If you file for Chapter 7 relief, but you have a certain amount of disposable income, the bankruptcy court could convert your Chapter 7 case to a Chapter 13, thus changing your plan to be free from most debts within four to six months, to a plan requiring you to repay your debts over the course of three to five years.
Definition of Motor Unit. A motor unit consists of one somatic efferent (motor) neuron and all of the muscle fibers (cells) that it innervates. In the figure to the right, two motor units are illustrated diagrammatically.Notice that after an efferent axon enters the muscle, it branches and forms synapses with a number of muscle fibers.hus, each motor unit is either relaxed or each presynaptic action potential causes an action potential in all of the muscle fibers of the motor unit, causing them all to contract at once. In the whole muscle, contractions of different strengths necessarily are created by activating different numbers of motor units.
A motor neuron (or motoneuron) is a nerve cell (neuron) whose cell body is located in the spinal cord and whose fiber (axon) projects outside the spinal cord to directly or indirectly control effector organs, mainly muscles and glands.ypes of motor neurons are alpha motor neurons, beta motor neurons, and gamma motor neurons. There are upper motor neurons and lower motor neurons, with the cell type described above being a lower motor neuron.
