|<big>Describe the location of the Pituitary Gland.
||<font color="white"> <big>
*The pituitary gland, or hypophysis lies within a bony cavity, the Sella Turcica, in the base of the skull just ventral to the hypothalamus. It lies between the more rostral Optic Chiasma, and the more caudal Mammillary Bodies.

|<big>Which sections of the Pituitary Gland labelled above make up the Adenohypophysis and Neurohypophysis:

|-
|<big>What are the cell types within the Pars Distalis and what hormones do they produce?
||<font color="white"> <big>
*Corticotropes - POMC which is then cleaved to Adrenocorticotropin Hormone - ACTH
*Thyrotropes - Thyroid Stimulating Hormone
*Gonadotropes - Luteinising Hormone and Follicle Stimulating Hormone
*Lactotropes - Prolactin
*Somatotropes - Growth Hormone.
||[[Pituitary Gland - Anatomy & Physiology#Hormones of the Anterior Pituitary Gland|Answer article]]
|-
|<big>What is secreted by the Posterior Pituitary Gland and what are their actions:
||<font color="white"> <big>
*Oxytocin - Promotes milk let down and uterine contractions during parturtion.
*Anti Diuretic Hormone - ADH - Acts on the renal tubules to minimise water loss into the urine.
||[[Pituitary Gland - Anatomy & Physiology#Posterior Pituitary Gland|Answer article]]
|-
|<big>Decribe how Milk Let-Down is initiated:
||<font color="white"> <big>
*Impulses travel via superfical sensory pathways and the inguinal nerve.
*Afferent sensory neurons enter the lumbar part of the spinal cord to the thalmus.
*They reach the cell bodies of neuroendocrine cells
*Oxytocin is then released from the nerve endings in the posterior pituitary gland.
*Oxytocin enters capillaries and the systemic circulation.
*Mammillary cappillaries contract, pressure within the alveoli increases.
*Resistance in excretory ducts and teat canal is reduced.
*Increased milk outflow.
