Body Membranes
This type of membrane lines cavities open to the external environment.
What are mucous membranes
These are skin cells that produce pigment
What are melanocytes
The anatomic name for sweat glands
What is sudoriferous
The deepest layer of the epidermis
What is stratum germinativum (basale)
This receptor is sensitive to hot & cold
What are free nerve endings
This connective tissue membrane lines joints and secretes fluid to keep them lubricated
What are synovial membranes
This substance toughens the skin and makes it water-resistant
What is keratin
The anatomic name for oil glands
What is sebaceous
The most superficial layer of the epidermis
What is stratum corneum
Nociceptors are sensitive to this type of stimulus
What is pain
This type of membrane has two layers and lines internal cavities
What are serous membranes

What is the dermis
This accessory organ is made of dead keratinized cells and acts as protection against UV rays
What is hair
This epidermal layer is only found in places like the hands, feet, and lips
What is stratum lucidim
These cutaneous receptor is sensitive to light touch.
What are Merkel discs and Meissner's corpuscles
Our skin is this type of membrane
What is cutaneous
What layer of skin tissue is avascular (no blood supply)
What is the epidermis
This accessory organ gives protection but also acts as a tool
What are nails
Epidermal layer where keratin starts to harden the cells
What is stratum granulosum
This cutaneous receptor is the most numerous and widespread
What are free nerve endings
This is the function that all membranes share in addition to serving as linings/coverings
What is the secrete lubricating substances
These finger-like projections connect the epidermis to the underlying dermis
What is dermal papillae
Tube surrounding each hair root
What is a follicle
Spiny, web-like layer of the epidermis
What is stratum spinosum
These sensory receptors are sensitive to deep touch, pressure and tissue distortion
What are Ruffini and Pacinian corpuscles
