Pectoralis minor syndrome (PMS) is a condition related to thoracic outlet syndrome (TOS) that results from the pectoralis minor muscle being too tight. [1] PMS results from the brachial plexus being compressed under the pectoralis minor [2] while TOS involves compression of the bundle above the clavicle. In most patients, the nerves are ...
Although the cause of RSP is multifactorial, two major contributors to RSP are the tightness of the pectoralis minor muscle and the weakening of lower trapezius muscle. [34] As the only scapulothoracic muscle anteriorly originating and inserting to the scapula , the pectoralis minor ’s function in favoring the internal and downward rotation ...
Pectoralis minor muscle (/ ˌ p ɛ k t ə ˈ r æ l ɪ s ˈ m aɪ n ər /) is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major in the human body. It arises from ribs III-V; it inserts onto the coracoid process of the scapula. It is innervated by the medial pectoral nerve.
Pectoral muscles (colloquially referred to as "pecs") are the muscles that connect the front of the human chest with the bones of the upper arm and shoulder. This region contains four muscles that provide movements to the upper limbs or ribs. Deep muscles of the chest, including pectoralis minor, serratus anterior, and subclavius (Gray 1918)
Symptoms: Pain, dysthesias, paresthesias, and hyperesthesia on the anterolateral thigh [2] Causes: Anything that compresses the lateral femoral cutaneous nerve, such as tight fitting clothes at the waist and injuries. [3] Risk factors: Obesity, pregnancy, diabetes, middle-age [3] Diagnostic method: Clinical examination and patient history [2]
Serratus anterior forms part of the latter group together with rhomboid major, rhomboid minor, levator scapulae, and trapezius. The trapezius evolved separately, but the other three muscles in this group evolved from the first eight or ten ribs and the transverse processes of the cervical vertebrae (homologous to the ribs).
Parsonage–Turner syndrome, also known as acute brachial neuropathy, neuralgic amyotrophy and abbreviated PTS, is a syndrome of unknown cause; although many specific risk factors have been identified (such as; post-operative, post-infectious, post-traumatic or post-vaccination). [4]
The axillary lymph nodes are arranged in six groups: [2] Anterior (pectoral) group: Lying along the lower border of the pectoralis minor behind the pectoralis major, these nodes receive lymph vessels from the lateral quadrants of the breast and superficial vessels from the anterolateral abdominal wall above the level of the umbilicus.
