NCERT Solutions for Class 6 Science Chapter 5: Body Movements

The “Body Movements” chapter in your 6th-grade science book focuses on the amazing ability of humans and animals to move their bodies.

1. The Skeletal System:

  • The skeleton is a framework of bones that provides support, shape, and protection to the body.
  • Joints connect various bones, allowing for movement at different points in the body.
  • There are different types of joints, such as hinge joints (elbows, knees) that allow bending and straightening, and ball-and-socket joints (shoulders, hips) that allow for wider movement range.

2. The Muscular System:

  • Muscles are tissues that contract and relax, causing movement in the body.
  • Muscles are attached to bones at tendons and work in pairs (antagonist and agonist) to produce movement.
  • Voluntary muscles are controlled consciously (e.g., moving your arm), while involuntary muscles function automatically (e.g., breathing).

3. The Nervous System:

  • The nervous system plays a crucial role in coordinating and controlling body movements.
  • The brain sends signals through nerves to the muscles, directing their contraction and relaxation.

4. Importance of Movement:

  • Body movements are essential for various daily activities like walking, running, jumping, and grasping objects.
  • Exercise strengthens muscles and bones, improves flexibility, and maintains overall health and well-being.

Ans : 

Column IColumn II

FishHave fins on the body,Have a streamlined body 
RibsProtect the heart , 
SnailShows very slow movement
CockroachHas an outer skeleton,Can fly in hair

4. Answer the following:

(a) What is a ball and socket joint?

Ans : A ball and socket joint is a type of movable joint found in the human body that allows for a wide range of movement in multiple directions.

(b) Which of the skull bones are movable?

Ans : The Mandible or lower jaw.

The mandible connects to the temporal bone of the skull at the temporomandibular joint (TMJ), which allows for up-and-down movement of the jaw.

(c) Why can our elbow not move backwards?

Ans : Our elbow cannot move backward because it is a hinge joint. Hinge joints, like the door hinge they are named after, allow movement in only one direction: flexion and extension. Flexion is bending the joint, like bringing your hand towards your shoulder. Extension is straightening the joint, like pushing your arm straight out.
