Inflammation of the serous membranes that line the chest cavity.

Generally located close to the surface of the skin.  It is capable of detecting sensations of light touch.

Composed of epithelial tissue and an underlying layer of specialized connective tissue.

"Cover or Protect"

Dermis
The deeper layer-filled with a dense network of interlacing fibers

Also called the superficials fascia

Not a part or layer of the skin.  It lies deep to the dermis and forms a connection between the skin and underlying structures of the body

Eccrine- Wide Spread
   Regular sweat glands
Apocrine Sweat Glands-  found primarily in the skin in the armpit and in pigmentes skin areas around the genitals

Extremelyfine, soft hair that babies are born with.

Small, cap-shaped cluster of cells where hair growth begins

The deeper of the two layers of skin.  Thicker that the epidermis

Respond to pain

composed exclusively of various types of connective tissue.  No epithelial cells are present in this type of membrane.

"Cover Joints"

Inflammation of the serous membranes in the abdominal cavity

Epithelia membranes

Line body surfaces opening directly to the exterior

The transitional area that serves as a point of "fusion" where skin and mucous membranes meet.

Connective

Lines the joint capsules that surround and attach the ends of articulating bones in moveable joints.

Secrete a thick, colorless lubrication fluid called synovial fluid.

Located deep in the dermis.  Capable of detecting deep pressure.

Small, cusion-like sacs found between many moving body parts.

Secrete oil for the hair and skin

Sebum- the oil secreted from the Sebgaceous glands

Most common type of skin cancer.  Usually appears on the upper face.  Originating in cells at the base of the epiderrmis.

Slow-growing malignant tumor of the epidermis

Detect low-frequency vibration

Upper region- characterized by parallel rows of tiny bumps called dermal papillae.

Epithelial Membrane
Lines body cavities and covers the surface of the organs in those cavities.

Parietal Portion- lines body cavities
Visceral Portion- covers organs
Pleura-thoracic cavity
Peritoneum- abdominal

Produced by subcutanious tissue, pigment gives color to the skin

Melanin-Brown Pigment

Melanocytes- the cells that produce pigment

The blue-gray color that appears when o2 levels decreas or blood flow is reduced

The outermost layer of the skin.
Stratum Germinativum-innermost layer
Keratin-water proof material that provide protection

Stratum corneum- tough outer layer

Used to determine the extent of injury from a burn.  The body is divided into 11 sections of 9% with the genitals making the extra 1%

the junction that exists between the thin epidermal layer of skin above and the dermal layer below

The most serious form of skin cancer starts from a benign mole and then transforms.

A tiny smooth (involuntary) muscle attatched to the base of a dermal papilla that contracts only when we are frightened or cold
