The neurons of the heart are not directly controlled by the human body’s central or peripheral nervous systems. Even without stimulation of the nerves‚ the heart will continue to beat at a steady rate (Wibbels & Vickery 2007). That

Our spinal cord extends several types of nerve fibers from the brain acts like a switching and relay terminal for the peripheral nervous system as is stated in Mosby’s Dictionary. The 12 pairs of cranial nerves emerge directly from the brain Sensory nerves and motor nerves of the peripheral system leave the spinal cord separately between the vertebrae but unite to form 31 pairs of spinal nerves containing sensory fibers and motor fibers.

Introduction In order to understand the causes of autism‚ biologically‚ environmentally‚ cognitively‚ one must understand what autism truly is. According to the American Psychiatric Association‚ autism spectrum disorder is defined by impairment in social interaction and communication skills‚ as well as an occurrence of repetitive behavior along with a need for a routine (APA‚ 2000). The American child psychologist Leo Kanner first described the condition in 1943 (Funk & Wagnalls‚ 2014). It is

Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system‚ a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.
