Which layer contains no blood vessels or nerves?
Epidermis
Which epidermal layer is found only in the palms of the hands and the soles of the feet?
the stratum lucidum
A needle would pierce the epidermal layers of the forearm in which order?
corneum, granulosum, spinosum, basale
The skin; composed of epidermal and dermal layers
Cutaneous Membranes
Pertaining to under the skin
Subcutaneous
Deepest layer of the epidermis consisting of stem cells capable of undergoing cell division to form new cells
Stratum Basale
Bottom layer of the epidermis
Stratum Basale
What cell produces the pigment melanin?
Melanocytes
Your skin and hair are parts of your ___________
Integumentary system
Which layer contains accessory structures such as sweat glands, sebaceous glands, and hair follicles?
Dermis
The epidermis is composed of _____
Stratified squamous epithelium
The oldest cells of the epidermis will be found here
Stratum Corneum
What cell detects touch and sensory sensations?
Merkel (Tactile) Cells
What cell produces keratin, which allows for waterproofing of the skin, nails, and hair?
Keratinocytes
What cell detects produces an immune response against pathogens entering the skin?
Langerhans (Dendritic) cell
The cells that make up the majority of the layers of the epidermis are known as
Keratinocytes
A melanocyte is?
A cell that creates melanin
Is found on the stratum basale
Plays a role in determining skin color
All of the above
All of the above
Which is NOT part of the integumentary system?
Muscles
Which layer of skin is mostly composed of adipose tissue?
Hypodermis
What layer is the second to the bottom of the epidermis?
Stratum Spinosum
What layer is the 3rd from the bottom in the epidermis?
Stratum Granulosum
What is the clear layer of the epidermis, 2nd from the top with 5 layers?
Stratum Lucidum
What is the top layer of the epidermis
Stratum Corneum
The dermis is made up of what type(s) of tissue?
Areolar Connective Tissue, Dense Connective Tissue
The Dermis is made of two parts called the ______ layer.
Papillary, Reticular
Finger-like projections that glue the dermis to the epidermis
Dermal Papillae
Layer that provides the Stratum Basale with nutrients
Papillary
These are arranged in unique patterns that show through the epidermal surface making our fingerprints visible.
Dermal Papillae
Layer of dermis under stratum basale
Papillary Layer
Layer of skin under epidermis
Dermis
Bottom layer of dermis
Reticular Layer
Layer of skin above dermis
Epidermis
The outermost layer; 20-30 cell layers thick; cells are dead skin protection
Stratum Corneum
Thin and transparent, clear layer; found only in thick skin
Stratum Lucidum
These cells synthesize skin pigment to give skin and hair its color; found in the deepest layer of the epidermis
Melanocytes
Macrophages that help activate our immune system
Langerhans’ cells
Function as sensory receptors for touch
Merkel cells
Which layer of the dermis contains pain and touch receptors and epidermal ridges?
Papillary
What layer of the skin contains sweat glands?
Dermis
Glands and hair follicles grow in the
Dermis
The dermis is ___________ than the epidermis.
Thicker
This layer is made up of connective tissues, blood and lymphatic vessels, nerve fibers, hair follicles, and sebaceous and sweat glands.
Dermis
