The mesothelium or lining epithelium of the coelom is derived from which of the following?

The ciliated epithelium in our body may be found in

$A$ student was given a sample of tissue. He observes and concludes the following characters.
$(i)$ The cells are composed of a single layer of tall and slender cells.
$(ii)$ Their nuclei are located at the base.
$(iii)$ Free surface may have microvilli.
$(iv)$ It is found in the lining of stomach and intestine.
$(v)$ They help in secretion and absorption. Based on the above features identify the epithelium.

The inner wall of blood vessels and the heart is lined by an epithelium that is:

Match the following cell junctions with their characteristic features:

$(a)$ Tight junctions	$(i)$ Cement neighbouring cells together to form a sheet
$(b)$ Adhering junctions	(ii) Transmit information through chemicals to other cells
$(c)$ Gap junctions	(iii) Establish a barrier to prevent leakage of fluid across epithelial cells
$(d)$ Synaptic junctions	(iv) Cytoplasmic channels to facilitate communication between adjacent cells

Select the correct option from the following:

Identify the types of cell junctions that help to stop the leakage of the substances across a tissue and facilitation of communication with neighbouring cells via rapid transfer of ions and molecules.
