Question 18

compact bone tissue

Answer 18

wall of the diaphysis

Question 19

spongy bone tissue

Answer 19

cancellous epiphysis, Red marrow

Question 20

synovial joint

Answer 20

the articulating surfaces of the bones are not directly connected, But instead come into contact with each other within a joint cavity that is filled with a lubricant fluid

Question 21

pivot joint

Answer 21

Uniaxial joint; allows rotational movement

-Atlantoaxial joint(c1-c2 vertebrae articulation proximal rediolunar joint

Question 22

hinge joint

Answer 22

uniaxial joint, Allows flexion/ extension movement

-knee, elbow, ankle interphalangeal joint of fingers and toes

Question 23

saddle joint

Answer 23

Biaxial joint; allows flextion/extension, abduction/adduction and circumduction movements
-First carpometacarpal joint of the thumb, Sternociavicular joint

Question 24

plane joint

Answer 24

the multiaxial joint allows inversion and eversion of foot or flexion, extension, and lateral flexion of the vertebral column
-intertarsal joints of foot superior-inferior articular process articulations between vertebrae

Question 25

Condyloid joint

Answer 25

Biaxial Joint Allows flexion/extension, abduction/adduction, and circumduction movement
-metacarpophalangeal(knuckle) joints fo fingers; radiocarpal joint of wrist metatarsophalangeal joints for toes

Question 26

balls and socket joints

Answer 26

The multiaxial joint allows flexion/extension, abduction/adduction, circumduction, and medial/lateral rotation movements
-shoulder and hip joints

Question 27

flexion/ Extension

Answer 27

movement that takes place withing the sagital plane and involve anterior or posterior movements of the body or limbs

Question 28

adduction/anduction/circumdiction

Answer 28

adduction-moves limbs laterally away from the midline of the body(condyloid saddle, and ball- and-socket joints
abduction-brings the limbs toward the body or across the midline(condyliod, saddle, and ball-and-socket joints)
Circumduction(biaxial condyloid, saddle, Ball- and-socket)

Question 29

rotation

Answer 29

can occur within the vertebral column at a pivot joint, or at a ball-and-socket joint
Medial(internal)rotation-towards the midline
Lateral (external)rotation-away from the midline

Question 30

supination/pronation

Answer 30

pronation-is the motion that moves the forearm from the supinated position to the pronated position
supination-the opposite motion

Question 31

Dorsiflextion/Plantar flexion

Answer 31

movements at the ankle joint

Question 32

inversion/Eversion

Answer 32

the turning of the foot to the angle to the bottom of the foot towards the midline

Question 33

protraction/ Retraction

Answer 33

protraction of the scapula occurs when the shoulder is moved forward
retraction is the opposite motion with the scapula being pulled posteriorly and medialy

Question 34

opposition/reposition

Answer 34

opposition the thumb movement that brings the tip of the finger
reposition- returning the thumb to anatomical position
