The muscular system anatomy and physiology. Tanner Marshall MS Evan Debevec-McKenney Brittany Norton MFA. The muscular system is made up of three types of muscle tissue. Skeletal smooth and cardiac muscle tissue.

They differ in terms of their location cell structure and innervation. But they also share some characteristics. Theyre all excitable meaning that the cells react to a.

Anatomy and Physiology of the Female Reproductive System. As a body system the muscular system serves different important functions for mans survival. Through the skeletal muscles this system maintains the posture of an individual as well as initiate continue and stop body movement.

With the smooth muscles digestion of food is made possible even without conscious thought. Muscles that move the radius and ulna forearmsuperior view of transverse section of arm. Muscles that move the wrist hand and digits Anterior superficial and deep views.

Overall movement of the body. 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 fibers may converge toward a single point or run parallel with other muscles. Maybe theyre circular like the muscle fibers around your mouth and eyes and attach obliquely.

In short the arrangement of a muscles fiber bundles fascicles determines its range of motion and power. In this article well discuss fiber arrangements. The musculoskeletal system locomotor system is a human body system that provides our body with movement stability shape and support.

It is subdivided into two broad systems. Muscular system which includes all types of muscles in the body. Skeletal muscles in particular are the ones that act on the body joints to produce movements.

Origin and Insertion Most muscles cross at least one joint and are attached at the articulating bones When a muscle contracts it draws one articulating bone toward the other Origin the attachment to the stationary bone Insertion the attachment to the moveable bone. Muscle of the lumbar region that helps extend and laterally flex the vertebral column. Pennate muscle that has a tendon branching within it.

Muscle that lifts the hyoid bone and helps press the tongue to the top of the mouth. Endomysium–fine sheath of connective tissue composed of reticular fibers surrounding each muscle fiber. Perimysium–fibrous connective tissue that surrounds groups of fascicles.

Epimysium–an overcoat of connective tissue that surrounds the whole muscle. The muscular system consists of tiny fibers or cells that contract to help you move your body. Muscles can be attached to bones and to internal organsThey are so important that almost nearly all movement in the body is done by them.

30-40 of our body weight is made up of muscular tissue and we each have approximately 640 muscles in our bodies. The muscular system includes all the skeletal muscles of the head and neck upper and lower extremities and the torso. These muscles are arranged in antagonistic pairs and work to move the limb or body part they control.

Muscle use lever actions in the body to increase efficient the joints are the fulcrums. Tough fibrous band of connective tissue. Extends from the xiphoid process of the sternum to the pubic symphysis.

Thoracolumbar fascia connective tissue Triangular section of fibrous connective tissue found in region of thoracic and lumbar vertebrae. Flexor retinaculum connective tissue located in the palmar surface to the wrist. Encloses entire muscle and epimysium.

Bundle of collagen fibers where muscle meets bone. All 3 connective tissue layers taper and blend. Interwoven with periosteum of bone.

Broad sheet of collagen fibers. Anatomy and Physiology on the musculoskeletal system. The musculoskeletal system is made up of bones cartilage ligaments tendons and muscles which form a framework for the body.

Adhesions cause tissues and organs to stick together. They might connect the loops of the intestines to each other to nearby organs or to the wall of the abdomen. They can pull sections of the intestines out of place.

This may block food from passing through the intestine. Anatomy And Physiology Coloring Workbook Chapter 6 The Muscular System Answer Key. Rules And Regulations Of B Ed.

Did you know you have more than 600 muscles in your body. They do everything from pumping blood throughout your body to helping you move about from one place to another. The muscular and nervous systems enable the involuntary breathing mechanism.

The main muscles in inhalation and exhalation are the diaphragm and the intercostals shown in blue as well as other muscles. Exhalation is a passive action as the lungs recoil and shrink when the muscles relax. Image from Human Anatomy Atlas.
