The sternocostal joints are the articulations between the sternum (breastbone) and the costal cartilages of the ribs. These joints are classified as synovial plane joints, except for the first sternocostal joint, which is a cartilaginous joint (synchondrosis). They play a key role in the mechanics of breathing, allowing slight movements of the ribs during inspiration…
Anatomy of Rectus Femoris Muscle The rectus femoris muscle is one of the four quadriceps situated in the front of the thigh. It is unique among the quadriceps as it crosses both the hip and knee joints, making it a biarticular muscle. This muscle causes two actions, it allows the hip to flex and the…
Bone pain refers to discomfort or aching sensations that originate from the bones. It can result from various causes, including injuries (like fractures), medical conditions (such as osteoporosis, arthritis, or bone infections), or certain cancers. Unlike muscle or joint pain, bone pain is often deeper, sharper, or more intense and may persist even at rest….
Muscle pain in the leg, also known as myalgia, is a common issue that can result from various causes such as overuse, muscle strain, dehydration, or minor injuries. It may also be linked to underlying conditions like poor circulation, nerve issues, or nutritional deficiencies. The pain can range from mild discomfort to sharp or throbbing…
What is a Thigh Muscle Pain? Thigh muscle pain, also known as muscle pulls or tears, typically occurs when a thigh muscle is overextended, causing the muscular tissue to rip during an action like running or kicking a ball. They frequently appear close to where the muscle attaches to the tendon’s thick, fibrous connective tissue….
The atlanto-occipital joint is the articulation between the atlas (C1 vertebra) and the occipital bone of the skull. It is a synovial joint that allows for nodding movements of the head, such as flexion (“yes” motion) and slight lateral tilting. This joint is stabilized by ligaments, including the anterior and posterior atlanto-occipital membranes, and plays…
What is Arm Muscle Pain? Arm muscle pain is characterized as discomfort and pain felt anywhere along the arm, sometimes extending to the wrist, elbow, and shoulder joints. There are several reasons why this pain arises, but the most frequent ones are pain or overuse. Depending on the cause of the arm, the pain may…
The carpometacarpal (CMC) joints are the articulations that connect the hand’s carpal (carpals) and metacarpal (metacarpals) bones. Five carpometacarpal joints are known to exist, with the thumb’s carpometacarpal joint—also referred to as the trapeziometacarpal joint—being the most specialized and flexible. Introduction The proximal bases of the five metacarpal bones and the distal row of carpal…
Gracilis muscle pain refers to discomfort or soreness in the long, slender muscle located in the inner thigh. This pain is often caused by overuse, strain, or injury from activities involving repetitive leg movements, such as running or cycling. It may result in inner thigh stiffness, soreness, and difficulty with leg motion, requiring proper diagnosis…
The human body contains numerous joints, which are categorized based on their structure and function. Here is a comprehensive list of joints in the body, grouped by region: Skull (Cranial and Facial) Neck Vertebral Column (Spinal Joints) Thorax Shoulder and Upper Limb Pelvis Hip and Lower Limb This list covers all the major joints in…
