Skeletal System

Question 1

What is the major function of the skeletal system?

Answer 1

To provide form and shape to the body, thereby giving protection and support, plus allowing bodily movement.

Question 2

What does the skeletal system help produce?

Answer 2

Helps to produce blood and storing minerals for the homeostasis of the body.

Question 3

What does the skeletal system determine?

Answer 3

Our stature and the positioning of our bones determines our shape and size.

Question 4

What two parts is the skeletal system divided into?

Answer 4

The appendicular system,

the axial system

Question 5

What does the axial skeletal system consist of?

Answer 5

The skill, rib cage and our vertebral column.

Question 6

What does the appendicular skeleton include?

Answer 6

Our upper and lower extremities.

Question 7

What does bones provide protection for? What’s an example?

Answer 7

Internal organs. The ribcage protects the heart and lungs in the chest cavity.

Question 8

Is it true that nutrients and blood constituents are provided to the body from bone?

Answer 8

Yes.

Question 9

What do our bones form?

Answer 9

Junctions, which are referred to as joints.

Question 10

Our bones form junctions, referred to as joints, which are linked by ______ and they are the sites where _____.

Answer 10

Our bones form junctions, referred to as joints, which are linked by our connective tissue and muscles, and they are the sites where movement due to muscle contraction takes place.

Question 11

How many bones are there in the skeletal system? How many of them use voluntary movement?

Answer 11

206 bones total, 177 use voluntary movement.

Question 12

What two primary functions do bones provide during movement?

Answer 12

Support and leverage.

Question 13

Bones are the support system for what?

Answer 13

Soft tissues.

Question 14

Posture is an essential component of the support system provided by our bones and is ____________.

Answer 14

Essential for the allocation of resources within the body.

Question 15

With regard to leverage, our bones act like rigid levers, ____________.

Answer 15

Altering the direction and force exerted by our muscles.

Question 16

How are our joints formed?

Answer 16

Our joints are formed by one bone that articulates with another bone.

Question 17

In what ways can joints be categorized?

Answer 17

By their structure, function or movement, known as arthrokinemeatics.

Question 18

What joints are most affiliated with our body movement? How much of the body do they make up? And what do they have a large capacity for?

Answer 18

The synovial joints. These joints are held by a joint capsule and ligaments. They consist of roughly 80% of the joints within the body and have a large capacity for motion.

Question 19

During a roll movement–especially during exercise–a bone in the joints ________. Similar to the ______. What’s a good example?

Answer 19

rolls across the surface of another; similar to the tire of a motor bike that rolls down a road. A good example of this movement in our body is during a knee extension when the tibial condyles joint slides across to what is known as the femoral condyles joint.

Question 20

What are two common movements?

Answer 20

Roll movements and spin movements.

Question 21

What is a spin movement? What is it similar to? What’s an example?

Answer 21

When one joint surface rotates on another, similar to twisting a lid off a jar of spaghetti sauce. An example of this movement is when the forearm is rotated from the hand facing down to the hand facing up.

Question 22

What is the best exercise for increasing nutrition to the joints?

Answer 22

Stretching.

Question 23

What is flexibility?

Answer 23

The range of motion (ROM) available to a joint or joints.

Question 24

What does ROM stand for?

Answer 24

Range of motion.

Question 25

Increased ROM can provide what? What does this result in?

Answer 25

Greater mechanical efficiency. This efficiency results in more effective and safer movement.

Question 26

A mobile joint moves more _____________ and ____________.

Answer 26

A mobile joint moves more easily through a range of motion and it requires less energy.

Question 27

What does healthy flexibility mean?

Answer 27

The capacity to move freely in all desired directions.

Question 28

When stretching, what should the movement be restricted to?

Answer 28

The intended movement capabilities or to the joint’s functional range of motion (FROM).

Question 29

What does FROM stand for?

Answer 29

Functional range of motion.
