controlled by nervous systemthermoregulation and extreation
cell within epidermis responsible for pigmentation
melanocyte
When do apocrine glands become active?
puberty
sialography
x-ray of salivary glands and ducts
Stratum layer with spiney projections. Some mitosis occurs. Langerhans nd keratinocytes found here
Stratum spinosum
stratum corneum 2 functions
protects and waterproofs

Tanning 
vitamin D
allows the intestines to absorb calcium and phosphate
Cancer
this occurs when genetic change result in turning on, or not turning off, genes which regulate normal cell division and tissue growth.

What is the most easily regulated loss of heat through the skin?
Evaporation
via what process is melanin transferred to other cells?
long cell process
Sensory Receptors
transmits sensation to the brain such as cold, pain, heat, touch, and pressure
malignant neoplasm
composed of invasive cells that spread to remote areas of the body.  Cells show altered function.
True or false: Dermis makes up the greatest portion of the integumentary system?
True.
subcutaneous layer
bottom layer of the skin containing fatty tissue
2 distinct regions of skin and the subcutaneous region deep to the skin
epidermis
dermis
hypodermis
Dense Connective Tissue
Mostly occupied by fibers, collagenous fibers, packed tightly and make tendons.
Papillary layer
outer layer of dermis closest ot epidermis. loose connective tissue
 
 
 
Merkel Cells (81)
Also called tactile cells, these cells signal the brain when an object has touched the skin.
 
5-1
1st Degree Burns
Involve only the epidermis. Heals by regeneration of the epidermis in days with no scarring. Symptoms include redness, slight edema (swelling), and pain.
Only type located in stratum basale of epidermis
merkel disc
Anatomy of Hair:hair root plexus
surrounding hair follicles are dendrites of neurons that are sensitive to touch
Skin forms what to distinct layers?
Epidermis and the dermis.
Epidermal dendritic (Langerhans) cells
Macrophages that help activate immune system.
contusion (def)
def: bruise / blow to the body that doesn't cause a break in the skin
3 types of cells within stratum spinosum
1. keratinocytes2. melanocytes3. Lagerhans
What is flushing and what causes it?
redness of the skin;fevers
What are the two types of sweat glands?
Eccrine and Apocrine
system is made up of
skin, nails, hair, sweat glands, sebaceous glands(oil)
What are other names for the hypodermis?
Subcutaneous layer and superficial fascia
What does the synovial membrane consist of and what is it's function?
they consist of fibrous connective tissue over loose connective tissue and adipose tissue. they form the inner linnings of jointsFound: at the end of bones and freely movable jointsFunction: cells secrete synovial fluids which lubricates the ends of bones
Parts of a Hair
Hair shaft - section of hair above the surface of the skin. Cells are dead and keratinized.
Hair root - part of the hair that is in the skin. Cells are dead and keratinized.
Hair bulb - deepest part of the hair. Within the bulb is the hair matrix, the still living cells that divide and push older cells upward.
Hair receptor - Nerves around the hair follicle that detect movement of the hair.
Piloerector muscle - smooth muscle that makes the hair stand up and makes "goosebumps" on skin in response to cold and fear.
Hair is formed in what three concentric layers?
Medulla, cortex, and then the cuticle.
What is the medical use of hypodermis?
Its loose, spongy texture and rich blood supply make it ideal for rapid and relatively pain0free absorption
where in epidermis are Merkel cells located?
in stratum basale (where they come in contact with the nerve & Meissner corpuscle)
