Question 1

frontal plane

Answer 1

Divides the body in to anterior and posterior sections.
Most common motions
Abduction
Adduction

Question 2

sagittal plane

Answer 2

Divides the body into left and right sections
Most common movements:
Flexion
Extension

Question 3

transverse plane

Answer 3

Divides the body into upper and lower sections.
Most common movements:
Internal Rotation
External Rotation

Question 4

Linear Movements - Rectilinear

Answer 4

Linear Movements - Rectilinear
Occurs in straight line 
   from one location to 
   another
All parts move in the SAME direction at the SAME time.

Question 5

Linear Motion – Curvilinear

Answer 5

Linear Motion – Curvilinear
Occurs in curved line 
   from one location to 
   another
All parts move in the SAME direction at the SAME time.

Question 6

angular motion

Answer 6

Angular
All parts move at the same angle, in the same direction, at the same time.
They DO NOT travel the same distance

Question 7

rotational motion

Answer 7

Rotational Motion

Movement occurring around a vertical or longitudinal axis

Question 8

Osteokinematics

Answer 8

Describes movement of bones around a joint axis.
This refers to the names we use to describe joint motion.
Examples: flexion, extension etc.
Refer to slides 11-18

Question 9

Arthrokinematics

Answer 9

Movement within a joint (intra articular motion).

Question 10

types of joints

Answer 10

Fibrous joints
Cartilaginous joints
Synovial Joint

Question 11

fibrous joints

Answer 11

Suture Joints (Synarthrosis)
     Only occurs in the skull

Ligamentous Joint
Ligaments hold the joint together
Small amounts of movement occur
Distal Radio Ulnar Joint (for example)

Gomphosis
Interlocking
Teeth

Question 12

Cartilaginous joints

Answer 12

Cartilaginous joints absorb shock and allow some motion
Provide stability
Examples:
Vertebrae have disks
Sternoclavicular joint

Question 13

Synovial Joint

Answer 13

No direct contact between bone ends
Has a “joint capsule”
Capsule filled with synovial fluid
Mobile

Question 14

Classification of Synovial Joints

Answer 14

Number of axes
Kind of joint motion
Degrees of freedom
Number of planes in which a joint can move

Question 15

Nonaxial joint

Answer 15

Nonaxial joint
Has small amounts of linear motion
No angular motion
Gliding usually occurs
Examples:
Costovertebral Joints
Intervertebral Joints
Degrees of Freedom
???

Question 18

types of Cartilage

Answer 18

Cartilage
Articular cartilage (Hyaline)
covers ends of bones
Has smooth, slick surface

Fibrocartilage (meniscus, disks, labrum)
Provides shock absorption

Elastic cartilage (found in the ear and larynx)
        Can be stretch and resume shape

Question 19

tendons

Answer 19

Tendons

Attach muscles to the bones

Question 20

Aponeurosis

Answer 20

Aponeurosis

Flat tendinous sheet (latissimus dorsi)

Question 21

bursae

Answer 21

Bursae

Padlike sacs around most joints where friction is greatest
