Compare and contrast cardiac and smooth muscle. In cardiac muscle‚ each heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms

always propagated in a micro way‚ tissue culture is the most popular method for micro-propagation in Alstroemeria. Tissue culture involves the use of small pieces of plant tissue (explants) which are cultured in a nutrient medium under sterile conditions. Using the appropriate growing conditions for each explant type‚ plants can be induced to rapidly produce new shoots‚ and‚ with the addition of suitable hormones new roots. Alstroemeria explants used in tissue culture consist of a rhizome

Nutritional requirements The composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro

coarsely controlled muscles. Explain how motor units act to establish muscle tone. What are the functions of muscle tone? Motor Unit- One motor neuron and all the muscles it innervates. Each muscle will respond to one motor nerve which contains axons that can have up to 100’s of neurons that branch into terminals that form NMJ with ONE fiber. When a motor neuron sends an action potential‚ it will cause all of the connected muscle fibers to contract. The number of muscle fibers per motor unit

What is the difference between compact and spongy bone? (2 points) Bone tissue is composed of bone cells and extracellular matrix. It is continuously remodeling its extracellular matrix according to the stresses placed upon it. It has a lot of blood flow and it is supplied by the nervous system. The bone cells includes; Osteocytes‚ osteoblasts

Muscle Fatigue Coursework What Is Muscle Fatigue and How Does It Occur? Muscle fatigue is a condition in which muscles cannot exert their normal force. Muscle fatigue occurs when the muscles cannot exert normal force‚ or when more effort than normal is required to achieve a desired level of force. There are a number of causes for muscle fatigue‚ ranging from exercise-induced fatigue to genetic conditions which lead to muscle weakness. Doctors and researchers have conducted a number of studies
