Unilateral Absence of the Latissimus Dorsi: A Report of a Rare Case.

The latissimus dorsi is the largest muscle in the human body, located in the lower posterior thorax, and it contributes to motion in the upper extremity and provides assistance in respiration. This case report describes a rare occurrence of a unilateral absence of the latissimus dorsi accompanied by contralateral scoliosis in a 73-year-old female cadaver. The absence of the muscle along with the absence of the thoracodorsal nerve and branches of the subscapular and axillary arteries was identified during a standard dissection course.

Effects of the Presence Rate of the Palmaris Longus Tendon on Wrist Proprioception and Grip Strength.

Introduction: The palmaris longus muscle displays a great variation in terms of incidence and shape. This study has documented the incidence ratio of this muscle among the students at Bolu Abant İzzet Baysal University, Faculty of Medicine, and has revealed the effects of its presence on wrist proprioception and grip strength.

Methods: A total of 101 students between the ages of 18 and 25 were included in the study.
