Skeleton

Question 1

What are the three types of skeletons?

Answer 1

Hydrostatic;
Endoskeleton;
Exoskeleton

Question 2

What is a hydrostatic skeleton?

Answer 2

A skeleton that is supported by liquid pressure.

Question 3

What is an endoskeleton?

Answer 3

This is an internal skeleton.

Question 4

What is an exoskeleton?

Answer 4

Tough, external skeleton found in some invertebrate animals.

Question 5

What are some examples of hydrostatic skeleton animals?

Answer 5

Jellyfish (supported by water outside their bodies), earthworm (supported by water inside their bodies).

Question 6

What is an example of an endoskeleton?

Answer 6

Vertebrate animals like humans.

Question 7

What is an example of exoskeletons?

Answer 7

Lobsters, crabs.

Question 8

What is the best type of skeleton for protection?

Answer 8

Animals with exoskeletons are well-protected overall.

Question 9

Why are animals with exoskeletons vulnerable to predators?

Answer 9

Exoskeletons are like armoured overcoats.

As the animal grows, it needs to replace its exoskeleton by shedding its protective outercoat and a new larger skeleton takes its place.

The new skeleton is soft to start off with and hardens overtime.

This that makes these animals susceptible to predators during the time period of shedding their exoskeleton and the hardening of the new one.

Question 10

What is the human skeleton?

Answer 10

A flexible, inner framework made up of 206 bones and cartilage.

Question 11

What would we appear as without skeletons?

Answer 11

Shapeless blobs.

Question 12

How many bones does the human skeleton have?

Answer 12

206.

Question 13

What are the functions of the skeleton?

Answer 13

Shape and support, movement, protects vital organs, and blood production.

Question 14

Explain the shape and support function of the skeleton.

Answer 14

The skeleton forms the frame to which our muscles can attach and allows the body to stay upright.

Question 15

What’s an example of the shape and support function of the skeleton?

Answer 15

The backbone enables us to stay upright.

Question 16

What is the Movement function of the skeleton?

Answer 16

Muscles are attached to the skeleton. Movement occurs when the muscles pull and contract on the bones, making them move about a joint.

Question 17

What is an example of the movement function in the skeleton?

Answer 17

Bicep muscle connects to the shoulder and elbow and helps with lifting.

Question 18

What is the protects vital organs function in the skeleton?

Answer 18

Internal organs are soft and delicate and can be easily damaged. These vital organs are protected by the skeleton.

Question 19

Example of protects vital organs function in the skeleton.

Answer 19

The skull protects brain and eyes.

The ribs protect the heart and lungs.

Question 20

What is the blood production function of the skeleton?

Answer 20

The centre of some large bones contains red blood marrow, which creates red blood cells. Bone marrow also stores minerals such as calcium and phosphorous, and releases them into the blood.

Question 21

Example of blood production in the skeleton?

Answer 21

The pelvis and the femur are both important in blood production.

Question 22

What is the cranium?

Answer 22

Bones of the skull that enclose and protect the brain and organs responsible for hearing, sight, and balance.

Question 23

What is the clavicular/ collarbone?

Answer 23

Supports the upper arm and scapula.

Question 24

What is the scapula?

Answer 24

The moveable bone to which most of the shoulder muscles are attached.

Question 25

What is the sternum?

Answer 25

A flat and important bon due to its location, protecting vital organs such as the heart, lungs, and air passages.

Question 26

What is the humerus?

Answer 26

Serves as the connection between the scapular and the elbow, linking the two lower arm bones.

Question 27

What is the ribcage?

Answer 27

Protects the internal organs from damage, particularly the heart and the lungs.

Also helps you to breathe because it expands and contracts.

Question 28

What is the vertebral column?

Answer 28

Support for the body’s frame and keeps it standing upright.

Connects the head to the rest of the body.

Serves as protection for the spinal cord.

Question 29

What is the pelvis?

Answer 29

Structure that provides a foundation for the legs and also supports a portion of the abdominal and pelvic cavities.

Question 30

Radius?

Answer 30

The shorter of the two long bones of the lower arm that extends from the elbow to the wrist. It is the bone on the thumb side of the arm. It plays a huge role in the motion and stability of the arm.

Ex: wrist mobility.

Question 31

What is the ulna?

Answer 31

Located in the lower arm.

The functions of the ulna include supporting movement of the hands and arms.

Question 32

What is the femur?

Answer 32

The thigh bone, and the longest, heaviest, and strongest bone in the entire human body.

All of the body’s weight is supported by the femur during many activities such as running, jumping, walking, and standing.

Question 33

What is the patella?

Answer 33

Lies in front of the “knee join” between the femur and tibia. Its function is to protect the knee joint.

Question 34

What is the fibula?

Answer 34

An attachment point for muscles, located to the side of the tibia.

Question 35

What is the tibia?

Answer 35

Bone in the lower leg that connects to the fibula and provides movement of the legs. The main job of the tibia is to form a hinge joint with the femur that allows you to walk, run, kick a ball, and generally, have fun.
