Question

Which of the following types of tissue forms glands?
(A)Epithelial
(B)Muscular
(C)Nervous
(D)Connective

Answer 1

Hint: Glands are groups of cells present in our body that secretes important secretions to maintain certain functions in our body. They release it either in blood or on its outer surface.

Complete answer:
Glands are groups of cells that are formed from epithelial tissues and synthesized substances for release into the bloodstream or into cavities inside the body. The hormone is one of such substances secreted by the glands. The glands that release content into the bloodstream are known as endocrine glands whereas the exocrine ones secrete into cavities the body or its outer surface.

Additional Information:
Muscular tissue forms the muscles in animal bodies, giving rise to muscles' ability to contract and is formed during Embryonic Development through the process of myogenesis. They are made of elongated cells known as muscle fibers and are of three main types- Skeletal muscle, smooth muscle, and cardiac muscle.
Nervous tissue is the main tissue of the nervous system and is made of different types of neurons. They regulate and control our body parts as well as functions in sensory input integration, Homeostasis, and mental activity.
Connective tissue is developed from the mesoderm and is found between other tissues everywhere in the body. These are of two types- dense connective tissue and loose connective tissue.

So, the correct answer is “Epithelial”.

Note: Glands are formed from ingrowth of the epithelial surface in which in the beginning, it possesses a tubular structure and later on starts as a solid column of cells which subsequently becomes tubulated. Compound glands are formed as the column of cells splits or gives off offshoots. The gland that retains its shape as a tube is known as tubular gland but when the secretory portion of the gland gets enlarged and the lumen increases in size, it is known as alveolar or saccular glands.
