It is marked by elevated blood glucose levels.
Type I diabetes mellitus (insulin-dependent) is an autoimmune disorder in which the immune system destroys pancreatic beta cells.
Type II diabetes mellitus (non-insulin-dependent) involves insulin deficiency or reduced response of target cells due to change in insulin receptors.
The endocrine and nervous systems act individually and together in regulating animal physiology
Signals from the nervous system initiate and regulate endocrine signals.
Coordination of Endocrine and Nervous Systems in Invertebrates
In insects, molting and development are controlled by a combination of hormones:
A brain hormone stimulates release of ecdysone from the prothoracic glands
Juvenile hormone promotes retention of larval characteristics
Ecdysone promotes molting (in the presence of juvenile hormone) and development (in the absence of juvenile hormone) of adult characteristics
Hormonal regulation of insect development
Coordination of Endocrine and Nervous Systems in Vertebrates
The hypothalamus receives information from the nervous system and initiates responses through the endocrine system.
Attached to the hypothalamus is the pituitary gland composed of the posterior pituitary and anterior pituitary.
The posterior pituitary stores and secretes hormones that are made in the hypothalamus
The anterior pituitary makes and releases hormones under regulation of the hypothalamus
Endocrine glands in the human brain
Hypothalamus = brain
Oxytocin induces uterine contractions and the release of milk
Suckling sends a message to the hypothalamus via the nervous system to release oxytocin, which further stimulates the milk glands
