1. Kidney Tubules 2. Thyroid gland 3. Small ducts of glands 4. Ovary surface (Germinal Epithelium)
SIMPLE CUBOIDAL EPITHELIUM
26
Consists of a single layer of Tall, column-like cells.
SIMPLE COLUMNAR EPITHELIUM
27
Nuclei are elongated and usually located near the base of the cell.
SIMPLE COLUMNAR EPITHELIUM
28
1. Absorption, Protection, and secretion. 2. Movement of substances
SIMPLE COLUMNAR EPITHELIUM
28
1. Lining of the entire digestive tract ( Stomach, SI, and LI)
SIMPLE COLUMNAR EPITHELIUM
29
Uterine tubes- (Ciliated type helps move the egg)
SIMPLE COLUMNAR EPITHELIUM
30
Respiratory tract- (Cilia help trap and move mucus)
SIMPLE COLUMNAR EPITHELIUM
31
-Has hair-like cilia on the surface. -Found in the respiratory tract, uterine tubes. * Helps move mucus and other substances.
Ciliated Simple Columnar Epithelium
32
- Lacks cilia but may have microvilli for increased absorption - Found in the digestive tract (stomach, intestines) -Functions in nutrient absorption and mucus secretion.
Non-Ciliated Simple Columnar Epithelium
33
Appears stratified (multiple layers) but is actually a single layer.
PSEUDOSTRATIFIED EPITHELIUM
34
Nuclei are at different heights, giving a false impression of layering.
PSEUDOSTRATIFIED EPITHELIUM
35
Often contains goblet cells that secrete mucus.
PSEUDOSTRATIFIED EPITHELIUM
36
May have cilia to help move mucus and trapped particles.
PSEUDOSTRATIFIED EPITHELIUM
37
Type of epithelial tissue that appears multilayered due to nuclei being at different levels but is actually a single layer of cells.
PSEUDOSTRATIFIED EPITHELIUM
38
Secretion - Goblet cells produce mucus. Protection - Traps and removes debris in the airways. Movement - Cilia help move mucus in the respiratory tract.
PSEUDOSTRATIFIED EPITHELIUM
39
Many layers (usually cuboidal/columnar at bottom and squamous at top)
STRATIFIED SQUAMOUS EPITHELIUM
39
1. Respiratory tract (trachea, bronchi, nasal cavity). 2. Male reproductive system (epididymis, vas deferens).
PSEUDOSTRATIFIED EPITHELIUM
40
A multilayered epithelial tissue designed for protection against mechanical stress, dehydration, and pathogens
STRATIFIED SQUAMOUS EPITHELIUM
41
1. Protection 2. Prevention of water loss 3. Maintains moisture
STRATIFIED SQUAMOUS EPITHELIUM
42
STRATIFIED SQUAMOUS EPITHELIUM: → Epidermis of the skin (outermost layer).
keratinized type
43
STRATIFIED SQUAMOUS EPITHELIUM: → Mouth, throat and anal canal.
Non-keratinized type
44
Many layers * Very specialized - cells at base are cuboidal or at surface will vary. * Change between stratified & simple as tissue is stretched out.
TRANSITIONAL EPITHELIUM
45
1. Allows stretching (change size)
TRANSITIONAL EPITHELIUM
46
Urinary bladder, ureters & urethra
TRANSITIONAL EPITHELIUM
47
One or more cells that make and secrete products.
GLANDS
48
protein in aqueous solution: hormones, acids, oils
Secretion
49
* No duct releases secretion into blood vessels.
ENDOCRINE GLANDS
50
* Thyroid, adrenal and pituitary glands
ENDOCRINE GLANDS
51
* Often hormones
ENDOCRINE GLANDS
52
Contain ducts, empty onto epithelial surface
EXOCRINE GLANDS
53
Sweat, Oil glands, Salivary glands, Mammary glands
EXOCRINE GLANDS
54
single, unbranched duct
Simple duct structure
55
branched
compound duct structure
56
shaped like a tube
Tubular
57
simple branched tubular example
stomach (gastric) glands
57
has both tubes and sacs in gland
Tubuloalveolar
57
simple tubular example
intestinal gland
57
shaped like flasks or sacs
Alveolar
58
simple alveolar example
no important example in humans
59
simple branched alveolar example
sebaceous glands
60
compound tubular example
brunner's glands of small intestine
61
compound alveolar example
Mammary glands
62
compound tubuloalveolar example
salivary glands
63
Just released by exocytosis without altering the gland at all. Ex: Sweat glands and salivary glands
Merocrine
64
-The gland ruptures and releases secretion and dead cells as well. -Sebaceous (oil glands on the face) only face
Holocrine
