DESCRIPTION
TYPES OF MUSCLES The cardiac muscles is the muscle of the heart itself. The cardiac muscle is the tissue that makes up the wall of the heart called the mydocardium. Also like the skeletal muscles, the cardiac muscle is striated and contracts through the sliding filament method. However it is different from other types of muscles because it forms branching fibers. Unlike the skeletal muscles, the cardiac muscle is attached together instead of been attach to a bone.

ALL THE KIND MUSCULARDid you know you have more than 600 muscles in your body? They do everything from pumping blood throughout your body to helping you lift your heavy backpack. You control some of your muscles, while other like your heart do their jobs without you thinking about them at all.
Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle.
TYPES OF MUSCLES
The cardiac muscles is the muscle of the heart itself. The cardiac muscle is the tissue that makes up the wall of the heart called the mydocardium. Also like the skeletal muscles, the cardiac muscle is striated and contracts through the sliding filament method. However it is different from other types of muscles because it forms branching fibers. Unlike the skeletal muscles, the cardiac muscle is attached together instead of been attach to a bone.
BODY SYSTEM
• The skeletal muscle makes up about 40 % of an adults body weight. It has stripe-like markings, . The skeletal muscles is composed of long muscle fibers. Each of these muscles fiber is a cell which contains several nuclei. The nervous system controls the contraction of the muscle. Many of the skeletal muscle contractions are automatic. However we still can control the action of the skeletal muscle. And it is because of this reason that the skeletal muscle is also called voluntary muscle.
MAJOR ORGANS • Liver - Keeping muscles supplied with energy, the liver can feed glucose to the
bloodstream by breaking down hepatic energy
• Kidney -Healthy kidneys keep the acid-base balance in a range ideal for the metabolic reactions on which muscle contraction depends on
• Brain - The brain's sensorimotor cortex and brainstem transmit impulses via two neural pathways that maintain healthy muscle tone
