Thick skin: location and layers - Answer-Covers the palms
of the hands and soles of the feet
Has five layers of keratinocytes
What are the 5 strata of keratinocytes in thick skin -
Answer-1. Stratum basale
2. Stratum spinosum
3.Stratum granulosum
4. Stratum lucidum (missing in thin skin)
5.Stratum corneum
Bottom to top
What is the Stratum Basale? - Answer--Is attached to
basement membrane by hemidesmosomes
-Forms a strong bond between epidermis and dermis
-Forms epidermal ridges (basis of fingerprints)
,2|Page
-Dermal papillae (tiny mounds)- projections from the
dermis-Increase the area of basement membrane and
ttrengthen attachment between epidermis and dermis
-Has many basal cells, or germinative cells
What determines fingerprints? - Answer-Determined by
genetics and
uterine environment during fetal development.
Do identical twins have the same fingerprints? - Answer-
No
What are specialized cells of Stratum Basale? - Answer-1.
Merkel cells- specialized epithelial tactile cells
Found in hairless skin
Respond to touch (trigger nervous system)
2. Melanocytes
Contain the pigment melanin
Scattered throughout stratum basale
What is the Stratum Spinosum? - Answer-"the "spiny
layer"
,3|Page
-Produced by division of stratum basale
-Eight to ten layers of keratinocytes bound by
desmosomes
-Cells shrink until cytoskeletons stick out (looks spiny) -
under normal histological preperations
-Continue to divide, increasing thickness of epithelium
-Contain dendritic (Langerhans) cells, active in immune
response - defend against microorganisms that get past
superficial layers of epidermis and defend against
superficial skin cancers
Integumentary System- weight and area - Answer-Is the
largest system of the body
16% of body weight
1.5 to 2 m2 in area
How many parts makeup the integumentary system? -
Answer-The integument is made up of two parts
1. Cutaneous membrane (skin)
2. Accessory structures
Describe the Cutaneous Membrane - Answer-consist of
two components:
, 4|Page
Outer epidermis
Superficial epithelium (epithelial tissues)
Inner dermis
Connective tissues
Accessory Structure - Answer-Originate in the dermis
Extend through the epidermis to skin surface. Includes:
Hair, Nails, Multicellular exocrine glands
What Systems are connected to the Integumentary
system? - Answer-Cardiovascular system- By blood
vessels in the dermis
Nervous system- By sensory receptors that detect stimuli
for pain, touch, and temperature
Is the hypodermis part of the Integumentary system? -
Answer-No, Located below the dermis
-Composed of loose connective tissue: separates
integument from the deep fascia around organs
- Location of hypodermic injections
