Can someone please write a 250-word essay about one of these systems

Answer 1

Muscular and skeletal systems:

Muscular systems:

Muscular systems are systems that involves three major muscles in its system which are described below,

• Skeletal muscle
• Cardiac muscle
• Smooth muscle

The functions of these three muscles are together makes the muscular system.

Skeletal muscle:

• The skeletal muscles are like other striated muscles which are majorly composed of muscle fibers containing the myofibrils, which are majorly composed of sarcomeres.
• They are majorly involved in supporting the bones and the movement of human body.
• There are around 639 skeletal muscles in the entire body of a human being.

Cardiac muscle:

• Cardiac muscle are involuntary muscles that are found near the heart. They are controlled by the sinus node.

Smooth muscle:

• Smooth muscle are muscle that are found around the walls of organs such as intestines and stomach. They function automatically without any awareness.
• Thus these three are the major muscles that put up together muscular system and there play a major role in various body functions such as Mobility, posture, stability and other related functions.

Skeletal system:

• Skeletal muscles are voluntary muscles that support the skeleton and helps in moving the bones.  These skeletal muscles gets contracted due to some reactions which inturn causes movement in the body and hence it is helpful in the functioning of body movement.Their other functions involve nutrition and temperature regulation.

Both muscular and skeletal systems play a major role in the functioning of the human body and act as the prominent system that is necessary for a healthy human body.
