Contusion

A closed wound commonly known as a bruise.

Hematoma

A closed wound where blood pools under the skin (blood clot)

Blister

A closed wound characterized by a raised bubble filled with fluid.

Frostbite

A closed wound caused by freezing of the skin and underlying tissues.

Avulsion wound

An open wound where a portion of skin is torn away.

Abrasion

An open wound caused by scraping of the skin.

Second Degree Burn

An open wound classified as partial thickness, affecting the epidermis and part of the dermis.

Laceration

An open wound with jagged cuts or tears.

Incision wound

An open wound with a clean, straight line.

Skin tears

Open wounds caused by the skin being ripped or pulled.

Puncture wound

An open wound resulting from a pointed object piercing the skin.

Sanguineous Drainage

A type of drainage that is bloody.

Serous Drainage

Clear, thin, and watery drainage.

Purulent Drainage

Thick, yellow, or green drainage indicating infection.

Serosanguineous Drainage

Light pink drainage that is thin and watery.

Hemostasis

The skin's first response to a wound, involving blood clot formation.

Vasoconstriction

The process where blood vessels tighten to minimize bleeding.

Inflammation

The body's response involving white blood cells that devour bacteria and damaged tissue.

Phagocytosis

The process of white blood cells engulfing and digesting cellular debris.

Vasodilation

The expansion of previously constricted blood vessels, occurring 2 to 3 days after a wound.

Remodeling

The final stage of the healing process where collagen forms connective tissue.

Medical Protection

The use of clean cloths or sterile dressings to protect the wound.

keratinocytes

produce keratin

Langerhan cells

immune system

melanocytes

produces melanin

merkel cells

nerves

basal layer

bottom layer of skin that contains stem cells responsible for generating new skin cells and where melanocytes and Merkel cells are also found.

Inflammation 

White blood cells(macrophages) devour bacteria and damaged tissueand release signaling molecules that promote healing.

Phagocytosis

previously constricted blood vessels expand

vasodilation

2 to 3 days after the proliferative stage occurs when the fibroblast cells enter the wound collagen deposition forms connective skin tissue to replace the fibrin 

remolding

healing process

Meissner’s corpuscles

are specialized nerve endings located in the dermis that respond to touch and pressure stimuli, playing a crucial role in the sensation of light touch

hypodermis

not apart of the skin, adipose and areolar tissue that provides insulation and cushioning, connecting the skin to underlying structures.

Carotene

yellow to orange

pigment, most obvious in the

palms and soles of the feet

Hemoglobin

a red pigment found in red blood cells that carries oxygen, contributing to the pinkish hue of the skin.
