Week 1 Anatomy - 4 categories of cells

Question 1

What are the four broad categories of cells?

Answer 1

• Neurons
• Muscles
• Epithelia
• Connective tissue (support cells)

Question 2

What are the types of muscle cells and the function/ organ and systems

Answer 2

• Smooth, skeletal and cardiac
• Function: to contract and generate force and movement
• Organ/systems: voluntary skeletal muscles, cardia muscles, smooth muscles (bladder, bv)

Question 3

What are the sides of the epithelium and their function and organ/systens?

Answer 3

• surface side of cells (apical membrane)
• blood side of cells (basolateral membrane)
• Function: Acts as a protective barrier for organs and regulates movement of substances
• Organ/systems: skin, lining of body systems, kidney, stomach

Question 4

Classify epithelial tissue by shape and arrangement

Answer 4

Shape: squamous, cubodial, columnar
Arrangement: simple, stratified, pseudostratified

Question 5

Answer 5
