Gland with a duct through which secretions are transported to the sight of activity
The Growth hormone:
Stimulates body growth
Maturation of hair follicles
regulates metabolism
Increases size of cells
What is the name of the brain which Controls the release of various hormones from the anterior pituitary...?
(a)
Which organ does the Adrenocorticotropic hormone target?
Adrenal Cortex

Which hormones are not produced by the Anterior Pituitary lobe?
Releasing and inhibiting factors
Prolactin
Antidiuretic hormones
FSH
How many hormones does the Anterior Pituitary Lobe secrete?

5
6
7
Which hormones are secreted by the posterior pituitary lobe?
Oxytocin
Antidiuretic hormone
Growth Hormone
Thyroid Stimulating hormone
Which of the following is correct?
The Thymus Stimulating hormone targets the thymus gland and stimulates the thymus to produce and release thymosine
The Thyroid Stimulating hormone targets the thyroid gland and stimulates the thyroid to produce and release thyroxine.
The Thyroid Stimulating hormone targets the parathyroid gland and stimulates the thyroid to produce and release calcitonin.
The Thyroid Stimulating hormone doesn't target the thyroid gland and stimulates the thyroid to produce and release thyroxine.
Which of these are all the hormones of the anterior pituitary lobe?
Growth hormone, Follicle stimulating hormone, Luteinising hormone, Thyroid stimulating hormone, Adrenotropic hormone, antidiuretic hormone
Growth hormone, Follicle stimulating hormone, Luteinising hormone, Thyroid stimulating hormone, Adrenocorticotropic hormone and Prolactin
Growth hormone, Follicle stimulating hormone, Luteinising hormone, Thyroid stimulating hormone, Adrenocorticotropic hormone, antidiuretic hormone
Growth hormone, Follicle stimulating hormone, Luteinising hormone, Thymoid stimulating hormone, Adrenocorticotropic hormone, antidiuretic hormone
The role of prolactin is to:
Develop the breasts females
Increase testosterone in males
Increase milk production females
Increase sperm production in males
Which of the following definitions apply to 'receptor sites'
Areas on the cell membrane of a target cell which can combine with a hormone (for proteins).
Some hormones (steroids) which are lipid based easily pass through the cell membrane and their receptor sites are on the nucleus.
Small binding sites on the extracellular part of the cell membrane which bind to their corresponding proteins.
A site for receptors to bind to with their corresponding 'key'.

no
yes
The hypothalamus secretes hormones to the __________ pituitary gland via neurosecretory cells. These include Oxytocin, _______________ and ______________________.
Posterior, Antidiuretic Hormone, releasing and inhibiting factors
The hypothalamus doesn't create hormones!
There is a network of blood vessels instead of neurons which carry these hormones
Posterior, Prolactin and FSH
