Do Now: Map of Sensory Nerves

Important AnnouncementsLast week…•  The Human Neuron (role play)•  Lab: Mapping Sensory NervesThis week…•  Map of the Brain •  The Peripheral Nervous System•  Vocabulary Quiz #5 Neurons and Brain Anatomy

Next week…•  Nervous System Foldable•  Quiz: The Nervous System

Objective

Describe the major functions of the cerebrum cerebellum and brain stem.

Standard AP 4.7

Discuss the components (parts) and major functions of the brain stem, cerebrum and the cerebral cortex.

Review…Lab: Mapping Sensory Nerves

– Read and annotate page 1.– Answer the PreLab Questions

(including 2 checking for understanding questions)

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 ,

, and .

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

• Medulla Oblongata– Extension of spinal cord– Vital centers

• (breathing, heart rate, blood vessels)
