ANP Unit 2 Exam Review: Integumentary, Skeletal, and Muscular Systems – Step-by-Step Study Guidance

Q1. List the functions of the integumentary system and briefly describe each.

Background

Topic: Integumentary System Functions

This question tests your understanding of the various roles the integumentary system (skin and its derivatives) plays in the human body.

Key Terms:

• Protection

• Sensation

• Thermoregulation

• Excretion

• Vitamin D synthesis

• Immune defense

• Water retention

Step-by-Step Guidance

1. List each function of the integumentary system (see key terms above).

2. For each function, write a brief description of how the skin or its structures accomplish that role. For example, consider how the skin acts as a barrier for protection, or how sweat glands contribute to thermoregulation.

3. Think about examples for each function (e.g., how sweating helps cool the body, or how melanocytes protect against UV damage).

Q2. What is another name for the skin?

Background

Topic: Integumentary System Terminology

This question checks your knowledge of anatomical terminology for the skin.

Key Term:

• Cutaneous membrane

Step-by-Step Guidance

1. Recall the scientific term used to refer to the skin as an organ.

2. Think about how this term is used in context (e.g., cutaneous receptors, cutaneous glands).

Q3. What are the accessory structures of the integument?

Background

Topic: Integumentary System Anatomy

This question asks you to identify structures associated with the skin but not part of the main layers.

Key Terms:

• Nails

• Hair

• Glands (sebaceous, sweat, ceruminous, mammary)

• Arrector pili muscles

• Nerves and receptors

Step-by-Step Guidance

1. List all structures that are considered accessory to the skin.

2. For each, briefly note its function (e.g., what do sebaceous glands secrete?).

Q4. What are the two layers of the “true” skin?

Background

Topic: Skin Structure

This question focuses on the layers of the dermis, which is considered the "true" skin beneath the epidermis.

Key Terms:

• Reticular layer

• Papillary layer

Step-by-Step Guidance

1. Recall the two main layers of the dermis.

2. Identify which is superficial and which is deep.

3. Briefly describe the tissue type and main features of each layer.

Q5. List the layers of the epidermis from superficial to deep for thin skin.

Background

Topic: Epidermal Layers

This question tests your ability to recall the order of the epidermal layers in thin skin.

Key Terms:

• Stratum corneum

• Stratum granulosum

• Stratum spinosum

• Stratum basale

Step-by-Step Guidance

1. Start with the most superficial layer and work your way to the deepest.

2. Remember that thin skin lacks one of the layers found in thick skin.

3. List the layers in order, noting their main characteristics if possible.

Q6. List the layers of the epidermis from superficial to deep for thick skin.

Background

Topic: Epidermal Layers (Thick Skin)

This question is similar to the previous one but includes the extra layer found in thick skin.

Key Terms:

• Stratum corneum

• Stratum lucidum

• Stratum granulosum

• Stratum spinosum

• Stratum basale

Step-by-Step Guidance

1. List all five layers from superficial to deep.

2. Identify which layer is unique to thick skin.

3. Consider where in the body thick skin is found.

Q7. What areas of the body would we expect to find thick skin?

Background

Topic: Skin Types

This question asks you to recall where thick skin is located and why it is found in those areas.

Key Terms:

• Soles of feet

• Palms of hands

• Fingertips/toes

Step-by-Step Guidance

1. Think about which body parts experience the most friction and need extra protection.

2. List these areas and consider why thick skin is advantageous there.
