Flashcards in Chapter 30 - Musculoskeletal Trauma and Nontraumatic Frectures Deck (27):
1

the functions of the muscularskeletal system are:
1
2
3
4
5

give the body shape
protect internal organs
provide for movement
store salts and other materials for metabolism
produce red blood cells

2

three kinds of muscle:

cardiac
voluntary (skeletal)
involuntary (smooth)

3

connect the muscle to the bone

tendons

4

connect bone to bone

ligaments

5

a strong, smooth, flexible, compressible, and slippery substance found at the point of articulation of two bones. allows the bones to ride over each other during movement with relatively little friction.

cartilage

6

bending motion that moves the extremity toward the body

flexion

7

bending motion that moves the extremity away from the body

extension

8

movement of a body part toward the midline of the body

adduction

9

movement of a body part away from the midline of the body

abduction

10

turning along the axis of the bone or joint

rotation

11

movement through an arc of a circle or in a circular motion from a central point

circumduction

12

skeletal systems 6 basic components

skull
thorax
pelvis
upper extremities
lower extremities
spine

13

the axial skeletal system is composed of:

head
thorax
spine

14

the appendicular skeletal system is made up of:

bones in extremities
including:
shoulder girdle and pelvis

15

bones of upper extremity:
which consists of:
shoulder girdle
arm
forearm
hand

clavicle
scapula
humerus
radius
ulna
carpal
metacarpals
phalanges

16

bones of the lower extremity:
which consists of:
pelvis
thigh
leg
foot

pelvis (including ilium, ischium, and pubis)
femur
patella
tibia
fibula
calcaneus
tarsals
metatarsals
phalanges

17

a break in the continuity of a bone

fracture

18

s/s
pain
tenderness
deformity
discoloration
tingling or abnormal sensation; may be nerve injury
loss of feeling; may be nereve injury
weakness; may be nereve injury
loss of muscle control; may be nereve injury
inability to move the extremity
decreased pulse amplitude, increased cap refill

fracture

19

degenerative bone disorder associated with an accelerated loss of minerals, primarily calcium, from the bone.

osteoporosis

20

an injury to a muscle or a muscle and tendon, possibly caused by overextension, or overstretching.

strain

21

an injury to a joint capsule, with damage to or tearing of the connective tissue, and usually involves ligaments.

sprain

22

the displacement of a bone from its normal position in a joint.

dislocation

23

a force that causes injury some distance away from the point of impact

indirect force

24

direct blow.

direct force

25

a force that twists a bone while one end is held stationary

twisting force

26

when assessing an extremity for the possibility of a fracture or dislocation, remember to evaluate the six P's:

pain
pallor
paralysis
paresthesia (numbness)
pressure
pulses

27

a condition in which increased tissue pressure in a confined space causes decreased blood flow, leading to hypoxia and possible muscle, nerve, and vessel impairment, which may be permanent if the cells die

compartment syndrome
