Biology Exam Flashcards
What is atrophy
wasting away of body tissue or an organ, especially as a result of the degeneration of cells.
What is hypertrophy
An enlargement of an organ or tissue in response to an increase in the size of its cells
What is hyperplasia
the enlargement of an organ or tissue caused by an increase in the reproduction rate of its cells, often as an initial stage in the development of cancer.
What is metaplasia
abnormal change in the nature of a tissue
What is dysplasia
the presence of cells of an abnormal type within a tissue, which may signify a stage preceding the development of cancer
What is apoptosis
the death of cells which occurs as a normal and controlled part of an organism’s growth or development
What is necrosis
the death of most or all of the cells in an organ or tissue due to disease, injury, or failure of the blood supply.
Define and describe Pharmacodynamics in detail
Pharmacodynamics is the branch of pharmacology concerned with the action of drugs on the body or on microorganisms within or on the body; and how the drug binds to receptors.
Define and describe Pharmacokinetics in detail
Pharmacokinetics is the scientific study of how the body processes drugs and is normally broken down into 4 stages: Absorption, Distribution, Metabolism and excretion.
What is Bioavailability
The proportion of the administered dose which reaches the systemic circulation.
What is Therapeutic Range or Therapeutic index
The difference between the level of a drug in the blood to be effective and the level where the drug becomes toxic.
What is the definition of commensal microorganisms
A microorganism that lives harmlessly (usually) on the skin
What is Aetiology
The scientific study of the causes of disease.
Identify the signs and symptoms of inflammation (see Ashelford et al P36).
Redness. Heat. Swelling. Pain. Loss of function
provide a biological rationale for inflammation (see Ashelford et al P36).
1) The release of Inflammatory mediators
2) A vascular response
3) A cellular response
Describe the acute inflammatory processes with reference to cellular physiological and pathophysiological detail. (Ashelford et al, chapter 2).
.
Describe chronic inflammatory processes with reference to cellular pathophysiological detail (Ashelford et al, chapter 2).
.
Discuss inflammation and corticosteroids (Ashelford et al, P43).
.
Discuss inflammation, pain and Non-Steroidal Anti-inflammatory Drugs (NSAIDs) ((Ashelford et al, P152) and demonstrate an awareness of potential side effects and contraindications.
.
List the innate immune system defences against infection (Ashelford et al P77)
.
Demonstrate a general understanding of the adaptive immune system response to infection (Ashelford et al P76 to P89).
.
Provide a short account of the types and characteristics of potentially infectious organisms (See Ashelford et al P54 to P59).
.
Demonstrate a detailed understanding of the mechanism of action of antibacterial drugs (Ashelford et al P65).
.
Describe antimicrobial resistance at a cellular level, and account for the effects of healthcare behaviours (Ashelford et al P67 to P70.
.
Describe the components of the pain experience including transduction, transmission, perception and modulation (see powerpoint slideset on Moodle and Ashelford et al P139 -P147).
.
Identify types of pain (see Ashelford et al essential textbook P149) including nociceptive and neuropathic pain types and provide a brief description of how these may occur.
