The endocrine system is a system of ductless glands that secretes hormones directly into the circulatory system to be carried long distances to other target organs regulating key body and organ functions. For example, the pineal gland, located at the base of the brain, secretes the hormone melatonin, responsible for regulating sleep patterns. Endocrine glands are typically well vascularized and the cells comprising the tissue are typically rich in intracellular vacuoles or granules that store hormones prior to release.
Endocrine signaling is typically slow to initiate but is prolonged in response; this provides a counterpoint to the more rapid and short-lived nervous system signals. The endocrine system is in contrast to the exocrine system, which features ducted glands that secrete substances onto an epithelial surface; for example, a sweat gland.
The major endocrine glands include the pituitary, pineal, ovaries, testes, thyroid, hypothalamus and adrenal glands, additionally other tissues such as the kidney and liver also display secondary adrenal functions. Endocrine glands of the head and neck : The endocrine systems found in the head and neck include the hypothalamus, pineal, pituitary and thyroid glands.
The nervous system and endocrine system both use chemical messengers to signal cells, but each has a different transmission speed. The body must maintain a constant internal environment, through a process termed homeostasis, while also being able to respond and adapt to external events.
The nervous and endocrine systems both work to bring about this adaptation, but their response patterns are different. The nervous system and the endocrine system use chemical messengers to signal cells, but the speed at which these messages are transmitted and the length of their effects differs. The nervous system responds rapidly to stimuli by sending electrical action potentials along neurons, which in turn transmit these action potentials to their target cells using neurotransmitters, the chemical messenger of the nervous system.
The response to stimuli by the nervous system is near instantaneous, although the effects are often short lived. Controls immunity and metabolism. Controls metabolism. Testes, occasionally from ovaries and adrenal gland. Regulates male reproductive and sexual development. Regulates female reproductive and sexual development. Controls blood sugar and storage of fat. Controls blood sugar. Nervous System.
Endocrine System. In the nervous system, electrical impulses carry the messages to different organs of the body. The endocrine system uses hormones, chemical signals, to carry commands to the destined organs and cells. Nerve or electrical impulses transmit through neurons. Hormones travel through bloodstreams. Brains and spinal cords, the two major body parts are used in this regulatory system. Several organs like testes, ovaries, etc. The nervous system can control voluntary as well as involuntary activities.
Mar 21, Explanation: While both systems control parts of body by transmitting impulses there are many differences between nervous system and endocrine system.
Hormones are transported chemically through blood, nervous impulses are transported electrochemically through nerve fibres. Hormones affect different organs of the body and has a widespread effect, while nervous impulses afeect only a particular part of the body. Hormonal effect is long lasting whereas nervous effect is short lived. Hormones can bring about a metabolic change but nervous impulse impulses cannot bring about a metabolic change.
