Skeletal System Flashcards

1
Q

How does the skeletal system create movement?

A

The skeleton provides an anchor point for the muscles to attach to.
Tendons join muscles to bones.
When bones meet they create a joint, this helps to create movement.

Q

How is the skeletal system used for mineral storage?

A

The bones store minerals such as calcium and phosphorus and they are released into the blood stream. This helps maintain health.

Q

How does the skeletal system provide protection?

A

Flat bones protects the vital organs to help prevent impact and injury whilst playing sport. For example, heading a football the cranium protects the brain.

Q

How does the skeletal system provide support?

A

The bones are solid and rigid.
They keep us upright and hold the muscles and organs in place.

Q

How do bones produce blood cells?

A

The inner marrow of long bones produces red and white blood cells.
Red blood cells carry oxygen to the muscles.
White blood cells help fight against infections.

Q

What are synovial joints?

A

They are specifically designed to allow movement and prevent injury.
Two main types are ball and socket and hinge joints.
They consist of the bone, cartilage, tendon, muscle, bursae, ligament.

Q

What movements does a ball and socket joint do?

A

Flexion- decrease of angle
Extension- increase of angle
Abduction- movement of a limb away from the midline of the body.
Adduction- movement of a limb towards midline of the body.
Circumduction- circular movement around the joint.
Rotation- turning around an axis/ fixed point.

What is adduction and abduction?

A

-Adduction is the movement towards the midline of the body
-Abduction is the movement away from the midline of the body

29
Q

What is circumduction?

A

Circular movement around the joint

30
Q

What is Flexsion?

A

Angle of the joint is decreasing

31
Q

What is extension?

A

Angle of joint is increasing

32
Q

What is rotation?

A

Turning around an axis/ fixed point

33
Q

What is Dorsiflexsion?

A

Angle of the joint decreasing at the ankle

34
Q

What is plantarflexsion?

A

Angle of the joint increasing at the ankle

35
Q

What are hinge joints?

A

Allow the body to move forward and backwards but not side to side

36
Q

What are ball and socket joints?

A

The rounded end of one bone fits inside a cup shaped ending on another bone

37
Q

What are synovial joints?

A

A freely moveable joint that are the most common in the body, made to help prevent injury

38
Q

What are the functions of the skeletal system?

A

-movement
-mineral storage
-protection
-support
-production of red blood cells
-shape

39
Q

What is movement in the skeletal system?

A

A place for muscles to attach to, when the muscles contracts they pull tendons which are attached to bones.

40
Q

What is mineral storage in the skeletal system?

A

Bones store several minerals including calcium and phosphorus which are released into the blood when needed to maintain health

41
Q

What is protection in the skeletal system?

A

Flat bones protect vital organs from impact and injury’s when play for example sport

42
Q

What is support in the skeletal system?

A

The bones are solid and rigid so they help us keep upright and hold the muscles and organs in place

43
Q

What is the production on red blood cells in the skeletal system?

A

The inner marrow of the Long bones produces a red and white blood cell
Red blood cells carry oxygen to muscles
White blood cells help fight infection and help maintain good health

44
Q

What is shape in the skeletal system?

A

The taller people have longer leg bones and larger vertebrae
The skeletal also provides points for muscles to attach to
