Integumentary System Flashcards
movement
- cells change shape and
chemical composition (fills
with keratin)
Keratinization
It is the deepest epidermal layer
bond to the dermis via intertwining collagen
fibers, referred to as the basement membrane
Stratum basale
It produces melanin
Melanocytes
Which layer of the epidermis is composed of 8 to 10 layers of keratinocytes formed from cell division in the stratum basale and appears spiny due to desmosomes that bind the cells together?
Stratum spinosum.
The stratum spinosum is known for its spiny appearance under a microscope, caused by desmosomes that mechanically link the keratinocytes.
Which layer of the epidermis is characterized by a grainy appearance, with three to five layers of keratinocytes that become flatter, develop thicker cell membranes, and produce large amounts of keratin?
Stratum Granulosum
smooth, seemingly translucent layer of the
epidermis
Stratum Lucidum
most superficial layer of the epidermis and is the layer exposed to the outside environment
Stratum Corneum
IT contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands.
Dermis
more collagen fibers are oriented in some directions than in others
Cleavage line
produces sebum (oily, white
substance rich in lipids)
Sebaceous glands
Describe what is the difference and what it is between two colored disease eyes
Cyanosis - blue lacked of oxygen
Jaundice - yellowish eyes - liver is damaged by a disease
