Answer 1

1. Skin (cutaneous membrane)
2. Accessory structures

Question 2

What are the two components of skin (cutaneous membrane)?

Answer 2

1. Epidermis (epithelium)
2. Dermis (connective tissue)

Question 3

What are the three components of accessory structures?

Answer 3

1. Exocrine glands
2. Hair
3. Nails

Question 4

What are the four functions of the integumentary system?

Answer 4

1. Physical and immunological protection
2. Thermoregulation
3. Sensation
4. Metabolic functions

Question 5

What are the two metabolic functions?

Answer 5

1. Vitamin D synthesis
2. Stores energy as subcutaneous fat

Question 6

What are the four types of tissue?

Answer 6

1. Epithelium
2. Connective tissue
3. Muscle (smooth)
4. Nerve

Question 7

What are the two aspects of epithelium tissue?

Answer 7

1. Covers surface
2. Forms boundary

Question 8

What are the two aspects of connective tissue?

Answer 8

1. Supports epithelium
2. Provides strength and resiliency

Question 9

What are the two aspects of muscle (smooth) tissue?

Answer 9

1. Controls diameter of blood vessels (involuntary - synthesis autonomic response)
2. Adjusts hair position

Question 10

What are the three aspects of nerve tissue?

Answer 10

1. Controls smooth muscle
2. Generates sensation (tactile, pressure, temperature, etc)
3. Stimulates exocrine glands

Question 11

What are the three major characteristics of skin?

Answer 11

1. Largest organ system of the body
2. Covers area of 2m^2
3. Ranges in thickness between 0.5 mm and 4.0 mm

Question 12

Structure of SKIN from superficial to deepest (3):

Answer 12

1. Epidermis
2. Dermis
3. Hypodermis (subcutaneous layer)

Question 13

What does the peak-and-valley interface between the dermis and epidermis allow?

Answer 13

Allow for a tight bond between different layers of skin (can resist shearing stresses)
