Question

Give two main differences between unstriped and striped muscular tissues and give examples of each.

Answer 1

A soft tissue found in both animals and humans that expand and contract are known as muscles. They contain protein filaments of actin and myosin that produce the movement of contraction and expansion. They help in the movement of the body.

Complete answer:

STRIPED MUSCLE	UNSTRIPED MUSCLE
1. Striped muscles are also known as striated muscles that are found in between bones and tendons.	1. Unstriped muscles are also known as unstriated muscles that are smooth muscles that are used by the organs to apply pressure in the blood vessels.
2. Striated muscles are long, cylindrical and have blunt ends.	2. Unstriated muscles are short, spindle-shaped and have pointed ends.
3. Striated muscles are mainly found in limbs, tongue, pharynx, etc.	3. Unstriated muscles are found in organs such as blood vessels, intestines, stomach, etc.
4. Striped muscle cells are multinucleated with the nucleus present at the periphery of the cell.	4. Unstriped nuclei are uninucleated with the nucleus present at the centre of the muscle cell.
5. The actions performed are voluntary action.	5. The actions performed are involuntary action.
6. Dark and light bands are present on the muscle cell.	6. No bands are present on the muscle cell.

Note:
Another type of muscle known as cardiac muscles is also present in the body. These are specialized muscle cells present only in the heart. They are mainly responsible for pumping blood throughout the body. The cardiac muscle cells are short, branched and cylindrical cells having flat ends. They perform involuntary action.
