Differentiate mitosis from meiosis
Mitosis is nuclear division, which ultimately leads to diploid somatic cells. Meiosis is nuclear division which ultimately leads to haploid gametes (half no. of chromosomes)
Mitosis: generation of two identical daughter cells Meiosis: generation of one to four non-identical gametes sperm or ova
What are the borders of the inguinal canal (roof, floor, anterior, posterior)
Roof: Internal oblique and transversus abdominus
Floor: Inguinal ligament
Anterior: Aponeurosis of external oblique
Posterior: Transversalis fascia
Explain the pathophysiology of Cystic Fibrosis
Mutations in the CFTR gene resulting in a decrease of epithelial chloride channels. This alters ion transport resulting in decreased osmotic flow into secretions, causing them to thicken
What 2 classes of genes control the cell cycle, and give an example of both
Oncogenes: HER 2
Tumor supressor genes: TP53
List and describe 2 possible causes of down syndrome
Non-disjunction: Failure of seperation of homologous chromosomes during meiosis (Non-Inheritable)
Robertsonian translocation: Translocation of the long arm of chromosome 21 onto the long arm of chromosome 14
Briefly describe 3 ways the body can maintain energy levels during starvation
Glycogenolysis: Breakdown of stored glycogen
Gluconeogenesis: Creation of glucose from non-carbohydrate sources
Ketoacidosis: Beta oxidation of FFA's into ketone bodies
List 4 things that can imrpove disease screening for Indigenous Australians
Consistency with clinicians
Adaptabilty of appointment times
Adapting health information for health literacy levels
Collaboration with Indigenous members
Differentiate a carcinogen from a mutagen
Mutagen: A physical or chemical agent that changes genetic information and increases the frequency of mutations above the natural background level
Carcinogen: An agent directly involved in the promotion of cancer or facilaition of its progression
