Question A1 to A10

Name 10 endocrine organs

Name 10 endocrine organs
  • Pituitary gland
  • Thyroid gland
  • Parathyroid glands
  • Adrenal glands
  • Pancreas
  • Kidney
  • Testis
  • Ovary
  • Corpus luteum
  • Pineal gland

Question B1 to B4

For each of the following 4 slides

Which gland is arranged as:

Which hormone is secreted by:


  • C1: Pineal gland
  • C2: Testis
  • C3: Pancreas
  • C4: Thyroid gland

Which hormone is secreted by:

  • C1: Pineal gland = melatonin
  • C2: Testis = testosterone
  • C3: Pancreas = glucagon, insulin, somatostatin, pancreatic polypeptide
  • C4:Thyroid gland = thyroxine, triiodothyronine

Which hormone is secreted by:

  • D1: Leydig cells
  • D2: Oxyphil cell
  • D3: Follicular cell
  • D4: Somatotropes

Which hormone is secreted by:

  • D1: Leydig cells = testosterone
  • D2: Oxyphil cell = none
  • D3: Follicular cell = thyroxine, triiodothyronine
  • D4: Somatotropes = growth hormone

Which cell synthesize:

  • E1: ACTH
  • E2: Oxytocin
  • E3: Vasopressin
  • E4: PTH

Which cell synthesize:

  • E1: ACTH = basophils in the pituitary gland
  • E2: Oxytocin = neurons in the hypothalamus
  • E3: Vasopressin = neurons in the hypothalamus
  • E4: PTH = Chief cells in the parathyroid

In which glands are these cells located:

  • F1: Chromaffin cells
  • F2: Pituicytes
  • F3: Granulosa cell
  • F4: Alpha cells

In which glands are these cells located:

  • F1: Chromaffin cells = adrenal medulla
  • F2: Pituicytes = pars nervosa of the posterior pituitary
  • F3: Granulosa cell = ovarian follicle
  • F4: Alpha cells = pancreas

Give two anatomical relations for each of the following:

  • G1: Thyroid
  • G2: Parathyroid
  • G3: Adrenal glands
  • G4: Pineal gland

Give two anatomical relations for each of the following:

  • G1: Thyroid = anterior neck, below the laryngeal prominence, in front of trachea
  • G2: Parathyroid = anterior neck behind the thyroid gland
  • G3: Adrenal glands = superior poles of the kidneys
  • G4: Pineal gland = in the midline of the brain behind the third ventricle

Pituitary gland

How does the pituitary and hypothalamus communicate?

2 ways

Thyroid gland

Four elements making up the thyroid

Thyroid gland

  • Follicle
  • Follicular epithelium
  • Parafollicular cells
  • Colloid
  • Identify them on the next slide

Chief cells = majority

Oxyphil (acidophil) = single/groups

Adrenal glands

Capsule

Cortex - how many zones?

Medulla

Hormones of each?

Pineal Gland
