Question 1

What are the corneal planes?

Answer 1

The cut the body in half vertically, separating anterior and posterior

Question 2

Define the sagittal planes.

Answer 2

A divider similar to the corneal plane, separating the body into medial and lateral. It divides the body into left and right.

Question 3

Define the transverse or axial planes.

Answer 3

It divides the body into superior (top) and inferior (bottom) portions

Question 4

Define distal

Answer 4

With distance or farther away from a midpoint

Question 5

Define proximal

Answer 5

Closer to something, or nearer to the center of something

Question 6

Define ventral

Answer 6

Ventral is in reference to anterior, or the front

Question 7

Define dorsal

Answer 7

Dorsal is in reference to something posterior, or the back/behind.

Question 8

What is the ‘weight’ of an image scan?

Answer 8

Essentially the properties of protons. By changing pulse sequencing in imaging technology and changing the properties of protons through injections of substances, different weights can be obtained.

Question 9

A T-1 weighted image will best show what?

Answer 9

Fat, fat will be bright in a T-1 image and fluid parts will be darker

Question 10

A T-2 weighted image will best show what?

Answer 10

Fluid, fluid will be brighter than fat in a T2 weighted image

Question 11

Gamma ray imaging is often used for?

Answer 11

Imaging in bones, however they can also be T2 and (often but not always) used in scanning the brain.

Question 12

The skeletal system is split into two subgroups named the?

Answer 12

Axial and appendicular

Question 13

What is the axial skeletal system comprised of?

Answer 13

The axial skeleton consists of the bones of the skull (cranium), vertebral column, ribs, and sternum

Question 14

What is the appendicular skeletal system comprised of?

Answer 14

the appendicular skeleton system is made of the bones of the limbs

Question 15

Is cartilage sometimes included in the skeletal system?

Answer 15

Yes.

Question 16

Define avascular

Answer 16

A lack of blood vessels

Question 17

Define the three types of cartilage

Answer 17

Hyaline, elastic, fibrocartilage

Question 18

What are the two types of bone?

Answer 18

Compact and spongey

Question 19

Define avascular necrosis

Answer 19

Associated with the necrosis (death of) bone cells

Question 20

The site where two skeletal elements come together are termed?

Answer 20

Joints

Question 21

Define a synovial joint

Answer 21

Usually, it is a joint with a cavity in a sense. And this cavity is often filled with hyaline cartilage.

Question 22

Define a solid joint

Answer 22

There is no cavity, and the bones are held together by connective tissue/cartilage. Movement is far more restricted that a synovial joint.

Question 23

List the types of synovial joints

Answer 23

• Plane (sliding)
• Hinge (elbow)
• Pivot (allow rotation)
• Bycondylar (Knee joints)
• Condylar (wrist)
• Saddle (Thumb)
• Ball and socket (hip joint)

Question 24

List the two main branches of solid joints

Answer 24

Fibrous joints
- Fixed joints between bones held together by dense, fibrous tissue
