Biomechanical evolutionary advantage of flexor pollicis longus accessory head and topographical association with neurovascular structures.

The human upper limb has undergone various evolutionary myologic changes, accompanied by corresponding modifications in the anatomical course of neurovascular structures. In this study, we aimed to elucidate the emergence of the accessory head of the flexor pollicis longus (AHFPL) muscle as a beneficial biomechanical evolutionary development and its topographical relationship with adjacent neurovascular structures. In this pursuit to understand this phenomenon, dissections were conducted on sixty-two upper limbs from thirty-one cadavers.

Bilateral Symmetric Absence of Lumbricals of the Foot: A Rare Case Report.

Variations of the lumbricals of the foot are not common, unlike the lumbricals of the hand. Few cases of unilateral absence of lumbricals of the foot have been reported. There have been far fewer cases of bilateral asymmetric absence of the lumbricals of the foot reported.

Bilateral higher carotid termination with rare anomalous emergence of ventral branches of the external carotid arteries: A cadaver study.

The common carotid artery bifurcates into two terminal branches-the external and internal carotid arteries. The head, neck, and face regions principally get their blood supply from the external carotid artery and its branches. Some previous articles have mentioned the abnormal pattern of the external carotid artery branching and its variable origin.

The deleterious impact of a non-synonymous SNP on protein structure and function is apparent in hypertension.

Essential hypertension (EH) is a significant health issue around the globe. The indifferent therapy regimen suggests varied physiological functions due to the lifestyle and genetic presentations of an individual. The endothelial nitric oxide synthase (NOS3) gene is a crucial vascular system marker in EH that contributes significantly to the phenotype.

Estrogen receptor α and β gene polymorphism in relation to bone mineral density and lipid profile in Northeast Indian women.

Estrogen regulates bone homeostasis and has a cardio-protective effect. Its physiological functions are mediated through receptors (ER) whose expression can be regulated by presence or absence of polymorphisms. However, the association between ER polymorphisms and BMD as well as lipids are inconsistent.
