This reflex is elicited by lightly stroking or poking the superior and medial (inner) part of the thigh—regardless of the direction of stroke. [1] The normal response is an immediate contraction of the cremaster muscle that pulls up the testicle ipsilaterally (on the same side of the body). The reflex utilizes sensory and motor fibers from ...
Cremaster is an involuntary muscle, responsible for the cremasteric reflex; a protective and physiologic superficial reflex of the testicles. The reflex raises and lowers the testicles in order to keep them protected. Along with the dartos muscle of the scrotum, it regulates testicular temperature, thus aiding the process of spermatogenesis. [1]
The cremasteric reflex (elevation of the testicle in response to stroking the upper inner thigh) remains normal. [1] This is a useful sign to distinguish it from testicular torsion. If there is pain relieved by elevation of the testicle, this is called Prehn's sign, which is, however, non-specific and is not useful for diagnosis. [13]
In human anatomy, the groin, also known as the inguinal region or iliac region, [1] is the junctional area between the torso and the thigh. [2] The groin is at the front of the body on either side of the pubic tubercle , where the lower part of the abdominal wall meets the thigh.
At anatomy dinners around the country, doctors and chefs are working together to explain how the body works and how animals are turned into food. Heart, testicles and brain are on the menu at ...
Testicular pain, also known as scrotal pain, occurs when part or all of either one or both testicles hurts. Pain in the scrotum is also often included. Testicular pain may be of sudden onset or of long duration. [1] [2] Causes range from non serious muscular skeletal problems to emergency conditions such as Fournier gangrene and testicular ...
The genital branch of the genitofemoral nerve, also known as the external spermatic nerve in males, is a nerve in the abdomen that arises from the genitofemoral nerve.The genital branch supplies the cremaster muscle and anterior scrotal skin in males, and the skin of the mons pubis and labia majora in females.
However, the surface anatomy of the point is disputed. In a recent study, [ 8 ] it was found to be in a region between the mid-inguinal point (situated midway between the anterior superior iliac spine and the pubic symphysis ) and the midpoint of the inguinal ligament (i.e. midway between the anterior superior iliac spine and the pubic tubercle ).
