Summary Introduction

Introduction: A skeletal system is essential for the body support and to protect the internal organs of the body. Our body movements are brought about by the muscles by its interaction with the skeleton. The skeletal system is mainly classified into three- hydrostatic skeleton, endoskeleton and exoskeleton.

Answer to Problem 1SQ

Correct answer: An endoskeleton consists of internal hard parts.

Hence, the correct answer is option c.

Explanation of Solution

Reason for the correct answer:

One of the main types of skeleton is the endoskeleton. Endoskeleton is a structural support found internally within an animal’s body. In humans, the endoskeleton is made up of framework of cartilages and bones. Another example- the sea stars are the echinoderms that contain the endoskeleton which is made up of hard, calcium-rich plates.

Option c. is given as “internal hard parts”.

An internal structural support found inside an animal made up of hard and tough mineralized tissue is termed as endoskeleton. Tissues present in the endoskeletons facilitate the movement by attaching to the muscles.

Hence, the correct answer is option c.

Reasons for the incorrect answers:

Option a. is given as “a fluid in an internal space”.

A fluid-filled internal space that obtains the energy for the contraction of muscles is known as hydrostatic skeleton. It does not contain the internal hard parts.

Hence, option a. is incorrect.

Option b. is given as “hardened plates at the surface of a body”.

This is incorrect because the structural support or the hardened plates that are found externally to support the outer surface of the body is called as exoskeleton. This is different from the endoskeleton.

Hence, option b. is incorrect.

Option d. is given as “a fluid that surrounds the body”.

This is incorrect because interstitial fluids or tissue fluids are the fluid that surrounds the body or are present between cell, blood vessels, and the lymph vessels. These fluids help to supply essential nutrients as well as removing the harmful substances from the spaces.

Hence, option d. is incorrect.

Hence the options a., b., and d. are incorrect.

Conclusion
An endoskeleton is essential to protect the internal organs of the body
