Non-cellular layer that connects inner surface of the epithelial tissue to the connective tissue is
Factual
The type of epithelial cells which line the inner surface of Fallopian tubes, bronchioles and small bronchi are known as
Ciliated epithelium is a region of epithelium consisting of columnar or cuboidal cells bearing hair like appendages called cillia, that are capable of beating rapidly. Ciliated epithelium performs the functions of moving particles of fluids over the epithelial surface. Cuboidal ciliated epithelium occurs in certain parts of uriniferous tubules whereas columnar ciliated epithelium occurs in fallopian tubules, nasal passages, bronchioles, small bronchi and buccopharyngeal cavity of frog. It often occurs in the vicinity of mucus secreting goblet cells.
Squamous epithelium are found in lining of alveoli in the lungs and Bowman's capsule in the kidney. Columnar epitjelium are found in the lining layer of gastrointestinal tract, gall bladder, uterus etc. and cubical or cuboidal epithelium lines the salivary ducts, pancreated ducts, gastric glands, thyroid follicles, germinal epithelium of ovary, proximal part of uriniferous tubules etc.
Tadpoles of frog can be made to grow as giant sized tadpoles, if they are
Thyroxine, the principal hormone, of thyroid gland, is required for tissue differentiation and metamorphosis (the rapid tranformation from the larval to adult form) in amphibians. Thyroxine triggers a response from the hypothalamus, (probably by a genetic mechanism) followed by the production and release of TSH (Thyroid stimulating hormone), thus metamorphosis begins and tadpoles metamorphose into frogs. Thiourea is an organic compound of carbon, nitrogen, sulphur and hydrogen, with the formula CSN2H4 OR (NH2)2CS. It is similar to urea. except that oxygen atom is replaced by a sulphur atom.
Tendon and ligament are example of
Fibres and fibroblasts are compactly packed in the dense connective tissues. Orientation of fibres show a regular or irregular pattern and are called dense regular connective tissues. In the dense regular connective tissues, the collagen fibres are present in rows between many parallel bundles of fibres. Tendons, which attach skeletal muscles to bones and ligaments which attach one bone to another are examples of this tissue.
The sclerites in exoskeleton of cockroach are joined to each other by :
In cockroach, exoskeleton has hardened plates called sclerites that are joined to each other by a thin and flexible articular membrane called as arthrodial membrane.
The triangular head of cockroach is made by fusion of how many segments :
Head of cockroach is triangular in shape.. It is formed by the fusion of six segments and shows great mobility in all directions due to flexible neck.
Which mouth part of cockroach has grinding and incising part ?
Malpighian tubules of cockroach are lined by which of the following cells ?
Excretion in cockroach is performed by Malpighian tubules. Each tubule is lined by glandular and ciliated cells. They absorb nitrogenous waste products and convert them into uric acid which is excreted out through the hindgut.
Complete the following sentence by choosing the appropriate option:
Digestive juice in cockroach is secreted by a ring of blind tubules which are ______ in number.
A ring of 6-8 blind tubules called hepatic or gastric caecae is present at the junction of foregut and midgut, which secrete digestive juice.
Yellow coloured thin filamentous rings present at the junction of midgut and hindgut which help in excretion are how many in number ?
At the junction of midgut and hindgut, a ring of 100-150 yellow coloured thin filamentous- malpighian tubules is present. They help in removal of excretory products from haemolymph.
