Skull Sutures Quiz . Match. V. There is INTERTUBERCLE SULCUS (groove like structure) which separates lesser tubercle from greater tubercle. The surgical neck is a common site for fractures (hence its name), while fractures of the anatomical neck are rare.. The anatomical neck of the humerus is obliquely directed, forming an obtuse angle with the body of the humerus.It represents the fused epiphyseal plate. It connects the scapula and the two bones of the lower arm, the radius and ulna. 1 Upper Extremity.—The upper extremity consists of a large rounded head joined to the body by a constricted portion called the neck, and two eminences, the greater and lesser tubercles. ; Anatomical neck is present at the junction of head and rest of the upper end. rounded side. STUDY. It articulates with the scapula here.This is the shoulder joint, the glenohumeral joint.. Adachi summarized the literature (up to 1828) and found 12 authors (not including Gruber) had studied 9620 humeri and identified supracondylar processes in 78 or 0.8% of arms. The humerus is a long bone consisting of three parts; the head which is directed upwards and medially, the shaft, and the lower end. Spell.
