Four Main Tissue Types
This tissue type covers surfaces and lines body cavities, such as skin and the stomach lining.
What is epithelial tissue?
These young cells in the womb have unlimited potential to become any tissue type.
What are embryonic stem cells?
The tough outer layer of skin made of dead cells that constantly shed and renew.
What is the epidermis?
Diseases caused by microorganisms such as bacteria, viruses, and fungi.
What are infectious diseases?
The study of how normal body functions become abnormal is called this.
What is pathophysiology?
This tissue type supports and connects the body and includes bones, blood, and fat.
What is connective tissue?
These cells, present throughout life, help repair and replace damaged tissues.
What are adult stem cells?
The living inner layer of skin packed with blood vessels, nerves, and glands.
What is the dermis?
Diseases in which tissues break down, such as muscular dystrophy or osteoporosis.
What are degenerative diseases?
Factors that increase susceptibility to disease, such as age, heredity, or lifestyle.
What are predisposing causes?
This tissue type carries electrical signals and makes up the brain, spinal cord, and nerves.
What is nervous tissue?
Tissues like the brain and heart have very few of these, so they repair slowly or not at all.
What are stem cells?
The deepest fat layer that insulates the body and stores energy.
What is the subcutaneous layer (or hypodermis)?
Disorders caused by too little or too much of essential nutrients.
What are nutritional disorders?
The science that studies how diseases spread in populations.
What is epidemiology?
This tissue type contracts to produce movement, including the heart beating and walking.
What is muscle tissue?
This organ has moderate stem cells and can regenerate completely after damage.
What is the liver?
The protein that makes skin tough, waterproof, and helps it renew itself.
What is keratin?
“New growths” that include both cancerous and non-cancerous tumors.
What are neoplasms?
Paul’s painless pink nodule with a pearly border was a common site for this type of cancer.
What is skin cancer (or basal cell carcinoma)?
The thin epithelial residue that sometimes forms on newly erupted teeth.
What is Nasmyth’s membrane?
Skin and the digestive tract repair quickly because they have many of these.
What are stem cells?
The entire renewal cycle of the epidermis takes about this many days.
What is 28 days?
Mental health conditions affecting thoughts, emotions, and behaviors.
What are psychiatric disorders?
The body’s largest organ and first line of defense against infection and fluid loss.
What is the skin (or integumentary system)?
