Ehlers-Danlos syndrome is a hereditary disorder that affects collagen production. What type of tissue would be most affected?
A. Nervous tissue
B. Connective tissue
C. Muscle tissue
D. Epithelial tissue
Answer (2)
Ehlers-Danlos syndrome primarily affects connective tissue due to dysfunction in collagen production. This leads to symptoms involving skin, joints, and blood vessels. Therefore, the correct answer is Option B: Connective Tissue.

Ehlers-Danlos syndrome (EDS) is primarily a connective tissue disorder. This syndrome affects the production of collagen, which is a crucial protein that provides strength and elasticity to connective tissues throughout the body.
Why Connective Tissue is Most Affected:
Role of Collagen: Collagen is a major component of connective tissue. It helps support and bind other tissues in the body, such as skin, tendons, ligaments, and blood vessels.
Effects of Defective Collagen Production: In Ehlers-Danlos syndrome, genetic mutations affect collagen's structure and production, leading to weak or overly flexible connective tissues. This can result in symptoms like hypermobile joints, stretchy skin, and fragility in blood vessels or organs.
Examples of Affected Areas: Connective tissues are found throughout the body. Thus, EDS can lead to a variety of symptoms depending on which type of connective tissue is affected. This includes the skin, joints, and even internal structures like the walls of blood vessels and the eyes.
Given this information, the type of tissue most affected by Ehlers-Danlos syndrome is:
(B) Connective tissue
This disorder underscores the importance of connective tissue in maintaining the structural integrity of many body systems.
