Skeletal system

Question 1

Components of skeletal system

Answer 1

Bones, cartilage, connective tissue to stablize of connect bones, ligaments and joints

Question 2

Primary function of the skeletal system

Answer 2

• Structural support for the entire body
• storage of minerals and lipids
• blood cell production by red bone marrow
• protection of soft tissues and organs
• leverage for body movements

Question 3

General shape of bones

Answer 3

Long bones
short bones
flat bones
irregular bones

Question 4

What is a long bone and give an example

Answer 4

longer than they are wide
bones of limbs (femur in legs, humerus in arms)

Question 5

what is a short bone and give an example

Answer 5

width and length are roughly equal
bones of wrist (carple bones)

Question 6

what is a flat bone and give an example

Answer 6

thin and relatively broad
shoulder blades (breast bone, ribs, skull bones, hip bone)

Question 7

irregular bones

Answer 7

complex shape
vertebrae, facial bones (maxillary, zygomatic etc

Question 13

Function of vertebral column

Answer 13

Provides support,
-by bearing weight of head, neck and trunk and transfers weight to appendicular skeleton and lower limbs

Question 17

Function of thoracic cage

Answer 17

-support the thoracic cavity
-protects heart, lung and other internal organs
-attachment base for muscles involved in respiration

Question 18

upper limbs
pelvic girdles
lower limbs

Question 19

Answer 19

joing strength decreases

Question 20

Where are joints found

Answer 20

exist wherever two boens meet

Question 21

Type of joint movements

Answer 21

gliding
angular movemnt
rotation
speical movements

Question 22

What is gliding (joint movement) and give an example

Answer 22

when two (flat) surfaces (of bones) slide past each other
(carples, tarsals)
very slight movement

Question 23

Three types of posteior- anterior angular movement

Answer 23

Flexion
-reduces angle between elements
Extension
-increases amgle between elements
Hyperextension
-extension past anatomical position

Question 24

two type of frontal plane angular movement

Answer 24

abduction
-moves away from longitidunal axis (abducting means taking away)
adduction

Answer 25

circumduction

Question 26

What is rotation (joint movement) and what are the two types

Answer 26

turning around longitudnal axis of the body

Pronation (hand turn to face down, anticlockwise, internal rotation)

Supination (hand turn to face up, clockwise, externa rotation)

Question 27

Special movements and their names

Answer 27

Opposition: thumb movment toward finger or palm, grasping
protraction: move anteriorly in horizontal plane, pushing forward
retraction: pulling back
elevation: move in superior direction, up
depression: down
