INTRODUCTION Give a brief description in your own words of the objectives and aims of this practical. The aim of this practical is to investigate how the autonomic nervous system (ANS) affects the motility in the gastrointestinal tract‚ by experimenting with the release of neurotransmitters. A. RESPONSES TO NERVE STIMULATION Attach a copy of your experimental recordings showing a period of spontaneous contractions and the response to stimulating the nerves

Disscusion In this experiment‚ we are required to observe‚ explain‚ identify and recognize the phylum under Kingdom Animalia. The phylum that we need to identify was Phylum Porifera‚ Phylum Cnidaria‚ Phylum platyhelminthes‚ Phylum Nematoda‚ Phylum Rotifera‚ Phylum Mollusca‚ Phylum Arthropoda‚ Phylum Echinodermata‚ Subphylum Cephalochordata and Subphylum Vertebrata (Fishes). Phylum Porifera The characteristic of members of Phylum porifera include asymmetrical or radial symmetry body plan. There

HBS ECA Study Guide UNIT 1 1.1.2 Directional terms describe the position of anatomical structures in relation to other structures or locations in the body and regional terms specify specific anatomical landmarks on the body. Students review on own. 1.2.1 A tissue is a group of similar cells designed to carry out a specific function. What are four main tissue types and how does structure lead to function? How does the structure of epithelial tissue lend this form of tissue to its function?

Chapter I Introduction to Psychology Wilhelm Wundt Psychology started as a branch of philosophy in 300 B.C. with the great precursors like Plato‚ Aristotle‚ Socrates‚ St. Augustine and etc. The first psychological laboratory was established by Wilhelm Wundt in Leipzig‚ Germany and He made himself the “father of experimental psychology”. Psychology is the scientific study of behaviour and mental processes. Behaviour is anything that a person or animal does‚ feels‚ thinks or experiences
