Epithelial Tissue
What epithelial tissue is one thin layer of flat cells and is found in the alveoli of the lungs?
Simple squamous
Name the four major types of connective tissue.
Proper, cartilage, bone, blood
What is the major organ of the integumentary system?
Skin
What are the four major tissue types found in the human body?
Epithelial, connective, muscle, nervous
What protein is found in both hair and nails?
Keratin
What epithelial tissue is one layer of cube-shaped cells and is commonly found in kidney tubules?
Simple cuboidal
What material surrounds the cells of connective tissue and helps give the tissue its properties?
Extracellular matrix
Name the three major regions discussed in a skin cross-section.
Epidermis, dermis, hypodermis
During passive transport, molecules generally move from what concentration to what concentration?
High to low
What area produces new cells that cause both hair and nails to grow?
Matrix
What epithelial tissue has many layers, protects against friction, and forms the epidermis?
Stratified squamous
Which major connective tissue type provides rigid structural support?
Bone
Which skin layer contains blood vessels, nerves, sweat glands, and oil glands?
Dermis
When ATP is required to move a substance across the membrane, it generally moves from what concentration to what concentration?
Low to high
What is the visible whitish part of the nail matrix called?
Lanula
What epithelial tissue changes shape when stretched and is found in the urinary bladder?
Transitional
Which connective tissue type has a liquid matrix and transports materials throughout the body?
Blood
What cells produce the pigment melanin?
Melanocytes
A response reverses a change and brings the body back toward normal. What type of feedback is this?
Negative feedback
Which gland releases sebum, an oily substance that softens and protects the skin and hair?
Sebaceous gland
This tissue looks multilayered, but every cell touches the basement membrane. It often contains cilia and goblet cells. Name it.
Pseudostratified
A tissue must cushion a joint while remaining more flexible than bone. Which major connective tissue type best fits that job?
Cartilage
Name the two forms of melanin responsible for darker and redder pigmentation.
Eumelanin + pheomelanin
A response strengthens the original stimulus instead of reversing it. What type of feedback is this?
Positive feedback
Hair has growth and rest periods, while nails continuously grow. What cellular process in the matrix produces the new cells in both structures?
Mitosis
