Hip jointLucidante1
油
The hip joint is a ball and socket synovial joint that connects the lower limb to the pelvis. It is formed by the spherical head of the femur articulating with the acetabulum of the pelvis. Strong ligaments including the iliofemoral, ischiofemoral, and pubofemoral ligaments reinforce the joint capsule to provide stability while allowing flexion, extension, abduction, adduction, and rotation movements. The hip joint has an extensive blood supply and is innervated by nerves from the lumbar plexus and sacral plexus.Wrist and radioulnar joints

The axillary nerve arises from the posterior cord of the brachial plexus, deriving from cervical nerves C5 and C6. It supplies the deltoid and teres minor muscles. It passes through the quadrilateral space behind the humerus and divides into anterior and posterior branches. The anterior branch innervates the deltoid muscle. The posterior branch supplies the teres minor and posterior deltoid, and continues as the lateral cutaneous nerve, providing cutaneous innervation to the lateral arm. Injury results in paralysis of the deltoid and teres minor, causing weakness of shoulder abduction, flexion, extension and rotation.Anatomy of shoulder joint
Anatomy of shoulder jointBipulBorthakur
油
The shoulder joint is formed by the articulation of the glenoid cavity of the scapula and the head of the humerus. It is a synovial, polyaxial ball and socket joint. The glenoid fossa is too small and shallow to stably hold the humeral head, so the joint is inherently weak. Stability is provided by the joint capsule, glenohumeral ligaments, labrum, rotator cuff muscles, and other accessory ligaments. Injuries like dislocations or rotator cuff tears can compromise the stability of the shoulder joint.Anterior compartment of arm & cubital fossa Dr.N.Mugunthan

This document provides information on the biomechanics of the wrist and hand complex. It describes the bones, joints, ligaments, muscles, and range of motion of the wrist, hand, fingers, and thumb. Key points include that the wrist is a complex of two joints (radiocarpal and midcarpal) that allow flexion/extension and radial/ulnar deviation. The hand has 19 bones and joints distal to the carpals that form transverse and longitudinal arches to enhance grip. Each finger has carpometacarpal, metacarpophalangeal, and interphalangeal joints while the thumb only has one interphalangeal joint. Ligaments and muscles work together to provide stability andELBOW JOINT final.pptx

This document describes the anatomy of the elbow joint, proximal radioulnar joint, and distal radioulnar joint. It details the articulating bones, ligaments, synovial membranes, movements, and important relations of each joint. The elbow is a hinge joint that allows flexion and extension. The proximal and distal radioulnar joints are pivot joints that facilitate pronation and supination of the forearm through rotation of the radius around the fixed ulna. Key ligaments include the medial and lateral collateral ligaments of the elbow and the annular ligament surrounding the head of the radius.Biomechanics Of Wrist.pptx

The wrist complex consists of two joints, the radiocarpal and midcarpal joints. It controls muscle tension and allows fine grip adjustment. The wrist muscles are designed more for balance than torque. The radiocarpal joint involves the radius, triangular fibrocartilage complex, scaphoid, lunate and triquetrum. It is obliquely angled with an average 23 degree inclination of the distal radius. The midcarpal joint connects the scaphoid, lunate and triquetrum to the distal carpal row. The wrist has many intrinsic and extrinsic ligaments and is considered a biaxial joint allowing flexion/extension and ulnar/radial deviation.II BOT_Wrist Biomechanics and Applied Anatomy_Punita V.

The wrist joint is formed by the distal end of the radius and articular disk proximally and the proximal row of carpal bones distally. It allows flexion, extension, radial and ulnar deviation. The radiocarpal joint is formed by the radius, lunate and scaphoid while the midcarpal joint connects the proximal and distal rows of carpal bones. Ligaments like the scapholunate and lunotriquetral stabilize the joints. Muscles like flexor carpi radialis and extensor carpi radialis longus control wrist movements. Wrist instability can occur from ligament injuries or fractures leading to carpal misalignment and arthritis.RADIO-ULNAR JOINT IS THE JOINT PRESENT IN HUMAN UPPER LIMB

The articulation between the radius and ulna is facilitated by ligaments and can be divided into three sections - proximal, middle, and distal. The proximal radioulnar joint is a pivot joint between the head of the radius and radial notch of the ulna, connected by the annular ligament. The middle radioulnar joint connects the shafts via the oblique cord and interosseous membrane. The distal radioulnar joint is a pivot joint between the head of the ulna and ulnar notch of the radius, connected by the volar and dorsal radioulnar ligaments and articular disk.RADIO-ULNAR JOINT IS THE JOINT OF UPPER LIMB IN HUMAN BODY

An ancient System for holistic health (mental and physical) and wellbeing, is a scientific art of living with harmony (connecting) of mind and body. Although much more ancient than Patanjali, who documented yoga systematically about 2000 years ago, Patanjali is often referred to as the "father of modern yoga."
Yoga postures are commonly depicted in ancient paintings, carvings, and sculptures in almost all civilizations and religions, thus Yoga cant be described as an act of Hinduism. It originated long before any religion on Earth, with the emergence of life on the Planet. All yoga poses are natural, and what is not natural is not yoga; it is油Viyoga.
Besides Vedic Yoga, Hatha, Vinyasa, Ashtanga, Iyengar, Yin, Restorative, Kundalini, Bikram, Sahaj, and Power yoga are some popular types.
Vinyasa油Yoga is the closest form to Vedic Yoga; it is known for its flowing movements, not very rigorous, not too much straining, actions flow with the breath.
Though all yoga may lead to meditation (Dhyan) for your inner upliftment, it is not the same as described in Hinduism for self-liberation.
In Hinduism, different paths of life looking distinct but can be practiced all together, they are: Karma Yoga (selfless action and service), Bhakti Yoga (devotion and love for God or Godly power), Jnana (Gyan) Yoga (gaining knowledge for self-realization through wisdom), Dhyan Yoga (meditation) and Kriya Yoga (optimum utilization of your vital and muscular energy).油

Open PPT for detail description: Peptic Ulcer Disease (PUD)
Peptic ulcer disease refers to mucosal erosions equal to or greater than 5 mm in the stomach or proximal duodenum, caused primarily by an imbalance between gastric acid/pepsin secretion and mucosal defense mechanisms. The most common etiologies include Helicobacter pylori infection, chronic use of NSAIDs, and physiological stress.
Classification of Peptic Ulcers
Based on Location
Gastric Ulcers Occur in the stomach lining.
Duodenal Ulcers Occur in the first part of the small intestine (duodenum).
Based on Etiology
H. pyloriAssociated Ulcers
NSAID-Induced Ulcers
Stress-Related Mucosal Disease (SRMD)
ZollingerEllison Syndrome (gastrinoma-related)
Cushings Ulcer (due to intracranial injury)
Curlings Ulcer (seen in burn patients)
Pharmacological Management
1. Acid Suppression Therapy
Class Examples Mechanism
Proton Pump Inhibitors (PPIs) Omeprazole, Pantoprazole Irreversibly inhibit H+/K+ ATPase pump
H2-Receptor Antagonists Ranitidine, Famotidine Block histamine-mediated gastric acid secretion
2. Mucosal Protective Agents
Class Examples Mechanism
Prostaglandin Analogues Misoprostol Increases mucus & bicarbonate; decreases acid; protects mucosa
Mucosal Coating Agents Sucralfate Forms protective barrier over ulcer site
Bismuth Compounds Bismuth subsalicylate Antimicrobial, mucosal protective, and anti-inflammatory
3. Eradication Therapy (for H. pylori)
Combination of:
PPI + Two Antibiotics (e.g., amoxicillin + clarithromycin OR metronidazole + tetracycline)
Duration: 714 days depending on local guidelines
See BNF regimens above for detailed protocols
4. Cytoprotective/Adjunctive Agents
Class Examples Role in PUD
Somatostatin Analogues Octreotide Used in bleeding ulcers; reduces splanchnic blood flow and gastric secretions
Antacids Magnesium hydroxide, Aluminium hydroxide Neutralize gastric acid; provide symptomatic relief
Non-Pharmacologic Measures
Avoid NSAIDs, smoking, alcohol, and spicy foods
Small, frequent meals in symptomatic patients
Stress reduction
Endoscopic therapy in case of bleeding or perforation
Surgical Indications (rarely needed)
Perforated ulcer
Gastric outlet obstruction
Refractory ulcers not responding to medical therapy
Severe bleeding unresponsive to endoscopic management
Summary
Peptic ulcer disease is primarily driven by H. pylori infection and NSAID use, with duodenal ulcers more common than gastric. Treatment is tailored based on etiology and includes acid suppression, H. pylori eradication, and mucosal protection. Advanced cases may require somatostatin analogues for hemorrhage control or surgery for complications. Prostaglandin analogues like misoprostol are especially valuable in preventing NSAID-induced ulcers.Computer aided formulation development optimization
