Neurons are the structural and functional units of nervous tissue. Each neuron has a long axon, a metabolic center (soma) and short dendrites. Neurons and neuroglia are the major cell types that together constitute the nervous tissue.
The brain is an organ made of nervous tissues and is a part of the central nervous system. The central and peripheral nervous systems together make the nervous system of the human body.
The nervous system along with many other organ systems such as the digestive system, respiratory system, cardiovascular system, etc. together make the human body.
The molecule known as coenzyme A plays a key role in cell metabolism by regulating the actions of nitric oxide. Coenzyme A sets into motion a process known as protein nitrosylation, which unleashes nitric oxide to alter the shape and function of proteins within cells to modify cell behavior.
