Introduction The anterior longitudinal ligament is a robust band of connective tissue that runs down the front of the spinal column’s vertebral bodies. It prevents excessive movement and protects against injury by stabilizing and supporting the spine. The ligament is a vital part of the spinal column and is essential to keeping the spine in…
Introduction The central nervous system (CNS) is a division of the nervous system that analyses and integrates different intrapersonal and extrapersonal information and produces a coordinated reaction to these stimuli. The brain and spinal cord are the two continuous central nervous system (CNS) organs. They are contained in two bony structures, the skull, and the…
Knee Extension Knee Extension refers to the movement of straightening the knee joint, typically performed by the quadriceps muscles at the front of the thigh. It is a vital motion for activities like walking, standing, and climbing stairs. Knee extension exercises are often used in rehabilitation to restore strength and mobility after injury or surgery….
Introduction The pubofemoral ligament is a strong, triangular ligament located on the anterior side of the hip joint. It connects the pubic bone to the femur and helps prevent excessive hip abduction and extension, providing stability to the joint. Pain, stiffness, and trouble moving can also be symptoms of pubofemoral ligament injuries. Complete recovery requires…
Ankle Dorsi Flexion Ankle dorsiflexion is the movement of pulling the toes upward toward the shin, decreasing the angle between the foot and the lower leg. It is essential for walking, running, and maintaining balance. Ankle Dorsi Flexion and Planter Flexion: What Are They? Two essential ankle joint movements, ankle dorsiflexion, and plantarflexion, are necessary…
Introduction The iliofemoral ligament, also known as the Y-ligament of Bigelow, is a strong, triangular ligament that connects the ilium to the femur. It is located at the front of the hip joint and plays a crucial role in stabilizing the hip by preventing hyperextension. Its unique Y-shaped structure provides significant support during standing and…
What is a Annular Ligament Injury? An annular ligament injury involves damage to the strong band of tissue that encircles the head of the radius, securing it to the ulna and stabilizing the elbow joint. It often results from trauma, such as a fall or sudden pulling motion, commonly seen in young children (referred to…
Introduction The annular ligament is a strong, circular band of fibrous tissue that wraps around the head of the radius, securing it to the ulna at the proximal radioulnar joint. It allows the radius to rotate smoothly during forearm movements like pronation and supination while maintaining joint stability. The annular ligament is made of thick…
Introduction The radial collateral ligament (RCL) is a strong, fibrous band located on the lateral side of the elbow joint. It connects the lateral epicondyle of the humerus to the annular ligament, providing stability to the outer elbow and supporting the joint during activities involving arm movement. It primarily resists excessive varus forces, preventing the…
Introduction The Posterior Cruciate Ligament (PCL) is one of the four major ligaments in the knee, located at the back of the joint. It connects the femur (thigh bone) to the tibia (shin bone) and primarily functions to prevent the tibia from moving too far backward. The PCL provides stability to the knee, especially during…
