The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The body contains three types of muscle tissue: (a) skeletal muscle, (b) smooth muscle, and (c) cardiac muscle. On the anterior and posterior views of the muscular system above, superficial muscles (those at the surface) are shown on the right side of the body while deep muscles (those underneath the superficial muscles) are shown on the left ...
The anterior chain, which comprises the antagonists of the posterior chain, refers to the group of skeletal muscles that lies on the front of the human body. This includes the biceps, the pectoralis major and pectoralis minor (chest) muscles, the abdominals, the obliques, the serratus anterior, and the quadriceps.
The linea alba is a white, fibrous band that is made of the bilateral rectus sheaths that join at the anterior midline of the body. These enclose the rectus abdominis muscles (a pair of long, linear muscles, commonly called the “sit-up” muscles) that originate at the pubic crest and pubic symphysis, and extend the length of the body’s trunk.
Different skeletal muscle types: A: fusiform. B: unipennate. C: bipennate. (PCS: physiological cross-section) Muscles may also be described by the direction that the muscle fibres run, in their muscle architecture. Fusiform muscles have fibres that run parallel to the length of the muscle, and are spindle-shaped. [19]
The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
A fascial compartment [1] is a section within the body that contains muscles and nerves and is surrounded by deep fascia.In the human body, the limbs can each be divided into two segments – the upper limb can be divided into the arm and the forearm and the sectional compartments of both of these – the fascial compartments of the arm and the fascial compartments of the forearm contain an ...
Green is the medial compartment (gracilis and adductor magnus), blue is the posterior (semimembrosus to biceps c. brevis) and red is the anterior (vastus lateralis to sartorius). The fascial compartments of thigh are the three fascial compartments that divide and contain the thigh muscles.
