The muscle diagram on InnerBody.com shows the entire human body with a number of specific muscles marked by green dots. The two-dimensional interactive map is divided into a number of muscle areas for closer examination. Areas include the head and neck, chest and upper back, leg and foot, and arm and hand.
Muscle Anatomy: The scale and arrangement of muscles goes from muscle organ, fascicle, fiber, myofibril, to myofilaments within repeating sarcomere units (Fig. 1) 1. A muscle organ = whole muscle group, made of a bunch of fascicles (ex. biceps brachii).2. muscle fascicle = bundle of muscle muscle fibers. 3. muscle fiber = a single muscle cell, which is innervated by a motor neuron in the neuromuscular junction (the junction between a motor neuron and muscle fiber).. muscle fascicle = bundle of muscle muscle fibers. 3. muscle fiber = a single muscle cell, which is innervated by a motor neuron in the neuromuscular junction (the junction between a motor neuron and muscle fiber).
