What is the Subclavius muscle? A short, three-sided muscle of the thoracic wall located below the clavicle is the subclavius muscle. It travels laterally from the first rib to insert on the middle third of the clavicle’s undersurface. The fundamental capability of the subclavius is to stabilize the clavicle during the action of the shoulder…
What are Rhomboid muscles? The rhomboid muscles are a group of muscles located in the upper back region, between the spine and the shoulder blades. They are named for their shape, which resembles a rhombus or diamond shape. Two bilateral, superficial muscles in the upper back are the rhomboids. They contain two practically comparative muscles…
What is Latissimus dorsi muscle? The muscle known as the latissimus dorsi (the lats muscle’ or ‘lats’) is the broadest in the human body. Except for the trapezius, it covers almost all of the muscles in the posterior trunk of the back. The latissimus dorsi muscle is a member of the superficial layer of the…
Muscles of the chest are referred to as “Pecs” muscles. These muscles are Pectoralis Major, Pectoralis minor, Serratus Anterior, and Subclavius. Chest muscles connect the front of the human chest with the bones of the upper arm and shoulder. The pectoral region has four muscles that create movements to the upper limbs or ribs. Pectoralis…
The shoulder muscles play a vital role in the complex mechanics of the shoulder joint. Shoulder girdle movements are supported and caused by the shoulder muscles. They link the appendicular skeleton of the upper limb to the axial skeleton of the trunk. Four of them are on the front of the shoulder, while the others…
Major list of Core muscles are the pelvic floor muscles, transverses abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) mainly the longissimus thoracis and Diaphragm. Minor core muscles list are the latissimus dorsi, gluteus maximus and trapezius. The core muscles have two main functions: List of Core muscles: Major List of CORE…
Introduction The erector spinae is a series of muscles that extend from the sacrum to the neck and is located within the back, which is the largest muscle group in the body. The muscles of this specific group are divided into three different sections, which are the iliocostalis, longissimus and spinalis, which all have different…
Introduction The trapezius muscle is a large, superficial muscle located in the upper back and neck region of the human body. It is one of the major muscles responsible for the movement and stability of the shoulder girdle. Its name originates from its trapezoid shape, with its broad base spanning the upper back and its…
Anatomy of Levator Scapulae Muscle The levator scapulae muscle are superficial extrinsic muscles of the back that primarily function to elevate the scapulae. Levator comes from the Latin levare, meaning “to raise.” Scapulae refer to the scapulas, or shoulder blades, possibly originating from the Greek “skaptein,” meaning “to dig.” In conjunction with other posterior axial-appendicular…
Introduction The abdominal muscles form the anterior and lateral abdominal wall and consist of the external abdominal obliques, the internal abdominal obliques, the rectus abdominis, and the transversus abdominis. Acting together these muscles form a firm wall that protects the viscera and they help to maintain erect posture. In addition the contraction of these muscles…
