What are muscular knots? Muscle knots, also known as myofascial trigger points, are tight, sensitive areas of muscle that form when muscle fibers tense up and fail to release. These knots can develop due to overuse, poor posture, stress, or injury, and are commonly found in the neck, back, and shoulders. Muscle knots can lead…
Introduction The subtalar joint, located just below the ankle joint, plays a critical role in foot and ankle biomechanics. It connects the talus (a bone in the foot) with the calcaneus (heel bone), enabling the complex movements of inversion and eversion, which allow the foot to adapt to uneven surfaces. As a synovial joint, this…
What is a Carrying Angle of The Elbow? The carrying angle is the angle formed between the long axis of the humerus and the forearm when the arm is extended and the palms face forward. According to anatomy, an adult human’s carrying angle is generally 10° for men and 13° for women. In addition to…
Ankle joints are complex mechanisms that play important roles in allowing movement in the lower extremities and providing stability. Several ligaments support the ankle’s overall stability by joining the bones and ensuring optimal joint function. The anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL), and calcaneofibular ligament (CFL) comprise the lateral (outside) portion of the ankle joint. These ligaments contribute lateral support to the ankle by attaching the talus and calcaneus, two-foot bones, to the fibula, one of the two lower leg bones. Ankle ligament overstretching or taking produces a sprain. Ankle sprains are…
The shoulder joint, also known as the glenohumeral joint, is a ball-and-socket joint that involves the humerus (upper arm bone) and the scapula (shoulder blade). It is one of the most mobile joints in the human body, allowing for a wide range of movements such as flexion, extension, abduction, adduction, rotation, and circumduction. Introduction The glenohumeral joint, which is situated in the shoulder, can move in a wide variety of ways….
Introduction Patella Alta, commonly referred to as a high-riding patella, is a condition in which the kneecap (patella) is positioned higher than its normal alignment in relation to the femur. What Is Patella Alta? The quadriceps tendon surrounds the patellofemoral joint, which is made up of the kneecap lying in a dip on the front…
Introduction The knee joint is one of the largest and most complex joints in the human body, playing a crucial role in our ability to move and bear weight. It connects the thigh bone (femur) to the shin bone (tibia) and includes other structures like the kneecap (patella) and cartilage, which help in smooth movement….
Introduction A reflex is an uncontrollably stereotyped, involuntary response to a specific sensory stimulus. Every healthy individual possesses a variety of reflexes. Actually, the majority of them are innate. An impulse is dealt with by reflex arcs prior to it reaching the brain. The way the reflex reaction is shaped depends in large part on…
Neurotmesis is a type of severe peripheral nerve injury that results from nerve transection. Neurotmesis involves cutting off the entire nerve, affecting the endoneurium, perineurium, and epineurium. The myelin sheath, connective tissues, and axon are ruptured as a result of neurotmesis. When a peripheral nerve injury is severe enough to cause neurotmesis, the affected person as…
What is an Axonotmesis? The term “axonotmesis” describes the anatomical disruption of an axon that does not, or only partially, disturb the framework of connective tissue. Axonotmesis is a condition in which a peripheral nerve in one of the body’s limbs is injured. This type of injury results in damage to the axons and their…
