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.
preganglionic neuron. A neuron of the autonomic nervous system whose cell body lies in the central nervous system and whose axon terminates in a peripheral ganglion, synapsing with postganglionic neurons.he axon conducts the impulses to the dendrite of another neuron or to an effector organ that is thereby stimulated to action. Many processes are covered with a layer of lipid material called the myelin sheath. Peripheral nerve fibers have a thin outer covering called neurilemma.
