[A method of objective estimation of anal and bulbocavernosus reflexes in children]
Abstract:
The authors suggest a new method of detecting the anal and bulbocavernosus reflexes. It consists in stimulation of the reflexogenic area skin by electric current and in determination of the response according to pressure changes in the anal canal. The status of the sacral reflex arch is judged from the two objective magnitudes: current power in mA and pressure in kPa. The efficacy of the given research method is shown with special reference to 30 patients in whom the anal reflex is to be determined. The anal reflex is demonstrated to be less remarkable in children with incontinence of the intestinal contents as compared to those suffering from constipation.

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...
