Module 2 Powerpoint Chapter 4-5

What are the four main kinds of tissues in the human body?

Epithelial, Connective, Muscle, and Nervous tissue.

What is the primary feature of epithelial tissue?

It covers the body and lines body cavities with cells packed closely together and no blood vessels.

How are epithelial tissues classified by shape?

Squamous, Cuboidal, Columnar, and Transitional.

What is simple squamous epithelium?

A single layer of scalelike cells primarily involved in absorption.

What is the function of stratified squamous epithelium?

Protection, as it consists of several layers of closely packed cells.

What type of tissue has the most varied forms and is widely distributed in the body?

Connective tissue.

What are the primary functions of adipose tissue?

Lipid storage and providing insulation.

What are the three types of muscle tissue?

Skeletal, Cardiac, and Smooth muscle tissue.

How do neurons communicate impulses?

Through axons and dendrites.

What is the primary role of connective tissue?

To help keep the organs of the body together and give them shape.

What happens to damaged tissues during regeneration?

Phagocytic cells remove dead cells, and new tissue cells fill in gaps; sometimes replaced by scar tissue.

Define keloid.

An overgrowth of scar tissue that forms at the site of a skin injury.

What is significant about simple columnar epithelium?

It contains goblet cells and is specialized for absorption.

What differentiates cardiac muscle tissue from skeletal muscle tissue?

Cardiac muscle is involuntary and striated, while skeletal muscle is voluntary.

What type of connective tissue provides smooth surfaces for movement in joints?

Hyaline cartilage.

What kind of epithelial tissue is adapted to stretch?

Stratified transitional epithelium.
