Tissue Types

Question 1

Name the three types of Epithelial cells

Answer 1

1. Simple Squamous
2. Simple Cuboidal
3. Simple Columnar

Question 2

What are simple squamous cells?

Answer 2

A flat, epithelial cell which makes up thin membranes. Has a flat nucleus.

• It has a fast absorption and diffusion rate.
• It’s found in the alveoli of the lungs, the serous membranes and the lining of the heart and blood vessels.

Question 3

What are simple Cuboidal cells?

Answer 3

Square shaped epithelial cells that are about as tall as they are wide.

• Absorb nutrients and produce secretions (sweat)
• They are found in the Kidney tubules and ducts/secretory sections of small glands.

Question 4

What are simple Columnar cells?

Answer 4

Cylindrical epithelial cells which have a stretched, over shaped nucleus.

• Absorb nutrients and produce secretions.
• Found in The digestive tract (secretory) and the bronchi and uterine tubes.

Question 5

What does connective tissue develop from?

Answer 5

Mesenchyme

Question 6

What types of fibres are connective tissues made up of?

Answer 6

1. Collage: Dense Fibres.
2. Elastin: Elastic Fibres.
3. Reticular: Fine Fibres.

Question 7

Define Ground Substance

Answer 7

The unstructured material that fills the space between the cells and contains fibres. It’s composed of interstitial fluid, Cell adhesion proteins and proteoglycans. Acts as a molecular sieve. Ground Substance + Fibres = Extracellular Matrix.

Question 8

Name the types of Connective Tissues.

Answer 8

1. Connective Tissue Proper
   
   • Loose Connective Tissue: Areolar, Adipose and Reticular.
   • Dense Connective Tissue: Dense Regular, Irregular and Elastic.
2. Cartilage: Hyaline, Elastic and Fibrocartilage.
3. Bone: Compact and Cancellous
   4: Blood.

Question 9

Name the four basic tissue types

Answer 9

1. Epithelial Tissue: A covering tissue.
2. Connective Tissue: Supports other structures.
3. Muscular Tissue: Movement.
4. Nervous Tissue: Controlling tissue. Sends information around the body.
