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
Imaging Techniques
•
•
•
•
•
•
EEG
CAT Scan
MRI
fMRI
PET
Transcranial ultrasound
Genes
• Transmission by biological processes
• 23 pairs of chromosomes
• Gene – determines trait
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 21st
pair
– Rounded face, shorter fingers, low cognitive ability
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
Dominant Gene Disorders
• Huntington’s Disease
– Degeneration of nervous system
– Forgetfulness, tremors, jerky motions
– Loss of ability to talk
– Personality changes
