What directly influences the function of the cell?

The endocrine system has a lot to do with cell influence, both directly and indirectly.  The endocrine system is a system of organs in the body that produce chemicals called hormones that influence specific target tissues in the body.  Growth hormone, sometimes abbreviated GH, for example, is secreted by the pituitary gland and is responsible for the manufacture and maintenance of body tissues related to body growth.  It promotes healthy bone structure and maintenance in the skeletal system, as well as the production and maintenance of proteins for the muscular system.  The endocrine system works with a negative feedback style of stimulus.  For example, the pituitary gland, also called the master gland of the endocrine system, may detect low blood sugar levels within the body.  It directs the production of a hormone called glucagon, which acts upon the liver to release stored sugar into the blood stream.
