the term “Dark Ages”. One of the most lasting documents that still impacts certain societies today was written in the year 1215. This document is known as the Magna Carta. The term Magna Carta is Latin for the “Great Charter”. Signed by King John on an open field in Runnymeade‚ under the pressure of the barons of Medieval England‚ the Magna Carta was the first document to list the rights of citizens. This document‚ although not successful at first‚ became the basis for England’s common law system

They are part of the class Crustacea and are related to lobsters‚ crabs‚ shrimp‚ and daphnia (water fleas). Crustaceans are also part of a larger group‚ Arthropoda (jointed-legged animals). All arthropods have a trunk divided into segments‚ a tough outer cuticle‚ and limbs that are flexible joints. Some behavior traits include rolling into

3 and 2.4. Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. <Insert Response Here> The communication process of neurons in the brain occurs through an electrochemical process. Neurons pass neurotransmitters through the dendrites‚ which are attached to the ends of each neuron and receive messages from neighboring neurons. The chemical messages that

gets too close to a candle. Their nervous system sends the stimulus to the brain‚ which tells the finger to back away from the flame. However‚ the synapses wouldn’t happen without neurotransmitters. These are chemicals that flow through neurons‚ which indicate what should be done next. There are two types of neurotransmitters: excitatory and inhibitory. The excitatory ones commands the neurons to work quickly; the

called neurotransmitters provide this role. As an electrical impulse travels down the extension of the cell‚ called the axon and arrives at its terminal‚ it triggers vesicles containing a neurotransmitter to move toward the terminal membrane. The vesicles fuse with the terminal membrane to release their contents. Once inside the synaptic cleft‚ the space between the two neurons‚ the neurotransmitter can bind to receptors on the membrane of a bordering neuron. Chemically‚ neurotransmitters are relatively

The electrical activity in a presynaptic neuron occurring at the chemical synapses causes the release of a chemical messenger called a neurotransmitter‚ which binds to neurotransmitter receptors on a postsynaptic neuron. Neurotransmitters are the chemical messengers that

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.
