38. Stratefied Cuboidal: Function They protect the sweat glands, salivary glands and mammary glands. They aid in sweat secretion. They help in sperm production. They also aid in secretion of ovarian hormones. * Nafly Hussain*

40. Columnar Epithelia * Nafly Hussain*

41. Columnar Epithelia Pseudostratified Columnar Simple Columnar * Nafly Hussain*

42. Structure Pseudostratified Columnar All cells rest on the basement membrane but all cells do not reach the lumen. Thenuclei are found at different levels. Only a single layer of cells. but looks multilayered. Has its cell nuclei positioned in a manner suggestive of stratified. Simple Columnar Uni-layered The height of the cells may vary. Cells are elongated and column shaped. Characteristically their nuclei are also elongated and usually located near the base of cells. and at right angles to the base. The cells are longer than their width. * Nafly Hussain*

43. Functions Simple Columnar Epithelium The main function is protection. For example, the epithelium in the stomach and digestive tract provides an impermeable barrier against any bacteria that could be ingested but is permeable to any necessary ions . Simple columnar epithelial cells can specialize to secret mucus that coats and protects the surrounding surface from damage. simple columnar epithelium is also specialized to provide sensory input. simple columnar epithelium are very good at absorbing and transporting nutrients from locations like the small intestine . * Nafly Hussain*

45. Trap and move "pollutants" to the mouth where they are swallowed.

46. Secretes and propels mucus by ciliary actions.

47. Has an absorptive function. * Nafly Hussain*

48. * Nafly Hussain*

49. Location Simple Columnar Sites where chief function is – protection Eg. ducts of glands bronchioles Sites where cells can both secrete and absorb.Small intestine • Sites where the cells are specialized to secrete - surface lining of stomachcervical canal. Uterine tube * Nafly Hussain*

50. Eyes Ears Buccal cavity Digestive tract Reproductive organs * Nafly Hussain*

51. Location Pseudo stratified Columnar respiratory tract from nasal cavity to bronchi portions of male urethra. * Nafly Hussain*

52. Simple Epithelium Apical surface Columnar cell cytoplasm Tight junctions Other junctions, such as adherens or desmosomes Nucleus Basement membrane basal surface Basal surface * Nafly Hussain*

53. Pseudo stratified Epithelium * Nafly Hussain*

54. Adaptations Simple columnar. Cilia found on the luminal surface. Goblet cells within columnar cells. Microvilli specialized for absorption. * Nafly Hussain*

56. Has large microvilli or stereocilia onthe surface,in the male genital system. * Nafly Hussain*
