Chapter 1 - The Human Body Anatomy is the science relating to the structural organisation of living organisms. Physiology is the science relating to the operational functions of living organisms. The many parts and systems of the body are integrated and function co-operatively to provide a healthy living body via 6 hierarchy levels of structural organisation. The basic or first level is the Chemical Level‚ where atoms are combined to form molecules. The second level is the Cellular Level

department‚ an ECG and cardiac enzymes were obtained. The cardiac monitor showed sinus tachycardia with occasional premature ventricular complexes. K.R. was treated with 2 L nasal oxygen‚ tissue plasminogen activator‚ sublingual nitroglycerin‚ and IV morphine sulfate. When he was pain free‚ he was transferred to the cardiac unit for monitoring. Discussion Questions 1. What changes in “cardiac enzymes” would be consistent with a diagnosis of MI? Troponins(I and T specific to cardiac muscle cells)‚ elevated

The courts‚ judges‚ defense and prosecuting attorneys and probation personnel weigh these risks and balance them with the best interests of the probationer and victim. Usually‚ probation personnel monitor high-risk offenders closely through home arrest or electronic monitoring. Then there is the problem of victim concerns. Victims vary widely

BTEC Level 3 Certificate in Sport Unit 1- Principles of Anatomy & Physiology in Sport Assignment 1 of 3 Muscular system Muscles Skeletal‚ cardiac and smooth are the three main types of muscle in the body. Skeletal muscle is a voluntary muscle‚ this means that it is under control by the somatic nervous system. When viewed under a microscope the appearance of this muscle is striped/ striated. “The primary function of the skeletal muscle is to produce fine movements to keep you alive. Skeletal

----------------------- The Atrioventricular Node (AVN) • This is the node that involves both the atria and ventricles. • The AVN is deep in the centre of the heart muscle. • It picks up the wave sent by the SAN and delays it by about 0.1s to let the atria finish contracting before the AVN sends the second wave. • The AVN uses the Purkyne tissue (a conducting tissue) to the apex. • The wave is sent up through the ventricles making them contract‚ pushing the blood through the semilunar valves

Q1 Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine‚ the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through
Premium Skeletal muscle Myosin Action potential
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

About 300 soft bones. they turn into 206 adult solid bones- If we can have a strong core – and deep abdominal muscle called “tranferus abdomenus”- wraps around your core- because it wraps around when it tightens ‚ it tightens up around the spine and gives it a lot of stability- the spine ( a whole lot of bones sitting on top of each other) we don’t want
