Anatomy Ch 4: Tissues (Mastering A&P)

What is not true of epithelial cells?

They are richly vascularized.

This primary tissue type generates electrical signals and can actively contract.

Muscle

Two of the four primary tissue types contain excitable cells, cells that receive stimuli and generate electrical signals. One of these is muscle tissue. Name the other.

Nervous

Epithelial tissues can be classified according to cell shape. __________ epithelial cells are scalelike and flattened.

Squamous

This connective tissue is made of hard calcified matrix and stores calcium and other minerals.

bone (osseous tissue)

This tough, strong, connective tissue is found beneath the epithelial tissue of the skin. It is packed with collagen fibers that run in all different directions.

dense irregular

This connective tissue is packed with parallel collagen fibers, attaches muscles to bone, and can withstand great stress when pulled in one direction.

dense regular

Exocrine glands are considered to be a type of connective tissue because ________.

exocrine glands are epithelial tissue, not connective tissue

This is the toughest kind of cartilage. It is found in places that receive a lot of mechanical stress.

fibrocartilage

All connective tissue is derived from an embryonic tissue known as __________.

mesenchyme

All the following are examples of connective tissue EXCEPT __________.

neurons

Simple epithelia have ________.

one type of epithelial cell, arranged in a single layer

Epithelial cells are specialized to ________.

secrete, filter, and absorb

This tissue can look like the hexagonal tiles of a bathroom floor. It also forms the air sacs of the lungs.

simple squamous epithelium

Which muscle tissue type is controlled voluntarily?

skeletal

This tissue type is capable of changing its shape and stretching. It lines the urinary bladder and ureters.

transitional epithelium

Endocrine and exocrine glands are classified as epithelium because they usually develop from epithelial membranes.
