What other structures can be found in a muscle?

Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Skeletal muscles vary considerably in size, shape, and arrangement of fibers.

What structures can be found in a muscle?

Skeletal muscles contain connective tissue, blood vessels, and nerves. There are three layers of connective tissue: epimysium, perimysium, and endomysium. Skeletal muscle fibers are organized into groups called fascicles. Blood vessels and nerves enter the connective tissue and branch in the cell.

What special structures are found in the human muscle cells?

Skeletal muscle cells form elongated fibers in the body. They have multiple nuclei within each cell. This contrasts with the majority of other cells in human bodies. They also contain many mitochondria, cellular organelles that produce adenosine triphosphate (ATP), the body’s fuel.

What are three muscle structures?

In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood.

What are the 4 structures of the muscular system?

Structure of the Muscular System

  • Skeletal Muscles. …
  • Smooth Muscles. …
  • Tough Tendons. …
  • Flexible Ligaments. …
  • Adipose Tissue.

How is a muscle cell Specialised?

Many cells are specialised. They have structures that are adapted for their function. For example, muscle cells bring parts of the body closer together. They contain protein fibres that can contract when energy is available, making the cells shorter.

What are muscle tissues?

Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

What is the major structure of the muscular system?

The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

Which two structures make up the muscular system muscles and bones?

Introduction. The musculoskeletal system is made up of bones, cartilage, ligaments, tendons and muscles, which form a framework for the body. Tendons, ligaments and fibrous tissue bind the structures together to create stability, with ligaments connecting bone to bone, and tendons connecting muscle to bone.

How are structures in the muscular system organized?

Smooth muscle cells form layers that are usually arranged so that one runs parallel to an organ and the other wraps around it. These two muscle layers then contract in turn, causing alternating dilation and contraction or lengthening and shortening of the organ, moving substances through internal passages.

What is the basic structure of muscle tissue?

The muscular tissues are bundled together and surrounded by a tough connective tissue similar to cartilage known as epimysium. The bundle of nerve cells that run in long fibers called fascicles are surrounded by the epimysium. The fascicles are surrounded by a protective layer known as perimysium.

What is the meaning structure and types of muscles?

Structure of Muscle

A muscle consists of many muscle tissues bundled together and surrounded by epimysium, a tough connective tissue similar to cartilage. The epimysium surrounds bundles of nerve cells that run in long fibers, called fascicles.

What is the structure and function of muscle tissue?

Muscle tissue consists of fibers of muscle cells connected together in sheets and fibers. Together these sheets and fibers and known as muscles, and control the movements of an organisms as well as many other contractile functions.

Where are muscle tissues found in the body?

Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton.

What are examples of muscle tissue?

skeletal muscle (or the striated voluntary muscle) tissue. smooth muscle (or the non-striated involuntary muscle) tissue. cardiac muscle (or the heart muscle) tissue.

How is skeletal muscle structure?

An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium. Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.

What is the structure of smooth muscle?

Smooth muscle consists of thick and thin filaments that are not arranged into sarcomeres giving it a non-striated pattern. On microscopic examination, it will appear homogenous. Smooth muscle cytoplasm contains a large amount of actin and myosin. Actin and myosin act as the main proteins involved in muscle contraction.

What structure within muscle tissue is surround by membrane and has multiple nuclei?

Each muscle bundle contains a number of muscle fibers [4,5]. Each muscle fiber is covered by plasma membrane called sarcolemma enclosing the sarcoplasm. Muscle fiber is syncitium due to presence of many nuclei in sarcoplasm. The sarcoplasmic reticulum of the muscle fibers stores calcium ions.
