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.
This process is coordinated by the sensory neurons, which are situated along the nerve conducting pathway. Motor Nerves. Motor nerves connect the central nervous system and muscles in the body, through the motor neurons, where the motor nerves are originated. The cell body for each nerve lies in the spinal cord.Each motor nerve connects a specific muscle in the body, and it carries impulses, which causes the muscle to contract.his process is coordinated by the sensory neurons, which are situated along the nerve conducting pathway.
