詞彙表[编辑]

網狀組織(Areolar)
Areolar connective tissue is a pliable, mesh-like tissue with a fluid matrix and functions to cushion and protect body organs. It acts as a packaging tissue holding the internal organs together and in correct placement.
基底層(Basal lamina)
基底層 (often erroneously called basement membrane) is a layer on which epithelium sits. This layer is composed of an electron-dense layer (lamina densa) between two electron-lucid layers (lamina lucida), 大約 40-50 nm 厚(with exceptions such as the 100-200 nm glomerular basement membrane).
Dermis
The dermis is the layer of skin beneath the epidermis that consists of connective tissue and cushions the body from stress and strain. The dermis is tightly connected to the epidermis by a basement membrane.
Epidermis 
The epidermis is the outermost layer of the skin. It forms the waterproof, protective wrap over the body's surface and is made up of stratified squamous epithelium with an underlying basal lamina.
Fibroblasts
A fibroblast is a cell that makes the structural fibers and ground substance of connective tissue.
Hair follicle
A hair follicle is part of the skin that grows hair by packing old cells together.
Hypodermis
The hypodermis (also called the hypoderm), is the lowermost layer of the integumentary system in vertebrates. It is derived from the mesoderm, but unlike the dermis, it is not derived from the dermatome region of the mesoderm.
膿皰瘡(Impetigo)
This is a superficial skin infection most common among children age 2–6 years. People who play close contact sports such as rugby, American football and wrestling are also susceptible, regardless of age. The name derives from the Latin impetere ("assail"). It is also known as school sores.
Melanocytes
These are cells located in the bottom layer of the skin's epidermis and in the middle layer of the eye, the uvea. Through a process called melanogenesis, these cells produce melanin, a pigment in the skin, eyes, and hair.
Melanoma
A melanoma is a malignant tumor that originates in melanocytes. It is a highly malignant form of skin cancer, and, though rare, is responsible for the majority of skin cancer-related deaths.
甲床分離症(Onychosis)
指甲的一種疾病
Papillary 
The papillary layer is outermost and extends into the epidermis to supply it with vessels. It is composed of loosely arranged fibres. Papillary ridges make up the lines of the hands.
Recticular Layer
The reticular layer is more dense and is continuous with the hypodermis. It contains the bulk of the structures (such as sweat glands). The reticular layer is composed of irregularly arranged fibres and resists stretching.
