Exam 2 Review Guidance: Connective Tissue, Epithelial Tissue, and Integumentary System

Q1. What are the three components found in all connective tissue?

Background

Topic: Connective Tissue Structure

This question tests your understanding of the basic structural components that are common to all types of connective tissue in the body.

Key Terms and Concepts:

• Cells

• Fibers

• Ground substance

Step-by-Step Guidance

1. Recall that connective tissue is made up of living cells embedded in a non-living matrix.

2. Identify the three main components: the cells (which vary by tissue type), the protein fibers (such as collagen, elastic, and reticular), and the ground substance (the material that fills the space between cells and fibers).

3. Think about how these components contribute to the function and structure of connective tissue.

Q2. Name and describe the three types of fibers found in connective tissue.

Background

Topic: Connective Tissue Fibers

This question is about identifying and describing the three main types of protein fibers that provide support and structure in connective tissue.

Key Terms:

• Collagen fibers

• Elastic fibers

• Reticular fibers

Step-by-Step Guidance

1. List the three types of fibers found in connective tissue.

2. For each fiber type, recall its main structural characteristics (e.g., thickness, flexibility, strength).

3. Describe the primary function of each fiber type in connective tissue.

Q3. What are the different types of epithelial tissue, their anatomy, and their location in the body?

Background

Topic: Epithelial Tissue Types

This question tests your knowledge of the classification of epithelial tissues based on cell shape and layers, as well as their anatomical locations.

Key Terms:

• Simple vs. stratified epithelium

• Squamous, cuboidal, columnar cells

Step-by-Step Guidance

1. Recall the two main criteria for classifying epithelial tissue: number of cell layers and cell shape.

2. List the main types: simple squamous, simple cuboidal, simple columnar, stratified squamous, stratified cuboidal, stratified columnar, pseudostratified columnar, and transitional epithelium.

3. For each type, briefly describe its structure and give an example of where it is found in the body.

Q4. What is the difference between brown and white fat?

Background

Topic: Adipose Tissue Types

This question is about distinguishing between the two main types of adipose tissue and understanding their functions and characteristics.

Key Terms:

• Brown adipose tissue (BAT)

• White adipose tissue (WAT)

Step-by-Step Guidance

1. Recall the main function of white fat (energy storage, insulation, cushioning) and brown fat (heat production).

2. Think about the cellular differences: brown fat cells contain more mitochondria and are more vascularized than white fat cells.

3. Consider where each type is typically found in the body and their roles in metabolism.

Q5. What is the main anatomical difference between bone and cartilage?

Background

Topic: Connective Tissue Types

This question focuses on comparing the structure and composition of bone and cartilage, two specialized connective tissues.

Key Terms:

• Osteocytes (bone cells)

• Chondrocytes (cartilage cells)

• Matrix composition (mineralized vs. non-mineralized)

Step-by-Step Guidance

1. Recall that both bone and cartilage have cells embedded in an extracellular matrix.

2. Identify the main difference in the composition of their matrices (bone is mineralized, cartilage is not).

3. Think about how this difference affects their function and physical properties (rigidity vs. flexibility).

Q6. According to the book, what is the greatest risk factor for skin cancer?

Background

Topic: Integumentary System – Skin Cancer

This question tests your understanding of the main risk factors for developing skin cancer as discussed in your textbook.

Key Terms:

• Ultraviolet (UV) radiation

• Genetic predisposition

Step-by-Step Guidance

1. Recall the environmental and genetic factors that contribute to skin cancer risk.

2. Think about which factor is most emphasized in your textbook as the greatest risk.

3. Consider how this risk factor can be minimized or prevented.

Q7. What is the “rule of nines”?

Background

Topic: Integumentary System – Burns

This question is about a clinical tool used to estimate the percentage of body surface area affected by burns.

Key Terms:

• Rule of nines

• Burn assessment

Step-by-Step Guidance

1. Recall that the rule of nines divides the body into sections, each representing a percentage (usually multiples of nine) of total body surface area.

2. Think about how this rule helps clinicians quickly estimate burn severity and guide treatment.

3. List the main body regions and their corresponding percentages according to the rule.

Q8. What is the difference between endocrine and exocrine glands?

Background

Topic: Glandular Tissue

This question tests your understanding of the structural and functional differences between endocrine and exocrine glands.

Key Terms:

• Endocrine glands (ductless, secrete hormones into blood)

• Exocrine glands (have ducts, secrete onto surfaces)

Step-by-Step Guidance

1. Recall the main function of endocrine glands and how their secretions reach their target organs.

2. Contrast this with exocrine glands, which use ducts to transport their secretions to body surfaces or cavities.

3. Think of examples of each type of gland in the body.
