Avoid These Cash Draining Start-up Mistakes. I'm a firm believer that even a tough economy provides rich opportunities for start-ups to innovate and thrive. In fact, more than a few ventures that were launched during recent downturns are now household names. But in today's uncertain business climate, when credit is tight and stretching your start-up dollars is the smart way to go, it's critical that you avoid cash-draining mistakes.
A neuron consists of two major parts: Axons and dendrites are bundled together into what are called nerves. These nerves send signals between the brain, spinal cord, and other body organs via nerve impulses. Nerve impulses are received at the neuronal dendrites and are carried along the axon to the terminal branches.
An action potential, which is the nerve impulse, occurs when a threshold is reached. Upon stimulation, the sodium gates open, Na+ flows into the axon, and the action potential swings up from -65mV to +40 mV.. The axon of a neuron conducts nerve impulses away from the cell body. Neurons that conduct messages from a sense organ to the central nervous system are called sensory, or afferent neurons. Those neurons that conduct an impulse from the CNS to a muscle or gland are called. motor, or efferent, neurons.
