Major structures of the muscular system

Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. Without muscle humans could not live.

The main function of the muscular system is designed to aid movement within the human body.

Major structures of the muscular system. The muscular system is made up of muscle tissue and is responsible for functions such as maintenance of posture locomotion and control of various circulatory systems. This includes the beating of the heart and the movement of food through the digestive system. The muscular system is closely associated with the skeletal system in facilitating movement.

The structure of the muscular system is complex but generally muscles are divided into three categories. Skeletal smooth and cardiac. Some muscles are voluntary while others are involuntary.

Additionally certain muscles are striated while others are not. Only the walls of the heart have cardiac muscle tissue. The body has 3 main types of muscle tissue.

1Skeletal 2 Smooth and 3 Cardiac. ÎMyotendinal junction - area where tendon fibers insert into muscle connective tissue and also into bone matrix Sharpeys fibers. ÎNeuromuscular junction - motor endplate where nerve fibers connect with myofibrils.

In leg muscle one neuron innervates several hundred to 1000 muscle fibers. Besides muscles the muscular system contains the tendons which attach the muscles to the bones. Skeletal system whose main component is the bone.

Bones articulate with each other and form the joints providing our bodies with a hard-core yet mobile skeleton. Fascia is a connective tissue that surrounds muscles and binds muscles to other structures. Major skeletal muscles of the lower body include the hamstrings and gluteus maximus in the back and the.

The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a persons body weight.

Each of these muscles is a discrete organ constructed of skeletal muscle tissue blood vessels tendons and nerves. The muscular system is composed of three types of muscle Skeletal Cardiac and Smooth. These muscle function to move the skeleton or move materials.

There are three types of muscle fibers cardiac skeletal and smooth. Skeletal muscle is voluntary multi-nucleated and striated. Cardiac muscle is involuntary multi-nucleated and striated.

What are the two main structures of the muscular system. Visceral muscle is found inside of organs like the stomach intestines and blood vessels. Found only in the heart cardiac muscle is responsible for pumping blood throughout the body.

The main function of the muscular system is designed to aid movement within the human body. Any type of movement that we attempt involves the use of at least one muscle. The gross structure is basically attached to all bones within the body that is why it is more commonly known as the musculo-skeletal system.

Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers. It controls the movement of an organism.

The cytoplasm in the muscle fibers is called sarcoplasm. It contains a network of membrane called the sarcoplasmic. Human muscle system the muscles of the human body that work the skeletal system that are under voluntary control and that are concerned with movement posture and balance.

Broadly considered human musclelike the muscles of all vertebratesis often divided into striated muscle smooth muscle and cardiac muscle. Without muscle humans could not live. The primary job of muscle is to move the bones of the skeleton but muscles also enable the heart to beat and constitute the walls of other important hollow.

The muscular system is an organ system consisting of skeletal smooth and cardiac muscles. It permits movement of the body maintains posture and circulates blood throughout the body. The muscular systems in vertebrates are controlled through the nervous system although some muscles such as the cardiac muscle can be completely autonomousTogether with the skeletal system in the human it.
