Mechanism of pain | Analgesic system | Pain PhysiologyFatima Mangrio
This slideshare describes pain transduction which is the mechanism by which nociceptors depolarize to reach threshold, so that a pain signal can be transmitted to the brain. When the signal reaches the brain, the person becomes consciously aware they are in pain - this is called perception.
Pain sensation is an unpleasant sensation produced by damaged tissues.
It differs from other sensations because its purpose is not to inform the higher centers about the quality of pain.
Physiology of Pain, Characteristic of pain, Basic consideration of nervous system, Pain receptor, Mechanism of pain causation, Theories of pain, Pathways of pain, Pain Receptors
Pain is defined as unpleasant and emotional experience associated with or without actual tissue damage.
Pain sensation is described in many ways like sharp, pricking, electrical, dull, shooting, cutting, stabbing, etc
As such pain is typically associated with noxious stimuli, events that are potentially or actually damaging to tissue

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

5. Definition
pain perceived at a location other than the site of the painful
stimulus.
Irritation of a visceral organ frequently produces pain that is felt
not at that site but in some somatic structure that may be a
considerable distance away. Such pain is said to be referred to
the somatic structure.
also called reflective pain
7. Referred pain mechanism
(Dermatomal rule)
Dermatomal rule
- When pain is referred, it is usually to a structure that developed
from the same embryonic segment or dermatome as the structure in
which the pain originates. This principle is called dermatomal rule
FOR INSTANCE:
the heart and the inner aspect of left arm
Testicle & ureter+kidney(from urogenital ridge)
8. Referred pain mechanism
(Convergence– projection theory)
Convergence– projection theory
Second mechanism for referred pain may be convergence
of somatic and visceral pain fibers on the same second-
order neurons in the dorsal horn that project to the
thalamus and then to the somatosensory cortex (Figure 10–
3). This is called the convergence– projection theory.
9. Referred pain mechanism
(Convergence– projection theory)
Somatic and visceral neurons converge in lamina I–VI of the
ipsilateral dorsal horn
Neurons in lamina VII receive afferents from both sides of the
body
explains referral of pain to the side opposite that of the source of pain
i. e. affected organ.
12. Convergence– projection theory
If prolongation of visceral stimulus
facilitation of the somatic fiber endings
stimulate the second order neurons
brain interprets activity in a pathway as
arising from somatic sources
Referred pain in somatic area
The somatic nociceptive fibers normally do not activate the
second-order neurons. But……..
13. Note
However, sites of referred pain are not stereotyped, and
unusual reference sites occur with considerable frequency.
FOR INSTANCE
Cardiac pain, for instance, is usually referred to Upper chest/left limb
But it may be referred to the right arm, the abdominal region, or even
the back and neck.
15. Visceral Pain
Pain from the different viscera of the abdomen and chest .
transmitted through small type C pain fibers
Causes of True Visceral Pain :
1. Ischemia
2. Chemical Stimuli
3. Spasm of a Hollow Viscus
4. Overdistention of a Hollow Viscus
16. Localization of Visceral Pain
Pain from the different viscera is frequently difficult to localize
because :
1. patient’s brain does not know from firsthand experience that
the different internal organs exist.
2. sensations from the abdomen and thorax are transmitted
through two pathways to the central nervous system—the
true visceral pathway and the parietal pathway.
17. True visceral pain is transmitted via pain sensory fibers within the
autonomic nerve bundles, and the sensations are referred to surface
areas of the body often far from the painful organ.
parietal sensations are conducted directly into local spinal nerves
from the parietal peritoneum, pleura, or pericardium, and these
sensations are usually localized directly over the painful area.
18. Localization of Referred Pain
Transmitted via Visceral Pathways.
person generally localizes visceral in the dermatomal segment
from which the visceral organ originated in the embryo.
Pain from the viscera is frequently localized to two surface
areas of the body at the same time because of the dual
transmission of pain through the referred visceral pathway and
the direct parietal pathway.
19. Examples
Upper chest/left limb
o Myocardial ischaemia
Right tip of scapula
o Liver, gallbladder
Left shoulder
o Thoracic diaphragm,
Spleen (Kehr's sign, lung
Back
o Pancreas
Umblicus
o Small intestine ;appendex

21. Importance
Knowledge of the different types of referred pain is important in
clinical diagnosis because in many visceral ailments the only
clinical sign is referred pain.
