The elbow joint is a hinge joint. Joints that allow movement are called synovial joints. A synovial joint s adapted to enable a joint to move easily. They contain cartilage, ligaments, bones, synovial fluid and a synovial membrane. Slide six The bones provide the solid base on which the tendons and ligaments are fixed.
Most skeletal muscles are attached to bones or joints so that the muscle can either expand or contract to create motion. They consist of band like fibers attached and bundled together that run along the bone. These fibers are held together by connective tissue called epimysium, which also protects the muscle. Skeletal muscle is what makes the body able to walk and move, without these skeletal muscles the body could not function properly because it would have nothing to rely on for stabilization and strength. They contain what is called striated cells, which is cells that are shaped like bands and are individual, they stretch out the length of the muscle so that they are able to contract with it and these cells are also what give the muscle energy through respiration of proteins fats and glucose which is the energy supplement for all muscles.
The musculoskeletal system provides the ability for movement with bones, joints and the skeleton all working together. The nervous system provides the five senses and one of the commutation systems in the human body. I believe that the musculoskeletal system is the better of the two in the human body. I think this because everyone needs a skeleton for their body to even stand. The muscles help contract for movement.
Skeletal muscles play a huge role in the way our bodies function because without muscles, our bones would not properly be held together. Most of the body’s muscle tissue is skeletal muscle. It interacts with the skeleton to move body parts. It’s long, thin cells are called fibers and they have more than one nucleus. Their structure gives them a striped look.
As one muscle in the pair contracts the other one relaxes, creating movement. The human body is made up of many different muscle pairs, though some are more important than others. Examples of three major muscle pairs are the biceps and triceps for bending and straightening the elbow, the quadriceps and hamstrings for bending and straightening of the knee, as well as the deltoids and lattisimus dorsi for lifting the arm and lowering the arm. 2. Describe the structure of skeletal muscles.
The muscular and skeletal systems work together to enable body movement and stability, this is called the musculoskeletal system. When muscles contract, they pull on bones of the skeleton to produce movement or hold the bones in a stable position. The shape of the bones and how they fit together at the joints allows for different types of movement. For example, the leg bones come together at the knee to form a hinge joint that enables the knee to bend back and forth. Whereas, your shoulder can move freely, meaning it has a ball and socket
Types of muscle. 1 Chapter 1 Introduction Skeletal muscle is striated muscle tissue that is attached to bones. It is composed of fibers that look like a mixture of dark and light bands bundled together that run along the bone. These muscles are responsible for relaxing and contracting when a person moves. Skeletal muscles are the muscles that can be seen and feel through our skin.
One of the primal movers of arm abduction along the frontal plane is the deltoid muscle found in both minks and humans. In both species, deltoid muscles allow for the abduction of the humerus. The next two muscles are the biceps brachii and its opposing muscle the triceps brachii. The biceps brachii consists of two heads, which arise from the scapula and join to form a single muscle that ends upon the upper forearm. The most important functions of the biceps brachii are the supination of the forearm and the flexing of the elbow.
Normal dense connective tissue contains collagen fibres in one direction to provide strength, it is found in tendons and ligaments in which the tendons connect muscle to bone and the ligaments connect bone to bone. The cells of a cartilage are strong but flexible and also contain collagen and elastic fibres. It does not stretch and can resist compression but maintains its shape. It is found at the ends of bones where it prevents friction within the joints. Blood is also a connective tissue and also contains cells that are separated by a non-living material such as the plasma.
It supports the internal organs that are held within the body in a network of tissue. Bones give us form. In sports support and shape are also used for example in a rugby scum, to body needs to be placed in such a way to keep the back aligned. [IMAGE] Movement/ Attachment: The skeleton is jointed to allow movement. A joint is an articulation of two or more connecting bones, providing us with either stability or movement.
