muscle muscle. the contractile tissue that effects the movement of and within the body. Muscle tissue in the higher animals is classified as striated, smooth, or cardiac, according to its structure and function. Striated, or skeletal, muscle forms the bulk of the body's muscle tissue and gives the body its general shape.It is called striated because it appears striped, in alternating bands of light and dark, when viewed under a microscope, and animals have conscious control over most of their striate muscles.ll types of muscles consist of muscle fibers. Striated muscle fibers in skeletal muscles form bundles joined together by layers of connective tissue. The ends of muscle fibers are intertwined with tendon fibers, and through this combination muscular tension is transmitted to the skeletal bones.

MUSCLE skeletal muscle, striated muscle - a muscle that is connected at either or both ends to a bone and so move parts of the skeleton; a muscle that is characterized by transverse stripes pronator - a muscle that produces or assists in pronation

Why are muscles important? Muscles are a type of tissue composed of contractile cells or fibers that effect MOVEMENT of a part of the human body. Its outstanding characteristics are the ability to shorten or contract and possess the properties of irritability, conductivity, and elasticity.he primary function of muscle cells is to allow movement of the  different parts of the body. One important internal organ that is  controlled by muscle cells is the pumpin … g of the heart. 3 people found this useful. Mrsorientelorenzo.

Muscle structure and function The basic function of muscle is to generate force. Secondarily, muscles can provide some shape and form to the organism. Anatomically and functionally, muscle can be divided into two types, smooth and striated. Striated or striped muscle can be further divided into skeletal muscle and cardiac (heart) muscle.econdarily, muscles can provide some shape and form to the organism.

- Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.n the anterior and posterior views of the muscular system above, superficial muscles (those at the surface) are shown on the right side of the body while deep muscles (those underneath the superficial muscles) are shown on the left half of the body.

- Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium.It is formed during embryonic development through a process known as myogenesis. Muscle tissue varies with function and location in the body.In mammals the three types are: skeletal or striated muscle; smooth or non-striated muscle; and cardiac muscle, which is sometimes known as semi-striated. Smooth muscle, neither striated in structure nor under voluntary control, is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector pili in the skin (in which it controls erection of body hair).

- Myofilaments are the filaments of myofibrils, constructed from proteins, principally myosin or actin. Types of muscle are striated muscle (such as skeletal muscle and cardiac muscle), obliquely striated muscle (found in some invertebrates), and smooth muscle. Various arrangements of myofilaments create different muscles.

- Skeletal muscle: Skeletal muscle, in vertebrates, the type of muscle that is attached to bones by tendons and that produces all the movements of body parts in relation to each other.

The Sliding Filament Theory of Muscle Contraction Muscle is a specialized contractile tissue that is a distinguishing of animals. Changes in muscle length support an exquisite array of animal movements, from the dexterity of octopus tentacles and peristaltic waves of Aplysia feet to the precise coordination of linebackers and ballerinas.

Types of Muscles and Their Functions Muscles are the contractile tissues [Tissue that is able to contract] that are responsible for performing various voluntary and involuntary functions. Muscles can be regarded as motors of the body. Muscles are so named because, many of them resemble a mouse, with their tendons representing the tail.

- The muscular system is an intricate and complex network of muscles that are vital to the human body. Muscles play a part in everything you do, from chewing to dancing to sleeping. They control our heartbeat and breathing, help our digestion, and allow us to move in the world.

Tissue (biology) In biology, tissue is a cellular organizational level intermediate between cells and a complete organ. A tissue is an ensemble of similar cells from the same origin that together carry out a specific function.Organs are then formed by the functional grouping together of multiple tissues.his matrix can be liquid or rigid. For example, blood has plasma as its matrix and bone's matrix is rigid.Connective tissue gives shape to organs and holds them in place. Blood, bone, tendon, ligament, adipose and areolar tissues are examples of connective tissues.

Nerves move muscles in response to voluntary and autonomic (involuntary) signals from the brain.

- Lesson Summary. In summary, skeletal muscles are organs that are directly or indirectly attached to bone. Skeletal muscles serve a variety of functions including support and movement and homeostasis. Skeletal muscle contraction can result in muscle shortening and thus movement of the bone to which it is attached. Additionally, skeletal muscle contraction can maintain posture and position.
