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.
Impaired Motor Coordination in Crâ/â Mice. The general behavior of â6-week-old calretinin-deficient (Crâ/â) and wild-type (Cr+/+) mice previously analyzed in a series of tests was not different (19). Motor coordination was tested on the runway, the horizontal stationary rod, and the wheel running test.
