Spine

Question 1

the 3 sections of the spine

Answer 1

cervic, thoracic, and lumbar

Question 2

how many vertebrae does the cervical section have

Answer 2

7

Question 3

how many vertebrae does the thoracic section have?

Answer 3

12, one for each rib

Question 4

what is the main movement of the thoracic section?

Answer 4

rotation

Question 5

Describe the first vertebrae of the cervical section

Answer 5

The atlas. The atlas connects to the skull and is responsible for 50% flexion in the neck.

Question 6

Describe the second vertebrae of the cervical section

Answer 6

Axis. Attaches in the Atlas as a pivot joint and is responsible for 50% of the rotation of the cervical section

Question 7

What is the importance of the 7th Vertebrae?

Answer 7

It is the first visible vertebrae and is an important landmark because it sits right in a diamond shape in between the trapezius.

Question 8

How many Vertebrae are in the spine

Answer 8

24 total, 7 cervical , 12 in the Thoracic, and 5 in the lumbar.

Question 9

Describe the overall shape of the spine

Answer 9

The spine moves in 4 arch curve allowing for a maximum compromise between stability and flexibility.

Question 10

Describe the curve of the cervical section

Answer 10

The curve of the cervical section is forward facing and the least curvy,

Question 11

Describe the curve of the Thoracic section

Answer 11

The curve of the Thoracic section is backward facing, longest and more curvy than the cervical section, the ribcage inherits this backward lean

Question 12

Describe the curve of the Lumbar section

Answer 12

The curve of the lumbar section is Forward facing and curvier than the thoracic section. The pelvis inherits this forward lean.

Question 13

Describe the curve of the sacral section

Answer 13

The sacral curve is the most curvy.

Question 14

Describe the all movements of the neck

Answer 14

Rotation, flexion, extension, and lateral bending

Question 15

What is responsible for 50% of the flexion in the neck (nodding or looking up and down)

Answer 15

The Atlas, the first vertebrae, is responsible for 50% of the flexion in the neck.

Question 16

What is responsible for 50% of the rotation in the neck

Answer 16

The Axis, the second vertebrae, is responsible for 50% of the rotation in the neck. It fits into the Atlas to make a pivot joint.

Question 17

Which parts of the Thoracic vertebrae are visible on the surface?

Answer 17

Usually only the top and bottom Vertebrae are visible, but the are extreme cases where Thoracic and/ or lumbar vertebrae are visible.

Question 18

How do thoracic Vertebrae look on the surface

Answer 18

The Thoracic vertebrae look Pointy

Question 19

How do the lumbar Vertebrae look

Answer 19

The lumbar vertebrae look longer

Question 20

What is the main motion of the Thoracic?

Answer 20

The main motion of the Thoracic is Rotation

Question 21

What is the main motion of the Lumbar

Answer 21

The main motion of the Lumbar is flexion, but there is limited Lateral bending

Question 22

Describe the Lumbar vertebrae and what movement they allow for.

Answer 22

The top 3 Lumbar vertebrae allow for lateral bending. The bottom 2 connected strongly to the coccyx.

Question 23

What is the tailbone made up of

Answer 23

The Sacrum and the coccyx
