PAPER 2026 SOLVED QUESTIONS GRADED A+
◉ Simple Columnar Epithelium. Answer: Description: taller than
wider,Thick(protects), single layer elongated nuclei located near
basement membrane, can be ciliated or nonciliated
Function: cilia aide in moving egg cell, protects underlying tissues,
secretes(goblet cells) digestive fluids and absorbs(microvilli)
nutrients form digested food
Location: female reproductive tract(cilia), (non cilia) uterus and
digestive tract (stomach small and large intestines)
◉ goblet cell. Answer: specialized flask-shaped glandular cell,
secretes mucus(protective fluid)
unicellular gland found in columnar epithelium that secretes
mucous
unicellular exocrine gland
◉ Microvilli. Answer: tiny cylindrical process increase surface
membrane
projections that increase the cell's surface area
◉ Cilia. Answer: Tiny hairlike extensions that move together in a
sweeping motion
,◉ Pseudostratified Columnar Epithelium. Answer: Description:
appeared stratified/layer due to nuclei lying at more than one level ,
varies in shape all reach basement membrane, cilia, goblet cells
Function: Protects and absorb( mucus lining sticks and traps foreign
particles , cilia sweeps upward and out of airway)
Location: respiratory system
◉ Stratified squamous Epithelium. Answer: Description: many cell
layers (thick) cell division in deeper layer push older
upward(flattened-keratin) named for top layer, forms superficial
layer (epidermis)
Function:Protects
Location: oral cavities, esophagus, vagina, and anal canal ( these part
tissues aren't keratinized, they are soft and moist, cell on free
surface remain alive)
◉ Keratinization. Answer: older layers of cells are pushed upward
causing an accumulation of keratin(protein) that hardens and dies;
produce cover of dry , tough , protective material preventing water
and other from escaping and blocks chemicals and microbes from
entering.
◉ Stratified Cuboidal Epithelium. Answer: Description: two or three
layers of cuboidal cells
, Function: protects
Location: lines the lumen ducts of mammary glands, sweat glands,
salivary glands and pancreas, ovarian follicles and seminiferous
tubules (female and male reproductive systems)
◉ Transitional Epithelium. Answer: Description:
Function: specialized to change in response to increase tension(
contracts-several layers of irregular shaped cells, distends-tissue
stretch cell elongate) protects(form barrier , prevents contents of
urinary tract from diffusing back to internal)
Location: inner lining of urinary bladder and lines ureters and
superior urethra
◉ Glandular Epithelium. Answer: Description: one or more cells
constitutes a gland (exocrine, endocrine)
Function: produce and secrete substances into ducts or into body
fluids
Location: in columnar or cuboidal epithelium
◉ Exocrine glands. Answer: Definition: secretes products into ducts
opening onto surface, classified by ways of secretion
Ex: skin/lining of digestive tract
Merocrine/eccrine glands: release fluid by exocytosis (most)
apocrine glands: lose small portion of cell bodies during secretion
