Adherens junctions are essential for the cells to communicate in all the four basic types of tissue.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Explanation (300 words):<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Intercellular junctions are specialized structures that connect adjacent cells, playing crucial roles in communication, adhesion, and maintaining the structural integrity of tissues. Let&#8217;s analyze each option:<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A. &#8220;Adherens junctions are essential for the cells to communicate in all the four basic types of tissue.&#8221; \u2013 <em>Incorrect (thus the correct answer)<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adherens junctions are primarily involved in <strong>cell adhesion<\/strong>, not <strong>cell-to-cell communication<\/strong>. They link the actin cytoskeleton of one cell to that of its neighbor through cadherins, helping to maintain tissue integrity, particularly in <strong>epithelial and cardiac tissues<\/strong>. However, they are <strong>not essential for communication across all tissue types<\/strong> (epithelial, muscle, nervous, and connective tissues). Communication is mostly mediated by <strong>gap junctions<\/strong>, especially in cardiac and neural tissues.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>B. &#8220;Blood-brain barrier and outer layer of skin have tight junctions&#8221; \u2013 <em>Correct<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Tight junctions<\/strong> form a seal between adjacent cells, preventing the passage of substances through the space between cells. They are especially critical in the <strong>blood-brain barrier<\/strong>, where selective permeability is essential, and in the <strong>epidermis<\/strong>, to protect against external environments.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>C. &#8220;Gap junctions connect cardiac muscle cells and allow them to communicate with each other fast.&#8221; \u2013 <em>Correct<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Gap junctions<\/strong> allow direct cytoplasmic exchange of ions and small molecules between adjacent cells. In the <strong>heart<\/strong>, they are vital for the rapid propagation of action potentials, ensuring synchronized contraction.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>D. &#8220;Desmosomes are intercellular interactions between epithelial cells&#8221; \u2013 <em>Correct<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Desmosomes<\/strong> are strong, adhesive junctions found in <strong>epithelial tissues<\/strong>, anchoring cells together and providing mechanical strength, especially in skin and mucosa.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>E. &#8220;Intercellular junctions connect cell membrane between neighboring cells.&#8221; \u2013 <em>Correct<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is a general but accurate statement. All types of intercellular junctions (tight, adherens, desmosomes, gap) function at the <strong>cell membrane interface<\/strong> between adjacent cells.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, <strong>Option A is NOT correct<\/strong> about intercellular junctions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following statements is NOT correct about intercellular junctions?
