Feeling is a basic innate response to outside stimuli. It allows for any organism or human to respond to a potentially dangerous situation. Basic responses such as shivering and sweating help keep the body at its optimal temperature so that basic cellular functions can progress properly. Normally nerves transmit signals between the brain and the body to allow for communication and sensory of the outside world as well as internal ques. A vast wiring of peripheral and autonomic nerves, along with the spinal cord and brain, communicate in split second reactions. These split second reactions that control heart rate, fight/flight, body temperature, as well as other reactions we take for granted A network of highly sensitive nerve endings has evolved throughout the body so that we can sense danger and respond in a timely manner. Very basic functions such as irritation to the eye and discomfort to the joints can easily be noticed and fixed because of nerves. For a very small percentage of the population though this is not the case. Congenital Insensitivity to Pain with Anhidrosis (CIPA) is a rare disease that causes the infected to have no reaction to pain and in most cases, lose sense of smell as well.
Congenital Analgesia is a rare condition that prevents people from experiencing senses due to a mutation on the NTRK1 gene is located on the long (q) arm of chromosome 1 between position 21 and position 22 {1}. It is inherited in an autosomal recessive pattern which means that the infected must get the allele from both parents. Someone with only one allele of CIPA is a carrier but does not exhibit signs of the disease.
Mutations in the NTRK1 gene cause a protein not to be activated by phosphorylation (2). Without the protein functio...

... She had frequent high fevers but never showed any signs of sweating or pain throughout the episodes. She was then recorded as self-mutilating body parts and biting off the tips of fingers and tongue (9).
Currently, there is no treatment for Congenital Insensitivity to Pain with Anhidrosis. A person with this condition must constantly manage injuries and infections in order to live a healthy life. Because of this, the infected rarely live past the age of 30 because of the physical toll the body takes on a daily basis (1). Luckily it is a very rare condition and less than 100 cases have been documented in scientific literature (1). Those who are infected with CIPA must take extra precaution but can lead a semi-normal life with the adequate protection. It is still rare at this time that patients will live a normal length life due to multiple complications.
due to the loss of a large amount of blood after having had her throat
...in the times she did this is one of the most accurate descriptions of the rabies virus and not all for dramatic tension and dramatization.
He was diagnosed with paranoid schizophrenia, but some thought he might actually be suffering from drug-induced toxic psychosis. He visited the emergency room for testimonials that bones were coming out the back of his head, someone stole his pulmonary arteries, his stomach was backwards, and his heart stopped beating sometimes. He was also diagnosed with hypochondria, where he believed his heart was in danger of shrinking until disappearance. He then came to the solution that drinking blood of animals or humans would stop the shrinking. He was also interviewed and said that he killed to stay alive. He was admitted to a mental institution and was prescribed antidepressants. He was allowed to leave anytime he wanted. He was left unsupervised and his mother told him that he did not need the
...ing other than a slight sickness. She did everything without thinking.” This last sentence is key, “She did everything without thinking.” This displays that she wasn't thinking at the time of the murder and had no intention to commit murder. Due to the trauma, she could not “think straight”. Thus proving her inability for mind-body coordination.
She was taken to the hospital after she tried to commit suicide, she took a bottle of aspirin. Her reason for taking the full bottle of aspirin was a major headache, which was also alarming to the psychiatrist. The psychiatrist recommended that she be admitted to a mental hospital for women, where she can rest and recover. Another sign of the Borderline Personality Disorder is casual sexuality.
There are multiple feelings, moods, and senses that people use every day. Two of the primary feelings used is
The most common and well described pain transmission is “gate control theory of pain”. This theory was first proposed by Melzack and Wall in 1965 whereby they used the analogy of gate to explain the inhibition of pain which exists within the dorsal horn of the spinal cord. For instance, when tissue damage occurs, substances such as prostaglandin, serotonin, histamine and bradykinin are released from the injured cell. Individual usually consume or apply pain medications such as NSAIDs whereby these medications will cause electrical nerve impulse at the end of the sensory nerve fiber via nociceptor. Nociceptor is a pain receptor that is commonly found in the skin, cornea of eye and organ of motion such as muscles and ligaments. These nerve impulses

As the reader is introduced to the woman we find her talking about very strange and unusual happenings occurring around her. She evens states that she has a condition that signifies insanity, but the doctor would never tell her straight to her face that she was insane. She says, “I think it is due to this nervous condition”(453). This shows that she knows there is something wrong with her. This nervous condition she refers to can only mean that she is having mental problems and is possibly going insane. We can infer this because during this time period, the doctors did not state that someone was insane because they had no medical proof. Instead they would just tell the patients that they have a nervous condition, and send them away. She says, “I always fancy I see people walking in the numerous paths and arbors, but...
The human body has developed a pain response in order to avoid injury. For example, if an individual were to place their hand on a hot oven, the excruciating pain would signal the nervous system to move the hand immediately before experiencing irreversible damage.
These patterns occur only with intense stimulation. Because strong and mild stimuli of the same sense modality produce different patterns of neural activity, being hit hard feels painful, but being caressed does not. It suggested that all cutaneous qualities are produced by spatial and temporal patterns of nerve impulses rather than by separate, modality specific transmission routes. Gate control theory of pain states that stimulation by non-noxious input is able to nullify pain.
...dition, so the doctor thought that this weakness was the reason she died.What really killed her was being put back into the role that was forced and expected of her. When her husband walked in, all of her feminine freedom vanished.
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
First, one must have the five senses; taste, smell, hear, see, and feel. Yes, these are physical aspects, however, these senses are what any human needs to be, human. For example, the human body needs to be able to taste. It must ingest food, and the food must appeal to a decent taste. A human must also be able to smell, so one may smell a poisonous gas, delicious food, or any other stench that may linger in the air. To be able to hear, enables the human to hear danger or a noise that appeals to them. When seeing, danger is also noted as well as the care of others. When one feels, the object that is being felt may make the person feel comfortable. Not only the sense of touching, but feelings.
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.
