skin (epidermis) and organs (hair, nails, muscles, sensory receptors and glands) 

what does the integumentary system consist of?

conical projections of the dermis called dermal papillae (create the fingerprint)

why is the boundary between the dermis and the epidermis uneven?

what layer of skin contains accessory structures including: hair follicles, sebaceous glands and sweat glands?

what type of muscle form the arrector pili muscle that is attached to each hair follicle 

sudoriferous (sweat) glands are also called

which gland become active during puberty? (body oder)

in Brian/ spinal cord; allows control and coordination 

bc its made of connective tissue and blood vessels 

why do you bleed if you break through the epidermis and dermis?

abundant amounts of collagen fibers forming over the epidermal surface 

the dermis and and is composed of connective tissues along with the smooth muscle, nervous tissue, & blood 

what does the inner layer of skin consist of?

(subcutaneous) masses of areolar and adipose tissue that binds the skin to the underlying organs

in air sacs of lungs; diffusion of gases 

bc its made of strands of squamous tissue and no blood vessels 

why do you not bleed if you only break the epidermis?

blood vessels in dermis dilate merocrine sweat glands

skin becomes red, warm, swollen and painful 

in areas of abrasion; provides protection 

what binds the epidermis to underlying tissues 

found in tendons; resist twisting/pulling

the epidermis and is made of stratified squamous epithelium 

what does the outer layer of skin consist of?

external ear; provides flexible framework 

hollow internal organs; moves food and empties bladder 

under the most epithelial tissues; serves as binding material 

what do sebaceous glands release (associated with the hair follicles)

corneum (cute), lucidum *only in thick skin and palms and soles of feet* (little), granulosum (girls), spinosum (sing), basal (badly)

what are the layers of the epidermis (superficial --> deep)
