New Jersey State Board Esthetics Practice Exam

Which of the following are examples of connective tissues?

1. Neurons and glial cells

2. Epithelial and muscle tissues

3. Tendons, elastin, and cartilage

4. Red and white blood cells

The correct answer is: Tendons, elastin, and cartilage

Connective tissues are a type of tissue that supports, binds together, and protects other tissues and organs in the body. They have diverse functions and structures, all of which serve to provide support and protection. Tendons, elastin, and cartilage are classic examples of connective tissues. Tendons connect muscles to bones, enabling movement, while cartilage provides flexible support and cushioning at joints, allowing for smooth articulation. Elastin is a key protein found in connective tissues that provides elasticity and resilience, helping tissues return to their original shape after stretching or contracting. Together, these components illustrate the fundamental roles connective tissues play in maintaining the structural integrity of the body and facilitating movement. The other options, while they may seem relevant, do not represent connective tissues. Neurons and glial cells are primarily components of nervous tissue; epithelial and muscle tissues are distinct types that serve specific functions for protection and movement, respectively; and while red and white blood cells are vital components of the blood, which is a connective tissue, the other two do not fit the classification of connective tissues.
