12 Jun Patrick SCIENCE 111 – The cutaneous membrane is divided

Question
• 1 The cutaneous membrane is divided into two sections: the superficial__________________ is composed of stratified squamous epithelial tissue, while the deeper_________________________ is composed of connective tissue and houses blood vessels and accessory structures.

•

• 2 The most numerous cell found within the epidermis is the_______________________ , which will gradually flatten and fill with tough protein as they mature.

•

3 Although the skin is resistant to water entry and exit, some water is lost still lost through evaporation of interstitial fluids through the sweat pores. This is known as________________________ perspiration, in contrast with fluids lost via sweating, which is known as__________________ perspiration.

4 Match the layers of the epidermis and dermis to the descriptions that best matches them.

5Name the thick layer of areolar and adipose tissue that lies below the dermis, and which stabilizes the position of the skin while still allowing it free movement is ___________________________________

6The deepest layer of the dermis is primarily composed of______________________ (two words) connective tissue, while the superficial layer is primarily composed of _______________connective tissue.

7 Which layer of the dermis houses blood capillaries and the dermal papillae?

8.The integument plays a vital role in the synthesis of vitamin___________________ , which requires exposure to UV radiation (obtained from sunlight).

9 is __________________a dark black, brown, or yellow-black pigment which protects the nucleus of keratinocytes from UV radiation. This pigment is produced by___________________

10 Other pigments that contribute to skin color include the reddish ,___________________ which also transports oxygen, and the yellow-orange ___________________, which is stored in adipose cells.

While most of the visible hair is nonliving, it is produced by the hair______________________, a diagonal structure composed of both epithelial and connective tissue.

11 The___________________of the hair is the visible portion above the surface of the integument, while the__________________ of the hair is located below the surface, and terminates in the rounded, inferior bulb.

12 True or false: hair covers every portion of the integument

•

• 13 _______________________ glands produce watery secretions that are released onto the surface of the integument by long, coiled ducts. They are found virtually everywhere on the human body.

• ___________________Glands are located within the axillary, pubic, anal, and facial region (for males). These glands typically release their viscous secretions into the follicle of nearby hairs.

______________________glands produce thick, oily or greasy secretions, and typically release their products into an attached hair follicle.

14 Sebaceous glands, unlike sweat glands, use a _______________ method of secretion, meaning that the cells are destroyed and must be replaced periodically.

Sweat glands use a ______________ method of secretion, releasing the sweat via vesicles without harming the cell.

List any one example of an accessory structure for the integumentary system.________________________________
