Слайды и текст этой презентации
Слайд 2The significance of muscles :
-
сause all kinds of movements;
the body in vertical position;- participate in formation of body cavities
Слайд 3
The significance of the knowledge
of muscles:
-
the muscular system is an indicator of the state of
health;- doctor can influence on organism through the muscular system;
- muscles are in soft tissue composition of all the regions of body.
Слайд 4Newborns – 20-22 percent of body weight
Adults – 40 percent
of body weight
Seniles – 25-30 percent of body weight
Слайд 6Each muscle consists of:
- sceletal muscle tissue
- connective tissue- blood and lympatic vessels
- nerves
Слайд 7Striated muscle fibers:
- length –4-12сm
- thick –0,1mm
- sarcoplemma
- sarcoplasm
- nuclei
- myofibrils
- myoglobin
Слайд 8There are two kinds of sceletal fibers:
white
fibers- contain a lot of myofibrils;
a little myoglobin;contract fast,
tire quickly.
red fibers- contain a lot myoglobin.
a little myofibrils,
contract slowly,
don`t tire quickly
Слайд 9Loose connective tissue forms:
- endomysium
(around each muscle
fiber )
- inner perymysium (around several fibers )
- outer perymysium (around whole muscle )
Слайд 10Functions of loose connective tissue:
- supports muscle fibers;
- demarcates muscle
fibers;- holds vessels, nerves
Слайд 11Tendons- dense connective tissue
- initial
- end
- intermediate
- intramuscular
- tendons intersection
- aponeurosis
Слайд 14Myon is a piece of striated muscle fiber with one
motor nerve ending.
The myon is the structural unit of the
muscles
