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.
Probably the best-known region of the brain associated with motor control (movement) is the primary motor cortex. The primary motor cortex is located in the precentral gyrus, â¦ just anterior to the central sulcus. However, the pre-motor areas of the frontal lobe, as well as the cerebellum are also very involved with motor control.
