NCERT Solutions for Class 11 Biology Chapter 20: Points To Remember

We have summarised a few important points from the entire chapter for students to refer to while studying.

  • The movements of an animal resulting in a change of location or place are called locomotion.
  • Amoeboid motion helps in the ingestion of food and locomotion as well.
  • Ciliary movements of cells lining the trachea of humans help to remove the invading microbes and dust particles.
  •  Based on their location, in humans, muscles are broadly classified into three categories: skeletal muscles, smooth muscles and cardiac muscles.
  • Cardiac muscles are also striated, but these muscles are branched and involuntary.
  • A motor neuron carries the signal to the muscle fibre, which generates an action potential in it.
  • Skeletal muscle consists of numerous physiological units called myofibrils.
