Simple squamous epithelium found in serous membranes lining cavities and surrounding organs is called
mesothelium
hyaline epithelium
areolar CT
endothelium
The Correct Answer is A
A. mesothelium: Mesothelium is a specialized simple squamous epithelium that lines the serous membranes of body cavities, including the peritoneum, pleura, and pericardium. It provides a smooth, friction-reducing surface and facilitates the movement of organs within these cavities.
B. hyaline epithelium: Hyaline epithelium is not a recognized tissue type. Hyaline typically refers to cartilage, not epithelial tissue, and does not line serous membranes.
C. areolar CT: Areolar connective tissue is a loose connective tissue that supports and cushions organs, but it is not an epithelial layer and does not form the lining of serous membranes.
D. endothelium: Endothelium is a simple squamous epithelium that lines blood vessels and the heart, not serous cavities. It functions primarily in exchange of materials and maintaining vascular homeostasis.

Correct Answer is B
Explanation
A. skeletal MT:Skeletal muscle tissue is striated and voluntary, with long multinucleated fibers. The nuclei are located at the periphery of the cells, making it different from the muscle type described.
B. cardiac MT:Cardiac muscle tissue is striated and involuntary, with cells that usually contain one centrally located nucleus. It also features intercalated discs that allow synchronized contraction, matching the characteristics given.
C. smooth MT:Smooth muscle tissue is involuntary but non-striated. The cells are spindle-shaped with a single central nucleus, so it does not meet the description that includes striations.
D. All types of muscle tissue have these characteristics:Not all muscle types share striations, involuntary control, and a single central nucleus. This description specifically fits cardiac muscle tissue rather than all types.
Correct Answer is B
Explanation
A. it is located just below the epidermis and protects the dermis from shock:The hypodermis is located beneath the dermis, not just the epidermis, and its role is more about cushioning and insulation rather than directly shielding the dermis from shock.
B. the major part of its makeup is adipose, which serves as an effective shock absorber:The hypodermis contains a large amount of adipose tissue that cushions underlying structures, distributes pressure, and absorbs mechanical shock.
C. the cells that make up the hypodermis secrete a protective mucus that absorbs shock:The hypodermis does not secrete mucus; this function is unrelated to connective tissue structure and physiology.
D. it has no delicate nerve endings and can therefore absorb more shock:The absence of many nerve endings does not make the hypodermis a shock absorber. Its cushioning effect is due to adipose tissue composition, not nerve distribution.
