Hi Guys This Article Is About PLEURA #snsinstitutions #snsdesignthinkers #snsdesignthinking PLEURA The pleura is a double-layered membrane that surrounds the lungs and lines the chest cavity. It consists of two parts: the visceral pleura, which covers the surface of the lungs, and the parietal pleura, which lines the inside of the chest wall. The pleura helps create a lubricated space, the pleural cavity, that allows the lungs to expand and contract during breathing while minimizing friction between the lung and chest wall. The pleura, the double-layered membrane surrounding the lungs and lining the chest cavity, has a limited blood supply and is sparsely innervated by nerves. 1. Blood Supply: The pleura receives its blood supply from small vessels that branch off from larger blood vessels in the chest wall, diaphragm, and mediastinum. The blood supply is primarily responsible for nourishing the pleural tissues. 2. Nerve Supply: The pleura is innervated by somatic and autonomic nerves. Somatic nerves (intercostal and phrenic nerves) provide sensory input, enabling the perception of pain, pressure, or touch in the pleural area. The autonomic nervous system regulates involuntary functions and influences changes in pleural blood flow and smooth muscle tone. While the pleura does have some sensory nerve endings, it is relatively insensitive to pain. However, inflammation or irritation of the pleura can lead to pleuritic chest pain.

Micturition or urination is the process of emptying urine from the storage organ, namely, the urinary bladder. The detrusor is the smooth or involuntary muscle of the bladder wall. The urethral muscles consist of the external and internal sphincter. The internal sphincter and detrusor muscle are both under autonomic control. The external sphincter, however, is a voluntary muscle under the control of voluntary nerves. The bladder normally accommodates up to 300-400 ml in adults. When the bladder is distended it sends signals to the brain, which is perceived as the 'full bladder' sensation. The process of emptying the urine into the urethra is regulated by nervous signals, both from the somatic and the autonomic nervous system. The autonomic nervous system comprises both the sympathetic and the parasympathetic nervous system. Bladder Filling and the Guarding Reflex The filling phase is characterized by voluntary contraction of the external urethral sphincter, with sympathetic contraction of the inner urethral sphincter. The sympathetic nervous system also enables the detrusor to distend without reflex contractions, unlike that which happens in most voluntary muscles. Urethral reflexes, called ‘the guarding reflex,’ also play a part in inhibiting involuntary bladder emptying during this process. The afferents are all conveyed through the pelvic nerves to initiate a spinal reflex. #snsinstitutions #snsdesignthinker #designthinking #snscop

Are you easily stressed and tend to overthink things? Let me help you find freedom amongst all the noise so that you can you live with purpose, passion & peace.
Are you a mouth breather? You are missing out on the benefits of nitric oxide. Nitric oxide is vital for vasoregulation (the opening and closing of blood vessels), homeostasis (physiological balance), neurotransmission (the meaning system within the brain), immune defence, and respiration. It aids in preventing high blood pressure, lowering cholesterol, maintaining youthful and flexible arteries, and preventing artery clogs. These advantages can reduce the risk of heart attacks and strokes. Try this… ⏳ Set a timer for 5 minutes 🎵 Put on some relaxing music 👃🏻 Breathe slowly in through the nose for the count of 5, sending the breath to the belly 😮💨 Slowly release the breath through the nose and feel the relaxation with every out breath If you’d like some extra help with this, check out my weekly Regenerative Breathwork Journeys using the link in the comments. Breathe right, live well! 💙 #NitricOxideBenefits #HeartHealthMatters #BreathworkHealing

The vagus nerve, also known as the tenth cranial nerve or simply the "wandering nerve," is one of the longest and most complex nerves in the human body. It originates in the brainstem and extends down through the neck, chest, and abdomen, branching out to various organs and tissues along the way. The vagus nerve is a key component of the parasympathetic nervous system, which is responsible for regulating many vital bodily functions. It plays a crucial role in controlling the heart rate, digestion, respiratory rate, and various other involuntary processes. Here are some important functions and roles of the vagus nerve: 1️⃣ Heart Function: The vagus nerve helps regulate the heart rate by sending signals to the sinoatrial node, which is responsible for initiating the heartbeat. It helps maintain a balance between the sympathetic and parasympathetic systems, influencing heart rate variability and overall cardiovascular health. 2️⃣ Digestive System: The vagus nerve plays a vital role in controlling digestion by transmitting signals to the stomach, liver, gallbladder, and intestines. It helps stimulate the release of digestive enzymes, promotes peristalsis (muscle contractions), and supports overall gastrointestinal function. 3️⃣ Respiratory System: The vagus nerve contributes to the regulation of breathing. It influences the smooth muscles of the airways, helping to control the depth and rate of respiration. 4️⃣ Emotional Regulation: The vagus nerve is involved in the communication between the brain and various organs, including those responsible for emotions. It plays a role in the body's stress response, and stimulating the vagus nerve can activate the relaxation response, promoting a sense of calm and well-being. 5️⃣ Inflammation and Immune Response: The vagus nerve has been found to have anti-inflammatory effects. Research suggests that stimulating the vagus nerve through techniques like deep breathing may have various potential benefits, including reducing anxiety. #VagusNerve #ParasympatheticNervousSystem #HeartFunction #DigestiveSystem #RespiratorySystem #EmotionalRegulation #Inflammation #WellBeing
