An essential amino acid is one your body cannot make, so you have to get it from food or dietary supplements. Collagen is the most abundant protein in the body and is a key constituent of all connective tissues. Collagen provides the infrastructure of the musculoskeletal system, essential for mobility.The intake of collagen ensures the cohesion, elasticity and regeneration of skin, hair, tendon, cartilage, bones and joints.Collagen is a protein made up of amino-acids: glycine, proline, hydroxyproline, and arginine.The composition of collagen is considered unique given its high hydroxyproline content. If you lack the amino acids that combine to form collagen, your body's cells can't produce enough of it.ollagen provides the infrastructure of the musculoskeletal system, essential for mobility.

A ganglion cell (sometimes called a gangliocyte) is a type of neuron located in the retina of the eye that receives visual information from photoreceptors via various intermediate cells such as bipolar cells, amacrine cells, and horizontal cells.
A neuron (also known as a neurone or nerve cell) is a cell that carries electrical impulses. Neurons are the basic units of the nervous system and its most important part is the brain. Every neuron is made of a cell body (also called a soma), dendrites and an axon. Dendrites and axons are nerve fibres. There are about 86 billion neurons in the human brain, which comprises roughly 10% of all brain cells.
