makes our joints move quickly‚ so there needs to be more synovial fluid in the joints to allow and assist this movement When we start to warm up: • The muscles need energy in the form of glycogen to make the sarcomeres contract. – So the heart (cardiac muscle) beats faster to provide the glycogen to the muscles via the blood. • The conversion of chemical energy (from the Glycogen) to movement (contraction of the

Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces

Body Systems of Various Organisms All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans‚ pigs‚ crayfish‚ and earthworms. From their mushy‚ gushy organs to their soft‚ gentle skin‚ you may think‚ “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be‚ but in other ways‚ they are very much alike

genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles‚ which are used for movement‚ and heart (cardiac) muscle. These forms of muscular dystrophy occur almost exclusively in males. Duchenne and Becker muscular dystrophies have similar signs and symptoms and are caused by different mutations in the same gene. The two conditions differ in their severity

muscle‚ cardiac muscle‚ and skeletal muscle. Smooth muscle is located in the digestive tract and in the walls of blood vessels. It moves food through the digestive system. Cardiac muscle is found only in the heart. This muscle pumps blood throughout your body. Skeletal muscle is attached to your bones to help you move. Muscle action can be voluntary or involuntary. The muscles that you control are voluntary and the muscles that you do not control are involuntary. Smooth muscle and cardiac muscle
