pseudostratified and glandular epithelium Flashcards
state the characteristics of long cells of pseudostratified
they extend up till free surface, the nucleus is oval but not present at the base, they have goblet cells at the base
state the characteristics of the short cells of the pseudostratified
don’t extend up to the free surface, nucleus is rounded, absence of goblet cells
give examples of ciliated and non-ciliated pseudostratified epi
ciliated- trachea, bronchioles of respiratory tract
non-ciliated— urethra of male, parotid salivary gland
examples of unicellular and multicellular glands of glandular epithelium
uni -> goblet cells, paneth gland
multi -> salivary, pituitary, thyroid etc
ductless glands are also called, what do they secrete and their examples:
endocrine, hormones are secreted,
eg: pituitary gland, thyroid gland
glandular epi that has ducts are what glands
exocrine {pour their secretions to target organs}, mucus gland, salivary gland pancreatic, mammary gland
what are heterocrine glands, also give examples
they act like both endocrine and exocrine, egs are the pancreas, gonads
based on the mode of secretion give three types of glands
merocrine, apocrine, and holocrine
give examples of merocrine glands
salivary, pancreas, sweat ,intestinal, goblet glands etc
give examples of apocrine
mammary, axillary sweat glands etc
give examples of holocrine
sebaceous glands
