Questions and Answers
What are the four types of tissues?
Epithelial, muscle, connective, nervous.
What are the three types of epithelial tissue? What two forms do they come in?
Squamous, cuboidal, columnar. They come in simple (flat/one layer) or stratified (layered/complex).
What kind of cells does this epithelial tissue have? Where do the types of cells in this tissue occur? What are their function?
Stratified (layered) squamous cells. They occur at abrasions and on the skin. Their function is to protect the body.

Study Notes
Types of Tissues
- Four main types of tissues: epithelial, muscle, connective, nervous.
Epithelial Tissue
- Three types of epithelial tissue: squamous, cuboidal, columnar.
- Two forms of epithelial tissue: simple (one layer) and stratified (multiple layers).
Stratified Squamous Cells
- Composed of stratified squamous epithelial cells.
- Found in areas subject to abrasion, such as the skin, providing protection.
Columnar Cells with Villus
- Composed of columnar epithelial cells.
- Structure indicated by pointer: villus.
- Function: absorption of nutrients from food into the bloodstream.
Cuboidal Cells
- Composed of cuboidal epithelial cells.
- Function: reabsorption of nutrients to return to the blood.
Simple Columnar Cells with Cilia
- Composed of simple columnar epithelial cells.
- Function of cilia: filter air during inhalation, found in the trachea.
Smooth Muscle Tissue
- Type: smooth muscle tissue, non-striated.
- Found in: esophagus, intestines, and stomach, allowing movement of food through the digestive tract.
Cardiac Muscle Tissue
- Type: cardiac muscle tissue, striated.
- Unique structure: intercalated discs facilitating communication between cardiac cells.
Skeletal Muscle Tissue
- Type: skeletal muscle tissue, striated.
Connective Tissue
- Types of connective tissue: Proper (Loose and Dense).
- Loose connective tissue example: areolar, surrounding organs with ample ground (white) space.
- Dense connective tissue example: tendon, characterized by very little ground space.
Adipose Tissue
- Type: adipose (fat) connective tissue.
- Characterization: cells/nuclei pushed to the side.
Cartilage
- Type: cartilage connective tissue.
- Cells specific to cartilage: chondrocytes.
Bone
- Type: bone connective tissue.
- Osteon: structural unit seen in dense bone.
Blood
- Type: blood connective tissue.
- Two primary cell types: erythrocytes (red blood cells) and leukocytes (white blood cells).
- Erythrocytes distinguished by hemoglobin and lack of nuclei; leukocytes have nuclei, typically stained purple for identification under a microscope.
Nervous Tissue
- Type: nervous tissue, primarily composed of neurons.
- Other type of nervous tissue: glial cells, not visible under the microscope.
