Weightage: what the paper actually did

Locomotion and Movement carried 7 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Real questions NTA asked from Locomotion and Movement, with the answer and the working. Try before you peek.

Question 1 · NEET 2026

Muscle contraction is initiated by a signal sent by the central nervous system by the release of _____ .
  1. A.acetylcholine
  2. B.acetyl coenzyme A
  3. C.cyclic guanosine monophosphate
  4. D.cyclic adenosine monophosphate
Answer and explanation

Answer: A

A motor neuron releases acetylcholine (ACh) at the neuromuscular junction. Acetylcholine binds to receptors on the muscle fibre membrane and generates an action potential. The action potential spreads along the sarcolemma and through the T-tubules, triggering the release of Ca2^{2}+^{+} from the sarcoplasmic reticulum. Calcium then initiates the interaction between actin and myosin, leading to muscle contraction.

Question 2 · NEET 2026

Which of the following represents the correct sequence of arrangement of bones in the lower limb of humans?
  1. A.Femur-tibia-patella-tarsal
  2. B.Patella-femur-tibia-tarsal
  3. C.Femur-patella-tibia-tarsal
  4. D.Femur-tarsal-patella-tibia
Answer and explanation

Answer: C

Working downward from the hip: the femur is the thigh bone, the patella is the kneecap covering the knee joint, the tibia and fibula form the leg below the knee, and the tarsals make up the ankle. The sequence femur-patella-tibia-tarsal follows that anatomical order. NCERT Class 11, Locomotion and Movement.

How to practise Locomotion and Movement

Chapter by chapter, against real past-paper questions, on a screen: NEET is computer based from 2027. Read the chapter once, then attempt its PYQs until your accuracy stops climbing, and let the wrong answers tell you which lines to reread. If the chapter keeps refusing to stick, that has its own guide. There is also a free NEET mini mock with answers.
