Spinal Cord

Question 1

3 Functions of Vertebral Column

Answer 1

1. Houses and protects the spinal cord
2. Provides the body with some degree of axial support
3. Provides some degree of movement of the neck, thoracic region, and lumbar region

Question 2

Vertabrae

Answer 2

approximately 33 bones called this make up the vertebral column

Question 3

Corpus

Answer 3

A mass of bone, function is supporting the powerful muscles used for lifting

Question 4

Vertebral Foramen

Answer 4

The opening in the vertebrae. Directly where spinal cord passes through

Question 5

Neural Arch

Answer 5

Surrounds the vertebral foramen

Question 6

Anterior Neural Arch

Answer 6

Between the vertebral foramen and the corpus

Question 7

Posterior Neural Arch

Answer 7

Below the vertebral foramen

Question 8

Spinous Process

Answer 8

The projection extending posteriorly off the posterior arch. Serves as a point of muscle attachment

Question 9

Transverse Process

Answer 9

Projection. Located laterally at each side of vertebrae. Serves as a point of muscular attachment and the point of attachment of the ribs.

Question 10

Articular Facets

Answer 10

Each vertebrae above level of the sacrum contain two superior and 2 inferior. The superior join with the inferior of each vertabrae

Question 11

Intervertebral Foramen

Answer 11

The opening between each vertabrae above the level of the sacrum. It’s how blood vessels pass to spinal cord and how spinal nerves enter and exit the spinal cord.

Question 11

Intervertebral disc

Answer 11

Separates each vertabrae that’s above the level of the sacrum. Rings of cartilage that gives the vertebral column flexibility and resiliency. Acts like the body’s shock absorbers

Question 12

Cervical Vertabrae

Answer 12

7 most superior vertabrae. Make up the neck.

Question 13

Cervical Vertabrae Distinguishing factors

Answer 13

1. Vertebral foramen are the widest.
2. Each transverse process has an opening through it called the transverse foramen

Question 14

Transverse Foramen

Answer 14

Allows for passage of blood vessels and nerves

Question 15

C1 Name and Function

Answer 15

Called the Atlas. Where the skull fits into superior facets

Question 16

C2 Name and Function

Answer 16

Called the Axis. It’s an anterior projection that projects superiorly through atlas. It’s a dens, so serves as a pivot point for your skull

Question 17

Dens

Answer 17

Serves as a pivot point for your skull????

Question 18

Thoracic Vertabrae

Answer 18

12 vertabrae inferior to the cervical vertabrae.

Question 19

Thoracic Vertabrae Distinguishing Factors

Answer 19

Have costal facets, or called demifacets. 3 on each side and are where the ribs are located

Question 20

Lumbar Vertabrae

Answer 20

5 vertabrae that are inferior to the thoracic vertabrae.

Question 21

Lumber Vertabrae Distinguishing Factors

Answer 21

The largest vertabrae. Have a large spinous process. Where the muscles of the lower back attach

Question 22

Sacral Vertabrae

Answer 22

5 vertabrae that are inferior to lumber vertabrae. They are separated when we’re born but as we age, they fuse to create the sacrum.

Question 22

Coccygeal Vertabrae

Answer 22

About 3-5 vertabrae at birth and are located inferior to sacrum. In the first few years, they fuse to create the coccyx.

Question 23

Coccyx Function

Answer 23

A vestigial structure (Has no function)
