💡 Big idea: Direct examination of brain anatomy connects textbook region names to three-dimensional structures and reveals why different injuries produce different functional deficits.
- 0-10Safety briefing and handling protocol for sheep brain or virtual login
- 10-25External examination: identify cerebrum, cerebellum, brainstem; note one function each
- 25-45Internal (coronal) cut: locate gray matter and white matter
- 45-60Draw and label brain-region map: three regions with functions; gray/white matter boundary

- 75-80Submit labeled map; clean up specimen or log off virtual
- • Today you examine a real or virtual brain. This is the most direct way to understand why region location matters.
- • You are looking for three regions and the boundary between gray and white matter. Those four observations go on your brain-region map.
- • Handle the specimen with care and with dignity. This is a real nervous system that ran a real animal for years.
- • Your map today becomes the reference for Thursday when we connect those regions to the CNS and PNS organization.
- 1Review the safety and handling steps for the sheep-brain or virtual model.
- 2Identify the cerebrum, cerebellum, and brainstem on the specimen.
- 3Note one function controlled by each region you identify.
- 4Compare the external and a cut internal view to locate gray and white matter.
- 5Submit your labeled brain-region map with functions.
- • You can locate the cerebrum, cerebellum, and brainstem.
- • You can state one function for each region.
- • Cerebrum: largest region; controls voluntary movement, sensory processing, language, memory, and higher cognition. Divided into four lobes (frontal, parietal, temporal, occipital).
- • Cerebellum: located posterior to the brainstem; coordinates balance, fine motor control, and learned movement sequences.
- • Brainstem (medulla oblongata, pons, midbrain): controls autonomic functions including heart rate, respiration, and blood pressure; connects brain to spinal cord.
- • Gray matter contains neuron cell bodies; white matter contains myelinated axons. On a cut surface, gray is darker and peripheral, white is lighter and central (in the cerebrum).

Day 3 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Complete the brain-regions task in Lesson 2.1 Getting Nervous on myPLTW that accompanies today's dissection or virtual brain; match structures to functions.
Mark the brain-regions task complete after submitting your dissection notes or virtual-brain annotation.
Neuron task is done; today the brain-regions task should show complete.

Vetted readings and references for this unit. Use them to prepare, to catch up if you were absent, or to go deeper on today's target.
Lab & supplies
- • Wear gloves, goggles, and apron for the entire real dissection; do not remove PPE until specimen is returned to the tray and hands are washed.
- • Use scalpel or scissors only when directed by the teacher; cut away from your body and your lab partner.
- • Preserved specimens contain fixative chemicals; avoid touching your face during the lab and wash hands thoroughly with soap afterward.
- • Dispose of all specimen tissue in the designated biohazard bag, not the regular trash.
