8) Intercalated disc functions:
These are the transverse bands which separates the adjacent ends in cardiac muscle fibres.
Function: To hold the adjacent cells together by providing sites of strong adhesion. The gap junctions produces diffusion of ions between cells and gives permission of waves to depolarization to spread over the entire heart by passing from cell to cell.
9) Nervous tissue is composed of neurons and two types of cells neurons and neuroglia or glial cells. There are six types of glial cells four found in nervous system and two found in peripheral nervous system.
Glial cells have function of support, protect and insulate neuron.
10) match the tissues
Simple squamous epithelium is present in part of basement membrane and walls of hollow organs hence (A).
Transitional epithelium-- Urinary bladder so matches (G). It consists of multiple layers. It also present in urethra, ejaculatory duct and renal pelvis.
Loose connective tissue-- it is present in air sacs of lungs. Hence match to (C) option.
Cardiac muscles are the part of heart. Hence matches with (J).
Nervous tissue is composed of brain, spinal cord and peripheral tissue hence matches to (F).
Stratified squamous nonkeratenized epithelium-- This tissue is present in the hollow organs lining, eye, skin and sorrounding many glands hence option (E) is matches.
Hyaline cartilage : joints, anterior ends of ribs and nose. Hence matches to (l).
Smooth muscles: These are present in the oral cavity, female reproductive organ. Hence matches to (D)
Dense regular collagenous connective tissue- It is present in tendons and ligaments (attach bone to bone).
Reticular connective tissue- It is present in the liver,spleen, lymph node, red bone marrow and blood vessels. Hence option (B) is matches.
