Which of the following types of tissue forms glands?

(A)Epithelial

(B)Muscular

(C)Nervous

(D)Connective

Glands are specialized groups of cells formed from epithelial tissue. They are responsible for synthesizing and releasing substances into the bloodstream or into body cavities. One such substance is a hormone, secreted by glands.

• Endocrine glands: Release their secretions (like hormones) directly into the bloodstream.
• Exocrine glands: Release their secretions into body cavities or onto the body surface (e.g., sweat glands, salivary glands).

Correct Answer: Epithelial

Additional Information on Other Tissues

1. Muscular Tissue
   • Forms the muscles of the body.
   • Enables contraction and movement.
   • Develops during embryonic growth through myogenesis.
   • Made of elongated cells called muscle fibers.
   • Types: Skeletal muscle, Smooth muscle, Cardiac muscle.
2. Nervous Tissue
   • Main tissue of the nervous system, consisting of neurons.
   • Functions: Regulates body functions, integrates sensory input, maintains homeostasis, and supports mental activity.
3. Connective Tissue
   • Originates from the mesoderm.
   • Found between other tissues throughout the body.
   • Functions: Support, binding, and protection.
   • Types: Dense connective tissue and Loose connective tissue.
