Name the endocrine glands that have a major endocrine function:
pineal gland, hypothalamus, pituitary gland, thyroid, parathyroids, thymus, pancreas, adrenals, and gonads (testes or ovaries)
Two systems regulate homeostasis:
endocrine system and nervous system
fast response system of the
Areas receptive to hormones are known as_________ and can be tissues or organs.
Name some effects of hormones.
2. changes and development, or maturation
4. sexual development
5. regulation of the sexual cycle
where are hormones located?
Name some of the organs in the body that have an endocrine function.
Heart, Kidneys, and Stomach
What does it mean to have an endocrine function?
produce hormones; picked up by blood capillaries and distributed throughout the body, type of secretion called "ductless secretion"
How do exocrine glands function?
they secrete material in tubules/ ducts (like sweat or salivary glands) or go directly to the surface (like the ovaries).
Where are the exocrine glands located?
sweat and salivary glands; ovaries
Where is the pineal gland?
in the mid-brain
(almost across from the hypothalamus, in a gap area)
How does the pineal gland function?
secretes melatonin ("hormone of darkness") regulates sleep wake cycles or circadian rhythms
production is inhibited by light and peaks in the middle of the night
where is the pituitary gland located?
below the hypothalamus
the master gland of the pituitary gland does what?
it produces hormones that control other endocrine glands
Name the 2 lobes of the pituitary gland.
the anterior lobe or adenohypopysis
the posterior lobe or neurophysis
What is the difference between the anterior and posterior lobes of the pituitary gland?
the anterior lobe produces hormones while the neurohypophysis
The anterior lobe or adenohypophysis of the pituitary gland secretes what hormones?
1. Growth Hormone (GH)
2. Prolactin (PRL)
3. Adenocorticotropic hormone (ACTH)
4. Thyroid Stimulating Hormone (TSH)
5. Follicle Stimulating Hormone (FSH)
6.Lutenizing Hormone (LH)
7. Melanocyte- stimulating hormone (MSH)
