Mark the given statements True (T) or False (F).

(i) Squamous epithelium is found in wall of blood vessels and air sacs of lungs.

(ii) Cuboidal epithelium is found in ducts of glands and Henle’s loop of nephrons.

(iii) Columnar epithelium lines the inner surface of stomach and intestine.

(iv) The columnar or cuboidal cells bearing cilia on their surface are called ciliated epithelium and are present in inner surface of solid organs like bronchioles and fallopian tubes.

(v) The goblet cells of alimentary canal has unicellular type of glandular epithelium whereas salivary gland has multicellular type.

(vi) Compound epithelium covers the dry surface of the skin, moist surface of buccal cavity, pharynx, innerlining of duct of salivary glands and of pancreatic duct.

(vii) Tight junctions help to stop substances from leaking across a tissue whereas gap junction facilitate cells to communicate with each other by connecting the cytoplasms of adjoining cells.

(viii) Adhering junctions performs cementing to keep neighbouring cells together.

(ix) In all connective tissue the cells secrete fibres of structural proteins called collagen or elastin.

(x) Tendon attach skeletal muscles to bones and ligament attach one bone to another and both are example of loose regular type of connective tissue.

(xi) The cells of cartilage called chondrochytes are enclosed in large cavities within matrix secreted by them.

(xii) The cells of bone called osteocytes are present in the spaces called lacunae.

(xiii) The bone-marrow in all bone is the site of production of blood cells.

(xiv) The fibres of muscle tissue are composed of numerous fine fibrils, called myofibrils.

(xi) The smooth muscle fibres taper at both ends (Fusifrom) and show straiation.
