Type Of Sensation In The Body
Pain sensation is one of the most common types of sensation which is experienced by all individual. The pain sensation I have experienced is due to sudden fall in the floor. The sensation which I have experienced includes trouble in grippling objects with hand, feeling of pins or needles in the fingers and swollen feeling. I have also experienced tingling in the finger especially in the middle and the index finger. The pain sensation in hand and wrist increased due to excessive stress in the hand and continuous working (Cavalli et al., 2019).
It is determined that the sensation of pain begins with the transaction of stimulus in the peripheral region and the stimulus is converted into electrical signals that travel in the central nervous system and ultimately activate the peripheral receptors by thermal, mechanical and chemical stimulus. The pain sensation is associated with the activation of a receptor located in the primary afferent fibre which is unmyelinated C fibre and myelinated A σ-fibre. In the absence of pain both the type of nociceptive receptor remains in the silent stage during the normal homeostasis and activated when there is a potential noxious stimulus triggering the pain sensation. The perception is felt by a series of sensory events which is required for detecting the type of sensation and pain by the brain and thereby providing response to the threat. The 3 types of perception of pain includes- the pain sensitivity which is considered to be the first stage of pain, the second stage where the signal is transmitted for peripheral region to the dorsal horn and it is located in the spinal cord and the third stage the transmission of signals is found to travel to the higher region of brain with the help of central nervous system (Cavalli et al., 2019). There are two routes which help in developing the pain response within the body which includes ascending and descending pathways. The sensation of pain can be classified depending upon the region of the body involved and the duration of the pain. I have experienced acute pain due to a sudden fall and the region of pain was visceral pain. The sensation of pain is developed due to three events which consist of transduction, transmission and modulation due to the presence of noxious stimuli (Bates et al., 2019).
The two different pathways include spinoreticular tracts and spinothalamic tracts which transmit the impulse to the thalamus and brainstem. The dual-phase of acute pain is mediated by two types such as primary afferent nerves which helps in transmitting the electrical impulse from the tissues in to the spinal cord. The pain is transmitted through the ascending nerve tract. The delta fibres are larger and are activated by thermal and mechanical stimuli. The C-fibres are found to respond the thermal, mechanical and chemical stimuli and this sensation is associated with lingering and the sensation which is poorly localized which follows first and quick sensation of pain. The spinothalamic input is found to affect the conscious sensation pain (Marchand, 2021).
It is essential to feel the pain as it plays a vital role in providing an alert to the individual and protecting from harmful damage (Yam et al., 2018).
