Q

Name three neurocrine examples

A

Adrenal gland

Hypothalamus

17
Q

Name all the major endocrine glands/organs.

Others include stomach, liver, heart

A 
Hypothalamus
Pituitary gland
Pineal gland
Thyroid
Parathyroid
Thymus
Pancreas
Adrenal glands
Testes/Ovaries
Placenta in babies
18
Q

Where is the thymus located?

A

superior mediastinum (top of heart and between lungs)

19
Q

What is the function of the thymus?

A

Matures T cells

Thymosin (hormone that promotes t cell maturation)

20
Q

Name 4 different (chemical) types of hormones?

A

Peptide Hormone
Steroid Hormone
Catecholamines
Thyroid Hormone

21
Q

Examples of Peptide Hormone? 2

A

Insulin, Glucagon, Prolactin, ACTH, PTH, Gastrin

22
Q

Examples of Steroid Hormone? 2

A 
Oestrogen, 
androgens
aldosterone, 
progesterone
cortisol
23
Q

Examples of Catecholamines? 2

A

Adrenaline,

noradrenaline

24
Q

Examples of Thyroid Hormone? 1

A

Thyroxine,

triiodothryonine

25
Q

Function of hypothalamus?

A

Food (Feeding, satiety, GIT regulation)
Fun
Fever (Thermoregulation, panting, sweating, shivering)
Fornication (Emotion, sexual behaviour)

26
Q

Explain the Hypothalmic Pituitary throid axis?

Explain the feedback loops

A 
HYPOTHALAMUS
Thyroid release hormone (TRH)
ANTERIOR PITUITARY 
Thyroid Stimulating Hormone (TSH)
THYROID
T4 (thyroxine) and T3
  • T3&T4 have a short term negative feedback loop to ANT PITUITORY
  • Long negative feedback loop to HYPOTHAL
27
Q

HPA axis?

A 
HYPOTHALAMUS
CRH (corticotropin release hormone)
ANT PITUITARY
ACTH (adrenocorticotropic hormone)
Adrenal Cortex
Glucocorticoids (CORTISOL)

Cortisol has a neg feedback on ANT P and HYPO

28
Q

Which part of the adrenal gland is the medulla?

A

Centre

29
Q

What type of cells live in the adrenal medulla?

What do they release?
Input?

A 
Chromaffin Cells (modified neurons)
Receive SNS input and release A and NA
30
Q

Where (What organ/tissue) does the Adrenal medulla activation come from?

A

Hypothalamus

31
Q

What hormones are produced in the posterior pituitary?

A

oxytocin and

ADH (antidiuretic hormone [vasopressin])

32
Q

What does the pineal gland produce?

A

It produces melatonin

Melatonin is involved in control of circadian rhythmn

Melatonin inhibits release of gonadotrophins (LH and FSH)

calcifies in early
adulthood and is therefore visible on skull x-rays
