Assertion & Reason Test: Structural Organisation in Animals - Question 8

In multicellular organism, a group of similar cells along with intercellular substances perform a specific function. Such organization is called tissue. Epithelial tissue provides covering or lining for some part of the body. Cells are compactly packed without intercellular space. It may be simple, compound, cuboidal or of columnar type. The connective tissues.
They are most abundant and widely distributed tissues which link and support the other tissues. All connective tissue except blood, secretes fibres of structural protein called collagen or elastin to provide elasticity an flexibility. The cells or fibres of the connective tissue may be loosely or arranged or compactly packed. Cartilage, bones and blood are specialized connective tissue. In muscle tissue muscle is made up of long cylindrical fibres arranged parallel to each other. Fibres are composed of fine fibrils called myofibrils. Muscle fibres contract and relax in response to stimulation. The unit of neural system is neuron. Neuroglial cell protect and supports the neuron. When neuron gets stimulated, electrical impulses are generated that travel along the plasma membrane (axon). The tissues organize to form organs which in turn associate to form organ system in multicellular organisms.

Q. Crypts of Lieberkuhn are:

Detailed Solution for Assertion & Reason Test: Structural Organisation in Animals - Question 8

Crypts of Lieberkuhn are intestinal glands. They are simple tubular glands that lie between the finger-like projections called, villus of the inner surface of the small intestine. The cells of these glands secrete intestinal juice.

Q. Transitional epithelium is present:

Detailed Solution for Assertion & Reason Test: Structural Organisation in Animals - Question 9

Transitional epithelium : consists of many layers of cells, which are thin and stretchable. It is present over urinary bladder and helps in its expansion during urine storage

Q. Which tissue are mainly present in the inner surface of bronchioles?

Detailed Solution for Assertion & Reason Test: Structural Organisation in Animals - Question 10

Some columnar or cuboidal cells bear cilia on their free surface they are called ciliated epithelium. Their function is to move particles or mucus in a specific direction over the epithelium. They are mainly present in the inner surface of hollow organs, e.g. fallopian tube, bronchioles.
