The upright row is a weight training exercise performed by holding a weight with an overhand grip and lifting it straight up to the collarbone. This is a compound exercise that involves the trapezius, the deltoids and the biceps. The narrower the grip the more the trapezius muscles are exercised, as opposed to the deltoids.
The trapezius [4] is a large paired trapezoid-shaped surface muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae of the spine and laterally to the spine of the scapula. It moves the scapula and supports the arm. The trapezius has three functional parts: an upper (descending) part which supports the weight ...
Poor posture can cause rounded shoulders because of the muscle imbalance [12] and uneven weight distribution in our upper body. [13] Long periods of time spent in positions that put undue strain on the shoulders and neck may wear out some of the muscles while weakening others.
Secondary to serratus anterior palsy, a winged scapula is also caused by trapezius and rhomboid muscle palsy involving the accessory nerve and the dorsal scapular nerve, respectively. [ 1 ] Though the most common causes of a winged scapula is due to serratus anterior palsy, and less commonly trapezius and rhomboid palsy, there are still other ...
A muscle slip, the axillary arch, varying from 7 to 10 cm in length, and from 5 to 15 mm in breadth, occasionally springs from the upper edge of the latissimus dorsi about the middle of the posterior fold of the axilla, and crosses the axilla in front of the axillary vessels and nerves, to join the under surface of the tendon of the pectoralis ...
The American Academy of Orthopaedic Surgeons (AAOS) is an orthopedic organization. Founded at Northwestern University in 1933, as of 2015 AAOS had grown to include about 39,000 members. [1] The group provides education and practice management services for orthopedic surgeons and allied health professionals. It also lobbies and works on public ...
The trapezoid ligament is a ligament connecting the coracoid process of the scapula (the shoulder blade) to the trapezoid line of the clavicle (collarbone). It is an anterior and lateral fasciculus, and is broad, thin, and quadrilateral.
The trapezoid body or ventral acoustic stria is a structure in the pontine tegmentum formed by the crossing-over (decussation) of a portion of the efferent second-order fibers of the ventral cochlear nucleus (anterior cochlear nucleus).
