    A new type of the coracobrachialis muscle
    (Folia Morphologica, 2022) Zielinska, Nicol; Aragonés Maza, Paloma; Sañudo Tejero, José Ramón; Łabętowicz, P.; Shane Tubbs, R.; Olewnik, Lukasz
    The coracobrachialis muscle belongs to the anterior group of the brachial region. Its main functions are flexion and adduction at the glenohumeral joint. It is highly morphologically variable, especially in the number of bellies, place of origin or insertion, and its relationship to the musculocutaneous nerve. Accessory structures associated with the coracobrachialis muscle include the coracobrachialis brevis or coracobrachialis longus muscle. The present case describes a three-headed coracobrachialis muscle with two such additional structures. One of these has a tendinous origin connected to the periosteum and located on the surgical neck of the humerus. Its insertion is fused with the third head of the coracobrachialis muscle. The other has a proximal attachment fused with the capsule of the shoulder joint, and its distal attachment is fused with the third head of the coracobrachialis muscle in place of its connection with the short head of the biceps brachii. This could result in better stabilisation of the glenohumeral joint; on the other hand, it could limit operational access during treatment of subscapularis tears

    The relationship between additional heads of the quadriceps femoris, the vasti muscles, and the patellar ligament
    (BioMed Research International, 2022) Olewnik, Lukasz; Ruzik, Kacper; Szewczyk, Bartłomiej; Podgórski, Michal; Aragonés Maza, Paloma; Karauda, Piotr; Shane Tubbs, R; Sañudo Tejero, José Ramón; Bettencourt Pires, Maria; Polguj, Michal
    The quadriceps femoris consists of four muscles: the rectus femoris, vastus medialis, vastus intermedius, and vastus lateralis. However, the effect of additional quadriceps femoris heads on the vasti muscles and patellar ligaments is unknown. The aims of the present study are to determine the relationship between additional quadriceps femoris heads and the vasti muscles and patellar ligaments and to review the morphology of the vastus lateralis, vastus medialis, and vastus intermedius. Materials and Methods. One hundred and six lower limbs (34 male and 19 female cadavers) fixed in 10% formalin were examined. Results. On all lower extremities, the vastus lateralis consisted of superficial, intermediate, and deep layers. The vastus medialis, on the other hand, consisted of only the longus and obliquus layers. The quadriceps head had one or more supplementary heads in 106 dissected limbs from 68 cadavers (64.1%). The distal portion of the patella was wider in lower limbs without supplementary heads than in type IA but narrower than in type IIIA. In general, the distal portion of the patella was narrower in specimens with a supplementary head than in those without (19.03 SD 3.18 mm vs. 20.58 SD 2.95 mm, p = 0:03817). Other patellar ligament dimensions did not differ significantly. Conclusion. The quadriceps femoris muscle is characterized by high morphological variability. Occurrence of extra heads is at the level of 64.1%. The vastus lateralis consists of three parts (superficial, intermediate, and deep), and vastus medialis consists of two (longus and oblique).
