Relationship between the Hypothalamus and Pituitary Gland - Posterior Lobe

Question 1

what does the hypothalamus do

Answer 1

The hypothalamus monitors hormone levels. It manufactures hormones released by the posterior lobe of the pituitary gland.

Question 2

what does the posterior lobe do

Answer 2

The posterior lobe only stores hormones

Question 3

describe how the posterior lobe releases hormones

Answer 3

These hormones (oxytocin + ADH) will be carried via a nerve cell to the posterior lobe of the pituitary gland to be stored. The neuron found in the hypothalamus will release a nerve impulse into the posterior lobe causing oxytocin or ADH to be released into the bloodstream.

Question 4

draw a table to compare and contrast the anterior and posterior lobes of the pituitary gland

Answer 4

anterior lobe
1. chemical control - released via a chemical (releasing factor)
2. manufactures hormones
3. stores the hormones
4. hormones mad in the anterior lobe

posterior lobe
1. nervous control - released via a nerve impulse
2. does not manufacture hormones
3. stores the hormones
4. hormones mad in the hypothalamus
