Q 1 what is cremastric reflex and how to elicit - show on a patient ??
A 1 The cremasteric reflex is a superficial (i.e., close to the skin’s surface) reflex observed in human males.
1 This reflex is elicited by lightly stroking or poking the superior and medial (inner) part of the thigh - regardless of the direction of stroke.
2 The normal response is an immediate contraction of the cremaster muscle that pulls up the testis ipsilaterally (on the same side of the body) VV IMP - SAME SIDE ELEVATION
3 The reflex utilizes sensory and motor fibers from two different nerves.
4 When the inner thigh is stroked, sensory fibers of the ilioinguinal nerve are stimulated.
5 These activate the motor fibers of the genital branch of the genitofemoral nerve which causes the cremaster muscle to contract and elevate the testis.
