The third section describes the development of motoneurons' passive and active electrophysiological properties. This section also defines the major terms one uses in describing how a neuron functions electrophysiologically. The electrophysiological aspects of a neuron is critical to understanding how it ...

THE NERVE fibers from the motor cells of the anterior horns of the spinal cord arborize several times in their distal passage and finally innervate a large number of muscle fibers. A group of muscle fibers thus innervated is generally termed a motor unit (motoneuron) and probably constitutes ...

A neuron (nerve cell) is the functional unit of the nervous system. They receive and transmit neural impulses. Meaning that, neurons receive, process and integrate information from all regions of the body and send instructions on how body tissues are to respond to environmental and internal event...
Cerebrum, the largest and uppermost portion of the brain. The cerebrum consists of the cerebral hemispheres and accounts for two-thirds of the total weight of the brain. The cerebral cortex is responsible for integrating sensory impulses, directing motor
