A
It provides protection to delicate organs like brain, spinal cord and lungs.

B
The bone marrow serves as the centre for the production of calcium and phosphate.

C
The movements of the ribs and sternum help with breathing.

D
In the ear, the sound vibrations are conveyed by a set of three bones as in man.
Question 2
1 / -0

Question 3
1 / -0

Various movements like looping, somersaulting, climbing, shortening and elongation can be seen in

A
starfishes

B
hydra

C
leeches

D
human beings
Question 4
1 / -0

The correct organisation of skeletal muscle is

A
fascicles → muscle fibres → myofilaments → sarcomere

B
muscle bundles → myofibrils → muscle cells → sarcomere

C
muscle bundles → muscle cells → muscle fibres → sarcomere

D
fascia → muscle cells → myofibrils → sarcomere

Solution

Each organised skeletal muscle in our body is made of a number of muscle bundles or fascicles held together by a common collagenous connective tissue layer called fascia. Each muscle bundle contains a number of muscle fibres. A characteristic feature of the muscle fibre is the presence of a large number of parallelly arranged filaments in the sarcoplasm called myofilaments or myofibrils. The portion of the myofibril between two successive ‘Z’ lines is considered as the functional unit of contraction and is called a sarcomere.
Question 5
1 / -0

Read the following statements about muscle contraction in humans :

i. chemical energy is converted into mechanical energy during muscle contraction and the chemical is a neurotransmitter.

ii. a neurotransmitter acetylcholine at motor end plate converts electrical energy into mechanical energy.

iii. in a contracted muscle, volume remains the same.

iv. a contracted muscle becomes shorter and thicker.

A
only iv) is correct.

B
only i), iii) and iv) are correct.

C
onlyi) and iv) are correct.

D
only ii), iii) and iv) are correct.

Solution

The chemical energy is converted into mechanical energy during muscle contraction and the chemical is a neurotransmitter. In a contracted muscle, volume remains the same and a contracted muscle becomes shorter and thicker.
Question 6
1 / -0

Muscles are attached to bones via :

A
Screw

B
Joints

C
Ligament

D
tendon

Solution

Muscles are attached to bones by tendon and bones are attached with another bone by ligaments. Tendon and ligaments are types of connective tissue.
Question 7
1 / -0

A
Ball and sock

B
Hinge joint

C
Pivot joint

D
Saddle joint
Question 8
1 / -0

Bones that form pelvic girdle are

A
radius - ulna

B
tibia - fibula

C
ilium - ischium - pubis

D
clavicle - scapula
Question 9
1 / -0

The pea-shaped bone in the wrist is

A
triquetral bone

B
pisiform

C
lunate bone

D
trapezoid bone
Question 10
1 / -0

The following question has four choices, out of which ONLY ONE is correct.

The layers of flat broad tendons are known as
