These four programmes each deal with a specific experiment and are presented in two sections: the theory is explained then a demonstration follows of how to perform the reaction in the laboratory....
Designed to support A-level physics courses, each programme enables students to make observations and readings as if they were performing experiments in the laboratory. Titles of individual programmes are:...
Demonstrates how to measure the rate of photosynthesis in a disc of leaf and a suspension of chloroplasts using an oxygen electrode. Shows two different types of oxygen electrode and oxygen output is...
Shows the respiratory and other reflexes present in the decerebrate cat. Emphasis is placed on the somatic brainstem reflexes, including respiratory response to carbon dioxide, cough reflex and swallowing....
Preparation: guinea pig ileum. Describes the isolated organ response recording technique and includes setting up procedures of the mammalian intestine preparation, the principles of isolated organ...
Studies effects of autonomic drugs and blocking agents on the components of the cardiovascular system in vivo. The cardiovascular system of an animal is a closed system in which a pump (the heart) forces...
Preparation: rat phrenic nerve diaphragm. Gives a detailed historical background to the discovery of muscle relaxant drugs and summarises the results of the early experiments conducted by Claude Bernard. The...
Demonstrates the effect of autonomic drugs on the isolated perfused mammalian heart. The mammalian heart is innervated through both the sympathetic and parasympathetic nervous system and will therefore...
Demonstrates the responses of the cat to blood pressure changes including heart rate and the smooth muscle responses of the nictitating membrane. Shows the sympathetic nerve innovation and the effects of...
Preparation: guinea-pig ileum. Non-competitive antagonism can arise from either non-equilibrium receptor blockade or inhibition of an intracellular process distal to the site of agonist receptor action. The...
