slowly terminates motor neutrons in the brain and spinal cord. Motor neurons are an important part of the body’s neuromuscular system; the neuromuscular system is what aids our body’s movement. It is made up of the brain‚ muscles‚ and nerves. Upper motor neurons send messages from the brain to the spinal cord‚ while the lower motor neurons send messages from the spinal cord to our muscles. Over time the disease causes these motor neurons in the brain and spinal cord to shrink‚ and finally disappear‚

called Nervous Networks. Here a reconfigurable central network oscillator is utilized for autonomous and independent operation of components. Further it favors development of legged robos. The nervous technology provides (1) pulse delay circuits (neurons)‚ interconnected in closed loops‚ which generate square waves and (2) pulse neutralization circuits. The central sequencing network and limb circuits control the direction of the motor thereby the motion of their legs. The advantage is that the use

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.

Neuroscience: Neurotransmitters (small molecule and neuroactive)‚ storage release removal and disease. 1. The brain is made up of neurons that process and transmit information by electrochemical signaling. Neurotransmitters are endogenous chemicals which relay‚ amplify‚ and modulate signals between a neuron and another cell. Chemical messengers must fulfill four criteria to be considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of

Education & Sports Mr. April 13‚ 2015 What is the Neuromuscular System? According to research the neuromuscular system is to make the body move‚ a signal travels along neurons nerve cells from the brain to the spinal cord. There‚ "lower motor neurons" pass the message on to the muscles. The end of every lower motor neuron releases a chemical‚ which is received by receptors in the muscle tissue. Once enough of the chemical has been received‚ the muscle is able to move. Sometimes this process malfunctions
