Question 13

Where can we find elastic cartilage?

Answer 13

• External ear
• Epiglottis
• Eustachian tube

Question 14

Where can we find fibrocartilages?

Answer 14

• Pubic symphysis
• Knee menisci

Question 15

Smooth muscle characteristics

Answer 15

• Single central nucleus
• Not obviously striated
• Not under voluntary control
• Long slow contraction - slow to tire
• Found in: walls of the gut, urinary system, blood vessels, respiratory system, skin, endocrine system

Question 16

Striated muscles

Answer 16

• Multiple nuclei
• Striated
• Voluntary or reflex
• Fast contraction
• Found in: most muscles that move the skeleton + diaphgram + part of the esophagus

Question 17

Cardiac muscle

Answer 17

• Single central nucleus
• Cells are linked by intercalated discs - allow fast conduction
• Striated
• Not under voluntary control
• Found in: wall of the heart
