Nails, hoofs and horns are examples of epidermal derivatives. Claws are modified into nails, which are characteristic of mammals. Hoofs are characteristic of ungulates. Horns are found in hoofed mammals (Artiodactyla and Perissodactyla) only. All the three (i.e., nails, hoofs and horns) are modification of stratum corneum.
Pseudostratified epithelium always consists of a single layer of irregularly shaped columnar cells touching the basement membrane, i.e., the long cells with oval nuclei and short cells with rounded nuclei. Some of the cells (long cells) extend from the basement membrane to the surface. Hence, although epithelium is one cell thick but it appears to be multilayered or stratified, thus called Pseudostratified.
Many olfactory glands (Bowman’s glands) occur below the olfactory epithelium that secrete mucus over the epithelium to keep it moist.
Q4. Which of the following is common British frog?
Rana temporaria is common British frog
Vitamin-K (phylloquinone) is the anti-haemorrhagic vitamin or factor, reported and named by a Danish scientist, Dam as coagulation factor (Danish term), who got the Nobel Prize for it in 1943. It is necessary for the synthesis of prothrombin (the precursor of thrombin) in the liver for normal clotting of blood. Thus, vitamin-K helps in blood clotting, prevention of haemorrhage and excessive bleeding in wounds.
Pericardium. A frog heart is solid muscular organ situated in the upper half of body cavity. It is three chambered with two auricles and one ventricle. The ventricle is incompletely divided by an interventricular spetum, while auricles are completely divided by interauricular spetum. Heart is covered by a membrane called pericardium. The potential space between heart and pericardium is called pericardial space. This space is fluid filled and the fluid here is called pericardial fluid. The heart of frog pumps mixed blood as lungs are not much functional is than and most of the oxygenation of blood takes place throngle skin.
Lymph is the fluid filtered out from the blood capillaries. It lacks RBCs and proteins
The type of epithelial cells that line the inner surface of fallopian tubes, bronchioles and small bronchi, are known as ciliated epithelium.
Connective tissues ranges from soft connective tissues to specialised types, which includes cartilage, bone, and blood.
