Chapter 3 delves into the intricate mechanisms of chemical signalling by neurotransmitters and hormones within the nervous system. It begins with the basic concepts of synaptic transmission, highlighting the directionality from presynaptic to postsynaptic cells and the structural components of synapses, such as axodendritic and axosomatic synapses. The chapter further explores neurotransmitters' synthesis, release, and inactivation, noting the diverse chemical classes, including amino acids, mon...

OCR A-Level Biology Questions And Verified Answers With Complete Answers| Graded A| What is the MAIN role of membranes and what are the other roles? Correct Answer -COMPARTMENTALISATION -site of chemical reactions -cell signalling -cell adhesion How do cell membranes compartmentalise? Correct Answer Membranes are hydrophobic layers that separate different regions of substances dissolved in water. This hydrophobic layer acts as a barrier preventing the movement of hydrophilic molecules f...

Homeostasis - Body's ability to maintain dynamic steady state of internal balance Hyperplasia - Increased number of cells Hypertrophy - Increased size of cell Atrophy - Reduced size of cell Metaplasia - Replacement of one cell type with another that can better endure stress but not as effective as original tissue. i.e. scar tissue, callous Dysplasia - Abnormal cell growth results in abnormal size shape or appearance, precedes cancerous changes Free radical injury Hypoxic cell...
