Musculoskeletal System

The musculoskeletal system includes bones, muscles, joints and related structures such as the tendons and connective tissue that function in the support of movement of body parts.

2

Articulation

place of union between two or more bones, also called a joint

3

Hematopoiesis

Production of blood cells, performed by the bone marrow
poeisis: development,
hemat/o: blood.

4

Tendons

connective tissue that binds muscle to bone
-as muscle contracts by the tendon, the bone joint provides movement

5

Muscles: Three Types

1. Skeletal
2. Smooth Muscle
3. Cardiac Muscle

6

Skeletal Muscle

attached to bones and provides movement; voluntary

7

Smooth Muscle

assist in internal processes like digestion, circulation, and urination; involuntary
ex: GI tract, GU tract

8

Cardiac Muscle

only in the heart wall, as it forms the myocardium

9

Bones

provide a framework to support and protect the body
-point of attachment with muscles
-held close together at the point by ligaments which are flexible bands of fibrous tissue
-produce blood cells within bone marrow (hematopoiesis)

10

Four Types Of Bones

-short
-irregular
-flat
-long

11

Diaphysis

long, main portion of the bone; "shaft"

12

Distal and Proximal Epiphysis

the two ends of the bone

13

Ligaments

connect bone to bone

14

Tendons

connect muscle to bone

15

crani/o

cranium

16

femor/o

femur

17

patell/o

patella

18

tibi/o

tibia

19

pelv/o, pelv/i

20

21

22

vertebr/o

vertebra

23

stern/o

sternum

24

cost/o

ribs

25

radi/o

radius

26

fibul/o

fibula

27

tars/o

tarsals

28

phalang/o

phalanges

29

Bunion (Hallux Valgus)

deformity characterized by lateral deviation of the great toe
-caused by ill-fitting shoes

30

Bunion: Signs + Symptoms

-tissues surrounding joint become red, swollen, and tender
-corn or callus may develop where the first and second toe overlap
-limited movement of big toe
