Question 11

A typical veterbrae has 7 consistent features, what are they? And what do they do?

Answer 11

Body-weight bearing
Arch - includes pedicels, laminae and transverse processes (lateral extensions
Vertebral foramen - formed from the arch, contains the spinal cord and meninges
Articular facets - (two superior and two inferior) aid in the attachment of the veterbrae
Spinous process - prosterior projection from where laminae connect
Veterbral notches - form intervertebral foramina
Intervertebral foramina - passage for spinal nerves and vessels

Question 12

What is the transverse foramina?

Answer 12

It is on the cervical vertebrae and transmit vertebral vessels to get more blood to the brain

Question 13

Which veterbrae don’t have fibrocaryilaginous intertribal discs?

Answer 13

Inbetween atlas and axis, sacral and coccyx

Question 14

What is scoliosis?

Answer 14

Is t an accentuated lateral and rotational curve of the thoracic and lumbar spine

Question 15

What is accentuated kyphosis?

Answer 15

it is an accentuation of the thoracic spine - also called hunchback

Question 16

what is accentuated lordosis?

Answer 16

-accentuation o the lumbar spine, it is called swayback - usually from weakened trunk muscles, obesity or pregnancy

Question 17

What is the atlas like?

Answer 17

ring-like structure
no body
no spinous process
no intervertebral disc
rotates on the articular facets of the axis
two lateral masses with facets to hold the occipital condyle
foramen transversarium for extra blood vessels to the brain
has an anterior arch to hold the dens of the axis
has a transverse ligament of the anterior arch to hold the dens of the axis in place

Question 18

What is the axis like?

Answer 18

supports the atlas through the superior projection of the dens
it is the strongest cervical vertebrae

Question 19

What are C3 - C7 vertebrae like?

Answer 19

• large triangular vertebral foramen
• foramen transversarium - for extra arteries
• narrow intervertebral foramina
• C3 - C5 have bifid spinous process
• C6 - C7 have long spinous process

Question 20

What is C7 vertebrae called?

Answer 20

veterbra prominens

Question 21

What are 4 key features of the thoracic vertebrae?

Answer 21

heart-shaped body with facets for rib articulation
small circular vetebral foramen
long tranverse processes, which have the costal facets for the ribs
long spinous process which clops posteriorly and overlap the next vertebrae

Question 22

What are 4 key features of the lumbar vertebrae?

Answer 22

kidney shaped body, massive for support
midsized triangular vertebral oramen
facets face medial or lateral direction, which permit good flexion and extension
spinous process is short
L5 is largest vertebra

Question 23

What are features of the sacrum?

Answer 23

it is a fusion of 5 sacral veterbrae
includes an sacral canal and the distal entry is called the sacral hiatus
the sides are called ala

Question 24

The distal end of the sacrum is called?

Answer 24

the apex

Question 25

What is the purpose of the tuberosity of the anterior of the sacrum?

Answer 25

to match with the tuberosity of the illeum to make it more secure

Question 26

Which sacral vertebra doesn’t have a tranverse process foramina?

Answer 26

S5
