Joint account

Healthy joint The knee joint is a synovial joint and connects the femur to the tibia and consists of two joints the tibiofemoral joint, which joins the tibia to the femur and the patellofemoral joining the kneecap to the femur. These two joints work together to form a hinge joint allowing the knee to bend and straighten and to also rotate slightly from side to side. Muscles There are two main muscles groups of the knee, the hamstrings, quadriceps and muscles of the calf all work to flex,…

knee injury in which a piece of the meniscus is torn. The meniscus is a thick, rubbery, wedge-shaped cartilage in the knee. Two menisci are located in each knee. They sit between the upper bone (femur) and lower bone (tibia) that make up the knee joint. Each meniscus acts as a shock absorber for the knee. A torn meniscus is one of the most common types of knee injuries. This injury can range from mild to severe. Surgery may be needed for a severe tear. CAUSES This injury may be caused by any…

Shin splints are a pain in the shin and lower leg that occur when muscles in that area are overworked. It isn’t just a “sore” muscle. It is sharp pain that could occur during and after physical activities (depending on the severity). The pain associated with shin splints results from excessive amounts of force on the tissues attaching the shin bone to the muscles surrounding it. The excessive force causes the muscles to swell and increases the pressure against the bone, leading to pain and…

By looking at the fetal pig and its muscle structure, researchers and individuals are able to gain a better understanding of what human muscles look like, where they are located, and how they function. The muscles that were labeled in the dissection are important factors in the movement of the individual. The muscles work together though antagonism. Antagonism works when one muscle, such as the extensor carpi radialis contracts, and the flexor carpi radialis relaxes, allowing the hand to extend.…

Many people are familiar with sports that involve throwing a ball like baseball, softball, tennis, and golf; although these sports have nothing in common, they have one thing similar. Medial epicondylitis, also known as golfer’s elbow is an inflammation of the tendons in the inside park of the elbow. Although golfers elbow doesn’t seem sever like tearing an acl, an injury is an injury. Golfers elbow is extremely common in almost every sport, but it is frequently caused by extreme force or…

Anterior Tibiofibular Ligament The anterior tibiofibular ligament is often referred to as the high ankle ligament, and it is the one that is damaged when the foot is stuck on the ground and rotated inwardly. The ankle is a hinge joint that connects the foot and the leg, allowing up and down movement. The tibia and fibula bones of the leg form a slot where the talus bone of the foot fits between them. The talus is held to the tibia and fibula by ligaments. Anterior Tibiofibular Ligament The…

It is possible to dislocate the bones within the midfoot joint complex (aka Lisfranc joint) of the foot: This joint complex consists of the ligaments and bones that connect the forefoot to the midfoot. Lisfranc injuries include strains and tears to the ligament itself in addition to bone dislocations and fractures. The Role of the Midfoot As an individual walks, the midfoot is responsible for transferring the forces that the calf muscles generate to the front of the foot. Furthermore, the…

the big toe begin to deviants from its axis and point toward the pinky toe. This causes a bony protrusion to stick out from the side of foot, on the joint of the hallux, or large toe. This is usually in women, women who wear pointy toed shoes, tight-fitting shoes, or high-heeled shoes. These types of shoes can cause deviations to occur on the joint. This can cause severe pain, and a n un-pleasing look to the foot. The bunions are caused by swelling and inflammation. Pain is usually felt a the…
