In biochemistry, aligand is a substance that forms a complex with a biomolecule to serve abiological purpose. In protein-ligandbinding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.
Receptor mediated endocytosis is an endocytotic mechanism in which specific molecules are ingested into the cell. The specificity results from a receptor-ligand interaction. Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the cell. An endocytotic process occurs and the ligand is ingested.
A very well studied example of receptor mediated endocytosis involves the metabolism of cholesterol.

Bladder spinal reflex is the mechanism so you can
consciously void urine. There are receptors in the bladder that senses the
amount of urine collected. These are responsible for that ‘voiding urge’. The
higher the amount of urine collected, the greater the intensity of the signals.
Finally, when you get to the bathroom,
another set of nerves lets you consciously urinate so you can select which bathroom
stall is nice for peeing. Diabetes mellitus can damage nerves in the spinal
cord, including those involved in functioning of the bladder. Damage to the nerves
in the bladder spinal reflex arc is suspected if the patient suffers from
urinary retention – where the patient can consciously void urine but cannot
feel if the bladder is full.
No they do not have defined nucleus
A topographic map I believe would do great.
