Neural control of erection.
Penile erection is a vascular event controlled by the autonomic nervous system. The spinal cord contains the autonomic preganglionic neurons that innervate the penile erectile tissue and the pudendal motoneurons that innervate the perineal striated muscles. Sympathetic pathways are anti-erectile, sacral parasympathetic pathways are pro-erectile, and contraction of the perineal striated muscles ...
متن کاملDual biochemical oscillators may control cellular reversals in Myxococcus xanthus.
Myxococcus xanthus is a Gram-negative, soil-dwelling bacterium that glides on surfaces, reversing direction approximately once every 6 min. Motility in M. xanthus is governed by the Che-like Frz pathway and the Ras-like Mgl pathway, which together cause the cell to oscillate back and forth. Previously, Igoshin et al. (2004) suggested that the cellular oscillations are caused by cyclic changes i...
متن کاملPathway Analyst—automating Biochemical Pathway Prediction
Pathways are crucial to our understanding of biology. The speed at which new organisms are being sequenced is outstripping our ability to experimentally determine their biochemical pathway information. In recent years several initiatives have been successful in automating the annotations of individual proteins in these organisms, either experimentally or by prediction. However, to leverage the ...
متن کاملPenile Erection
Hemodynamic Aspects Penile erection and detumescence are primari ly controlled by hemodynamic events. Increased arterial inflow appears to be of primary importance; the contribution of increased venous resistance to the production of penile erection remains controversial. Furthermore, our understanding of precise anatomic details ( including “shunts”) and the neural control of vascular events i...
متن کاملRole of the brain in the control of erection.
In contrast to the spinal control of erection, relatively little is known about the brain control. In the present review, we have outlined the role of brain structures involved in penile erection and provided a synopsis on the brain circuit of erection. Findings from both animal and human studies are discussed. Evidence suggests that the most important structures are the frontal lobe, cingulate...
