Unit 3 Lesson 4: Bodies in Motion

Question 1

Any health science career you choose will require you to be knowledgeable regarding how humans…

Answer 1

move

Question 2

In what ways is movement good for health

Answer 2

Movement is good for health, increasing blood circulation, stimulating digestion, and helping toxins to move out of your body.

Question 3

Why is learning how the body moves so important

Answer 3

Learning how a healthy body moves can help you understand patients; it is also crucial to a career in health. After all, health workers need to know how to appropriately use their own bodies to avoid injuries.

Question 4

How does gravity affect movement

Answer 4

There are forces from outside the body that influence movement, such as the gravity that pulls everything and everybody down towards the center of the earth. Gravity also keeps us from floating around and is therefore a basic force that affects all the movement that our bodies can perform.

Question 5

What is Biomechanics

Answer 5

Biomechanics is the study of the function and structure of movement of the body, specifically how the laws of mechanics apply.

Question 6

What is kinesiology

Answer 6

Kinesiology is the study of body movement including how muscles, bones, tendons, and ligaments work together to produce movement.

Question 7

What casues movement

Answer 7

force

Question 8

What has the be present to start movement

Answer 8

There needs to be some energy that starts a movement; in other words, one object must act on another.

Question 9

What are external forces on the body

Answer 9

External forces on the body include gravity, weight, and friction.

Question 10

What are internal forces on the body

Answer 10

Internal forces that can move the body are muscles contracting, ligaments restraining movement, and the bones supporting the body.

Question 11

In body movement give an example of a force

Answer 11

. In body movement, force can be a push, which creates compression, or a pull, which creates tension.

Question 12

What factors produce a roatation

Answer 12

There can be two or more forces acting to produce rotation, or torque, causing a body part to turn rather than move in a straight line.

Question 13

how do muscles influence a body part to move

Answer 13

To move the body, a muscle influences a body part to move. Often, one muscle will pull, while a muscle on the opposite part of the body will relax.

Question 14

How do you reverse the muslce movement

Answer 14

To reverse that type of movement, the muscles will switch places: the first one will relax and the other will then contract to move that body part

Question 15

Example of muscle movemtn using the arm

Answer 15

Start with a straight arm and bend it at the elbow so your hand touches your shoulder. Then straighten your arm again. You just used two sets of opposing muscles. The bones of your upper and lower arm kept those parts straight, while the force of the muscles moved the lower arm at the elbow joint. The ligaments offered restraint so that your arm did not move past straight.

Question 16

What effect do bones have on the movment of the arm

Answer 16

The bones of your upper and lower arm kept those parts straight, while the force of the muscles moved the lower arm at the elbow joint.

Question 17

What effect do ligaments have on the movment of the arm

Answer 17

The ligaments offered restraint so that your arm did not move past straight.

Question 18

What are the 3 internal forces the made movement possible:

Answer 18

muscles, bones, and ligaments.

Question 19

To be able to describe movement, what do we need to know

Answer 19

To be able to describe movement, we need to know what part is moving, the plane, type, and direction of the movement.

Question 20
