During standard anatomical dissection of right upper limb, an variant muscle was found. It originated from the fascia covering the long head of biceps brachii and from the tendon of pectoralis major muscle. It also connected to the brachial fascia. It also demonstrated a long thin tendon which was distally attached to the medial epicondyle of humerus. Knowledge about the morphological variations in this region is clinically important because of their direct correlation with neurovascular structures, which may lead to pathologies such as tingling, muscle weakness, paresthesia, and loss of sensation.<\/jats:p>","DOI":"10.1007\/s00276-023-03240-6","type":"journal-article","created":{"date-parts":[[2023,9,21]],"date-time":"2023-09-21T15:02:20Z","timestamp":1695308540000},"page":"1493-1496","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A very rare case of a thoracobrachialis muscle"],"prefix":"10.1007","volume":"45","author":[{"given":"Nicol","family":"Zielinska","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Karauda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"W\u0119giel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bart\u0142omiej","family":"Szewczyk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0141ukasz","family":"Olewnik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,9,21]]},"reference":[{"key":"3240_CR1","volume-title":"Compendium of human anatomic variations","author":"RA Bergman","year":"1988","unstructured":"Bergman RA, Thompson SA, Afifi AK, Saadeh FA (1988) Compendium of human anatomic variations.
