Flashcards in skeletal system Deck (46):
1
5 function of bones?
-form framework to support movement
-protects vital organs
-attach to muscles to provide movement
-help produce red & white blood cells
-store calcium supply in body
2
8 bones that form cranium
(1) frontal , (2) parietal , (2) temporal , (1) ethmoid, (1) occipital, (1) sphenoid
3
frontal bone (cranium)
forms forehead, orbital roof, anterior cranial floor
4
parietal bone (cranium)
roof / upper side of cranium
5
temporal bone (cranium)
forms side and base of cranium
6
ethmoid bone (cranium)
part of orbit floor of cranium
7
occipital bone (cranium)
forms the back/ base of cranium
8
sphenoid bone (cranium)
forms anterior base of skull and part of wall of orbit
9
26 vertebrae?
protect spinal cord and support head/trunk of body
10
what are the 26 vertebrates?
7 cervical (neck) , 12 thoracic (chest) , 5 lumbar (lower back), 1 sacrum (back/ pelvic girdle) , 1 coccyx (tail bone)
11
true ribs?
first 7 ribs, attached to sternum (breastbone)
12
false ribs?
next 3 ribs, attached to the cartilage of rib
13
floating ribs?
last 2 ribs, no attachment to the front of the body
14
small piece of cartilage attached to the sternum?
xiphoid process
15
three regions on each os coxae?
Illium, ischium, and pubis.
16
3 types of joints
diarthrosis, amphiarthrosis, synarthrosis
17
diarthrosis degree of movement? example?
-freely movable
- ball socket on shoulder
18
amphiarthrosis degree of movement? example?
-slightly movable
-attachment of rib to thoraci
19
synarthrosis degree of movement? example?
-immovable
-cranium
20
purpose of ligaments?
tissue that connects bone to bone.
21
arthritis?
inflammation of joints
22
fracture?
crack or break in bone
23
osteomyelitis?
bone inflammation
24
osteoporosis?
bones become brittle/ fragile from loss of tissue
25
sprain?
twisting actions tears ligaments of joints
26
bursitis?
inflammation of a bursae
27
dislocation?
bone forcibly displaces from joint
28
scoliosis?
abnormal lateral curvature of the spine
29
what body parts are the long bones?
bones in legs and arms
30
what do the long bones do? why important?
-provide support and strength
- important because red and yellow marrow
31
wheres red marrow found? what dose it do?
-found in proximal end of humerus (arm) and femur (leg) as well as vertebrae, ribs, cranium and sternum.
-makes RBC's, platelets and some WBC's
32
whats blood made up of?
48% RBC's, 2% WBC's, 50% plasma
33
yellow marrow?
fat cells
34
whats the skull used for? made up of?
-provides protection for are brain
- its made up of cranial bones and facial bones
35
how many bones make up the skull?
eight bones
36
sutures
area where cranial bones join together
37
whats the vertebral spinal column?
26 bones that make up the vertebral column, they protect the spinal cord and support the head and trunk of body
38
what are pads between vertebrates do?
act as disks as shock absorbers, allows you to twist and bend
39
joints?
area where two bones attach for purpose of motion in the body
40
greenstick fracture?
when the bone is bent, mostly in kids
41
comminuted fracture?
when bones shattered into a bunch of pieces
42
impacted fracture?
the ends of bone are driven into each other
43
pathologic fracture?
caused by disease that weekends the bones
44
grout?
type of arthritis that forms when too much uric acid builds up in the body, joints inflame and swell up alot
45
bursitis?
inflammation of a small fluid sac that's surrounding the joint.
