what is the endocrine system
is made of organs called glands that produce different hormones
Which system does the endocrine system work with
They work with the nervous system especially the automatic system to control and adjust functions
What are the glands in the brain
Hypothalamus and the pituitary glands
Where is the hypothalamus and the pituitary gland found
there found in the diencephalon
What is the hypothalamus
The hypothalamus secrets hormones that regulate Body temperature, Blood pressure, Sleep and many more
How does the hypothalamus perform
by directly influencing the autonomic nervous system or by managing hormones. Some hormones that is stored elsewhere send signals to the pituitary glands to either relieve hormones or signal another hormone
What are the five types of hormones in the hypothalamus
Thyrotropin releasing hormone Corticotropin releasing hormone Growth hormone releasing hormone Prolactin releasing hormone Gonadotropin releasing hormone
What is a pituitary gland
Acts as the body’s master gland ollowing chemical messages from the hypothalamus sends hormones to other glands that then lead to a response
What is the anterior pituitary gland
The anterior pituitary is supplied indirectly with arterial blood provides oxygen and nutrients, this blood transports hormones secreted by the hypothalamus
What are the five types of hormones that are released from the anterior pituitary gland?
Thyroid stimulus hormone Adrenocorticotropic hormone Growth hormone Prolactin Gonadotropins Follicle-stimulating hormone Luteinising hormone
Where does the Thyroid stimulus hormone travel to
to the thyroid gland
Where does Adrenocorticotropic hormone travel to
to the adrenal gland
What is growth hormone
a protein hormone that stimulates growth of bone and muscle in children. It also increases protein synthesis and metabolic processes that lead to growth
What is Prolactin hormone
is protein hormone is essential in lactation in females in males it helps enhance secretion testosterone and production of semen
What is the Gonadotropins hormone
Travels to the gonads – ovaries for females and testes for men
What is the posterior pituitary gland
it is made up of nervous tissue does not synthesise hormones of its own and is a hormone storage area.This network of nerve fibres allows the hypothalamus to transport its hormones to the posterior pituitary gland
What is the hypothalamic–hypophyseal tract
is the posterior lobe that is connected to the hypothalamus by a bridge of nerve axons
What are the two hormones released by the posterior pituitary gland
Vasopressin Oxytocin
Where is the pineal gland located
located beneath the corpus callosum.
What is the pineal gland main function
to help control the circadian rhythm by secreting the hormone melatonin.
What is circadian rhythm
the body’s internal 24-hour clock that regulates cycles of alertness and sleep by responding to certain changes
What is melatonin
is secreted in response to darkness. Therefore, during the day, its levels decrease due to excess light.
Where is the thyroid gland located
is located on the anterior surface of the neck, just below the larynx and sits in front of the tracheal.
What are the two lobes for the thyroid gland
left and right lobe is connected by the isthmus
