Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • A skeleton is the hard structure that protects the internal organs of a living thing. 
  • Skeletons can be inside the body or outside the body. 
  • In mammals, which include humans, the skeleton is made of bones. 
  • All the bones, when they are joined together, make the "skeletal system" of a body. Hence, the major constituent of the human body is a skeleton.
So, the correct answer is 'skeleton'.

Which is not the function of bones?

  1. Protection of vital organs

  2. Haemopoiesis

  3. Muscle attachment

  4. Secretion of hormones
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The endocrine glands in the body such as a pituitary gland, thymus, thyroid gland, parathyroid and etc secrete various hormones in the body. The bones cannot secrete hormones as they lack glands to produce and secrete hormones. It helps in protection of vital organs, haemopoiesis, and muscle attachment.

So, the correct answer is 'Secretion of hormones'.

The function of skeleton in the vertebrates is/are

  1. Support

  2. Hearing

  3. Sound production

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The skeleton is the structural framework of the body. Our skeleton system contains 206 bones. Its main function is to support muscles and tissues. It also protects the vital organs, allows movement of bones and muscles and serves as the storage house for immature blood cells and minerals.

So, the correct option is A.

Innominate is

  1. A nerve and an artery

  2. A nerve and a vein

  3. A vein and an artery

  4. A part of skeleton and an artery
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Term innominate is used both in the context of a skeletal system and circulatory system. In the circulatory system, innominate is one of the branches of the aortic arch. The arch of the aorta, located immediately beyond the ascending aorta, gives off three large branches.
1. The brachiocephalic trunk is a short artery formerly called the innominate. Its name means that is supplies the head and the arm. After extending upward somewhat less than 5 cm (2 inches), it divides into the right subclavian artery, which supplies the right side of the head and the neck. 
2. The left common carotid artery extends upward from the highest part of the aortic arch. It supplies the left side of the neck and the head.
3. The left subclavian artery extends under the left collar bone (clavicle) and supplies the left upper extremity. This is the last branch of the aortic arch.
Innominate bone in anatomy refers to either of the two bones that form the sides of the pelvis, consisting of three fused components, the ilium, ischium, and pubis. The non-technical name is hip bone.

A snail moves with the help of its

  1. Shell

  2. Wings

  3. Bristle

  4. Feet
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A snail uses its single long, muscular foot to crawl on a layer of mucus-like slime that it secretes. This mucus has unusual physical properties and scientists assumed that these sticky properties were essential for snail movement. 

Therefore, the correct answer is option D.

Skeleton is the site of

  1. Regulation

  2. Haemoglobin

  3. Haematopoiesis

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • The skeleton is the site of haematopoiesis, the development of blood cells that takes place in the bone marrow. 
  • In children, haematopoiesis occurs primarily in the marrow of the long bones such as the femur and tibia. 
  • In adults, it occurs mainly in the pelvis, cranium, vertebrae, and sternum. Hence, the Skeleton is the site of Haematopoiesis.
So, the correct answer is 'Haematopoiesis'.

Sesamoid bones are commonly found in ______________.  

  1. Vertebral column

  2. Ribs

  3. Skull

D Correct answer
Explanation

Sesamoid bones develop in some tendons in locations where there is considerable friction, tension and physical stress. They are typically found in palm of hands and soles of feet. Therefore, (d) is the correct answer.
