Major protein of connective tissue is:
The organic portion or protein fibers found in connective tissues are either collagen, elastic, or reticular fibers. Collagen fibers provide strength to the tissue, preventing it from being torn or separated from the surrounding tissues.
Light bands of muscle fibre are made of the protein:
Canaliculi are found associated with:
Processes from osteoblasts are found in :
The bone marrow is composed of :
The longitudinal canals of the bone are called :
Volkmann's canals occur in :-
A tissue is a :
Endothelium of the inner surface of blood vessels in vertebrates is formed
Cells of squamous epithelium are
The protein deposited in the dead superficial cells that make the skin epithelium impervious to water is
Correct Answer :- a
Explanation : Keratinised stratified squamous epithelium is a compound epithelium which covers the dry surface of skin. It has many layers of epithelial cells .The deeper layers are formed by polygonal cells but superficial layers constitute horny, scale like remains of dead squamous cells .Heavy deposits of the insoluble protein keratin in the dead superficial cells make the epithelium impervious to water and highly resistant to mechanical abrasions.
Horns of most mammals are composed of
Mammary glands are modified
Which of the following tissue has matrix, that is the source of its structural and functional performances?
Wrinkling in old age is due to
Dermis of mammalian skin is mainly composed of
Fat is abundant in
Adipose tissue, or fat, is an anatomical term for loose connective tissue composed of adipocytes.
Its main role is to store energy in the form of fat, although it also cushions and insulates the body.
Obesity in animals, including humans, is not dependent on the amount of body weight, but on the amount of body fat - specifically adipose tissue.
Cartilage is produced by
Bone forming cells are
Bone marrow is important for
Haversian system is typically found in bones of
Mammalian erythrocytes are
Life span of RBC is
RBC's also known as red blood cells are formed in the bone marrow by erythropoiesis. They have an average lifespan of 120 days. After ageing, they are selectively recognized in the spleen, liver and lymph nodes by macrophages followed by phagocytosis. This process is called eryptosis
So, the correct answer is '120 days'.
