Review…Lab: Mapping Sensory Nerves
Analysis Questions1. What does it mean to feel a 1 or a 2?2. More 1’s = less sensory nerves
• Receptors are farther apart3. More 2’s = more sensory nerves• Receptors are closer together

Checking for Understanding1. What are the two divisions of the cerebrum? 2. The most superficial layer of the cerebral
cortex made up of matter.3. The deepest layer of the cerebral cortex made
up of matter.4. The four lobes of the brain are the ,

Cerebellum• Second largest
part of the brain • Coordinates the
action of muscles– balance

Diencephalon• Thalamus
– Sensory information• Hypothalamus
– Control center for thirst, hunger, anger, fatigue and temperature
– Regulates pituitary gland – “master gland”

Brain Stem• Midbrain
– Auditory pathways – (turning head toward a loud noise)
– Visual pathways – (constricting and dilating pupils)
• Pons “The Bridge”– Relays information from cerebrum to
cerebellum
