Morphological Variability of the Thigh Muscle Traps in an Ultrasound That Awaits Clinicians.

Muscles and their tendons present a considerable diversity of morphological variations. The aim of this study was to explore variants of muscles and tendons from compartments of the thigh and to raise awareness about potential problems during ultrasound examination. This comprehensive review of the literature was created on the basis of scientific articles sourced from PubMed.

Radiological and anatomical evaluation of the internal venous system in the context of access to the third ventricle - proposal of a new classification.

Background: The internal venous system of the brain is a crucial anatomical landmark during accesses to the third ventricle through the foramen of Monro. Many classifications based on radiological assessment of the system have been developed, but they tend to be descriptive and do not highlight favorable anatomical variants. The aim of our study was to create a system based on morphometric measurements to facilitate preoperative decision-making regarding access to third ventricle tumors.

An unusual variant of an accessory thoracic muscle.

Background: The anterior thoracic wall musculature presents significant morphological variability. The current literature describes a few accessory thoracic muscles (ATMs) and discusses possible clinical implications. The dissection report describes an unusual ATM variant.

Coracobrachialis muscle variants in human fetuses.

Purpose: The current cadaveric study on human fetuses demonstrates the coracobrachialis muscle variability. It further analyzes the embryological and phylogenetic background as well as the coracobrachialis muscle variability in adults.

Materials: Classical (gross anatomy) dissection was performed on 140 (34 male and 36 female) upper limbs of human fetuses, 10 % formalin-fixed.

An accessory slip of the fibularis tertius to the extensor digitorum longus - an unreported variant.

The fibularis tertius (FT) is one of three muscles which constitute the anterior compartment of the leg. The anatomical variants of this muscle usually pertain to its origins, number of final tendons or points and shapes of insertions. In this case, it had an additional slip (AS) which originated from the same area as the main muscle belly and after descending along the extensor digitorum longus (EDL) it fused with one of its main tendons.
