This epitheium gives errorenous impression that there is one more layer of cells. The nuclei of these cells are disposed at different level. Cilia are never present on true stratified epithelium.
Is a Stratified epithelium which contains cells that, due to stretching, change their shape, hence the name “TRANSITIONAL”. Also known as urothelium . Found in urinary tract.
This properties allows for liquid to be store i.e. urine in the bladder ( an organ where this tissue is found) The apical cells are rounded and give an umbrella shaped or dome cells. The basal cells are roughly cuboidal. Intermediate cells are polygonal.
GLANDULAR EPITHELIA A gland is one or more cells which produce and secrete a product called secretion.
Characteristic of the lining of the gastrointestinal tract. Glands that have this epithelium are1.Exocrine gland: these glands secrete their products into a system of channels or that convey the product to its final destination. E.g salivary gland.2.Endocrine gland:secrete their products or hormones into the underlying connective tissue and release their secretion directly into the blood. E.g thyroid gland.
1.STRATIFIED SQUAMOUS - skin,oral cavity,oesophagus,vagina etc.2.GLANDULAR - GIT,pancreas,salivary gland,endocervix,endometrium,thyroid etc.3.TRANSITIONAL - urinary bladder,ureter,pelvis of kidney etc.
1.Fibroblasts2.Adipose tissue3.Smooth muscle fibre and skeletal muscle.
These maintain the integrity of supporting tissues by continuous slow turnover of the extracellular matrix constituents. Fibroblasts synthesize and secrete collagen molecules then assembles into fibrils that are cross linked into fibres in the extracellular matrix.
Most numerous cells of connective tissue. Concerned with the production of collagen fibres. Collagen fibres provides strength. Also produce reticular and elastic fibres. In tissue sections appear to be spindle shaped and nucleus is flattened. Show branching processes when seen from surface.
Cells which are adapted for storage of fat called as adipocytes. Adipose tissue has important role general metabolic process. Two main types:1.White adipose tissue : found in deep layers of skin. E.g adults2.Brown adipose tissue: small amount found in humans. E.g children
Nutrition Mechanical function , keeps them in position. Cushioning effect. Insulation Heat generator.
It is composed of elongated,multinucleate contractile cells k/s muscle fibres bound together by collagenous supporting tissue. Muscle is made up of numerous small fasciculi. Each muscle fibre has multiple nuclei arranged at the cell periphery.
Cells are elongated,spindle shaped cells with tapered ends. Nucleus is centrally located in the cytoplasm at the widest part of the cell. Smf are bound together in irrerular,branching fasciculi, and these fasciculi are functional contractile unit.
