50) Kinds of muscles and its properties.
There are three types of muscle found in the human body:
Skeletal muscle
Skeletal Muscles are those which attach to bones and have the main function of contracting to facilitate movement of our skeletons. They are also sometimes known as striated muscles due to their appearance. The cause of this 'stripy' appearance is the bands of Actin and Myosin which form the Sarcomere, found within the Myofibrils.
Skeletal muscles are also sometimes called voluntary muscles, because we have direct control over them through nervous impulses from our brains sending messages to the muscle. Contractions can vary to produce powerful, fast movements or small precision actions. Skeletal muscles also have the ability to stretch or contract and still return to their original shape.
Skeletal muscle fibre type
Not all fibres within Skeletal muscles are the same. Different fibre types contract at different speeds, are suited to different types of activity and vary in colour depending on their Myoglobin (an oxygen carrying protein) content.
Smooth muscle
Smooth muscle is also sometimes known as Involuntary muscle due to our inability to control its movements, or Unstriated as it does not have the stripy appearance of Skeletal muscle. Smooth muscle is found in the walls of hollow organs such as the Stomach, Oesophagus, Bronchi and in the walls of blood vessels. This muscle type is stimulated by involuntary neurogenic impulses and has slow, rhythmical contractions used in controlling internal organs, for example, moving food along the Oesophagus or contricting blood vessels during Vasoconstriction.
Cardiac muscle (heart muscle)
This type of muscle is found solely in the walls of the heart. It has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control. However this type of muscle is highly specialised. It is under the control of the autonomic nervous system, however, even without a nervous imput contractions can occur due to cells called pacemaker cells. Cardiac muscle is highly resistant to fatigue due to the presence of a large number of mitochondria, myoglobin and a good blood supply allowing continuous aerobic metabolism.
51) Contractive apparatus of the muscles.
Organelles (a nucleus, nucleolus, mitochondrion, Golgi apparatus, etc.), there are contractive apparatus of the cells, consisting of 1000 - 2000 in parallel located myofibrillas with diameter 1-2 microns, and also cellular organelles: sarcoplasmic reticulum and system of cross-section tubules.
Myofibrilla has 2 zones: A -zone - dark line which in polarized light give double refraction, i.e. possess property of anisotropy (from here the name: A-zone), I-zone - the light lines, not giving double refraction, that is isotropic (from here the name: I-zone). In the field of an I-zone there is a dark narrow line - Z-disk. The interval between two Z-disks is called sarcomere, it is elementary contractive unit of a muscular cell. Sarcomere is the ordered system of the thick and thin strands. Thick strand consists of fiber of myosin. The thin strand consists of fiber actin.
