Achilles tendonitis is a musculoskeletal condition that occurs with overuse and degeneration of your Achilles tendon -- the largest tendon in your body. The American Academy of Orthopaedic Surgeons states that there are two principal types of...
Your arm is the link between your body and your ability to manipulate your environment. Your pecs, back and shoulder muscles must move your hand to the correct position for you to eat, brush your teeth, work, exercise and play sports. Tendons...
The Achilles tendon is the strongest and largest tendon in the body. During running, forces on it can be 10 times the runner's body weight, says Dublin's Trinity College, with forces on the depending on running form as well as foot structure....
Playing sports can keep young athletes active and healthy, but the Milwaukee Kickers Soccer Club warns against ignoring knee pain in young athletes. Early recognition and intervention can help young athletes return quickly and safely to the...
Building the brachioradialis muscle will nicely shape your forearms, reducing the appearance of saggy arms. Although they are not the biggest muscles, strong and conditioned brachioradialis muscles assist your biceps during dumbbell curls,...
Muscles in the forearm not only give your hands the ability to grasp object, but move your hand in various directions. The flexor carpi ulnaris is one of these muscles. Exercising your forearm flexor muscles with light free weights maintains range...
Three muscles comprise "the hamstrings." These posterior leg muscles originate at the bottom of the pelvis from a bony process called the ischial tuberosity. There is one ischial tuberosity on each side of the pelvis, and they are often referred...
The flexor muscles and tendons of the human body act to reduce the angle between the bones making up a joint. The type of therapy used on injuries to the flexor tendons depends on the degree of injury and the stage of healing. The inflammation...
The human endoskeleton provides a framework for body tissues and organs. Bones attach to one another via tough connective tissue called ligaments and by cartilaginous, fluid-filled joints. Muscles attach to bones via tendons so that you can...
According to the American Academy of Family Physicians, tendons are composed of collagen fibers, elastin, proteoglycans and lipids, and are surrounded or sheathed by epitenon, which contains the tendon's blood vessels and nerve supply. Tendons...
The peroneus are a group of muscles that are located to the outer part of your lower leg. These three muscles, peroneus brevis, longus and teritus, extend from your fibula and insert into your tendons in your midfoot and toes. They work together...
Your thigh is made up of several muscle groups that work with your hip and lower leg to produce movement. No single group works by itself in daily activities because all muscles in your body are connected by nerves, blood vessels, and connective...
The group of muscles at the back of the lower leg is commonly called the calf. There are two major muscles, both of which insert into the heel using the Achilles tendon. When the leg contracts, tension is placed on this tendon and enables the...
The two primary muscles in the calf are the gastrocnemius, which is the largest, outermost muscle, and the soleus, which is connected to the tibia and fibula and inserts to the Achilles tendon. While working out to get bigger calf muscles may give...
The knee joint is stabilized by several ligaments and muscles. The anterior (front) of the knee joint is covered by the kneecap, also called the patella, which floats inside the tendon and attaches the quadriceps to the lower leg. The front of the...
Your pectoralis muscle originates along your rib cage, sternum and clavicle and inserts via tendon at your upper anterior humerus. A pectoralis muscle tear, or rupture, is a rare but painful injury and is generally seen in weightlifting. According...
The gastrocnemius, the most prominent muscle of the lower leg, gives the calf its curvy shape. On athletes, the gastrocnemius may appear as two bulbous shapes that meet in the middle of the lower leg to form an inverted "V" shape. In tandem with...
A heel spur is a bony growth that hangs from the heel bone like stalactite, as described in the book "Health Basics." According to Dr. Edward Laskowski at the Mayo Clinic, they are not always painful and, in fact, some may have heel spurs without...
Achilles tendinitis affects both the young and the old, but it is often due to overuse or repetitive stress, such as jumping and running. Symptoms include pain and swelling in the lower leg and back of the heel that worsens during the day and with...
Many factors can cause Achilles tendon pain. According to the website Foot Health Facts, the Achilles tendon is a thick band of tissue that runs down the back of the lower leg. The Achilles tendon links the calf muscles--the gastrocnemius and the...
The anterior arm muscle anatomy is made up of three muscles in the anterior compartment. The biceps brachii, brachialis and the coracobrachialis, located in the upper arm, work together to form the anterior arm muscle anatomy. The biceps muscles...
Two muscles make up the "calf" muscles: the underlying soleus and the outer gastrocnemius. The soleus is only involved in plantar flexion (pointing of the toe). The gastrocnemius does both plantar flexion and knee flexion (bending the knee). This...
Racquetball is a fast-paced sport often played in health clubs. Two to four players can play at a time. The court consists of a floor, ceiling and four walls, and players will use all during a game. Players use a racquet and a ball and work to...
Kipping pull-ups are a method of jerking and bouncing your way through a pull-up instead of using the actual strength and power of your muscles to get your chin over the bar. This can subject your elbow and shoulder joints to a great deal of...
The armpit, also known as the axilla, is the hollow area on the underside of the arm, where the arm and the shoulder join the torso. Numerous structure in the axillas, including blood vessels, nerves, tendons and lymph nodes, can cause armpit pain...
The rectus femoris is one of the muscles in your quadriceps that lies in the middle of your thigh near the surface. The sartorius is a long, thin muscle that runs from the front part of the top of your pelvis, down and around your thigh, and...
A tendon is tough, fibrous tissue that connects a muscle to bone. Tendons transfer the energy generated by muscle contraction to bone, thereby producing movement. Overuse or an acute injury damages tendon tissues causing tendonitis. Repetitive use...
According to the American Academy of Orthopaedic Surgeons, the Achilles tendon is the longest tendon in the human body and can withstand forces of more than 1,000 lbs. The most common injuries to the Achilles tendon are Achilles tendinitis and an...
The Achilles tendon is the long ligament that runs from the bottom of the heel to the calf. It is a weakness for many runners and athletes, just as it was for the Greek god Achilles who derived the weakness when his nurse held him tightly by the...
