Flashcards do conjunto (15)
- 1—Pituitary Gland!
Anterior - left - endocrine - made mostly of epithelium
Posterior - right - exocrine - made mostly of neural tissue - 2—Posterior Pituitary!
Cells = pituicytes = glial cells = modified neuron
Hormones produced = Antidiuretic hormone (ADH) & Oxytocin
- 3—Anterior Pituitary!
Three cell types (ABC's):
1. Acidophiles
2. Basophils
3. Chromophobes
- 4—1. Acidophiles = love acid = second most common - lightly stained cytoplasm - pink color
*Hormones produced = GH, PRL (MSH)
2. Basophils = love basic items = most common - bottom circle where it is dark
*Hormones produced: TSH, ACTH, LH, FSH
3. Chromophobes = afraid of color = least common - middle purple color
*Hormones produced: we do not know
- 5—Thyroid!
Two types of cells:
1. Follicle cells
2. Parafollicular cells
- 6—Thyroid!
1. Follicle cells
*Simple cuboidal
*Hormones produced = T3 & T4
*T3 and T4 stored in these cells until they need to be released
*Thyroid hormone is the regulator of most human tissues in body to increase metabolism
2. Parafollicular cells
*Are in between follicles but not lining is
*Also known at C or clear cells
*Hormones produced: calcitonin
- 7—Parathyroid!
1. Chief cells
*Most common
*Dark purple
Hormones produced: parathyroid
2. Oxyphils
*More red cells
*Do not know what they do
- 8—Pancreas!
Cell types:
1. Acinar (not endocrine)
2. Alpha
3. Beta
- 9—1. Acinar (not endocrine)
*Exocrine cells with ducts
*Many of these cells! - 85%
*Release digestive enzymes to break down macromolecules
2. Alpha
*In the little cluster of cells - pancreatic islets - islets of Langerhans
*More red
*Hormones produced: glucagon
*Released when blood glucose levels are high
*Glucagon mostly goes to liver and is stored as glycogen
*When glycogen bonds break you get individual glucose molecules
3. Beta
*In the little cluster of cells - pancreatic islets - islets of Langerhans
*More blue
*Hormones produced: insulin
*Released when blood glucose levels are low
- 10—Adrenal Gland! (just be able to recognize it)
1. Adrenal cortex (outer)
2. Adrenal Medulla (inner)
- 11—1. ADRENAL CORTEX
*Hormones produced: steroid
*Three layers!
1. Zona glomerulosa - salty - aldosterone - increases sodium retention in the body
2. Zona fasciculata - sweet - cortisol - makes energy available for our bodies to use - increase fatty acid metabolism - elevates glucose levels
3. Zona reticularis - sexy - testosterone, estrogen, progesterone
2. ADRENAL MEDULLA
*Chromaffin cells
*Hormones produced: epinephrine & norepinephrine
- 12Pineal GlandRelease melatonin 24 hour light dark cycle
- 13Gonads and PlacentaGamete producing
- 14Endocrine organ location
- 15—
