Layers of skin

Question 1

Meissner’s corpuscles

Answer 1

sense light touch

Question 2

Pacinian corpuscles

Answer 2

sense deep pressure

Question 3

Sebaceous glands

Answer 3

secrete lipids that inhibit bacteria and lubricate the hair shaft

Question 4

Sweat glands

Answer 4

secrete water, waste products and electrolytes, in part to cool skin and reduce body temperature

Question 5

Epidermis

Answer 5

provides mechanical protection against invasion by microorganisms (stratified squamous epithelium)

Question 6

Dermis has two layers….

Answer 6

Papillary layer and reticular layer

Question 7

layer of areolar tissue, with capillaries and sensory neurons that supply the epidermis

Answer 7

Papillary layer

Question 8

thicker layer, consists of dense, irregular connective tissue and networks of blood vessels, lymph vessels, and nerve fibers

Answer 8

Reticular layer

Question 9

subcutaneous layer, consists of areolar and adipose tissue

Answer 9

hypodermis

Question 10

innermost “basal” layer of epidermal cells, includes cells capable of cell division

Answer 10

stratum basale

Question 11

adjacent to stratum basale, where few cells may continue to divide

Answer 11

stratum spinosum

Question 12

where cells begin to produce keratin and the granular keratohyalin (epidermis, adjacent to stratum spinosum)

Answer 12

stratum granulosum

Question 13

thick skin of palms and soles, which is extensively keratinized

Answer 13

stratum lucidum

Question 14

out layer of epidermis, consists of dead cells that contain keratin and are relatively water resistant

Answer 14

stratum corneum

Question 15

special cells found in the basal layers, they make pigment melanin and transfer it to keratinocytes

Answer 15

Melanocytes (cells found in deep layers are in light-skinned ppl) (Melanin is protective against UV induced damage)
