VETEBRAL COLUMN

Question 1

Regardless of individual’s body weight, the adult vertebrae measures approximately ________. It extend from the base of the skull to the tail bone

Answer 1

60-70cm in length (18-28 inches”).

Question 2

remain as separate bones during life and are called ” TRUE
VERTEBRAE”
and is a movable vertebrae

Answer 2

24 Vertebrates

Question 3

remaining are called
“FALSE VERTEBRAE” as they become
fused to form one segment of the
vertebrae, they are the Sacrum &
Coccyx and is considered as “fixed
vertebrae”. The vertebrae are named
and are numbered regionally from
above downward.

Answer 3

9 Vertebrates

Question 4

DIVISIONS OF THE VERTEBRAL COLUMN.

Answer 4

1. Cervical spine – 7
2. Thoracic/Dorsal spine – 12
3. Lumbar spine – 5
4. Sacrum - 5 (fused)
5. Coccyx – 4-5 incomplete

Question 5

• The Cervical vertebrae form a forward curve called a

Answer 5

lordotic curve

Question 6

• The Thoracic vertebrae form a curve backward called a

Answer 6

“Kyphotic curve.

Question 7

• The Lumbar vertebrae form a forward curve like the cervical called the

Answer 7

”Lordotic curve”

Question 8

• An exaggerated thoracic curve is called ”.

Answer 8

“Kyphosis” or Hunchback

Question 9

• An exaggerated lumbar curve is called

Answer 9

“Lordosis” or “Swayback

Question 10

• An appreciable lateral deviation of the normal alignment of the vertebral column is called

Answer 10

Scoliosis

Question 11

• A combined lateral (scoliosis) and posterior (kyphosis) curvature of the spine is called

Answer 11

”Scoliokyphosis” or “Kyphoscoliosis”.

Question 12

A typical vertebra has a

Answer 12

body
neural arch
pedicles
laminae or plates,
vertebral foramen and processes.

Question 13

– is the solid anterior part, shaped like a cylinder with flat posterior surface.

Answer 13

Body of vertebra/Centrum

Question 14

– are thick rounded extensions passing back, one on each lateral border of the flattened posterior surface of the body.

Answer 14

Pedicles or Root

Question 15

– are two flattened plates of bone one passing towards the midline from the posterior end of each pedicle. These unite in the midline behind to form the spinous process and complete the arch.

Answer 15

Two Laminae or Plates

Question 16

– is the opening behind the body, enclosed by the arch. Along with similar openings in the other vertebrae, it forms a canal for the spinal cord.

Answer 16

Vertebral Foramen

Question 17

– are formed by the curved upper and lower border of the pedicles.

Answer 17

Vertebral Notches

Question 18

A similar curved of the pedicle above or below, complete an opening called the

Answer 18

“intervertebral foramen”.

Question 19

– are two bones, one on each side, extending laterally from the junction of the pedicle and lamina.

Answer 19

Transverse Processes (2)

Question 20

• project upwards towards the head from the bases of the transverse processes.

Answer 20

Superior Articular Processes (2)

Question 21

– projects downward from the bases of the transverse processes.

Answer 21

Inferior Articular Processes (2)

Question 22

– extend posteriorly or back from the posterior border of the vertebral arch, at the junction of the two laminae.

Answer 22

Spinous Process

Question 23

– “par” for short is that part of the vertebra located between the inferior and superior articular processes. This corresponds as an imaginary line that represent the neck of the “scotty dog” sign.

Answer 23

Pars Interarticularis
