The function of the gap junction is to

A.

performing cementing to keep neighbouring cells together

B.

faciliate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules

C.

seperate two cells from each other

D.

stop substance from leaking across a tissue

Explanation

A gap junction may nexus or macula communicans. These are specialised intercellular connection between a multitude of animal cell-types. They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells.

Choose the corectly matched pair.

A.

Tendon-Specialised connective tissue

B.

Adipose tissue-Dense connective tissue

C.

Areolar tissue-Loose connective tissue

D.

Cartilage-Loose connective tissue

Explanation

Areolar tissue is a loose connective tissue, and provide flexibility and cushioning. Adipose tissue is also loose connective tissue while, the tendon is a dense connective tissue, which connect the muscles with the bone. Cartilage is composed of specialsed connective tissue called chondrocytes that produce a large amount of extracellular matrix composed of collagen fibre.

Which of the following is correctly states as it happens in the common cockroach?

A.

Oxygen is transported by haemoglobin in blood

B.

Nitrogenous excretory product is urea

C.

The food is ground by mandibles and gizzard

D.

malpighian tubules are excretory organs projecting out from tthe colon

Explanation

In cockroach, mandibles are a pair of hard, strong, large, dark coloured triangular, structures which move in horizontal motion and crush food between them. Gizzard or proventriculus has an outer layer of thick circular muscles and thick inner cuticle forming six highly chitinous plate called teeth. The gizzard acts as the grinding chamber and helps in grinding the food particles.

The kind of epithelium which forms the inner walls of blood vessels is

A.

cuboidal epithelium

B.

columnar epithelium

C.

celiated columnar epithelium

D.

squamous epithelium

Explanation

Simple squamous eepithelium consists of only one layer of flat, scale like cells usually polygonal cells, which are closely fitted together like the tiles of a mosaic. It is also known as pavement epithelium. It forms lining of blood vessels, lymph vessels, heart, peritoneum, pleura, Bowman's capsule etc.

The epithelial tissue present on the inner surface of bronchioles and fallopian tubes is

A.

cuboidal

B.

glandular

C.

Ciliated

D.

squamous

Explanation

Ciliated columnar epithelium lines respiratory tract (lower end of bronchi), fallopian tubes, ventricles of brain (ependyma) central anal of spinal cord, etc.

Cuboidal epithelium occurs in certian parts of nephrons of the kidneys.

Glandular epithelium are specialized for secretory activites, eg., unicellular, multicellular, exocrine, endocrine, heterocrine glands, etc.

Squamous epithelium forms lining of blood vessels, lymph vessel, heart, peritoneum, pleura, Bowman's capsule, etc.

Explanation

In epithelial tissue, at place the adjacent cells form ion-rich gap or cell junctions for intercellualr communication and chemical exchange. These junctions probably do not provide physical support.
