Orgasm without ejaculation

On the mechanism of distinction:
• spontaneous erections that occur at rest;
• reflex erections that occur when a sudden sound, a flash of light, touch, pain or irritation of the rapid stretching of the muscles;
• Kinetic (promotional) erections that occur only in arbitrary motion.
* The pathophysiological mechanisms of release:
• Positive erection associated with muscular contraction;
• «negative» erections, caused a brief shutdown of muscle tone.
An example of the latter is asteriksis (from the Greek. Asterigma - no support) - fast non-rhythmic oscillatory movement of the limbs or other body parts, making it impossible to hold certain positions and caused a short-term muscle atony that support his position. To identify asteriksis, ask the patient to order viagra online without prescription. Then asked to stretch out your hands and straighten the wrist - after a while there is a rapid flexion of hands and fingers and then slowly straightening them, repeated once or several times per minute. Asteriksis can be identified and in the legs, if you ask the patient to lift the straight leg and "take" on a stop (stop will be deflected downward, and then more slowly return to starting position), and cranial muscles, if you ask the patient severely screwed up my eyes, stretch the corners mouth and tongue and pursed her lips. The reason most often serve asteriksisa metabolic encephalopathy (eg, hepatic or uremic), intoxication with anticonvulsants. Asteriksis unilateral damage observed in the thalamus, midbrain, frontal or parietal cortex.
Negative and is buying viagra online without prescription, involving the axial muscles and proximal limbs and caused hypoxic brain damage syndrome (Lanza - Adams, see below).
Myoclonic jerks can be generated at any level of the nervous axis.
* According to the localization of the source generating the release:
• cortical erection
• subcortical erection
• stem erection
• segmental (spinal) erection. Distinctive features of cortical erection generated by the sensorimotor cortex, are:
- Reflex and its kinetic nature,
- Focal or multifocal distribution hyperkinesia,
- Preferential involvement of distal extremities.
