The Muscular System: Contraction of Motor Units 1. Define a motor neuron:_____A single nerve cell that branches from the brain or the spinal cord to a muscle or a gland. 2. Define a motor unit: ___A motor neuron and all of the muscle fibers it stimulates. 3. The synapse between a motor neuron and the muscle it innervates is called a ____neuromuscular junction_______. 4. The stimulation of additional motor units will increase the strength of the contraction. This process is called

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture

Elizabeth Knox March 10‚ 2014 How can Lei apply the four step control process outlined in the text to address the problem of misreporting hours? Solution: A Control system has four control steps and they are; Setting performance standards‚ Measuring performance‚ Comparing performance against the standards and determining deviations‚ Taking action to correct problems and reinforce successes. Lei can apply all the four control process in the following ways: Setting performance standards:

An Open Mind to an Open System AN OPEN MIND TO AN OPEN SYSTEM The Open System Theory was initially developed by Ludwig von Bertanlanffy (1956)‚ a biologist‚ but it was immediately applicable across all disciplines. It defines the concept of a system‚ where "all systems are characterized by an assemblage or combination of parts whose relations make them interdependent". As one moves from mechanical to organic and social systems‚ the interactions between parts in the system become more complex and

because our nervous system encodes messages. German physiologist Johannes Muller in his doctrine of specific nerve energies described a kind of code which is anatomical. In his doctrine‚ Muller explains that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways that lead to different areas of the brain. For example‚ when the ear receives signals‚ these signals cause impulses to travel along the auditory nerve to the auditory cortex. And signals

Family Systems Theory This theory emerged from General Systems Theory by scholars who found it had many applications to families and other social systems. Any system is defined as a bounded set of interrelated elements exhibiting coherent behavior as a trait. (Constantine‚ 1986). Another definition is an assemblage of objects related to each other by some regular interaction or interdependence (Webster). Families are considered systems because they are made up of interrelated elements or objectives
