uk/heart-health/conditions/familial-hypercholesterolaemia How CHD affects the body CHD can affect the body as it can reduce the oxygen supply due to narrowed arteries which can result in you feeling physically exhausted and stressed a lot. It can also cause pain and shortness of breath. Not having enough oxygen can also result in a series of heart attacks which can lead to the heart muscle dying and being replaced with scar tissue. https://www.sharecare.com/health/heart-disease/how-coronary-heart-disease-affect

------------------------------------------------- LIST OF MUSCLE INJURIES Properly functioning muscles perform only one duty‚ contraction. Muscles enable the body to sit‚ to move and to stand upright. They are attached by way of tendons to bones. Their contraction is controlled by electrical signals that can either be voluntary‚ such as when a person decides to stand up‚ or involuntary‚ as with the muscles that expand and contract the chest to control breathing. Muscles are made of thousands of muscle fibers. Knowing the types

Stress can really affect your body‚ mind‚ and behavior. It is a normal response to situations that make you feel upset or threatened in a way. Stress is the body’s way of change. The change can either be good or bad. Stress affects your health without you even realizing it. Constant headaches or trouble sleeping would be something stress causes often

isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object‚ conducted the first muscle experiments between 1661 and 1665. Later‚ between 1737-1798 Luigi Galvani determined that frog muscle responded to electrical currents. The kymograph‚ which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The muscle cell or fiber is the basic unit of a muscle. The frog gastrocnemius

What happened to the number of fibers contracting as the current was raised from threshold to that required to produce a maximal contraction? 5.

MECHANICAL PROPERTIES OF SKELETAL MUSCLE USING FROG GASTROCNEMIUS AIM The purpose of this experiment was to demonstrate the physiological as well as mechanical properties of skeletal muscle using the gastrocnemius muscle of a frog by exploring five different investigations namely the single twitch‚ the graded response‚ the relationship between muscle length and tension‚ muscle tetanus‚ and muscle fatigue. These individual experiments aim to explore the way muscles can contract when an electrical stimulus

listening to music can affect the body and brain. Specific Purpose: To inform the audience as to how music can affect the moods of an individual‚ the brain function‚ productivity‚ and stress and anxiety. Thesis: Listening to music is a very popular and common activity among many people of all ages‚ and while most people listen mindlessly without thinking about the effects it has on our body‚ music plays a huge role in how our brain functions‚ our moods and health‚ and how we go about life.

for rotation around an axis. There is a pivot joint near the top of your spine that allows your head to move from side to side. Hinge joints. This type of joint can open and close like a door. Your elbow is a hinge joint. Your biceps and triceps muscles are basically two people standing on opposite sides of a wall (the humerus‚ or upper-arm bone)‚ each with one hand reaching over to its respective side of a door (the bones of the lower arm). The biceps "shuts" the door‚ by contracting and lessening
