This contraction cycle is repeated as long as free calcium is available to bind the troponin and ATP is available to provide the energy. The signal to stop contraction is the absence of the nerve impulse at the neuromuscular junction. When this occurs, an energy requiring calcium pump located within the sarcoplasmic reticulum begins to move the calcium back into the sarcoplasmic reticulum. This removal o...

In the brain and the brain stem there are special cells called neurons. Neurons release a number of chemicals that are sent to various receptors. The receptors interpret chemical signals and use them to make you move, see, hear, learn, etc. These neurons are also responsible for such behaviors as obsessive-compulsive behavior and insomnia. The cells that are direct...

Neuro Transmission Positive Charge
488 wordsneurotransmitters play a central and critical role in our psychological existence, identity, and experience of the world Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the cell membrane causes...

Ability To Choose Quantum Physics
1,907 wordsThe debate between free will and determinism stems from the apparent conflict between the universal rule of causality found in nature and the apparent ability of men to choose between multiple courses of action in order to lead to the most desirable outcome. Inorganic matter such as chairs, stones, and planets, blindly follows whatever forces affects it, and non-human organisms act for their survival alone, but human beings seem to be an exception to natures rule by their unique ability to ponde...

1,508 wordsThe only multi-cellular animals without a nervous system are sponges. They do not have any nerve cells or sensory cells. Despite this, touch or pressure to the outside of a sponge will cause a local contraction of its body. Cnidarians The jellyfish and most all other forms of cnidarians, such as the hydra and sea anemone, are characterized by a nerve net. A nerve net is a series of interconnected nerve cells that conduct impulses around the jellyfish's entire body. The strength of the jellyfish'...

Plays A Major Role Parkinsons Disease
382 wordsAn integral component Dopamine Dopamine An integral component of the Central Nervous System is dopamine. Dopamine is a neurotransmitter which plays a major role in carrying out two activities of the CNS. Dopamine assists in controlling movement, and it is strongly linked with behaviors based on emotion. Neurons from an area of the brain, substantia nigra, which connects to the corpora strata is the area from where dopamine is released. This pathway is involved in movement control and the musculo...

Dopamine Making Neurons Substantia Nigra Spider
367 wordsInsects have sensors (force-sensitive organs) concentrated in areas near joints, tips of the legs, and near exoskeletal sites attached to muscle tendons. These sensors act as strain gauges to detect compression of the exoskeleton. Using this information, insects recognize environments, regulate walking movements, and astonishingly remember stepping patterns and location. Through memory experiments, scientists see that a spider memorizes its own previous walking movements to backtrack to a fly. A...
