Glandular Epithelia:
Types of Secretion - Exocrine - define this |
When secretions are discharged onto the surface of the skin or onto epi surface lining in internal passageways that comm. with the exterior
-exocrine cells form pockets connected to epi surface by tubes, called ducts |
|
|
Glandular Epithelia:
Types of Secretion - Exocrine Categorization: Serous gland |
Secrete a watery solution that contains enzymes like salivary amylase in saliva
|
|
|
Glandular Epithelia:
Types of Secretion - Exocrine Categorization: Mucous gland |
Secrete glycoproteins called mucins that absorb water to form a slippery mucus, like mucus in saliva.
|
|
|
Glandular Epithelia:
Types of Secretion - Exocrine Categorization: Mixed Exocrine Gland |
Contain more that one type of gland cell and may produce different secretions, ex. submandibular gland
|
|
|
Glandular Epithelia:
Types of Secretion - Endocrine - define this |
When hormones are released by exocytosis from the gland cells into the fluid surrounding the cell and diffuse into the blood for dist.
|
|
|
Glandular Epithelia:
Types of Secretion - Endocrine - define this |
May be part of the epi surface like in the lining of the digestive tract or they may be sep. as in the pancreas, but no ducts are ever present
|
|
|
Glandular Epithelia:
Gland Structure - Unicellular glands |
Where epithelia contain scattered gland cells, the individual secretory cells are unicellular
|
|
|
Glandular Epithelia:
Gland Structure - Multicellular glands |
Include glandular epithelia and aggregations of gland cells that produce exocrine secretions; found in pockets set back from the epi surface, have 2 components: glandular and duct portions
|
|
|
Glandular Epithelia:
Gland Structure - Unicellular glands type: Goblet cells (Exocrine) |
Secrete mucins that form mucus; they are scattered among epi cells, ex: in the columnar epithelium of the intestines
|
|
|
Glandular Epithelia:
Gland Structure - Multicellular glands type: Secretory Sheet (exocrine) |
Glandular cels dominate the epi and release secretions to an inner compartment;
|
|
|
Glandular Epithelia:
Gland Structure - Multicellular gland organization: Gland shape |
-Tubular: cells arrang. in tube
-Alveolar/Acinar: cells arrang. in blind pockets -can have como of two, then put names together |
|
|
Glandular Epithelia:
Gland Structure - Multicellular gland organization: Duct pattern |
-Simple: if the duct doesn't branch
-Compound: if it branches repeatedly, most likely used by several glands |
|
|
Glandular Epithelia:
Modes of Secretion - Merocrine Secretion |
Where the secretory product is released through the exocytosis, most common mode of secretion; globlet cells release mucus via the merocrine secretion
|
|
|
Glandular Epithelia:
Modes of Secretion - Apocrine Secretion |
When the apical portion of the cytoplasm becomes packed with secretory vesicles before its shed; occurs in milk production
|
|
|
Glandular Epithelia:
Modes of Secretion- In both merocrine and apocrine secretion, does the nucleus and golgi apparatus stay intact? |
Yes, so the cell can still perform reparis and contnue to secrete.
