definition-Rickets is a skeletal disorder that’s caused by a lack of vitamin D, calcium, or phosphate. These nutrients are important for the development of strong, healthy bones. People with rickets may have weak and soft bones, stunted growth, and, in severe cases, skeletal deformities. Cause- Rickets is a bone disorder caused by a deficiency of…
What is a Muscular System? Origin and Insertion Points Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain, it is known…
DEFINITION : In physics, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate forces are applied to them. Mechanical Properties: Non-Linear Elasticity Mechanical Properties: Viscoelasticity There are three major characteristics…
Pulleys play a significant role in biomechanics, particularly in the context of human movement and the musculoskeletal system. They are mechanical devices consisting of a grooved wheel and a rope, cable, or belt that runs along the groove. Pulleys are designed to change the direction of a force and provide mechanical advantage, making it easier…
Definition: Peroneal tendonitis occurs when the peroneal tendons become inflamed. This happens when there is an increased load and overuse of the tendons, leading to them rubbing on the bone. Peroneal tendinitis is a condition that can be acute or become chronic (peroneal tendinopathy) whereby there is an irritation to one or both peroneal tendons…
Definition of Ankle Sprain : –An ankle sprain is an injury to the tough bands of tissue (ligaments) that surround and connect the bones of the leg to the foot. The injury typically happens when you accidentally twist or turn your ankle in an awkward way. This can stretch or tear the ligaments that hold…
Introduction: The hip joint is a ball-and-socket joint that connects the thigh bone (femur) to the pelvis, enabling a wide range of movement. It plays a crucial role in supporting the body’s weight and facilitating activities like walking, running, and jumping. Structures of the Hip Joint : Articulating Surfaces : Ligaments: Intracapsular: Extracapsular: Stabilising Factors:…
Definition Baxter’s neuropathy is a nerve entrapment syndrome that results from the compression of the inferior calcaneal nerve. Selective fatty atrophy of the abductor digiti minimi muscle is the unique sign of this neuropathy. Baxter’s Entrapment is an entrapment (or compression) of the Inferior Calcaneal Nerve just under the base of the arch of the…
INTRODUCTION: A lever is a rigid bar that moves on a fixed point called the fulcrum when a force is applied to it. Movement is made possible in the human body by lever systems which are formed by our muscles and joints working together. An understanding of the lever systems in the body helps us…
DEFINATION: Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of vertigo, which is a symptom of the condition. Though not fully understood, BPPV is thought to arise due to the displacement of otoconia (small crystals of calcium carbonate) from the maculae of the inner ear into the fluid-filled semicircular canals. These semicircular canals…
