Muscle tissue
The main characteristic of muscle tissue is its ability to contract, or shorten, making movement possible. Muscle contraction results from contractile proteins located within the muscle cells. Muscle cells are sometimes called muscle fibers because they often resemble tiny threads
Classification of muscles
- Skeletal muscle tissue
- Cardiac muscle tissue
- Smooth muscle tissue
| SKELETAL MUSCLE TISSUE | |
| Structure | Voluntary, cylindrical, multinucleated & striated |
| Location | Attached to bones |
| Function | Motion, posture, heat production, protection |
| CARDIAC MUSCLE TISSUE | |
| Structure | Involuntary, uni-nucleated and striated |
| Location | Heart wall. |
| Function | Pumps blood to all parts of body. |
| SMOOTH MUSCLE TISSUE | |
| Description | Involuntary and non-striated |
| Location | located in the wall of hallow internal structure like Blood vessels, stomach, intestine, and urinary bladder |
| Function | Motion of blood vessels and airways etc. |
