There are three types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal

Experiment Results Predict Question: Predict Question 1: Make a prediction about the basal metabolic rate (BMR) of the remaining rats compared with the BMR of the normal rat you just measured. Your answer : c. The BMR of both remaining rats will be lower than the normal rat’s BMR. Predict Question 2: What do you think will happen after you inject thyroxine into the three rats? Your answer : a. The normal rat will become hyperthyroidic and develop a goiter. Predict Question 3: What do you think

The anatomy of the spinal cord is very unique. Externally‚ it is initially surrounded by the vertebral column. The vertebral column is divided into the cervical‚ thoracic‚ lumbar‚ sacral‚ and coccygeal regions. These different vertebrae protect the spinal cord from damage and form a type of shell around it. The spinal cord appears as a long‚ thin cord of nerves. The peripheral nerves that extend out to many parts of the body arise from the spinal cords thirty-one segmental pairs of nerves. The cervical

The study of cardio physiology was broken up into five distinct parts all centering on the cardiovascular system. The first lab was utilization of the electrocardiogram (ECG). This studied the electrical activities of the heart by placing electrodes on different parts of the skin. This results in a graph on calibrated paper of these activities. These graphs are useful in the diagnosis of heart disease and heart abnormalities. Alongside natural heart abnormalities are those induced by chemical substances

Musculoskeletal response: Increase blood supply: The increase in blood supply might happen as your body starts to work more efficient than usually . The blood supply has to increase because the blood has to go to the parts in your body which you are exercising the most .For example: If you go for a run‚ the blood supply will increase because your legs will need more energy‚ therefore there will be more blood going into your legs than normal because you are overworking them. Increase in muscle
