organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves that branch from the cervical‚ thoracic‚ lumbar‚ and sacral regions of the spinal cord are called the peripheral nerves. The peripheral nervous system consists of sensory neurons running from stimulus receptors that inform the Central Nervous

EMG is an obligatory investigation in motor neurone disease to demonstrate the widespread denervation and fasciculation required for secure diagnosis. II.

Patient’s own stem cells can be used in what are called autologous transplant. In comparison between allogeneic peripheral blood stem cell transplantation (PBSCT) to bone marrow transplantation (BMT)‚ PBSCT shows faster engraftment‚ more GVHD‚ a decrease in relapse and improved disease-free

increased diameter of blood vessels and increased volume allows for less of the blood to come in contact with the walls of the vessels. So a larger volume of blood is allowed to pass through a vessel without obstruction‚ characterizing a decrease in peripheral resistance. This increased blood flow is explained by an immediate increase in heart rate‚ which is what allows for more blood to pass through the vessels. The decreased blood pressure‚ caused by an increased vessel diameter‚ is detected by baroreceptors

When arteries narrow‚ peripheral resistance rises. When they widen‚ peripheral resistance drops. More cardiac output and greater peripheral resistance result in higher blood pressure. During vigorous exercise‚ your systolic blood pressure rises because your heart must work harder to pump more blood with each contraction to keep your

I have been called by a junior nurse from maternity ward to set a peripheral line for her patient under her care. As a junior nurse she is not confident to set a line by looking at patient condition that is very weak. Without delaying‚ I went to visit that particular patient to help my nurse.
