B. 640-850
C. 1150-1500
D. More than 2000

Answer 1

Hint: Muscles are a group of muscle tissues that contract to create strength. Muscles are important for the body to ensure stability and mobility. They are present in almost all parts of the body, and the type of muscle present in a particular body part is functionally very suitable for that area.

Complete answer:
Let’s before answering study about some important points about muscles and type of muscles.
Skeletal muscles: These muscles are located in the limbs, body wall, tongue, throat and at the beginning of the oesophagus and are under the control of the will of the animal. These muscle fibers are found in bundles and usually attached to the skeleton. Each muscle fiber is an elongated cell surrounded on the outside by a sensitive membrane called the sarcolemma.
Smooth muscle tissue (non-striated muscle): These muscles are located in the back of the oesophagus, stomach, intestines, lungs, urogenital tract, bladder, blood vessels, iris, skin dermis and muscle file retainers. Hair. Smooth muscle never connects to the skeleton. These fibers or muscle cells are elongated and spindle-shaped. Each fiber contains an oval nucleus surrounded by cytoplasm (sarcoplasm). In the cytoplasm, myofibrils are located elongated. There is no sarcolemma, but the fibers are covered by a plasma membrane.
Cardiac muscles: The heart muscle is located on the wall of the heart and in the walls of the large veins (for example, pulmonary vein and superior vena cava) through which these veins enter the heart. These fibers reveal the nature of the striped and striped muscle fibers. Each fiber is a long, cylindrical structure with a specific sarcolemma. The fibers are mononuclear and the nucleus is close to the center.
It is estimated that there are more than 650 skeletal muscles in your body. Other muscle tissue, such as smooth muscle, is usually at the cellular level, meaning you can actually have billions of smooth muscle cells. Nearly every muscle represents part of an identical bilateral pair of muscles on either side, resulting in about 320 pairs of muscles. However, the exact number is difficult to determine because different sources group the muscles differently, i.e. in terms of what is defined as distinct muscle parts or as many muscles. The muscles of the human body can be divided into several groups, including muscles related to the head and neck, trunk or torso muscles, upper leg muscles, and lower leg muscles.

Hence, from above points it’s clear that the correct option is 640-850 “B”.

Note:
Muscle tissue generally develops from the embryonic mesoderm, but the iris muscle and myoepithelial cells from the salivary, milk, and sweat glands come from the embryonic ectoderm. Special properties of muscle tissue shrink, that is. Muscle tissue cells can contract significantly and return to their original relaxed state. Muscle cells contract in a certain direction. Another property of muscles is electrical stimulation. This is due to the energy stored in the difference in electric potential on the plasma membrane.
