Involuntary reflexes

Answer 11

Sense reflexes (eg touch smell etc )

Question 12

Muscle important for reflexes

Answer 12

Skeletal

Question 13

Exercise and reflexes

Answer 13

Exercise strengthens skeletal muscle which is important for reflexes however very limited evidence that improves the reflex arc

Question 14

Obesity and reflexes

Answer 14

No direct link but it’s linked to metabolic syndrome, causes changes in adipokines and insulin. Obesity causes chronic increase in sympathetic activity.
