A tendon is made of dense regular connective tissue, whose main cellular components are special fibroblasts called tendon cells (tenocytes). [3] Tendon cells synthesize the tendon's extracellular matrix, which abounds with densely-packed collagen fibers. The collagen fibers run parallel to each other and are grouped into fascicles.
In a pennate muscle, aponeuroses run along each side of the muscle and attach to the tendon. The fascicles attach to the aponeuroses and form an angle (the pennation angle) to the load axis of the muscle. If all the fascicles are on the same side of the tendon, the pennate muscle is called unipennate (Fig. 1A).
The fibers in convergent, or triangular muscles converge at one end (typically at a tendon) and spread over a broad area at the other end in a fan-shape. [3] [6] Convergent muscles, such as the pectoralis major in humans, have a weaker pull on the attachment site compared to other parallel fibers due to their broad nature. These muscles are ...
The second Friday of the new year is "quitter's day"—but there are ways to make your fitness resolutions stick.
Analysis of the jaws and skull of the supposed human ancestors show that they had larger, stronger jaw muscles attached to the skull which would be expected with a diet rich in fruit and plants. The back set of molars were much larger for this reason also.

"Everything in the body is connected: muscles, ligaments, tendons and fascia," explains De Leon."If there is a 'weak link,' compensation, imbalance and injury are prone to happen.
Progressive overload not only stimulates muscle hypertrophy, but it also stimulates the development of stronger and denser bones, ligaments, tendons and cartilage. [5] Progressive overload also incrementally increases blood flow to regions of the body exercised and stimulates more responsive nerve connections between the brain and the muscles ...
