To achieve P4 I will be describing the structure and function of the muscular system.
The muscular system is made up of the muscles in the body, there are more than 600 and tendons that connect them to the skeleton.
Function

Movement
Skeletal muscles are arranged in pairs on opposite sides of joints. As one muscle contracts, the opposing muscle must relax to cause movement.
Posture
Muscle are also needed to provide stability to the body. It is kept with the contraction of muscles e.g
Heat

Many skeletal muscles contract isometrically in order to stabilise and look after active joints during movement.
There are three different types of muscle these are called cardiac, skeletal and smooth.

Cardiac
Skeletal (voluntary)
Smooth (involuntary)
These muscles are found only in the walls of the heart. These muscles fibres are short and striated and contract automatically and rythmatically. Also they do not tire and work continuously through life. If these muscles where to stop it would cause death
These are attached to the bones of the skeletal system and move voluntary by control of the brain and nerves. In appearance these are striated they work hard but tire easily.
These are found in the walls of the digestive system, blood vessels and urinary system they are a spindle shape cells that interlock. Smooth are not striated and are regulated by the automatic nervous system (ANS). It is capable of slow but sustained contraction and does not tire easily.

The muscle that is contracting

Anatomy and Physiology - task 3: Report The muscular system is responsible for the movement of the human body. There are about 700 named muscles that are all attached to the skeletal system and they make up roughly half of a person’s body weight. There are three different types of muscle tissue: Cardiac, Skeletal and Smooth. 1. Cardiac Muscle. Cardiac muscle is only found in the heart, and is responsible for pumping blood around the body. You cannot control cardiac muscle consciously and therefore…

Anatomy And Physiology Of Bones

Chap. 7 1. Compact bone: also called cortical bone. Dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces. Spongy bone is less dense, lighter than compact bone. Looks like a sponge. No osteons. 2. Intervertebral discs, pubic symphsis, cartilage pads of the knee 3. Calcium and phosphates. Calcium is used for muscle contraction, blood clotting, and nerve impulses and keeps bones strong. Phosphates is required for ATP utilization…

Explain The Anatomy And Physiology Of Cosmetology

1. The study of anatomy, physiology, and histology is important to cosmetologists because you need to know certain parts of the body to be able to understand how they work. 2. Anatomy is the study of the human body structures that can be seen with the naked eye and how the body parts are organized; it is the science of the structure of organisms or of their parts. Physiology is the study of the functions or activities performed by the body's structures. Histology, also…

Anatomy & Physiology Essay

The food’s nutrients are now being absorbed in to the blood, and the veins from ileum are now draining into superior mesenteric vein. Superior mesenteric vein and the splenic vein then combine and form hepatic portal vein where it leads to the liver. The portal venous system located in the liver is delivering blood to the capillary system. From there, blood is now flowing up into the inferior vena cava and to the right atrium, from there down to the right ventricle and then down to the pulmonary…
