What is this?
Identify the labels/function |
Thyroid gland
A-follicular cells, make t3/t4 B-Colloid-where the thyroglobulin is stored C-parafollicular cells-secrete Calcitonin |
|
|
What type of epithelium lines the thyroid follicles?
|
Simple cuboidal
|
|
|
Where do follicular cells secrete into?
|
The colloids, NOT into capillaries.
|
|
|
How can you tell whether the thyroid is storing or secreting hormones? (activity of the gland)
|
High cuboidal lining means it is secreting (smaller lumen), lower cuboidal means that it is storing (larger lumen)
|
|
|
What happens to a follicular cell when TSH stimulates it?
|
It uptakes the colloid through endocytosis and then attacks it with lysosomes, liberating the T3 and T4 so that it can go into the blood
|
|
What is this?
Name the cells and their functions. |
A-oxiphil cells-(pink)-inactive cheif cells with no secretoyr granules, but with more mitochondria
b-chief cells-secrete parathyroid hormone |
|
|
What are the two embryo logic origins of the pituitary gland
|
neural ectoderm and the oral ectoderm
|
|
|
What are the three parts of the anterior pituitary, and what is found there?
|
Pars-distalis-
--acidophils--somatotrophs (GH), mammotropes(prol) --basophils-thyrotropes (TSH), Gonadotropes (LH,FSH), Corticotropes (ACTH) Pars intermedia --Basophils ----alpha melanocyte ----prolactin releasing hormone Pars tuberalis |
|
|
What are the three parts of the posterior pituitary and what is found there?
|
Pars nervosa
---herring bodies -----vasopressing -----oxytocin --pituicytes infundibulum median eminance |
|
Identify the labels
|
A-pars intermedia
b-pars nervosa c-pars distalis d-pars tuberalis |
|
What is this?
Identify the labels |
Pars distalis
MN-SandM is acidic, even the bastards Can Get That A-chromophobe b-acidophils (mammotropes, somatotrophs) c-basophils (thyrotropes, gonadotropes, corticotropes) |
|
What is this? What is A, what is found here
|
Pars intermedia
A-colloid cyst-remnants of rathke's pouch basophils here produce alpha melanocyte stimulating hormone and also prolactin releasing factor |
|
What is this, what are the arrows pointing to?
|
Pars nervosa, herring bodies (store oxytocin and vasopressin)
Surrounded with pituicytes (similar to astrocytes) |
|
|
What part of pars nervosa produces oxytocin?
|
Paraventricular nuclei (MN oxygen in my park)
|
|
|
What part of the pars nervosa produces vasopressin?
|
Supraoptic nuclei
|
|
What is this? What makes the cortex and what makes the medulla? What is made in the cortex and what is made in the medulla?
|
Adrenal gland
Cortex=mesoderm, medulla-neural crest endoderm! Cortex secretes-aldosterone, cortisol medulla-catecholamines |
|
What is this?
name the layers- |
Adrenal cortex- MN- (medulla) Real Fuckin' Good (outside)-adrenaline makes me feel real fucking good from the inside out!
A-Reticularis-pink splotchy F-Fasciculata-spongy with white areas (b/c of fat used to make steroid hormones) G-Glomerulosa-not as spongy |
|
Which layer secretes aldosterone?
Which layer secretes cortisol and androgens? Which layer is stimulated by Angiotensin 2? What are all 3 layers stimulated by? |
C-glomerulosa=aldosterone
B and A Fasciculata-secretes glucocorticoids and androgens C is stimualted by angiotensin 2 All three layers are stimulated by corticotropin |
|
What is this? What kinds of cells are here and what do they secrete?
|
Adrenal medulla; chromaffin cells; catecholamines nor epi and epi (and dopamine)
|
|
What is the top arrow pointing to, what is the bottom arrow pointing to?
Where is this? |
Ganglion cell; blood vessel (hormones secreted into here); Adrenal medulla
|
