1. Thurs Sept 29 and Fri Sept 30 Objective: Students will explain imaging techniques and genetic disorders. 1.CBM – keep as study tool 2.Imaging techniques 3.Genetic disorders 4.Review videos

2. Imaging Techniques EEG CAT Scan MRI fMRI PET Transcranial ultrasound

3. Genes Transmission by biological processes 23 pairs of chromosomes Gene – determines trait

4. Chromosomal Abnormalities Turner’s Syndrome – A baby is born with just a single X chromosome (girls) – Shortness, webbed neck and lack of ovaries and secondary sex characteristics Klinefelter’s Syndrome – A baby is born with and extra X (XXY) (boys) – Minimal sexual development and extreme introversion Down’s Syndrome – A baby is born with and extra chromosome on the 21 st pair – Rounded face, shorter fingers, low cognitive ability

5. Recessive Gene Disorders Tay-Sachs Syndrome – Progressive loss of nervous function – Eventual death Albinism – Failure to synthesize or store pigment – Abnormal nerve pathways to the brain – inability to perceive three dimensional Phenylketonuria (PKU) – Severe, irreversible brain damage if not fed special diet for first 30 days after birth – Lacks ability to process amino acid

6. Dominant Gene Disorders Huntington’s Disease – Degeneration of nervous system – Forgetfulness, tremors, jerky motions – Loss of ability to talk – Personality changes
