Carbon contributes an electron, and Hydrogen contributes an electron. The sharing of a single electron pair is termed a single bond. When two pairs of electrons are shared, a double bond results, as in carbon dioxide.
Elements of nervous system involved in motor coordinationEdit. The red nucleus is mainly involved in motor coordination of the muscles of the shoulder and upper arm, but it has some control over the lower arm and hand as well.
In addition, you must remember that the planning/programming associated with motor speech is thought by many to occur in Broca's area on the third frontal convolution, although a recent study has found that the Island of Reil was involved in 25 stroke patients who had a disorder involving the motor planning of speech (muscle movements) (Dronkers, 1996).
