Name the principal axial muscles of the body and describe their origins insertions actions and inner

There are at least 7 ways to do this. By having descriptive portion included in the muscle name is the major way of aiding one. This can be done by including the Location within the body, origin and insertion points, fascicle organization. The relative positions, structural characteristics and action.

Skeletal The Skeletal System The branches of science that will help you understand the body parts and functions are anatomy and physiology. Anatomy deals with the study of the human body the component parts, structure and position and physiology the study of how the body functions.

Body Systems The body comprises a number of systems including the: Cardiovascular system, Digestive system, Endocrine system, Muscular system, Neurological system, Respiratory system and the Skeletal system.

The Skeletal System The skeletal system comprises of bones and provides four basic functions: Support for tissues and muscle Protection for vital organs Movement through bones and attached muscles Storage for minerals and immature blood cells Growth Ossification is the process by which bone is formed.

This process is known as intramembranous or direct ossification. This process is known as endochondral or indirect ossification - most bones are formed this way.

Support Bones and cartilage that make up the skeleton are the only rigid materials in the body. The bones of the skeleton provide a framework and points of attachment for many of the soft tissues of the body.

The five main classifications of bones are: Skull - protects the brain Vertebrae - protects the spinal cord Thoracic cage - protects the heart and lungs Movement Bones act as levers during movement and provide solid structures to which muscles are attached.

The joints allow movement between bones and these movements are directly related to the type of joint and range of motion. Joints fall into one of three categories: Fixed fibrous or Synarthroses e. Freely Movable joints comprise of four main groups: Ball and Socket e.

The stability of these joints is dictated by the shape of articulating surfaces, their surrounding ligaments and muscles. For example, the knee is given great strength from 2 cruciate and 2 collateral ligaments.

Whilst one of the hardest joints to dislocate is the hip. It is formed with the head of femur fitting neatly into the socket or acetabulum in the pelvis. Articular or hyaline cartilage covers and protects the ends of bones which meet to form a joint and therefore allows freedom of movement.

It is a very hard, smooth material which does not repair itself when damaged. Tendons connect muscle tissue to bone and although more elastic than ligaments have a far greater tensile strength than muscle. Synovial membrane lines the joint cavity and covers the tendons and ligaments which pass through it.

The membrane produces synovial fluid which lubricates the joints Shoulder Joint Ligaments are tough fibrous bands of tissue which connect bone to bone and help stabilise a joint, the strongest ligament in the body being situated at the front of the hip capsule, preventing excessive backward movement of the legs.

Ligaments, although stronger than muscle tissue, have fewer nerve endings and less blood supply, and therefore take longer to repair when damaged.The major muscles of the shoulder, their primary function, and their innervation are listed in Table Flexion.

Shoulder flexion is conducted primarily by the anterior deltoid (C5-C6) and coracobrachialis (C5-C6) with assistance by the clavicular head of the pectoralis major (C5– T1) and biceps (C5-C6).

PowerPoint Slideshow about 'Chapter The Muscular System Biol A&P' - moses What are the principle axial muscles of the body, their origins, insertions, actions, and innervation?The Axial Muscles. What are the principal appendicular muscles of the body and their origins, insertions, actions.

The back anatomy includes some of the most massive and functionally important muscles in the human body. Still, many individuals pay far too little attention to them.

The back muscles enable you to stand up straight; support and protect your spine; and reach, pull and extend your arms and torso. The muscles of respiration are also called the 'breathing pump muscles', they form a complex arrangement in the form of semirigid bellows around the lungs.

All muscles that are attached to the human rib cage have the inherent potential to cause a breathing action.
