex process begins when the tack, or stimulus, makes contact with the integument on the bottom of the foot; this is the arrival of a stimulus. The stimulus’ pathway starts at the epidermis, where it will penetrate all five layers, from the outermost stratum corneum, it travels through the stratum lucidum, stratum granulosum, and stratum spinosum, all the way to the innermost stratum basale. From there, it will continue into the dermis, where there is an extensive network of nerve endings and nerve fibers throughout the two layers of the dermis. The papillary layer contains Meissner’s corpuscles, touch receptors that are sensitive to light touch, which would be able to sense the feeling of the tack making contact with the epidermis. Within the reticular layer are Pacinian corpuscles, touch receptors that can detect deep pressure and vibration, such as the pressure of the tack against the foot.

The skin is an organ and the largest in the body. Not only does your skin protect you from harmful contaminants, such as bacteria and viruses, but it protects your skin from environmental toxins. However, the one thing that harms the skin the most is the sun. Skin cancer has become a very common occurrence in residents of Jasper, Dubois County, and its surrounding areas because we spend a lot of time enjoying the outdoors.

South University Jane Emond NTR 2050 Dr. Weintraub August 3, 2015   The five senses, sight, sound, touch, taste, and smell. All amazing on their own, but when all are working independently of each other properly people can function pretty well. However, when the slightest disruption interferes with how our senses work properly life can become pretty unbearable at times. Just to name a few issues such as the common cold, seasonal allergies, conjunctivitis, and ear infections can very easily cause the balanced system to go out of whack.

Jean Ayres first introduced the world to Sensory Integration (what later would be referred to as Sensory Processing Disorder) in the year 1972 through her five basic postulates. The first of these postulates proposed by Ayres was that a human’s brain could change and develop even past childhood, what we now know as neuroplasticity. Next she explained that in order for senses to properly integrate there must be an interaction between the cortical and subcortical structures of the brain. Higher order areas of the brain, according to Ayres, rely on the lower order regions to properly inhibit or facilitate sensory messages. Additionally she determined that every processed sensation would require the brain to facilitate some input and inhibit another.

Psychology involves using our senses to learn about human behavior, subjects are often observed by physiologists to determine their reactions, measure their emotions and to learn more about typical and atypical human behavior. Part I - The most commonly known and labeled senses are sight, hearing, touch, taste, and smell. Considering this, please address the following a) Do you think that there may be senses which do not necessarily receive information only from the environment, but rather from within us as well?

99). There are three structures involved in the information processing model; sensory register, short-term store and long-term store (Tangen & Borders 2017, p. 99). The sensory model is a way of attaining information through any of the five senses; smell, sound, taste, sight and touch (Tangen & Borders 2017, p. 101). Most information attained through the senses only lasts for up to three seconds (Tangen & Borders 2017, p. 101). However, if attention is paid to the information, it can be processed to the short-term store/ short term memory (Tangen & Borders 2017, p. 101).

When in possession of all five, the realization of the importance of each one separately goes unacknowledged. However, in the absence of a sense, another one becomes stronger. The vision impaired use their ears as a guide to get around, and the hard of hearing use their eyes to communicate through sign language. Considering this, the next time a complaint is brought about a certain stench or an overly loud sound, consider the fortune one holds to have the ability to experience the sensations of the treasured world around us. The five senses: smell, taste, sight, sound, and touch, form the group of fundamental responses the mysterious human body can perform.

The skin is made up of three layers and all the layers have a key role in acting as the defense. The outermost layer which is the epidermis is an actively regenerating layer. This layer keeps on growing and differentiating to maintain the pH and moisture content. The epidermis does not work alone in keeping the skin healthy.

The origins of human skin colour: The origins of human skin colour remained an enigma that was to generate a multitude of misconceptions. The true source of human pigmentation was finally revealed with the discovery of the melanocyte in the 19th century. Once the amino acid tyrosine was identified to be the key enzyme in pigment formation, attention focused on elucidating the chemical structure of melanin, an enterprise that remains incomplete.

They are also constantly being replaced from below as cells from the basal layer of the epidermis multiply and are pushed up to the surface. The basal layer of the epidermis receives its blood supply, nutrients and fluids from the dermis. There are five layers of the epidermis: Stratum Corneum (surface): •
