Anatomy Lab 5 Integumentary System

Question 0

The epidermis is made up of what kind of tissue?

Answer 0

Stratified squamous epithelial tissue

Question 1

What are the 3 parts of the integumentary system?

Answer 1

Epidermis, dermis, hypodermis

Question 2

The papillary layer is composed of what kind of tissue?

Answer 2

Loose connective tissue

Question 3

The reticular layer is composed primarily of what kind of tissue?

Answer 3

Dense irregular connective tissue

Question 4

Define the cutaneous membrane.

Answer 4

The epidermis and dermis combined together

Question 5

What is the subcutaneous layer?

Answer 5

The hypodermis

Question 6

The hypodermis is composed mainly of what kind of tissue? What does it connect to?

Answer 6

Loose connective tissue and adipose; mainly muscle or bone

Question 7

What is the largest organ of the body?

Answer 7

Skin

Question 8

What are the 3 modes of secretion?

Answer 8

Holocrine secretion, apocrine secretion, merocrine secretion

Question 9

Cells using this mode of secretion produce their product into cytosolic vesicles, that then bind to the plasma membrane and open to the extracellular environment. This mode uses EXOCYTOSIS, and is invoked by sweat glands (eccrine & apocrine)

Answer 9

Merocrine mode of secretion

Question 10

This mode of secretion is invoked by the mammary glands. Cells using this method produce their product into cytosolic vesicles that aggregate to the apical surface of the cell. The plasma membrane at the lateral edges pinches off the apical portion that contains the secretions and releases it into the extracellular environment.

Answer 10

Apocrine mode of secretion

Question 11

This mode of secretion is found in sebaceous glands & hair follicles. It is only found in stratified epithelial tissue. Vesicles are filled with the cytoplasm, secretion discharges through cell lyses (breaks apart), all bits are emptied into extracellular environment. The cell dies.

Answer 11

Holocrine mode of secretion

Question 12

What is the function of the sebaceous glands?

Answer 12

Release an oily/waxy secretion over the entire body surface (except on palm and soles).

Question 13

The sebaceous glands use what mode of secretion?

Answer 13

Holocrine mode of secretion

Question 14

What are the 2 types of sweat glands?

Answer 14

Eccrine and apocrine

Question 15

Where are eccrine sweat glands located?

Answer 15

All over the body except for lips and penis

Question 16

Eccrine sweat glands are most numerous on what 3 parts of the body?

Answer 16

Palms, soles, and forehead

Question 17

Apocrine sweat glands remain inactive until _______.

Answer 17

Puberty

Question 18

Where would you mainly find apocrine sweat glands on the body?

Answer 18

Axillary, mammary, genital, and anal areas.

Question 19

Both sweat glands use what mode of secretion?

Answer 19

Merocrine mode of secretion

Question 20

Name difference btwn eccrine and apocrine sweat glands in terms of size, number, and type of secretion

Answer 20

Eccrine=smaller, more numerous, watery sweat
Apocrine=larger, less numerous, viscous secretion that contains lipids, proteins, steroids, and a small amnt of pheromones.
