PLAN • Identify major regions of the human brain. • Evaluate patient family history as part of a medical exam and create a pedigree. DO • Discuss Jack Brandon’s diagnosis, test recommendations and analysis, and follow-up plans • Discuss and draw a pedigree for Jack Brandon’s family • Answer the remaining Conclusion questions • Practice Brain Anatomy Quiz

Pedigree Analysis • Method used to study the inheritance of genes in humans. • Can be used to indicate a possible diagnosis of a genetic disorder.

Pedigree Symbols • Symbols are used to represent family members.

Pedigree for Jack Brandon Jack’s mom Jack’s sister Jack’s dad Jack’s wife Jack’s daughter

Optional Extension • The ability to roll your tongue is a genetic trait. • As homework draw a pedigree for your family and for the trait of tongue rolling. • If the individual can roll his or her tongue, color in the symbol.

PLAN • Identify major regions of the human brain. • Evaluate patient family history as part of a medical exam and create a pedigree. DO • Brain Quiz • Complete a medical history form for sick patient Jack Brandon and do research to make a diagnosis.

Mystery Disease Diagnosis • You will work at your table as a team. – Complete medical history form for patient – Research to make a diagnosis – Test Recommendations to confirm diagnosis – Explain results of tests (Laboratory Analysis) that would be positive for the disease – Follow-up plans (treatment, counseling, etc. ) • STAY ON TASK – DISCUSSION OF PATIENT ONLY • Any work not completed during class is homework for tonight.
