(b) Nervous system
(c) Skeletal system

Answer:

A baby has 300 bones, but as it grows, some of the bones fuse together. Therefore, a baby has more bones than an adult (206 bones).

Answer:

A joint is a place where two or more bones are attached together.

Answer:

There are two types of joints in our body. They are as follows:

(a) Fixed joints: Joints that don't allow the movement of bones are called fixed joints. For e.g., the joint between our teeth and jaw bone, and between the bones of cranium.
(b) Movable joints: Joints that allow the bones to ove are called movable joints. For e.g., ball-and-socket joint, hinge joints, pivot joints and gliding joints

Answer:

Tendon is a tough, elastic and cord-like tissue that attaches the muscles to the bones.

Answer:

Ligament is a tough, flexible and elastic tissue that attaches two bones.

Answer:

Hinge joint allows the bones to move in one direction only. Example: Hinge joints are present in the elbows and knees.

Answer:

An example of the pivot joint is the neck joint that allows the movement of our head.

Answer:

Snails have a large flat foot that secretes a slimy substance, thereby helping the snails to glide over the ground easily.

Answer:

The hip bone and the vertebrae join to form the pelvic girdle.

Answer:

Cartilage is a rubbery tissue which covers the surface of two bones joining each other.
It reduces the friction between the surfaces of these two bones when they move against each other.

Answer:

An insect has three pairs of jointed legs with strong muscles to pull them. The ball-and-socket joints further connect its legs to its body. Among those six legs, three support the insect's body when it walks, and the other three help it to move forward.

Answer:

Gliding joints are present between the vertebrae, and between the wrist and ankle bones. They are not movable joints, and only allow small and restricted movements like the movement of a spring.

Answer:

A pivot joint is a movable joint that allows the twisting movement of bones.
Example: The movement of our head due to the pivot joint of the neck.

Answer:

When an earthworm moves, the bristles at its rear end hold the ground firmly, while the front of its body stretches forward with the help of muscles. Then the bristles under its front end hold the ground firmly and the muscles contract, while those bristles under its rear end relax. This process is repeated by the earthworm to move forward with the help of the wave of contractions of its body muscles.

Answer:

Following are the functions of the skeletal system:

  1. It gives shape to our body.
  2. It provides support to our body.
  3. It protects our internal organs.
  4. It helps us in moving our body.

Answer:

Ball-and-socket joint:
In this joint, the round head of one bone is fitted into the hollow, cup-shaped socket of the other bone. The bone that fits into the socket is free to move in all directions about that joint. It is a mobile joint that allows the maximum freedom of movement.
Example: The joint of upper arm and the shoulder bone

Answer:

Ribcage offers a protective covering to our lungs and heart. It is formed by the ribs that curve around and join the vertebral column at the back.
Its main function is to protect the heart and lungs. Also, it expands when we inhale thereby helping us to breathe.

Answer:


The movement of our forearm is brought about by an antagonistic pair of muscles, i.e. the biceps and triceps. These muscles work in opposite directions. The contraction of biceps pulls our forearm upward, while the contraction of the triceps pulls it downward.

Answer:

The body of a fish have the following features that help it in swimming:

(a) It has a streamlined body covered with scales that helps it to overcome the resistance offered by water.
(b) It has a very flexible vertebral column that can move from side to side.
(c) It has fins that help it to turn or change course.
(d) Some of the fishes have swim bladders inside their bodies which help them to sink into the water or rise to the surface.

Answer:

Following are the features of a bird that help it to fly:

(a) It has a smooth, streamlined body that offers minimal resistance against wind.
(b) It has hollow bones that makes it lighter.
(c) It has strong flight muscles attached to its wings.
(d) It has wings that spread out and help it to fly against the force of gravity.
(e) It has air sacs in its body to provide extra oxygen required for flying.

Answer:

1. Each finger of our hands has three bones.
2. The backbone consists of small, ring-like vertebrae.
3. Animals without backbone are called invertebrates.
4. The movement of animals from one place to another is called locomotion.
5. The thigh bones fit into the sockets of the hip bones.

Bones in an adult two hundred and six
Ribs protect our heart and lungs
Vertebrae protect the spinal cord
Triceps contract to pull our arms downward
Biceps contract to pull our arms upward
Bones in a baby three hundred
